    1.What Is A Shrink Film?

    Shrink Film

    Shrink film is a strong, durable, and stretchable polymer that is used to wrap around goods and products to protect them. It is made of polymer based plastic which includes polyvinyl chloride (PVC), polyethylene, and polyolefin.

    Shrink film works on the basis of the heating process. The film is heated at a certain temperature with the help of an electric gun, gas heat gun or a conveyor heat tunnel.  As a result, the film tightly adheres to the product, enclosing it and protecting it from any damage. This film can be used to wrap various kinds of products such as bottles, food products, consumer goods, etc.

    2.What Is A Stretch Film?

    Stretch Film

    Stretch film is a thin elastic polymer used to wrap around pallets or boxes. It is primarily made up of linear low density polyethylene, resins which are obtained from petroleum industry. These films easily enclose the goods inside, protecting it from any harm or damage during shipping, storage and distribution process.

    Since the stretch film is transparent, the goods inside can be easily identified or scanned, making its use extremely convenient. They are highly versatile and come various designs, shapes, sizes and length which can be customized according to the customer’s needs.

    3.What Are The Differences Between Shrink Film And Stretch Film?

    Differences Between Shrink Film And Stretch Film

    The shrink and stretch films are not only ideal for wrapping boxes, products and other consumer goods but also serve as a protective barrier against the external environment or any kind of damage. Despite these similarities, they have a major difference which involves heating. In shrink film, heating is applied to the film. After cooling, the film shrinks around the item more tightly, forming a protective layer over the item which can then be sent for shipping. Moreover, it does not have the capability to stretch unlike the stretch film.

    In stretch film, no heating is applied and the elastic film is wrapped around the box tightly. This film has the capability to stretch by 300% and when it tries to come back to its original shape, it firmly grasps the box it is wrapped around.

    4.What Are The Types Of Shrink Film?

    Shrink film consists of 3 types known as polyvinyl chloride (PVC), polyethylene and polyolefin. Let us discuss each type below.

    Polyvinyl chloride ( PVC )

    Polyvinyl chloride

    Polyvinyl chloride is well known to be lightweight, versatile and for its relatively cheap cost. It is one of the most common material to package goods due to its durability and effectiveness. It can be used for a number of products such as toys, furniture, bags, electrical appliances etc.

    Polyolefin

    Polyolefin

    Polyolefin is the strongest and the most durable type of shrink film available out there. Due to its high strength it is an excellent choice for goods which require high quality protection against any damage. They are used in various industries to make products such as caps, face masks and high performance filters.

    Polyethylene

    Polyethylene

    Polyethylene is just like polyolefin except it contains ethylene which undergoes polymerization. It can be molded into various flexible packaging to make products like bottles, toys, bags etc. polyethylene itself has 3 forms known as high-density polyethylene, low-density polyethylene and linear low density polyethylene.

    5.What Are The Types Of Stretch Film?

    Stretch film has 2 common types known as hand stretch and machine stretch film. Let us discuss each type below.

    Hand stretch film

    Hand stretch film

    Hand stretch film, as the name suggests is used to manually package goods. This film has smaller width as compared to machine stretch film in which the worker manually wraps the film around the concerned item. It is ideal for small scale businesses where the workshop or warehouse deals with low volume goods rather than high volume ones since the packaging is done manually, thus making the process time consuming.

    Hand stretch film is further divided into 3 categories

    • Blown hand film stretch: ideal for heavier items due to its load bearing property and high resistance.
    • Cast hand stretch film:  this type should be used when there is a need for tear resistance and superior puncture when the goods are being transported from one place to another.
    • Banding hand stretch film: this film offers extremely resistant cling for top banding pallets and is ideal for packaging smaller goods.

    Machine strech film

    Machine strech film

    Machine stretch film is strong, versatile, durable and highly resistant which is specially used for high volume goods. They have the unique capability of providing high strength and puncture resistant load retention needed to protect vulnerable goods.

    Machine stretch film is further categorized into following types

    • Blown stretch film: this film is made by the process of blown extrusion in which resins are heated and blown into a bubble which in turn is converted into a sheet that is rolled and applied to a core tube.
    • Cast stretch film: this film is made by the process of cast stretch in which resins are heated and fed through a series of cooled rollers which then solidifies the film.
    • Pre-stretched film: this film, as the name suggests is already stretched before it is used, that is, during the manufacturing process.

    6.What Types Of Equipment Is Used To Apply Shrink Film?

    The following equipments are used to apply shrink film

    Automatic side sealers

    Automatic Side Sealers

    This equipment is high speed which uses continuous motion to wrap the product. It does this with the help of a mechanical arm which trims and clings the film around the product. Due to its high speed, it is an excellent choice to use it in industries which need to wrap thousands of products in a single day.

    Shrink tunnels

    Shrink Tunnels

    Shrink tunnels use a certain temperature to further shrink the film which has already been tightly adhered with the help of a shrink wrap machine. It comes in single and dual chamber format in which the dual chamber has the ability to package goods at a faster rate.

    Shrink bundling machine

    Shrink Wrapping VS Stretch Wrapping

    Packaging of your laboursomely produced goods is somehow difficult task when it comes to retain their quality, appearance and structure by keeping them well organized especially during transit because improper packaging can ruin your products.

    Thus to counter this obstacle, the packaging industry is constantly striving to introduce best technology for solving it which eventually results in presenting the two distinct but essential ways of packaging, namely; shrink wrapping and stretch wrapping.

    However, these both have certain qualities in their respective structural and functional spheres. What are these? Can be perfectly understood by thoroughly examining the article explained below!

      Add a header to begin generating the table of contents

      1.What Is Shrink Wrapping?

      Shrink Wrapping

      Shrink wrapping refers to the packaging of goods by covering them loosely with plastic film so that it can be shrinked after getting heat. In this type of packaging, heat is applied and it works as a main source for the purpose of tightening film around the products.

      Shrink wrapping not only pack the bulk products rather it is the most popular way of primary packaging for enormous goods that’s why it is an essential packaging equipment every manufacturer looks for. There are various machines utilized for shrink wrapping. All of them are designed with particular characteristics.

      2.What Is Stretch Wrapping?

      Stretch Wrapping

      Stretch Wrapping can be defined as the way of packaging in which large number of cartons are tightly joined together by flexible plastic film through stretching. This type of packaging is performed by special machines known as stretch wrapping machines.

      Unlike shrink wrapping machines, they do not use heat for wrapping instead the constant movement of turntable leads to the hermetic packaging. In addition, need for stretch wrapping becomes inevitable when it comes to transportation of large volume commodities.

      3.Whose Structure Is More Complex Between Shrink Wrapping Vs Stretch Wrapping?

      • Components

      The structure of shrink wrapping machine and stretch wrapping machine is totally different which can be analyzed by looking into their components:

      Shrink Wrapping

      Shrink Wrapping-1

      Shrink wrapping machine is highly complex integrated with so many parts. They are:

      Control Panel

      Control panel is the key component of shrink wrapping machine through which you would be able to communicate your commands into it. It mainly comprised of conveyor belt speed along with separate system for temperature control due to integrated heat system.

      Conveyor Belt

      Another element which works as a road for all your goods to pass through the shrinking phase is conveyor belt. Increasing its speed is used when your products require less heat while it is decelerated when nature of plastic used is hard to get shrinked.

      Conveyor Motor

      Conveyor motor is usually located beneath the conveyor belt and indicates its speed when alteration is done via control panel.

      Heating System

      The core part of any shrink wrapping is obviously the heating source which can be found in so many forms like that of heater bank, steam tubes or electromagnetic force. This heat source shrinks the surrounding film of products.

       Tunnel

      Most of the fully automatic and semi automatic shrink wrapping machines have enclosed area which is called shrink tunnel. Heating system is fitted here, products come out in final shrink form when passed through this area.

      Curtains

      Silicone coated polytetra fluoroethylene curtains are hanged outside both the openings of shrink tunnel for reducing heat loss.

      Film Rollers

      An essential component of shrink wrapping is film rollers which are fixed in particular areas of machines for dispensing over the products.

      Stretch Wrapping

      Stretch Wrapping-2

      Structure of stretch wrapping machine is quite simple with few parts. These are:

      Lifting Track

      Lifting track can be also referred as tower which works as a tall stand having separate space for control panel and film frame.

      Film Frame

      It is situated in the lifting track in such a way that it easily moves towards upward and downward direction while dispensing the film which is placed inside the frame.

      Turntable

      It is the place where bulk containers are placed in arrange form. The circulatory movement of turntable is the main step when cartons get wrapped collectively.

      Control System

      Like other machines, stretch wrapping also has proper controlling system but unlike shrink wrapping, here the speed of turntable and direction of film frame is adjusted.

      Cut-Clamp-Brush Mechanism

      These are two parts which combinely named as cut clamp brush. Clamp is a metal device located on table that holds the film so it can be stretched around load. Cutter and brush are carried out by the frame which comes into action when process becomes completed, cutter cuts the film and brush stick the film end on load.

      • Auxiliary Devices

      Auxiliary devices are that equipment which are not necessary for running the process shrink wrapping or stretch wrapping but they add into the existing efficiency of machine.

      Shrink Wrapping

      Supportive equipment for shrink wrapping are more in number than stretch wrapping. They are:

      • Liquid filling machine
      • Bottle inspection machine
      • Shrink sleeve labeling machine
      • Bottle capping machine
      • Induction sealing machine

      Stretch Wrapping

      Contrary to shrink wrapping, stretch wrapping mechanism is done by single machine and there is no such need for additional accessories. However, few are described below:

      • Conveyor belt
      • Pallet weighing system
      • Low profile access ramp

      4.Differentiate Between Shrink Wrapping And Stretch Wrapping?

      • Material Used

      Shrink Wrapping

      Shrink Wrapping-2

      Films used for shrink wrapping are often hard and rigid in nature eventually do not possess flexibility. They are mostly made up of polyvinyl chloride and polyolefin. The reason behind to choose such type of films is to fully assure that products are covered with firm protective plastic so that external elements would not damage inner quality of materials.

      Stretch Wrapping

      Stretch Wrapping-3

      As a matter of fact, stretch wrapping film is the result of lean stretchable plastic usually prepared from polyethylene plastic. It contains high degree of elasticity and has the ability to expend its existing length up to 300%. That’s why; regardless of the extreme pressure it shows flexibility and is split-resistant.

      • Working Process

      Shrink Wrapping

      Shrink Wrapping Working Process

      Working process of shrink wrapping is little bit convoluted to understand and has to be performed by certain fixed steps such as:

      Initially, the machine provides you with an integrated set of graphics in form of control panel and let you enable to set parameters according to your requirements. Once you are done with this step, there is no need to bother in form of manual intervention.

      Machine will take the commands and dispense dual layers of transparent or printed film to loosely but completely cover the bulk products. In case of individual item film is delivered as per desired like half, full or neck sleeve etc.

      These items are then passed through heating phase mostly under heating tunnel where film around them get shrinked and adopt the shape of objects.

      Stretch Wrapping

      Stretch Wrapping Working Process

      Process of stretch wrapping is extremely easy that any layman can understand it and consequently operate without any need for experts. Its mechanism of action is given below in few steps:

      The machine can be executed by simply loading material over turntable in sequence. Switch is turned on, and machine follows the directives set in control panel.

      Stretchable plastic film is held by clamp after which the motion of table starts in rotary form. Film is constantly released by roller and tightly binds around the bundle.

      Once bundle gets wrapped, cutter cuts down the film end and brush press the film so that it would properly attached to the load. The operation gets finished here.

      • Classification

      Both shrink wrapping and stretch wrapping can be divided into the types of ways they are done. However, all of them vary from one type of wrapping method to another type of wrapping. Below table clearly demonstrates the real picture of these differences like:

      No Types Shrink Wrapping Stretch Wrapping
      1 Fully Automatic Fully automatic shrink wrapping is done independently by machine where load is conveyed through conveyor belt, covered with plastic and passed through heating phase. Here load is delivered by guiding rail on turntable whose consistent rotation leads the flexible plastic to surround the bundle tightly.
      2 Semi Automatic Objects are manually placed by operator and rest process is achieved by machine itself. Cartons are placed in arrange form over turning table and machine then do its operation automatically.
      3 Manual Here a heat gun is used with hands which exhale heat to get the plastic over objects shrinked around them. While as, in stretch wrapping manual means that operator just take the roll of stretchable film and starts surrounding the load with it. There is no machine present here.

        Add a header to begin generating the table of contents

        1.What Is An Automatic Shrink Wrap Machine?

        Automatic Shrink Wrap Machine-1

        An automatic shrink wrap machine is a device used to package products using plastic film. It typically involves the automatic feeding of the product into the wrapping area, followed by automatic sealing and cutting of the film around it.

        The heat from an external heating element causes the material to shrink tightly around the product providing secure packaging that also helps protect against moisture, dust, and tampering.

        Also, this machine is ideal for high-volume production and efficiency. It can be configured to work with various materials such as PVC, polyethylene (PE), polypropylene (PP), and more. It also saves production costs by a great percentage.

        2.How Does An Automatic Shrink Wrap Machine Work?

        Automatic Shrink Wrap Machine-2

        Automatic Shrink wrap machine works by automatically feeding the pre-cut film into the chamber before it is heated and sealed. The machine will then move the product on a conveyor belt, allowing it to pass through the heated chamber.

        Once inside, the shrinking tunnel uses infrared heaters to shrink the film around the product and seal it. Then, the conveyor belt movement ensures that each product is evenly wrapped and sealed with minimal assistance from human operators.

        3.What Are The Working Principles of An Automatic Shrink Wrap Machine?

        Automatic Shrink Wrap Machine-3

        Automatic and manual feeding modes. In automatic mode, this device can automatically package items quickly and efficiently with pre-programmed settings and operators can manually adjust the parameters for each item as required in manual mode. These modes provide flexibility and make automatic shrink-wrap machines more efficient.

        This machine uses a combination of heat and shrink-wrap film which activates when it detects an item passing through the internal chamber to package items. This heats the shrink-wrap film causing it to form a tight seal around the item. Once sealed, the automatic shrink wrap machine then cools the film, which shrinks it tightly around the item.

        4. Which Kind Of Foodstuffs Can Be Packed By An Automatic Shrink Wrap Machine?

        Automatic shrink-wrap machines are a great choice for food product packaging. This equipment can be used to package different types of foodstuffs such as vegetables, fruits, meat, fish and prepared meals.

        Vegetables

            • External parameters involved in the process including power supply, device maintenance, cleaning, gun heat temperature and pressure checked and set to standard value.
            • Manually film reel is stretched onto the surface of the product and is properly wrapped with it. Heat at standard temperature is applied to shrink the film on the product surface.

            b. Semi-Automatic Shrink Wrap Machine

            Semi-Automatic-Shrink-Wrap-Machine

            Semi-automatic shrink wrap machines follow an intermediate working principle as compared to both manual and fully automatic machines.

            • Initially all external parameters including power supply; device maintenance, cleaning, heat and conveyor speed are set to standard.
            • The product is fed by the operator onto the moving rollers and sent to the system. Manually wrapping of shrink film is done and then proceeded to the system.

            c. Automatic Shrink Wrap Machine

            Automatic-Shrink-Wrap-Machine

            •  Like manual shrink wrap machine, all the external parameters including power supply, device maintenance, cleaning, heat, and conveyor speed are set to standard.
            • As the parameters are set, the process of product feed takes place. The product is placed on the conveyor belt or rollers and then it enters the film dispensing area.
            • Here the film is wrapped on the product automatically. As the wrapping gets completed, the product enters a controller chamber where heat is applied to it and the process of shrinking is carried out.

            5. What Are the Main Components of a Shrink Wrap Machine?

            While working on a shrink wrap machine, a few components play their important part are:

            Components present in different types of shrink wrap machine

            S.NO Components Manual Shrink Wrap Machine Semi-Automatic Shrink Wrap Machine Automatic Shrink Wrap Machine
            1 Power Supply yes yes yes
            2 Controlling and Monitoring Panel no yes yes
            3 Film Roll yes yes yes
            4 Heating Chamber no yes yes
            5 Heating Gun yes no no

            9 Rollers no yes no
            10 Transit Unit no yes yes
            11 Conveyor no no yes

            Some of the common components in all types of shrink wrap machines are:

            • Power Supply Unit

            Power-Supply-Unit

            A power supply is present in each shrink wrap machine either manual or automatic. This is the main component of a shrink wrap machine that is used to operate the machine is the power supply unit. In some machines, the power supply unit supports input power from 24V to 440V which makes it reliable to use in any part of the world.

            • Controlling and Monitoring Panel

            Controlling and Monitoring Panel

            The controlling panel is mostly present in an automatic shrink wrap machine as in a manual system all the parameters are controlled and monitored by the operator himself. Parameters, activities and controlling of a shrink wrap machine are done through this control panel.

            A control panel contains push buttons, variables, switches, fuses and potentiometer that are used to control the activities in shrink wrap machine. Conveyor speed and heating temperature is also changed from this control panel.

            • Silicon Strip

            Silicon-Strip

            A silicone strip is used to seal wires present in a shrink wrap machine due to its continuous contact with the machine’s body. This strip is important because the up-and-down movement of the sealing bar can cause trouble to the wires.

            Machine and material safety can also be ensured by applying silicon strips.

            • Micro Knife

            Micro-Knife

            Manually the operator cut the excess material but in an automatic machine, it is done using a micro knife. As the shrink film gets wrapped on the product the excess film is cut using this micro knife.

            It is used in places where high-output procedures take place in cutting time. Rather than cutting through ordinary knives or blades, this method is highly sustainable and quick. Thousands of products can be sealed using a single micro knife.

            • Conveyor Belts

            Conveyor-Belts

            Products in automatic shrink wrap machines enter the system through these conveyor belts or rollers. The speed, length and tension capacity of conveyor belts is decided according to the weight of the packaging material and its size.

            • Heating Unit

            Heating-Unit

            The heat tights the shrink material and holds the product tightly. The heat is produced by a heating present in a shrink wrap machine. It is important to control the heating temperature because it can damage the material if not properly applied.

            • Transit Channel

            Transit-Channel

            This is also present in an automatic shrink wrap machine as the transit channel is usually at the end of a shrink wrap tunnel which is commonly used to place the micro knives apart from both ends. The knife installed in a transit channel then cuts the excess film and reduces wastage.

            In addition to these components, there are several minor components like breakers, fuses, sealing bars and etc.

             6.What Materials Are Used for Wrapping in Shrink Wrap Machine?

            Wrapping-Materials

            Usually PVC, polyethylene and polypropylene films are used when it comes to the packaging of products using shrink wrap machines. The chemical composition of these materials provides them strength, quality, protection and reliability which is why they are ideal to be used for wrapping purposes.

            To provide sustainable wrapping of products and to keep the environment clean, some of the wraps that are considered in the modern world are

            • Compostable Material

            Compostable-Material

            Keeping the internal factors like temperature changes, humidity, atmospheric pressure and oxygen levels of industries, manufacturing plants and homes in view, researchers have created compostable shrink wrap that can overcome all these factors.

            The recycling process of shrink wrap gets separated from other options and protects the environment from being polluted

            • Recyclable Material

            Recyclable-Material

            Low-density polyethylene (LDPE) and Polyolefins are used as recyclable shrink wrap material due to their ability to be recycled easily. Industries collect all LPDE material from homes, industries and other places and recycle them in very less time.

            This type of shrink wrap is ideally used in hospital and pharmaceutical equipment wrapping.

            • Biodegradable Material

            Biodegradable-Material

            The most important factor while packaging through any type of material or machine is that it should have the ability to decompose harmful microorganisms. These microorganisms can waste food, medicine and other products and also can directly harm the human life associated with them.

            7. What Benefits Shrink Wrap Machine Provides?
