Medicines, drugs and sometimes liquid syrups are fill in bags made up of plastic, film or polythene and then sealed using a foot operated heat sealer. There is a wide use of heat sealers in a Pharmaceutical industry and mostly foot sealers are used due to their better productivity and easy handling

4.What Is The Working Principle Of A Foot Operated Heat Sealer?

Working Principle of a Foot Operated Heat Sealer

A foot operated heat sealer has a simple operation. It follows following steps.

• Initially, the parameters like temperature, heating cycle and speed of foot operated heat sealer are set to standard or according to the material on which sealing is carried out.
• As the parameters are ensured, bags or pouches of different materials are kept on the bottom jaw of a foot operated heat sealer.
• Afterwards the operated pushes down the pedal, both the jaws get in contact and sealing is done due to heat bonding of both jaws.
• As a result of this heating, the material melts and proper sealing is carried out.
• When the cycle is completed, an alarm indicated the finishing of process and the operator removes its foot from the pedal. Both the jaws get separated and the finished product is taken out of the foot operated heat sealer.

5.What Types Of A Foot Operated Heat Sealer Are Available In Market?

Types of a Foot Operated Heat Sealer

There are three types of foot operated hand sealers

Double Sided Foot Operated Heat Sealer

A double-sided foot operated heat sealer is compatible with almost every type of material. As the foot pedal gets activated by the operated, both top and bottom side gets in contact in this type of foot operated heat sealer. This ensures sealing of wide range of materials including vinyl which was difficult to seal in earlier times. A seal width of 5mm can be achieved in a double sided foot operated sealer.

Single Sided Foot Operated Heat Sealer

This type of foot operated heat sealer is the most efficient one used in packaging of variety of packages. They are used for packaging of small pouches to heavy materials with a thickness of 6 to 10 mm. Hands free operation is carried out in a foot operated heat sealer and allows a seal width of 5mm.

Constantly Hot Foot Operated Heat Sealer

Industries where processes are carried out every time use constantly hot foot operated heat sealer. These machines allow quick sealing of products with strong hermetic sealing.   A constantly hot foot operated heat sealer allows more sealing width as compare to the rest two which is around 5 to 10 mm.

6.What Material Is Used To Seal In A Foot Operated Heat Sealer?

Sealing Materials in a Foot Operated Heat Sealer

Foot operated heat sealers are widely used to seal materials like plastic, aluminum foil and polypropylene. However sometimes paper bags are also used in industries for packaging of products. The specification of these materials according to their sizes are

Plastic Bag

One of the most commonly used material for packaging purpose is plastic or polythene. They are highly recommended due to the versatile behavior of carbon and hydrogen bonding which makes it very hard to break. A foot operated heat sealer also seals a plastic bag which ranges between 5 to 10mm depending upon the temperature set for sealing.

Aluminum Foil

After plastic bags, aluminum foils come second in terms of packaging purpose. Mostly food and agricultural products are packed in these types of materials to keep them safe. An aluminum foil of 10 to 15mm can be easily sealed using a foot operated heat sealer.

Plastic / Polypropylene Sealing

With more than 20 mm of thickness, polypropylene bags are the thickest ones which are sealed using a foot operated heat sealer. They require high temperature for their sealing as their melting point cannot be achieved at low temperature

7.What Is The Difference Between A Foot Operated Heat Sealer And An Ordinary Heat Sealer?

Foot Operated Heat Sealer and Ordinary Heat Sealer

Following is the difference between a foot operated heat sealer and an ordinary or traditional heat sealer.

S.NO	FACTOR	FOOT OPERATED HEAT SEALER	ORDINARY HEAT SEALER
1	Pressure	Foot operated heat sealer is set on a certain pressure value which remains same throughout the cycle. This results in identical sealing on all the products	While in a traditional sealer the pressure varies in each cycle depending upon the operator’s ability. As a result, the product shows different sealing width in each cycle.
2	Sealing Quality	High quality sealing is achieved in a foot operated heat sealer.	Poor quality sealing can be done manually and a lot of wastage can occur.
3	Wide Range	A foot operated heat sealer offers wide range of material compatibility and can be set according to the width of bag.	Single machine only shows compatibility to limited material width. The manufacturer has to buy separate machine for all products.
4	Economical	Foot operated heat sealer is economical in a sense that only one-time investment is carried out and life time benefit can be taken.	A lot of investment is required if different materials with different thickness and width are to be processed
5	Productivity	Higher productivity can be achieved.	The machine depends upon the ability of its operator
6	Edge Cutting	Knives are present in machine to cut the bag after sealing process.	Manually cutting of edges is done which sometimes shows improper cutting.

8.What Are the Main Components In A Foot Operated Heat Sealer?

Main Components of a Foot Operated Heat Sealer

The main components of a foot operated heat sealer are

Jaws

The most important part of a foot operated heat sealer are the top and bottom jaws. These are responsible for sealing of products. The product is placed in between of these jaws and during operation both these jaws get in contact which in result seal the material

Heating Element

The temperature is maintained at the heating elements of a foot operated heat sealer. These are on the jaws of machine and are responsible to melt the product with the produced heat

Pedal

Pedal is the most important part of a foot operated heat sealer as it is responsible for the operation of machine. The operator pushes the pedal downwards and as a result an electrical signal is transferred to joint both the jaws. When the foot is removed from the pedal the jaws get separated. Pedals basically converts a mechanical signal to electrical one

Control Panel

The operation of a foot operated heat sealer is controlled through this control panel. All the knobs and buttons like power, temperature control, regulator, switched all are present in the control panel and an operator directly gets involved with it

Transformer

A transformer basically controls the over and low voltage of a foot operated heat sealer and maintains the power throughout its operation

9.What Common Errors Are Found In A Foot Operated Heat Sealer?

Common Faults in a Foot Operated Heat Sealer

S.NO	PROBLEM	CAUSE	TROUBLESHOOTING
1	Poor Sealing	Incorrect sealer temperature	The most important factor of poor sealing is insufficient temperature. The temperature should be checked properly before starting of packaging.
2		Excessive pressure	Reduce the pressure by the pressure knob present on the control panel.
3		Insufficient pressure	Increase the pressure by the pressure knob present on the control panel.
4		Insufficient sealing width	Check both the top and bottom jaw of the machine and its sealing width according to the width of material.
5		Misalignment of jaws	Check both the jaws and align them accordingly
6	Poor Cutting	Improper adjustment of anvil	Adjust both the cutting knife and the anvil
7		Difference in jaw temperature	Check temperature of both jaws of a foot operated heat sealer and adjust it according to the requirement
8		Improper cleaning of jaws	Cleaning the jaws properly before start of production.
9	Open Ended Seal	Sticking of film on jaws	Check temperature of both jaws and adjust it according to the requirement
