1.What Is The Tray Sealer?
Tray sealer is a type of sealing machine that applies plastic films or lids on tray with precision and accuracy. No matter what the size, width or material of a tray is, the sealer is properly placed on that material to create vacuum and packaging material so that it can be kept safe from microbial attack.
Tray sealer is used in many industries because of its versatility. It offers more than one sealing options in a single machine and keeps the material fresh and safe. Ready to eat meals, frozen meals, meat, colors, and other products are sealed using these tray sealers.
2.What Are The Applications Of Tray Sealer?
A tray sealer is used in industries where products are meant to be kept contamination free and to secure from microorganisms present in atmosphere. Some of the applications of tray sealer are
Food and Packaging Industry
Mostly, food packaging industries use these tray sealers. It also makes the food look presentable and attractive for the customer. Food products like meat, vegetables, bakery items and others are sealed to safe them and to increase their shelf life.
Somehow pharmaceutical industry also uses these tray sealers for protection and packaging of instruments, equipment used in medical field.
Other industries like agriculture industry, confectionary industry and sports industry also uses tray sealer but on a very small scale to seal their products.
3.How Many Types Of Tray Sealers Are There?
There are two types of tray sealers available in global market.
Semi-Automatic Tray Sealer
In a semi-automatic tray sealer, an initial manual push is given to the tray by the operator. This pushed tray then enters in a rotational tray sealing station where further processes are carried out. Both manual and automatic processes are involved in this machine.
Industries where the production capacity is low, or they lie in medium size operation mostly use semi-automatic tray sealers. 30-50 trays can be sealed in a minute.
Fully Automatic Tray Sealer
On the contrary to semi-automatic tray sealer, a fully automatic tray sealer is operated completely on automatic operations. Trays are in-feed through conveyors and then enter the rotational sealing station. This reduces human efforts and cuts the operational cost.
Fully automatic tray sealers are so fast that they can seal around 150-200 trays/minute and that is the reason that they are most suitable for high production medium and large-scale industries.
4.What Are The Working Principle Of Tray Sealer?
A tray sealer also follows simple working principle like other sealing options. The steps involved in the procedure of a tray sealer are
- Initially all the parameters like temperature, pressure, film size and others of a tray sealer are checked and verified according to the standards.
- After that, the movement of conveyor and its speed is properly adjusted as per the production capacity. When all the external parameters are verified; the process of sealing starts.
- A tray filled with material is kept on the conveyor and from there it enters into the system. Here the tray gets its space and indexing accordingly.
- A transfer beam picks up the tray to transfer it further. As the tray reaches the system it is picked up by the seal plate which lifts the tray against the direction of film or lid. The tray is compressed by the upper heated tool which activates all sealing properties of it. The cutting of film is also done simultaneously.
- In the last step, when the seal is applied on the tray, the tray is lowered down back and transferred to the next cycle. The tray is then ejected from the sealer and the cycle completes here.
5.What Are The Components Of Tray Sealer?
Both semi-automatic and automatic tray sealers have common components to perform their proper function of sealing. A conveyor belt is additionally present in an automatic tray sealer to avoid manual feeding of products. Components responsible in performing sealing operation are

Temperature controllers are present on the control panels of a tray sealer. These controllers help in adjusting the temperature of sealing according to the material of film used. The operator can easily increase or decrease the temperature from this controller.
Film collectors are present on the top of tray sealers. There basic operation is to hold the film used for sealing and allow its proper movement into the machine.
Temperature, material, safety, and other parameters are directly monitored through these sensors. They play an important role in the operation of a tray sealer as they ensure proper sealing is done or not.
The movement of conveyor and the film rollers is done using these motors. Motors allow proper movement of material whether its tray or film so that proper sealing can be done.
Proper placement of trays in machines are done using these aluminum holders. They holder the tray and adjust it so that the seal can be applied on the specified space. These aluminum holders are adjustable and adjusted according to the size of tray.
It is present in an automatic tray sealer which is used to feed the product into the system without any human influence. The product also exits the system through these conveyor belts.
6.What Types Of Materials Is Used In Tray Sealer To Wrap Products?
Tray sealer requires highly efficient material for sealing purpose as it has to be stretched, expand and then heated. Materials due to their inherent properties should be reliable with all these factors. Some of materials used for sealing a tray are
Tyvek and PETG
When it comes to tray sealer, Tyvek and PETG (Polyethylene terephthalate glycol) are most ideal materials to be used for lid and tray respectively. Both materials are mostly used in medical industries as they are highly reliable for sterilization.
HDPE or High-density polyethylene is used as sealing material due to their compatibility of blocking vapors into the product. This material blocks the entry of atmospheric substances and provide greater vapor transmission rate. As a result, the product gets stable for a longer period.
PP or polypropylene is the most common material used for sealing purpose in all parts of the world. PP can be easily stretched to its maximum length and keeps the products secured from light rays. Product security during transportation and shipping can also be ideally achieved using a PP as sealing lid.
7.What Are The Advantages Of Tray Sealer?
