Sealing a trays guide


The food and beverage sector is aware of the importance of packaging in keeping food fresh, facilitating transportation, and enticing consumers. However, with so many food packaging alternatives on the market, it is easy to become lost in the language and diversity of possibilities.

Don’t worry, it’ll all work out. With this comprehensive guide to Food Tray Sealing Machine, we’re here to take the guesswork out of the process for you.

Tray Sealers: What Are They?

Thermal sealers, tray lidding machines, and top sealers are all terms for the same thing: machines that attach plastic film lids to various trays of various materials. That’s what makes it the best option for anything from industrial fasteners to fresh vegetables to meat to frozen dinners to ready-to-eat meals.

What Is the Process of Using a Tray Sealer?

The product-filled trays are indexed and spaced as they enter the in-feed conveyor. A transfer beam then picks them up and transfers them to the tooling. The product-filled trays are then lifted by the seal plate and pressed against the film. The sealing characteristics against the tray are activated by compressing the film and trays against the heated top tooling, while the film is cut at the same time. Upon completion of the seal dwell period, the seal station returns to its original position and the trays are ejected from the machine.

Tray Sealing has several advantages.

Reduce the Use of Plastic:

Up to 25% less material is used in making conventional clamshell packaging when using top seal.

Extra Longevity:

Food spoiling may be prevented by using a top seal film to shield items from temperature fluctuations. As a result, less food is wasted and less food is consumed.

Improved Productivity:

Packaging has a significant role in the purchasing choices of half of consumers, according to research. Because of this, the option to personalise trays and tray film gives a chance to improve branding and build brand loyalty.

Enhancing Product Security:

Food safety is improved by tray sealing because it creates an airtight seal that prevents dirt and moisture from entering the container, which reduces contamination risk. Consumers can see through tamper-evident film whether a seal has been broken.

Enhanced Adaptability:

A wide range of tray sealing machines are available that can accommodate a variety of tray sizes and can be combined with other parts of the manufacturing line.

Downtime is minimised.

Interchangeable components and a programmable interface allow the tooling to be changed in less than two minutes. It is possible for Crawford’s Service Team to diagnose and resolve difficulties remotely through the internet.

Perspective on production:

Web-based view of the machine and its present working status, live production data, historical records of stoppages, and changes to the machine settings are all provided through this service.
