Food thermosealing is a method of closing trays by applying pressure and heat to a plastic film using a manual, semi-automatic or automatic tray sealer such as those produced by AK RAMON. It is also known as heat sealing and serves to isolate the products stored in the container from air and other external agents such as bacteria and microbes.
The main characteristics of a good manual tray sealer are that it can be adapted to all types of heat sealable containers and guarantees rapid heating of the Teflon plate thanks to a power that must be at least 900 W to reach 230º C.
There are many advantages to using heat sealing for food preservation:
It offers a more attractive and hygienic presentation of the food for the consumer.
Heat-sealing allows food to be kept in excellent condition, preventing it from being crushed.
The use of heat-sealing facilitates the storage of food in suitable plastic containers or heat-sealable trays.
It allows large quantities of food to be packaged in short periods of time.
It can be used in any type of business such as butchers, fishmongers, delicatessens, fruit shops, supermarkets, catering companies, take away and restaurants.
