The heat sealable aluminum trays have numerous advantages for both industrial operators and consumers. In particular, they simplify the preparation process of the food destined for sale. To better understand this statement, let’s analyze the various steps: once the food has been prepared, it can be cooked and then blast chilled in the container. Then, according to need, the operator can choose to carry out the heat sealing on the counter, or to package the product in MAP (Modified Atmosphere Packaging), if intended to be consumed in the medium-long term. MAP is a technology permitting the easy modification of the composition of the gases present in the packages. The main purpose of this packaging process is to extend the preservation of the quality of foodstuffs. After that, once the consumer has purchased a previously heat-sealed aluminum tray, he can heat it at home, in the traditional or microwave oven, and enjoy the food in complete safety.
