This type of packaging is used for wet products ready for human and pet consumption. This is done through a thermal process used for sterilization inside an autoclave machine that raises the pressure and temperature (up to 121°C / 250°F) to achieve its objective. Depending on the product, there is the option of material laminations so that the food, once the product is packaged, can be heated in a microwave oven for up to 90 seconds (only in laminations without Aluminum). These can be manufactured in 3 or 4 layers, depending on the need of the product.
