Abstract

Method for packaging food in a packaging container containing the wrap A package consisting of a core layer of paper or cardboard and an outer plastic coating layer of suitable polyethylene is low-density polyethylene. And operating with heat To food to extend its life on the shelves The package was packed and sealed. Transported through a laboratory or tunnel containing the heating area Where the container is wrapped It was heated to the desired operating temperature, for example 80-100 ํ C, where the container was retained. The wrap is maintained at the desired operating temperature during sufficient intervals to destroy, inhibit or eliminate unwanted microorganisms. And a cooling area where food is cooled Method according to this invention Both heating and maintaining the correct temperature Made effective by the liquid heating medium That's right, the water is hot at the same time. The packaged container received optimum external support pressures of less than 0.5 bar 0.2 and 0.3 bar during both of these operating states. To prevent deformation or other damage to the package container due to the expansion of the volume of trapped gas in the package.
