Pack fromage en aluminium exigences de qualité de papier d'aluminium

Aluminium une feuille d'emballage du fromage is widely used in cheese packaging because of its high reflectivity to heat and light, bonne isolation, une forte protection, l'imperméabilité aux gaz et à la vapeur d'eau, ce qui peut empêcher le fromage de la noyade et la gazéification, et ne sont pas exposés à des bactéries et des insectes. Le fromage est une sorte de produits laitiers à forte valeur nutritionnelle, it has its own unique characteristics, such as size, façonner, Couleur, ripening conditions, flavor, enrobage, surface mildew, which put forward high requirements for cheese packaging material, not only to ensure the quality of different cheese, but also to extend shelf life as long as possible.

The packaging of cheese products seriously affects the performance, cheese packaging foil materials should not contain harmful ingredients to ensure food safety. Cheese packaging foil materials also require processing characteristics and gas barrier properties to meet the needs of the product. Processing characteristics include thermoformability, thermoscellabilité, mechanical stability, hot stretchability, machine walkability, and ecological and economic constraints. Gas barrier is mainly to prevent the penetration of oxygen, carbon dioxide, nitrogen and water vapor. Usually aluminum cheese packaging foil materials first require blocking oxygen to prevent mold growth. Deuxièmement, some mature cheeses pack foil are required to block the water vapor in order to avoid water loss and cause quality loss.
