алюминий фольга для упаковки сыра is widely used in cheese packaging because of its high reflectivity to heat and light, хорошая изоляция, сильная защита, непроницаемость для газа и водяного пара, что может предотвратить сыр от утопления и газификации, и неуязвим для бактерий и насекомых. Сыр – это вид молочного продукта с высокой пищевой ценностью., it has its own unique characteristics, such as size, форма, цвет, ripening conditions, flavor, покрытие, 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, термосвариваемость, 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. во-вторых, some mature cheeses pack foil are required to block the water vapor in order to avoid water loss and cause quality loss.
