As a key element to ensure food safety and extend shelf life, food packaging film has many significant characteristics. These characteristics not only meet the basic needs of food packaging, but also improve the quality of food and the purchasing experience of consumers.
Heat resistance
With the continuous improvement of aseptic sterilization technology, heat-sealed packaging has become an increasingly popular packaging method. Food packaging film needs to have good high temperature resistance to ensure the stability and sealing of the packaging. This heat resistance not only helps to prevent food from being contaminated during processing and storage, but also extends the shelf life of food.
Transparency
Transparency is another important feature of food packaging film. Transparent packaging film allows consumers to clearly see the appearance and texture of the product, thereby increasing consumers’ trust in food and willingness to buy. At the same time, packaging film with good transparency can also help consumers feel the freshness and quality of food.
Moisture resistance
Moisture is one of the main causes of spoilage of many foods. Therefore, food packaging film must have good moisture and oxygen resistance to prevent food from becoming damp or deteriorating. Moisture resistance can not only keep food dry and fresh, but also extend the shelf life of food.
Plasticity
Food packaging film needs to have sufficient plasticity and deformation properties to adapt to foods of different shapes and specifications. This plasticity helps to maintain the beauty and tightness of the packaging, while making it convenient for consumers to use and store food.
Application of Label film and Packaging film
In the field of food packaging, Label film and Packaging film play an important role. Label film is used to stick on food packaging to provide important information such as product information, production date, and shelf life. Packaging film is directly used for food packaging to protect, store and transport food. These two film materials together constitute an important part of food packaging and ensure the safety and quality of food.
Application of Thermal transfer film in food packaging
Thermal transfer imaging technology is also used in the field of food packaging, among which Thermal transfer film is used to print and transfer text, patterns and other information on food packaging. This technology not only improves the visual effect of packaging, but also can realize personalized customization and anti-counterfeiting functions, adding new value to food packaging.
