EVOH High Barrier Skin Film
Skin film is typically made from a flexible plastic material, such as polyethylene or polypropylene, that can conform tightly to the contours of the product being packaged.
The application of skin film in food packaging involves a process known as "skin packaging" or "vacuum skin packaging." In this process, the food product is placed on a tray or a base, and the skin film is tightly sealed around the product, conforming to its shape like a second skin. The film is usually heated to form a secure bond with the tray, creating a sealed and protective barrier.
The main purpose of using skin film in food packaging is to extend the shelf life of the product by providing a barrier against oxygen, moisture, and external contaminants. The film adheres closely to the product, preventing air from coming into contact with the food, which helps to maintain freshness and reduce the risk of spoilage. It also provides a transparent display, allowing consumers to see the product clearly.
Skin film is commonly used for packaging a variety of food products, including fresh meats, poultry, seafood, fruits, vegetables, cheese, and processed food items. It is particularly beneficial for products with irregular shapes or those that have sharp edges, as the conforming nature of the film helps to secure and protect such items effectively.
Moreover, skin film is suitable for various retail environments, as it enhances the visual appeal of the packaged product, providing a clear and glossy presentation. It is also compatible with modified atmosphere packaging (MAP), allowing the adjustment of the gas composition inside the package to further extend the shelf life of the food product.
Overall, skin film is a versatile and effective packaging solution for preserving the quality and appearance of food products, while also offering convenience and protection to both manufacturers and consumers.
