Advantages and applications of high barrier stretch film

High-barrier technology is the emergence of the packaging industry based on the market's requirements for consumers. Aluminum-plastic vacuum bags are used to solve consumers' requirements for fresher food products on the market, and to maintain the original flavor and high quality of the products. After years of development, many packaging products have been born from high barrier technology, such as barrier packaging materials such as high barrier stretch films. Heat shrinkable film

Barrier packaging materials have been used in the packaging industry for a long time. Products are packaged with materials that can block oxygen and water vapor penetration to achieve the purpose of extending the shelf life and shelf life of food, medicine, cosmetics and environmentally sensitive items . The high-barrier stretch film is a multi-layer structure co-extruded film made by simultaneously extruding a material with strong gas barrier properties and a polyolefin with strong thermal seam and moisture barrier properties.

The application of high-barrier stretch film enables the products in the package to maintain freshness, taste, quality, safety and hygiene during storage, transportation and commodity distribution. Therefore, high-barrier stretch film can be widely used in the food packaging industry, and There are many applications of high barrier stretch film in cosmetics, petroleum, chemical, pesticide and many other industries.

In the high barrier stretch film, there are several kinds of EVOH five-layer co-extruded film and PVDC coated film. Among them, the EVOH five-layer co-extruded film has barrier properties, antistatic properties, good oil resistance, organic solvent resistance, and can be recycled, burns without pollution, is safe and environmentally friendly, and has transparency, gloss, mechanical strength, and elasticity. Resistance, abrasion resistance, cold resistance and surface strength are all excellent; while the PVDC coating film has good oxygen and water barrier properties at the same time, the coating can be heat-sealed, and its production cost is relatively low, and it has existing applications in the market It is used in food vacuum packaging and also in pharmaceutical packaging.
