Summary
Easy Peel Film Manufacturer's View Food stretch film has self-adhesive properties and is a single-sided (cast) or double-sided (blown) plastic film with adhesive, which can tightly wrap the items being packaged. The self-adhesiveness does not stick to the surface of the food being wrapped but only exists between the film and the film surface. No heat shrink treatment is required during packaging, which helps save energy, reduce packaging costs, facilitate container transportation, and improve logistics efficiency. Generally, food stretch film should have the following characteristics:
1. High Barrier: Easy Peel Film Manufacturer's View Utilizes different plastic materials and various co-extruded films with different barrier properties to achieve high barrier effects against oxygen, water, carbon dioxide, and odors;
2. Strong Functionality: Oil-resistant, moisture-resistant, resistant to 120°C high-temperature cooking, resistant to low-temperature freezing, maintaining quality, freshness, and odor. Suitable for vacuum packaging, aseptic packaging, and gas-flushed packaging;
3. Low Cost: Easy Peel Film Manufacturer's View Compared with other plastic packaging, glass packaging, and aluminum foil packaging, co-extruded films have cost advantages while achieving the same barrier effect. Due to simple processing, the production cost is 10-20% lower than dry composite films and other composite films. 10-20%.
4. Flexible Structural Design: Different structural designs can be adopted to meet the quality requirements of different products;
5. High Strength: Easy Peel Film Manufacturer's View Co-extruded films have stretching characteristics during processing. After stretching, the strength of the plastic can be correspondingly increased. Nylon and metallocene polyethylene materials can be added in the middle to provide composite strength higher than ordinary plastic packaging, without delamination, good flexibility, and excellent heat sealing performance.
6. Small Volume Ratio: Easy Peel Film Manufacturer's View Co-extruded films can be vacuum shrink-wrapped, with a volume ratio close to 100%, which is incomparable to glass, tin cans, or paper packaging.
7. No Pollution: No adhesive added, no residual solvent pollution issues, environmentally friendly.
Easy Peel Film Manufacturer's View Stretch film is made from polyethylene terephthalate (PET) raw material, produced by extrusion into sheets, then biaxially stretched to form a stretch film material. It is a colorless, transparent, glossy stretch film with excellent mechanical properties, high rigidity, hardness and toughness, puncture resistance, abrasion resistance, high and low temperature resistance. It has good chemical resistance, oil resistance, gas tightness, and fragrance retention, and is one of the common substrates for barrier composite stretch films. However, polyester stretch film is relatively expensive, generally with a thickness of 12m, often used as the outer layer material for cooking packaging, with good printability.
Easy Peel Film Manufacturer's View Stretch polyester film is commonly used in convenience foods, beverage markets, electronics and electrical appliances, and metal products, especially shrink labels, which are its main application areas. With the rapid development of PET beverage bottles, cola, Sprite, various juice bottles all require PET heat shrink film as matching heat seal labels. They belong to polyester materials, are environmentally friendly, and easy to recycle.
