Bale film and plastic wrap film are cast films, which are non-stretching and non-directional flat-extruded films produced by melt casting quenching.
Bale film is used as a protective film for wrapping goods. It is hard and has poor transparency. It can only provide protection for goods, but cannot improve the beauty of goods.
POF shrinkable film according to the international standard carefully made small heat shrinkable packaging equipment, with simple operation, a wide range of application, good sealing, high transparency, low cost, high-grade characteristics, suitable for small and medium-sized batch products packaging.
Customers who use POF shrinkable film for the first time feel confused when they ask if they should have a hole punched in the film, and don't know whether to do it or not. Now I'm going to talk a little bit about perforating the POF shrinkable film.
POF heat shrinkable film is a new type of heat-shrinkable film material, which is made of linear low-density polyethylene as the middle layer (LLDPE), copolypropylene (PP) as the inner and outer layer, through three extruders, and then through die head forming, film bubble-blowing and other special processes. POF is environmentally friendly, high transparency, high shrinkage, good heat-sealing performance, high gloss, strong toughness, tear resistance, heat shrinkage uniform packaging film, suitable for automatic high-speed packaging, is the traditional packaging replacement products, widely used in audio and video products, tobacco, non-staple food, gifts, washing products and so on.
Beneficial for wrapping multi-packs of heavy items—for example, an outsized count of beverages or water bottles. it's highly durable and is in a position to stretch quite other films. like polyolefin, polyethylene is FDA approved for food contact.
POF is an abbreviation for polyolefin and generally refers to heat shrinkable shrink film.
Various machines are used POF shrink film, from simple heat guns to conveyor-driven heat shrink tunnels. The product, volumes, and purpose dictate the appropriate solution.
POF shrink bags are not suitable for heating in a microwave oven. Some colored plastic packaging especially cannot be placed in a microwave oven. After being added, these colors may fall off and release toxic substances, causing greater harm to the human body. Even the completely colorless POF heat-shrinkable bag is not suitable for microwave ovens, because plastic products are very likely to melt and release toxic substances that are more toxic and harmful. Food in POF heat shrinkable bags should not be kept cold in the refrigerator. Ordinary plastic packaging cannot achieve the preservation effect because it is not air-permeable. It will also cause bacteria to grow and endanger human health.
POF Heat shrink film is mainly used in the bundling and packaging of bottles, comparing the whole bundle of beer and pure water. With the progress of industrialization, the consumption of pure water is also increasing, and their development provides more opportunities for the application of heat shrink film.
Shrink film is used in the sales and transportation process of various products, the main role is to stabilize, cover and protect the items, shrink film is commonly used in outdoor, need to add anti-UV agent, so there are many types, there are PE shrink film, PVC shrink film, POF shrink film, etc., today and manufacturers together to see the difference between them
