Shrink Wrap are used in the sale and transportation of various products. Its main function is to stabilize, cover and protect the product. Shrinkage film must have high puncture resistance, good shrinkage and a certain shrinkage stress. During the shrinkage process, the film cannot create holes. Since shrink films are often suitable for outdoor use, UV anti-UV agents need to be added. Includes POF/PET/PVC/PP/PE shrink film.
(1)PE heat shrinkable film is widely used in wine, cans, mineral water, various beverages, cloth and other products of the whole package, the product has good flexibility, impact resistance, tear resistance, not easy to damage, not afraid of moisture, shrinkage rate;
(2)PVC film has the characteristics of high transparency, good gloss and high shrinkage;
(3)POF surface gloss, good toughness, tear strength, uniform thermal shrinkage and suitable for automatic high-speed packaging characteristics, is the replacement of traditional PVC heat shrink film. POF is the meaning of heat shrinkable film, the full name of POF multi-layer co-extruded polyolefin heat shrinkable film, it is linear low-density polyethylene as an intermediate layer (LLDPE), polypropylene (pp) as the inner and outer layers, through three extruders plasticized extrusion, and then through the die molding, film bubble blowing and other special processes.
(4)The characteristics of PET shrinkable polyester film: it is stable at room temperature, shrinks when heated (above the glass transition temperature), and more than 70% of the thermal shrinkage occurs in one direction. The advantages of shrinkable polyester film packaging are:1. transparent body, reflecting the image of the product. 2.Tight packaging, good dispersion resistance. 3.Rain, moisture, mildew proof. 4.no resilience, there is a certain anti-counterfeiting function. Shrinkable polyester film is often used in convenient food and beverage markets, electronic appliances, metal products, especially shrink labels is its most important application field. Because with the rapid development of PET beverage bottles, such as cola, Sprite, all kinds of juice and other beverage bottles need PET heat shrinkable film with it to make heat seal labels, they belong to polyester, is environmentally friendly materials, easy to recycle and reuse.
(5)PP(polypropylene) This kind of shrink film has high strength and toughness, good transparency, good protection function, and is very stable at low temperature or high temperature, and will not present problems such as fracture and crushing. Suitable for promotion, gift and collective sales packaging; And can print the name of the product, various patterns, etc., not only environmentally friendly and affordable, but also enhance the value of the product, but also in the promotion of the product portfolio, with gifts to do shrinkage, safe and delicate do not fall off, is an international popular commodity packaging materials.
In addition to being used as shrink labels, thermoshrinkable polyester film is now also being used on the outer packaging of daily goods. Because it can protect the packaging items from impact, rain, moisture, rust, and make the product win the user with a beautifully printed outer packaging, and it can well show the good image of the manufacturer. Nowadays, more and more packaging manufacturers use printed shrink film to replace the traditional transparent film.
