Characteristics And Use Of POF Shrinkage Film
- Jul 31, 2018 -

POF environment-friendly five layer co extruded polyolefin heat shrinkable film (POF shrink film, POF shrink film, POF heat shrinkable film)


POF heat shrinkable packaging film is a kind of multi-layer environment-friendly non-toxic heat shrinkable packaging material which is processed by co-extrusion blow molding process with PE and PP as main raw materials. In the early 1990s, it originated in Italy. The main features of the product are:


1, high transparency and gloss, can clearly show the appearance of products, improve the sales effect, and reflect the higher grade of goods.

2, good flexibility, easy to use. Because of this flexibility, the packed goods can be cushioned when subjected to external shocks. Packaging for brittle containers can also prevent the containers from breaking and flying away.

3. The contraction rate is large. The maximum shrinkage rate can be up to 75%. The contraction force produced by the high shrinkage rate can wrap a group of articles to be wrapped, and play a very good binding effect. It is very suitable for the collection of multiple items, especially for the packing of the special-shaped items. Moreover, the contractility of the po - C 3 film treated by a special process can be controlled to meet the requirements of different products for the shrinkage force.

4, welding sealing performance is good, high strength, suitable for manual, semi-automatic and high-speed automatic packaging.

5. It has good cold resistance and can be kept flexible at - 50 degrees Celsius without brittle cracking. It is suitable for packaging materials to be stored and transported in cold environment.

6, the environmental protection is nontoxic. The main raw materials of POF - C3 thermal shrinkable packaging film include LLDPE, TPP, PPC and necessary functional additives such as skid agent, anti adhesion agent, antistatic agent and so on. Package food in accordance with American PDA standard.

7, moisture-proof and dustproof.

8, the packaging cost is low, better than the carton and other materials packaging.

For the sale and transportation of various products, its main function is to stabilize, cover and protect products. The shrink film must have high puncture resistance, good shrinkage and certain shrinkage stress. In the process of contraction, the film does not produce holes. Because the shrink film is often applied to the outside, it is necessary to add UV UV resistant agent.

The use of thermal shrinkage.

Heat shrinkable film is widely used in food, medicine, disinfectant tableware, stylistic articles, craft gifts, printing products, hardware and plastic products, telephone, electronic appliances and other products, especially in the combination of irregular objects or goods (cluster) packaging, not only to meet the moisture, dust, dust, and protection of goods. With the function of touching and transparent display, it can also increase the attractiveness of the product, and can also be used to replace all kinds of cartons. It not only saves the packaging cost, but also conforms to the packaging trend. The shrinkable film (bag) can be processed into a flat bag, a circular arc bag, a trapezoid bag and a three-dimensional bag. The miniature heat shrinkable packaging equipment, which is made by the international standard, has the characteristics of simple operation, wide application, good sealing, high transparency, low cost and high grade. It is suitable for the packaging of small and medium quantity products. The heat shrinkable film machine and the sleeve marking machine are used together to form a set standard contraction machine line, which is widely used in the closed heat shrinkable packaging of drugs, food, drinks, cultural supplies, ceramics, daily chemical, soda, needle spinning and electronic audio and video products. It is a contractile machine for the rear package assembly line.
