What is the difference between POF shrink film and polyvinyl chloride shrink film?

POF five-layer co-extruded heat shrinkable film is a new generation product that has gradually emerged in recent years and has been accepted by people. The environmentally-friendly multi-layer co-extruded polyene fused POF heat shrinkable film uses linear low-density polyethylene (LLDPE) as the middle layer and co-polypropylene (PP) as the inner and outer layers in a special equipment. , The outer three layers are co-extruded to produce a heat shrinkable film with high transparency, high shrinkage and good heat sealing performance. It has all the advantages and advantages of polyethylene (PE) and polypropylene (PP) at the same time, and its excellent performance is far superior to pure polyethylene (PE) film and polypropylene (PP) film. Environmentally friendly heat-shrinkable packaging materials that are widely promoted and used in the European and American markets.

It complies with the US FDA and USDA standards and is made of environmentally friendly materials. It is an environmentally friendly packaging material that can be recycled and reused. Especially suitable for the pharmaceutical industry and the food industry. Products comply with “GMP” requirements.

PVC heat shrinkable film is made of ethylene PVC resin mixed with more than ten kinds of auxiliary materials and then inflated twice. It is characterized by good transparency, easy shrinkage, high strength, and the shrinkage rate can be adjusted freely according to user needs.

Features are as follows:

PVC shrink film has the characteristics of high transparency, good gloss and high shrinkage.

POF shrink film has high surface gloss, good toughness, high tear strength, uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film.

POF film is a transparent and glossy packaging film that closely adheres to the appearance of the product. Its characteristics of energy saving, environmental protection, high shrinkage, transparent gloss, and strong tear resistance overturn the limitations of traditional packaging films, and are well received by the market. Welcome, much loved by consumers. POF film is suitable for a variety of packaging fields, including packaging in food, daily necessities, cosmetics and other fields.


The advantages of POF film can be summarized as the following 5 points, which are:

1. Strength and toughness: obvious sealing, good shrinkage, tight molecular structure.

2. High transparency: no pattern, no crystal points, high gloss and transparency.

3. Uniform thickness: The sealing temperature is between 200-290℃ and the thickness is uniform.

4. High shrinkage rate: POF film has a very high shrinkage rate, so it is suitable for product packaging of various shapes.

5. Strong cold resistance: POF film can maintain flexibility even at minus 20 degrees, and the product shrinks perfectly.

POF heat shrinkable film is a kind of packaging film with transparent gloss, high shrinkage, environmental protection and safety, and strong tear resistance. During the production process, it is stretched into various shapes regardless of the stretching orientation, so as to adapt to various shapes. Product packaging, POF shrink film packaging is tightly attached to the surface of the product, forming a transparent and sealed film on the surface, which is firmly wrapped around the periphery of the product, like a protective film.

POF heat shrinkable film technology was applied as early as the early 20th century, and then became popular all over the world. Nowadays, heat shrinkable film technology is almost used in various packaging fields, and its application fields are quite wide. POF heat shrinkable film technology It is currently the most environmentally friendly and safest and most popular packaging technology. Heat shrinkable film technology has experienced more than a century of changes and development. The technology has become more and more mature, and it continues to conform to the development trend of the times.

PVC heat shrinkable film is the earliest and the longest development history. Packaging film, however, with the development of the times and the rapid development of technology, PVC heat shrinkable film gradually runs counter to the world trend, so it is gradually eliminated by the market. POF heat shrinkable film is clean and environmentally friendly, and its practical and affordable fresh image gradually enters our field of vision. , And then replace the leading position of PVC heat shrinkable film in the packaging film market and become a mainstream packaging form.

In summary, POF heat shrinkable film technology is widely used in various packaging fields. In the rich and diverse packaging market, POF heat shrinkable film purifies our eyes and changes our living habits with its clean, environmentally friendly, practical and affordable fresh image .
