Difference between PVC heat shrinkable film and POF heat shrinkable film

by admin

1. Cost difference: POF proportion is 0.92, the thinnest thickness is 0.012mm, and the actual unit cost is low. The specific gravity of PVC is 1.4, the thinnest thickness is 0.02mm, and the actual unit cost is high

2. Physical difference: POF is thin and tough, with uniform thickness and soft texture. High tensile strength, high tear strength, adjustable shrinkage and better kneading resistance. PVC is thick and brittle with uneven thickness, poor moisture resistance and hard and brittle texture. Low strength and poor rubbing resistance

3. Safety difference: POF shrinkable packaging has soft corners, will not cut hands, and is resistant to rubbing. The four corners of PVC shrinkable packaging are hard and sharp, which is easy to cut and bleed

4. Environmental protection difference: POF is non-toxic and does not produce toxic smell during processing. PVC is toxic and will produce odor during processing

extended data

POF heat shrinkable film scope of action: it is widely used in the outer packaging and collective packaging of products in various industries such as cosmetics, gifts, drugs, audio-visual products, wood products, plastic hardware, daily necessities, etc. It is suitable for semi-automatic or full-automatic shrink packaging machine

PVC shrink film has a wide range of functions: packaging of wine, food, sporting goods, sterilized tableware, electronic appliances, daily necessities, handicrafts, building protection products, stationery, toys, plastic hardware, glass ceramics and other commodities

PVC material is PVC, which is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder, which can not be used alone and must be modified. PVC is a white powder with amorphous structure, with small branching degree and poor stability to light and heat. Different additives can be added according to different uses, and PVC plastics can show different physical and mechanical properties. A variety of hard, soft and transparent products can be made by adding an appropriate amount of plasticizer to PVC resin
environmental friendly POF shrinkable film is the abbreviation of biaxially stretched polyolefin shrinkable film. It is a new environmental friendly shrinkable film with the most extensive use and rapid development in the world. The product adopts the special process of advanced biaxial stretching three-layer melt coextrusion. The soft shrink film with high transparency, high shrinkage, high toughness, high heat sealing performance, antistatic, excellent cold resistance, safety and reliability is produced
the above is the answer from Shanzhang light industry. Hope to adopt it! If you need more information about printing packaging film, you can also log in to our official website to view more content, thank you!

PVC shrink film has the characteristics of high transparency, good gloss and high shrinkage. It has a long history and low price, but it is not environmentally friendly
POF shrinkable film has the characteristics of 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 material is superior to PVC. The advantages of POF heat shrinkable film can be summarized as follows:
1. Strength and toughness: obvious sealing, good shrinkage and tight molecular structure
2. High transparency: no pattern, no crystal point, high gloss and transparency
3. Uniform thickness: the sealing temperature is between 200-290 ℃, and the thickness is uniform
4. High shrinkage: POF film has extremely high shrinkage, so it is suitable for product packaging of various shapes
5. Strong cold resistance: POF film can maintain softness even at minus 20 degrees, and the product shrinkage is perfect.
