POF anti-fog heat shrinkable film is a new type of environmentally friendly shrinkable film that is widely used in the market and is developing rapidly. The product adopts the advanced biaxial stretching three-layer, five-layer melt co-extrusion special process. Produce a soft shrink film with high transparency, high shrinkage, high toughness, high heat sealing performance, antistatic, excellent cold resistance, safe and reliable.

Comparison of the physical properties of POF with PE and PVC films:

• The thinnest thickness is 0.01mm, and the actual unit cost is lower. The thinnest thickness is more than 0.03, and the actual unit cost is higher. The thinnest thickness is 0.02mm, and the actual unit cost is higher.

• Physical Properties POF is thin and tough, with uniform thickness, good moisture resistance and soft texture. High tensile strength, high tear resistance and adjustable shrinkage. Due to the presence of LLDPE, the rubbing resistance is better. PE is thick and tough, with uniform thickness, good moisture resistance and soft texture. The tear resistance is lower than POF, but much higher than PVC, and the shrinkage rate is poorly adjustable. The rub resistance is not as good as POF. PVC is thick and brittle, with uneven thickness, poor moisture resistance, and hard and brittle texture. Low strength, low shrinkage, and poor rub resistance.

• Cold resistance and other physical properties POF has excellent cold resistance, -50 ℃ is not hard, not brittle, not easy to break, and can be used for frozen food packaging. After shrink wrapping, the packaged material can be stored at -50℃--95℃ for a long time, which is stable and unchanged. With static electricity and anti-fog treatment, it is not easy to contaminate dust, which can keep the product clean and bright. PE has excellent cold resistance. It does not become hard or brittle in winter or after freezing, so it is not easy to be broken during transportation. With static elimination treatment, it is not easy to get dust and can keep the product clean. PVC has extremely poor cold resistance and will become brittle in winter or after freezing, so it is easy to break during transportation. The longer the shrink packaging is, the tighter the shrinkage will be, and the packaged object will be deformed. No static elimination treatment, easy to be contaminated with dust, making the product contamination blurred.

• Processability The POF process does not produce moisture and does not adhere to the sealing rod, and is easy to maintain and operate. High toughness, smoothness and rub resistance make it suitable for automatic packaging on high-speed production lines. The PE processing process does not produce moisture, nor does it stick to the sealing rod, and it is easy to maintain and operate. High toughness, low kneading, can be used for automatic packaging in higher speed production lines. The PVC processing process will produce volatile matter, which is easy to cause mechanical damage, and is easy to stick to the sealing rod, which is inconvenient to operate and difficult to maintain.

• Safety After POF shrink packaging, the four corners of the seal are soft, will not cut people's hands, and are resistant to rubbing. After PE shrink packaging, the four corners of the seal are soft and will not cut people's hands. After PVC shrink packaging, the four corners of the seal are hard and sharp, which is easy to cut and bleed.

• Environmentally friendly and hygienic POF is non-toxic, does not produce toxic odor during processing, and complies with the US FDA and USDA standards. PE is non-toxic, does not produce toxic gas during processing, and complies with the US FDA and USDA standards. PVC is toxic, processing will produce odor, toxic gas, and gradually disabled.
