POF Shrink Wrap

Chinese supplier Xiamen Guanhua is a POF Shrink Wrap manufacturer with more than ten years of history. We have professional production equipment and full-time staff to provide you with professional services.

Environmentally friendly POF Shrink Wrap is short for bidirectional stretch polyolefin shrink film, which is a new type of environmentally friendly shrink film that is the most widely used and developing rapidly in the world. The product adopts the special process of advanced bidirectional drawing three-layer and five-layer melting co-extrusion. The production of high transparency, high shrinkage, high toughness, high heat sealing performance, anti-static, excellent cold resistance, safe and reliable soft shrink film.

Comparison of physical properties of POF, PE and PVC Shrink Wrap:

1.The POF ratio of cost is 0.92, the thickness is the thinnest 0.01mm, the actual unit cost is low. PE proportion 0.92, the thinnest thickness of 0.03 or more, the actual unit cost is higher. The specific gravity of PVC is 1.4, the thickness is the thinest 0.02mm, and the actual unit cost is higher.

2.Physical properties POF thin and tough, uniform thickness, good moisture resistance, soft texture. High tensile strength, tear resistance, adjustable shrinkage. Due to the presence of LLDPE, better kneading resistance. PE thick and tough, uniform thickness, good moisture resistance, soft texture. Tear resistance is lower than POF, but much higher than PVC, and the shrinkage rate is poor adjustable. Kneading resistance is not as good as POF. PVC thick and brittle, uneven thickness, poor moisture resistance, hard and brittle texture. Low strength, low shrinkage, poor kneading resistance.

3.Cold resistance and other physical properties POF cold resistance is excellent,-50℃ is not hard, not brittle, not easy to break, can be used for frozen food packaging. After shrink packaging, the packaged material is stored for a long time at -50℃ -95℃, stable and unchanged. Electrostatic and anti-fog treatment, not easy to pollute dust, can keep the product clean and bright. PE has excellent cold resistance, in winter or after freezing, it is not hard, not embrittlement, so it is not easy to break during transportation. Electrostatic elimination treatment, not easy to stain dust, can keep the product clean. PVC cold resistance is very poor, winter or freezing will occur embrittlement, so it is easy to break during transportation. The longer the shrink packaging, the tighter the contraction will be, and the packaged object will be deformed. No static elimination treatment, easy to be contaminated with dust, so that the product pollution fuzzy.

4.Processing performance POF processing process does not produce water and will not stick to the sealing rod, easy maintenance and operation. High toughness, smoothness and kneading resistance make it suitable for automatic packaging in high-speed production lines. PE processing does not produce water, nor does it stick to the sealing rod, easy maintenance and operation. High toughness, low kneading, can be used for high-speed production line automatic packaging. PVC processing process will produce volatile, easy to cause mechanical damage, and easy to stick to the sealing rod, inconvenient operation, difficult maintenance.

5.Safety After POF shrink packaging, the four corners of the seal are soft, will not cut hands, and can be rubbed. After PE shrink packaging, the sealing corners are soft and will not cut hands. After PVC shrink packaging, the four corners of the seal are hard and sharp, easy to cut and bleed.

6. Environmental hygiene POF is non-toxic, does not produce toxic odor during processing, in line with FDA and USDA standards. PE is non-toxic, does not produce toxic gases during processing, and meets the US FDA and USDA standards. PVC is toxic, processing will produce odor, toxic gas, gradually banned.
