POF and PE, PVC shrink film physics performance comparison
POF ( Environmental protection) Hot reduced film shorten PE film of PVC reduced film
1. Capital proportion of 0. 92, the thinnest thickness 0. 012 mm, the practice unit of capital is low. The proportion of 0. 92, the thinnest thickness 0. More than 3, the practice unit of capital is higher. The proportion of 1. 4, the thinnest thickness 0. 02 mm, practice unit of capital is higher.
2。 Thin and toughness in physical properties, uniform thickness, moisture resistance, texture is soft. High tensile strength, tear strength, shorten the rate is adjustable. Because of LLDPE, resistance to rub with the hands is very good. Thick and tough, even thickness, moisture resistance, texture is soft. Resistance to tear strength is lower than the POF, but much higher than PVC, shortening rate is adjustable. POF is better than to rub with the hands. Thick, brittle, thickness and moisture resistance is poor, texture hard brittle. Low intensity, shorten the low rate, poor resistance to rub with the hands.
3。 The cold resistance excellent commodity prices, - 50 ℃ hard brittle, not easy to break, can be used for frozen food packaging. After packing, - 50℃- - 95 ℃ are packing for a long time deposit, security remains the same. Electrostatic and anti-mist treatment, not pollution of dust, can insist on goods clean and bright. Cold resistance excellent, after the winter or frozen, not hard, not brittle, so shipping is not easy to break. Static elimination treatment, not easy to dye dust, can adhere to the commodity to clean. Cold resistance is extremely bad, winter or frozen will attack embrittlement, and therefore easy to break. Shorten the packing the longer, the more shorten, packaging deformation. To eliminate static electricity disposal, susceptible to dust, make commodity pollution.
4。 Function of machining process does not occur moisture also won't stick on the sealing bar, simple maintenance and work. High toughness, smooth and resistance to rub with the hands to make it suitable for high speed production line active packaging. Machining process without water, also do not stick on the sealing bar, simple maintenance and work. Gao Ren, low rub with the hands, can be used for relatively high-speed active packaging production line. Machining process can produce water, formation, mechanical damage and easy to stick on the sealing bar, work inconvenient, difficult maintenance. Post-press equipment
5. Security shorten after packaging, pincer-like device corners soft, not cut hands, also resistant to rub with the hands. Shorten after packaging, sealing the four soft, not cut staff. Shorten after packaging, hard and sharp corners pincer-like device, easy to cut bleeding.
6。 Environmental clean non-toxic paints, packaging processing will not occur when the poisonous smell, agree with the FDA and the USDA regulations. Non-toxic, processing will not occur when the toxic gas, agree with the FDA and the USDA regulations. Toxic, processing will occur odor, poisonous gas, disable step by step.
