PE Shrink Film PVC Shrink Film POF Shrink Film
Cost Specific gravity: 0.92g/cm3 Thickness: ≥0.03mm The actual unit cost is higher. Specific gravity: 1.4g/cm3 Thickness: ≥0.02mm The actual unit cost is higher. Specific gravity: 0.92g/cm3 Thickness: ≥0.012mm The actual unit cost is lower.
Physical Property Transparency varies with thickness. Difficult to shrink, high temperature required for shrinkage. Surface can withstand large pressure. Good transparency Extremely easy to shrink, with low temperature required. Longer shrink packaging will lead to tighter contraction and deformation of packaged goods. Extremely good transparency Easy to shrink, no deformation of goods. After shrink packaging, under -50~-95℃, goods allows for long-term storage, stability without deformation.
Thick and tough, soft texture Tensile strength, tear resistance lower than POF, much higher than PVC. Rub resistance lower than POF, higher than PVC. Bad shrinkage adjustability Good moisture resistance Thick and brittle, hard and brittle texture Low tensile strength, tear resistance Poor rub resistance Poor moisture resistance Thin and tough, soft texture High tensile strength, tear resistance Better rub resistance (LLDPE) Adjustable shrinkage Good moisture resistance
Excellent cold resistance, not stiff and brittle in winter or frozen, not easy to crack in transport. Poor cold resistance, not brittle in winter or frozen, easy cracking in transport. Extremely excellent resistance to cold, not hard and brittle under -50℃, not easily broken in transport, suitable for frozen food packaging.
Static elimination process makes it not easy to accumulate dust, thus keeping the product clean. No elimination process makes it easy to be contaminated by dust, making the product fuzzy. Static elimination and anti-fog treatment makes it difficult to accumulate dust, keeping the product clean and bright.
Processing performance In processing, it does not produce moisture, and does not stick to the sealing rod, with easy operation and maintenance. In processing, it will produce water, and is easy to stick to the sealing rod and lead to mechanical damage, with inconvenient operation and difficult maintenance. In processing, it does not produce moisture and stick to the sealing rod, with high toughness, smoothness, rub resistance, and easy operation and maintenance.
Security After shrink wrapping, four sealing corners are soft, which will not cut hands. After shrink wrapping, four sealing corners are hard and sharp, which are easy to cut hands. After shrink wrapping, four sealing corners are soft, which will not cut hands and resist rub.
Environmental health Non-toxicity: It does not generate toxic gases in processing. It is an environmentally friendly shrink film. Toxicity: It generates toxic gases in processing. It is not an environmentally friendly shrink film. Non-toxicity: It does not produce toxic gases in processing. It is a green shrink film.
