chinese Polyolefin Shrink Film

chinese polyolefin shrink film

POLYOLEFIN SHRINK FILM, POF SHRINK FILM, biaxially oriented polyolefin shrink film referred to, it is one kind in the world using the most extensive, the rapid development of new environmentally friendly POLYOLEFIN SHRINK FILM. The product uses advanced two-way stretch 3 and 5 layer of molten special co-extrusion process. Produce a high transparency, high shrinkage, high toughness, high heat-sealing performance, anti-static, cold resistance excellent, safe and reliable soft POLYOLEFIN SHRINK FILM.

 POLYOLEFIN SHRINK FILM performance parameters table
POLYOLEFIN SHRINK FILM is widely used in various industries of food, cosmetics, gifts, medicines, stationery, toys, audio and video products, electronics, wood products, plastic hardware, daily necessities, such as product packaging and group packaging. This product is suitable for semi-automatic or fully automatic shrink packaging machine.
POLYOLEFIN SHRINK FILM, PE, PVC shrink film physical properties comparing
1. POLYOLEFIN SHRINK FILM the costs specific gravity 0.92, the thickness of the thinnest 0.012mm, lower the cost of the actual unit. PE specific gravity of 0.92, thinnest above 0.03, the higher the cost of the actual unit. The PVC specific gravity of 1.4, the thickness of the thinnest 0.02mm, the actual unit cost higher.

2.POLYOLEFIN SHRINK FILM, cold physical properties POLYOLEFIN SHRINK FILM cold resistance is excellent, -50 ℃ hard not brittle, difficult to break down, and can be used for frozen food packaging. Shrink packaging, -50 ° C - at 95 ° C long-term storage packaging stable and unchanging static and anti-fog treatment, less dust, pollution and keep the product clean and bright PE the cold hardiness Premium, winter or frozen, not hard, not brittle, so transportation is not easily broken. electrostatic eliminate processing , stained dust is not easy to keep the product clean PVC cold tolerance extremely inferior, winter or freezing occurs embrittlement, cracking of transport. longer the shrink-wrapping, shrink the tighter packaging deformation static elimination processing easy to dust, fuzzy pollution.
3. POLYOLEFIN SHRINK FILM processing performance, POLYOLEFIN SHRINK FILM process does not produce moisture does not stick to the cover stick, maintenance and operation easy high toughness, smooth and anti-rub resistance make it suitable for high-speed production line automatic packaging. PE processing The process does not produce water, non-stick seal stick, easy maintenance and operating high toughness, low rub resistance, can be used for higher speed automatic packaging production line, PVC processing will produce volatile, and could easily lead to mechanical damage, but also easy to stick to the cover stick, inconvenient operating and maintenance difficulties.

4. POLYOLEFIN SHRINK FILM physical properties of thin and tough, uniform thickness, good moisture resistance, soft texture and high tensile strength, tear resistance, adjustable shrinkage. Presence of LLDPE due to better rub resistance PE thick, tough, thickness uniform, good moisture resistance, texture soft. tear resistance below POLYOLEFIN SHRINK FILM, but much higher than PVC, shrinkage adjustable poor. rub resistance is better POLYOLEFIN SHRINK FILM PVC thick, brittle, uneven thickness, moisture resistance hard and brittle texture. intensity low, low shrinkage, and poor rub resistance.

5.POLYOLEFIN SHRINK FILM security POF SHRINK FILM shrink packaging, sealing at the four corners of the soft, will not cut staff, is also resistant to rub PE shrink wrapping, sealing the four corners of the soft, not cut staff PVC shrink wrapping, sealing hard and sharp at the four corners of the easy cuts bloodshed.
6. POLYOLEFIN SHRINK FILM environmental health, POF SHRINK FILM non-toxic, processing does not produce toxic odor, the U.S. FDA and USDA standards. PE non-toxic and does not produce toxic gases when processing the FDA and USDA compliant PVC toxic, processing will produce odor, toxic gases, gradually disabled.
