4. Pof shrink bags are thin and tough, with uniform thickness, good moisture resistance, soft texture, high tensile strength, tear-resistance, and adjustable shrinkable rate, as well as thanks to the existence of LLDPE, pof shrink wrap bags also hold good rub resistance.
5.Pof shrink bags for sale are also deft processing. During the processing, these polyolefin bags don’t produce moisture, and also can’t stick to the sealing rod, so it’s easy to maintain and work. High toughness, smoothness, and anti-rub properties make these first-class polyolefin shrink bags suitable for automatic packaging during high-speed production lines.
6. Pof shrink bags hold strong cold resistance. Even at so low temperature of -50℃, these polyolefin shrink bags wholesale aren’t hard and brittle, as well as can’t break, which are the best packaging products for frozen food packaging.
1.Generally speaking, bulk pof shrink bag is a new generation product that gradually rising and accepted by people in recent years, differ from the bubble wraps bags wholesale which mainly used the linear low-density LLDPE as the middle layer and PP as the inner and outer layer in specified equipment, interlined by special craft, these 3 layers of polyolefin heat shrink bags are extruded together, then we will get these heat shrinkable bags with high transparency and shrinkage rate, as well as great heat-sealing performance. These high-quality pof material shrink bags have all the advantages of polyethylene and polypropylene at the same time, however, pof shrink bags’ performance is far better than pure PE and PP bags, as the popular environmental protection materials, they are recognized by the European and American market, and widely used international these years.

2. Pof material bags are thin and tough, with high tensile strength and tear resistance, due to the usage of LLDPE, pof bags’ rubbing resistance is better. While PE materials bags are a little thinner than pof, also lower resistance strength than pof, but much higher than PVC, the PE’s shrinkage adjustability is poor, and rub resistance is not as thick and brittle as POF. Compared with PE and polyolefin shrink bags, PVC bags are uneven thickness, poor moisture resistance, hard and brittle texture, as well as low strength and shrinkage, that’s why we suggest that you’d better choose pof and polyolefin shrink bags Canada, especially for food.
3.Just as POF, PE shrink bags also hold strong cold resistance. Even in so low temperature of -50℃, these polyolefin shrink wrap bags aren’t hard and brittle, as well as can’t break, which also have great electrostatic elimination treatment, and can prevent items away from dust and moisture, effectively keep the product clean.
While PVC bags own poor cold resistance and will occur embrittlement in winter or after freezing, so it’s easy to crack in transportation. The longer the shrinking package is, the tighter the contraction will be, therefore, the packaging will be deformedeasily, What’s worse, PVC shrink bags also don’t have electrostatic elimination treatment, which is easy to be contaminated with dust, so that the product will make fuzzy pollution.
4. As mentioned above, PE and polyolefin shrink bags are easily maintained and work, however, in the process of PVC that can produce volatile matter, which will cause mechanical damage, and also can stick to the sealing rod, leading to poor operation and difficult maintenance.

1. Corona treatment.This means the pof bags’ surface is treated with a high voltage charge, thus achieve the purpose of strengthening surface energy and tension. Generally, we deal with the corona treatment in our factory, because of the time limitation to surface tension, in order to ensure your shrink bags’ high quality, Shie equipped several advanced types of equipment to do this work and offer you first-class kinds of cheap shrink bags for sale.
