pvc bags are widely used reasons, PVC bags will have these two advantages, mainly its consumption process. PVC bag consumption process is not complicated, the ordinary consumer line generally by the rolling machine, printing presses, backcoit machine and cutting machine, mainly through the roller straight stirring, roller rotation and high temperature rolling consumption out Thin film thickness, consumption at the same time and through the printing press in front of the film printed on the color, through the back of the machine in the film attached to the back of a layer of back coating.
This layer of backcoat seems to be a small step, but it is absolutely important and indispensable, it is an important guarantee for the quality of PVC bags.
The backcoat is made of special data, is a high-energy affinity agent, it is because of this layer of back coating, PVC film and tightly in the MDF or other plates together in order to adhere to a long time without opening plastic. The biggest problem with the ordinary paste mask is unable to deal with the problem of film fragmentation.
PVC bags with high-grade matte PVC information from the heat, with a beautiful and durable, the use of lunch, soft, affordable and other characteristics, high-quality high-transparent PVC manufacturing, unique anti-static accessories, bags are not sticky, the use of lunch, work precision Angle without burr, do not hurt the hand, zipper smooth use at the same time long life, sealing pressure tight, not fragile. Is a variety of underwear, socks, document materials, cosmetics, home appliances, home textiles and other promotional packaging the best choice.
Can PVC bag be filled with temperature?
PVC bags to meet the needs of a variety of places friends, but on the use of such products still have some problems, the use of such materials to keep the document material is no problem, moisture and very waterproof, will not let the internal material Damage, but used to install some of the temperature of the food will not be a problem, it will not produce other plastic products toxins harm the human body health
As pvc bag is the original pvc, and pvc is vinyl chloride in the initiator under the action of polymerization of thermoplastic resin. Is the homopolymer of vinyl chloride, vinyl chloride homopolymer and vinyl chloride copolymer collectively referred to as vinyl chloride resin.
Most of the PVC bags are non-toxic harmless, on the consumer manufacturers have played before the factory has stopped the test, so the quality is no problem.
Do not advocate friends with such a PVC material packaging bags to install hot water, because the hot water will make the product of a certain chemical changes, although not the formation of lethal toxins but also is not conducive to well-being. The academic solution is this: pvc no fixed melting point, 80 ~ 85 ℃ began to soften, 130 ℃ into a viscous state, 160 ~ 180 ℃ began to change into a viscous flow; have good mechanical properties, tensile strength 60MPa , The impact strength of 5 ~ 10kJ / m2; have excellent dielectric properties. But the stability of light and heat is poor, more than 100 ℃ or prolonged sun exposure, will be synthesized and produce hydrogen chloride, and further automatic catalytic synthesis, causing discoloration, physical and mechanical properties are also rapidly landing, in practice, Stabilizers to improve the stability of heat and light.
