Oct 30, 2017

The plastic shopping bag is the plastic bag which the consumer uses to fill the purchase goods, has the function. is made of resin as the main raw material, in sales, services and other places used for goods such as clothing, and used for carrying bags products.Plastic Shopping Bags

Plastic shopping bag is a daily consumption of consumables, China consumes a lot of plastic shopping bags every year. Plastic shopping bags in order to provide convenience for consumers at the same time, because of excessive use and recovery and treatment is not in place and other reasons, but also caused serious energy resources waste and environmental pollution. In particular, ultra-thin plastic shopping bags easily damaged, mostly discarded arbitrarily, become the "white pollution" the main source.Plastic Shopping Bags

Color direct contact with the food plastic shopping bag should be the true colors. Other plastic shopping bag ontology is generally true or white, or other colors. Appearance does not allow the use of air bubbles, perforation, plastic bad, fish eye stiffness and other defects. Bag film should be uniform, flat, no crease. Printing quality printing plastic shopping bags should be uniform ink, pattern, text clear, complete, overprinter accurate, overprinter error should be less than 1mm, printing stripping rate is less than 20%.Plastic Shopping Bags

Physical and mechanical properties should meet the requirements. Physical and mechanical properties requirements for project indicators lifting test three bags without rupture drop test three bags without rupture leakage three bags without leakage sealing strength See table 4 Dart Impact not rupture number ≥8 table 4 sealing strength required nominal load, kg sealing strength, n/15m4≤e<6 6.06≤e<10 8.0 ≥ 10 10.0.Plastic Shopping Bags

The standard classification of plastic shopping bags, including ordinary plastic shopping bags, degradable plastic shopping bags and starch-based plastic shopping bags, so as to facilitate consumer identification and classification of recycling. Plastic shopping bags for food must be labeled "food".Plastic Shopping Bags

Ordinary plastic shopping bag: using polyolefin and filler as raw material, this kind of plastic shopping bag does not have degradation performance, abandon in the field will not degrade. This kind of plastic shopping bag has excellent recyclable, can be recycled many times. The performance of recycled materials is slightly reduced, but it can be used in shopping bags or garbage bags with low production performance requirements and less stringent color requirements. The key question at the moment is whether it can be recycled back.Plastic Shopping Bags
