Sep 05, 2017

     We all know that the strength of paper and water resistance are not good, many water-based products such as seafood can not be packaged, heavier metal products are also difficult to load. Even if we all use paper bags, how come the paper? First of all, the raw materials for making paper are mainly wood, and the world's forest resources are scarce, which is the biggest waste of the environment Therefore, a large number of paper bags are the largest waste of environmental resources, the largest environmental pollution.Plastic Shopping Bags

    Cotton linen shopping bag, cotton and hemp shopping bag strength is better than paper bag, can be used repeatedly, but water resistance is not good. The advantages of cotton and linen shopping bags are recyclable, but what about the bag? With washing is the most commonly used method, but washed waste water resources, with phosphorus-containing detergent will contaminate the soil, while ordinary washing and can not kill bacteria.Plastic Shopping Bags

    The plastic shopping bag is a packaging material made of polyolefin as the main raw material and suitable addition of other materials. Currently used Polyolefin mainly polyethylene (PE), commonly known as soft gum, the main products include low-density polyethylene or high-pressure polyethylene (LDPE), high-density polyethylene or low pressure polyethylene (HDPE), linear low-density polyethylene (LLDPE) and Metallocene polyethylene (MLLDPE) four categories. In order to reduce its cost, in recent years most companies have added about 30% calcium carbonate filled plastic shopping bags, this type of plastic shopping bags because of burning in the garbage dumps do not emit poisonous gas.Plastic Shopping Bags

    Ordinary plastic shopping bags-using polyolefin and fillers as raw materials, this type of plastic shopping bags do not have degradation performance, abandoned in the field will not be degraded. 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
