What are the key points of plastic shopping bag customization? What are the key points of plastic shopping bag customization? First of all, we need to understand what a plastic shopping bag is. The key to plastic packaging bags is a plastic packaging product made of polyolefin as a basic raw material and moderately added other compounds. The applied polyolefin is based on high pressure polyethylene (PE), also known as soft rubber. The basic commodities include high pressure polyethylene or high density polyethylene (LDPE), polyethylene plastic or bottom pressure high pressure polyethylene (HDPE), linear high pressure polyethylene (LLDPE) and metallocene material high pressure polyethylene (mLLDPE) four categories. In order to reduce its cost, most companies add 30% calcium bicarbonate to make filling plastic bags, which do not release harmful gases when incinerated in garbage stations. Introduction of key points 1. Regular size and specification of plastic shopping bags. Basic shopping bag specifications and specifications. Models are generally used (total width + side width)×To express the length, the key are the following types of specifications: (150+80)×240, (170+80)×280, (200+100)×320, (230+110)×350, (260+130)×410. (280+140)×440, (300+140)×480, (330+150)×520, (440+180)×680. (Unit: mm) 1. In addition to these three specifications, there is another specification that is“film thickness”, some plastic bag factories often omit“film thickness”, at this time you pay special attention, it is very likely that there is an insider hidden. The example shows that, for example, 320×200×100×0.025, the specifications of this bag are: length 320mm, total width 200mm, side total width 100mm, and the thickness of a single mask is 0.025mm (the plastic bag factory still uses“Silk”as a business, that is, 2.5 filaments). 2. Length×(overall width + edge holder)×Thin and thick, it is the requirement of the 'National Industry Standard of the Republic of China' on the 'Technical Standard for Environmental Protection, Safety and Generality of Marking of Plastic Packaging Bags' for the standard packaging bag specifications and packaging bag model specifications. One thing must pay attention to: the total width of the side = the pressing edge×2; Hospital outpatient CT packaging bags are not edge-pressed, and some text and graphic bags are not folded, and the large number in the formula calculation becomes 0. For example, 350×(230+110)×0.025, the specifications of this bag are: length 350mm, total width 230mm, side total width 110mm, and the thickness of the single mask is 0.025mm. Plastic shopping bags: 2 Classification of plastic shopping bags The national plastic packaging bag specification promulgated soon divides plastic packaging bags into the following three types: general plastic packaging bags——Using polyolefin and fillers as raw materials, this type of plastic packaging bag does not have dissolving properties, and it is not easy to dissolve in the suburbs. This type of plastic packaging bag has excellent recyclability and can be reused several times in the recycling system. The properties of the purchased material are reduced at slightly different levels, but can be used to make bags or plastic bags with less demanding property specifications and less stringent color tone specifications. The crucial question is whether it can be acquired home. Tapioca Starch-Based Plastic Packaging Bags——This type of packaging bag is based on the modified material tapioca starch, and a small amount of biodegradable raw materials is added to improve its characteristics. The plastic packaging bag can be dissolved in the countryside after being used. Degradable plastic bags——This type of packaging bag is made of completely degradable plastic as raw material and has the characteristics of complete dissolution. Commodities left in the suburbs can be completely dissolved into small-molecule water microbial strains, without all air pollution, and overseas marketing and promotion of this type of plastic packaging bags.
