PE bag 12 reference standard

PE bag, is to choose the film grade of polyethylene particles, by blowing up or stretch processing method. With the development of the society, PE plastic bags in the market share is more and more big, widely used in clothing accessories, hardware machinery, logistics, express, furniture, electronic toys, household appliances, food, chemical industry and so on all walks of life, these products have brought great convenience to people's life. Now, professional manufacturer of flexible packaging shun xing source packaging is to interpret the article 12 of the reference standard of PE plastic bags. 1. Maintenance functions as a packing bag, PE bag for protection of the products is the most important, the most basic function. Assume that PE plastic bags for packaging products without strong protective effect, cause the loss of product damage or value, it will lose the value as the use of packaging. PE plastic bags to maintain function of the products is various, different products, different packing way, for the emphasis of the PE bag function requirements are also different. 2. Mechanical maintenance effect prevent leakage packaging products within or outside material into the packaging of the product damage and contamination. Direct reflection of PE plastic bags mechanical performance of the protection function, mechanical strength is mainly PE plastic bags, such as impact strength, tensile strength, tear strength, fall Outbid impact) And the puncture strength and so on. 3. Good welding strength of welding strength is also necessary for PE plastic bags protection products in a reliable way. Assume that the lack of weld strength, weld will be the Achilles' heel of the PE plastic bags, because the weld cracking and make the PE plastic bags lost the protection of product effect. 4. Blocking performance blocking performance refers to the PE plastic bags to prevent oxygen, carbon dioxide, nitrogen and other gases and aroma, such as water vapor through the function, the unclear scope, more commonly refers to the nonpolar gas such as oxygen, carbon dioxide, and nitrogen isolation. PE bag on the stand or fall of product display effect and film's own light transmittance, haze, gloss, antistatic, printing and other close relationship, demand cause foot light transmittance and fog degree of attention. 5. Light transmittance and fog light transmittance and fog degrees are packaged product visibility and one of the important indices for clarity, particularly on the relationship between the product display effect. Light transmittance and fog degrees are expressed as a percentage, the greater the light transmittance of value, show the transparency of PE plastic bags as possible; And the greater the degree of fog, it shows that through the PE plastic bags to observe the greater the turbidity of the object, namely clarity. 6. Luster gloss indicate the PE plastic bags in the light of reflective ability, to sample in the regular reflection direction, relative to the standard of surface reflectance brightness percentage said. 7. Antistatic property and with the rapid development of electronic industry, electronic circuit board integration is higher and higher. Use antistatic PE bag packaging products can prevent damage of electrostatic integrated circuit. 8. Good smooth good smooth will make packaging PE plastic bags move smoothly in packaging production line, to prevent damage due to too much resistance on the move, at the same time to achieve the purpose of easy opening. 9. High temperature resistant performance is often need to consider is resistant to high and low temperature function of PE plastic bags. 10. Health function when packing food or pharmaceuticals, selection of PE plastic bags necessary has the health functions of excellence, in line with the requirements of the relevant state health standards, to ensure that the PE plastic bags does not constitute to the contamination of the product packaging. 11. Air tightness good air tightness, gas can effectively isolate packaging container list of communication, it is need for most products. 12. Good moisture resistance of moisture resistance is effectively protect products, general PE plastic bags of moisture resistance increase with the increase of the thickness of the, with the temperature drop and smaller.
