zhiteng stretch film

  What are the criteria for selecting stretch film? Stretch film  is very convenient to use, with low cost and high efficiency. It is very popular in the packaging industry. Now there are more and more stretch film manufacturers on the market. How to choose stretch film, what is its standard, and what is it? High-quality stretch film products? What standards does it need to meet? Today, Zhiteng stretch film manufacturers will share with you. First, look at the transparency and gloss. A high-quality stretched film has good transparency and good gloss. When observed under the sun, it does not contain too many impurities and is relatively clean; Second, express shrinkage capacity, high-quality stretch film, when it passes through the thermal stretch film packaging machine, its shrinking ability is fast but the quality is poor, it will not shrink well, or it will have to go through two to three times of thermal stretch film Only the machine can complete the shrinking process. Thir...

  The difference between stretch film and wound film Stretch film  is mainly used for product packaging. For some companies, using stretch film to package products can effectively reduce the cost of use, while reducing labor intensity of workers, improving packaging efficiency and packaging grades. So what is the difference between stretch film and stretch film? Today, Zhiteng stretch film manufacturer will introduce to you. Stretch film, also called stretch film and heat shrink film, was originally produced with PVC as base material, DOA as plasticizer and self-adhesive effect. Due to environmental protection issues, high cost (relatively high relative to PE, less unit packaging area), poor stretchability, etc., when the production of PE stretch film began in 1994-1995, it was gradually eliminated. The PE stretch film first uses EVA as the self-adhesive material, but its cost is high, and it has a pungent odor, and then it is developed to use PIB and VLDPE as the self-adhesiv...

  What are the advantages of black stretch film in various industries Black stretch film  products can greatly reduce the cost of use, and packaging can reduce labor intensity of workers, improve packaging grades and packaging efficiency, and is expected to become the main force in the packaging market in the future. Stretch film has the characteristics of toughness, resistance to pulling, self-adhesiveness, low temperature resistance and good shrinkage. Generally, stretch films are divided into single-sided adhesive and double-sided adhesive. The total annual demand for black stretch film can reach about 60,000 tons, and the demand for stretch film is also increasing year by year, with an annual growth rate of about 6-7%, of which the growth rate of Southeast Asia is about 15%. The application field of stretch film is very wide.
