低压432888com威尼斯人与高压432888com威尼斯人区别!

发布日期:2020-03-12 编辑:www.jnsuliao.com 点击:

  432888com威尼斯人是生活中必不可少的必需品之一,食品包装常见的材料有PE聚乙烯,PS聚苯乙烯,PS聚苯乙烯等。主要常见的432888com威尼斯人有低压432888com威尼斯人和高压432888com威尼斯人!今天小编分享一下低压432888com威尼斯人与高压432888com威尼斯人区别!
  Plastic bag is one of the essential necessities in life. The common materials for food packaging are PE polyethylene, PS polystyrene, PS polystyrene, etc. The main common plastic bags are low-pressure plastic bags and high-pressure plastic bags! Today, let's share the differences between low-pressure plastic bags and high-pressure plastic bags!
  低压432888com威尼斯人的制作材料:由高密度聚乙烯,主要特征质硬,手感非常爽,不透明,不易拉断。稳定性高,尺寸稳定性好,耐热性和机械强度大,对水蒸气阻隔性较高,透明度差。
  Low pressure plastic bag material: made of high-density polyethylene, the main feature is hard, very cool, opaque, not easy to break. High stability, good dimensional stability, high heat resistance and mechanical strength, high water vapor barrier, poor transparency.
  高压432888com威尼斯人的主要材料是低密度聚乙烯,主要特征:质软,透明度好,手感粘,易穿,强度低。具有较低的结晶度和软化点,柔软性和伸长率较好。耐冲击,高压432888com威尼斯人制作的厚度较低,所以需要的材料多余低压432888com威尼斯人。因此,高压432888com威尼斯人的价格会高一些!

  The main material of high-pressure plastic bag is low-density polyethylene. Its main characteristics are soft, transparent, sticky, easy to wear and low strength. It has lower crystallinity and softening point, better softness and elongation. Impact resistant, the thickness of high-pressure plastic bags is relatively low, so the required materials are redundant low-pressure plastic bags. Therefore, the price of high-pressure plastic bags will be higher!
  在使用范围上,高压膜常用于食品、日用、蔬菜、收缩、自粘等轻质包装膜及农业用地膜、棚膜、保鲜膜等;低压膜因其薄膜强度高,主要用于重包装膜、撕裂膜及背心袋等
  In the scope of application, high-pressure film is commonly used in light packaging film such as food, daily use, vegetable, shrink, self-adhesive, agricultural mulch film, shed film, fresh-keeping film, etc.; low-pressure film is mainly used in heavy packaging film, tear film, vest bag, etc. due to its high film strength
