  物理性能:
  Physical performance:
  強度:生產(chǎn)工藝中的擠出溫度、拉伸比等因素會影響塑料袋的強度。適當?shù)墓に噮?shù)可以使塑料袋具有較高的拉伸強度和抗撕裂性能,能夠承受一定的重量和外力。
  Strength: Factors such as extrusion temperature and stretch ratio in the production process can affect the strength of plastic bags. Appropriate process parameters can make plastic bags have high tensile strength and tear resistance, and can withstand certain weight and external forces.
  厚度均勻性:擠出過程中的溫度控制和模具設計對塑料袋的厚度均勻性關重要。厚度不均勻的塑料袋可能在使用過程中容易破裂,影響其使用壽命。
  Thickness uniformity: Temperature control and mold design during the extrusion process are crucial for the thickness uniformity of plastic bags. Plastic bags with uneven thickness may easily break during use, affecting their service life.

  透明度:原料的選擇和加工工藝會影響塑料袋的透明度。例如,采用高純度的原料和精細的加工工藝可以使塑料袋具有較高的透明度,便于觀察袋內物品。
  Transparency: The selection of raw materials and processing techniques can affect the transparency of plastic bags. For example, using high-purity raw materials and fine processing techniques can make plastic bags have high transparency, making it easier to observe the items inside the bag.
  化學性能:
  Chemical properties:
  穩(wěn)定性:塑料袋的生產(chǎn)工藝會影響其化學穩(wěn)定性。例如,PVC 塑料袋中含有較高比例的氯(Cl),在一定條件下可能會釋放出有害物質。而 PE 塑料袋相對較為穩(wěn)定,但在長期使用過程中也可能會受到光照、溫度等因素的影響,發(fā)生老化和降解。
  Stability: The production process of plastic bags can affect their chemical stability. For example, PVC plastic bags contain a high proportion of chlorine (Cl), which may release harmful substances under certain conditions. PE plastic bags are relatively stable, but they may also be affected by factors such as light and temperature during long-term use, leading to aging and degradation.
  耐腐蝕性:不同的生產(chǎn)工藝和原料會使塑料袋具有不同的耐腐蝕性。例如,一些特殊用途的塑料袋可能需要具有耐酸、耐堿等性能,這就需要在生產(chǎn)過程中選擇合適的原料和添加相應的助劑。
  Corrosion resistance: Different production processes and raw materials will make plastic bags have different corrosion resistance. For example, some special purpose plastic bags may require acid and alkali resistance, which requires selecting appropriate raw materials and adding corresponding additives during the production process.
