  1、 Description of overall characteristics of PE materials.

  Transparent in appearance, but with a sense of atomization; Soft and resilient to the touch; Good low-temperature resistance and strong moisture resistance, but low barrier to oxygen and air; Its printing performance is poor, but after modification or treatment, it can print light colors, and it is not recommended to print large areas of dark colors.

  2、 The commonly used classification of packaging bag material PE in food packaging.

  According to production processes, PE can be divided into three categories: high-density HDPE, low-density LDPE, and linear low-density LLDPE. Their application emphasis in food packaging bags varies, and their performance also varies slightly.

  High density HDPE material, also known as low-pressure polyethylene, has excellent performance in high temperature and oil resistance. It can be used as a heat sealing layer in packaging bags for meat and fried foods.

  Low density LDPE material, commonly known as high-pressure polyethylene, is the softest type of PE material. It can be used as a separate packaging bag for transportation of frozen and refrigerated foods such as fresh fruits and meat. Or food shopping plastic bags, preservation bags, etc.

  Linear low-density LLDPE material, similar in appearance to LDPE, has excellent low-temperature toughness, impact resistance, stress cracking resistance, and fatigue resistance, all of which are particularly good. In frozen food packaging bags: ice-cream, ice cream, Rice-meat dumplings, quick-frozen dumplings and other packaging bags, LLDPE materials are used for heat sealing.

  Method for distinguishing between high-density and low-density PE materials:

  If a person has a delicate touch, they can compare the softness of the two, with a low-density texture being softer.

  2. Scratch the material with your nails, and the one that won't leave any scratches is high-density HDPE material. Conversely, it is low-density LDPE.

  3、 Food packaging bags made of PE material.

  PE material is one of the most commonly used materials in Rongchang packaging, which can be used as a single film bag or as a heat sealing layer for composite bags.
