Poly bagging (Poly pack, polythene bags for packing) is a type of plastic packaging product made from polyethylene (Polyethylene, PE) material. Depending on its density, polyethylene can be categorized into three main types: low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE). These different types of polyethylene materials have their own unique physicochemical properties, and as a result the bags made from them vary in performance.

Features

  1. Lightweight: Polyethylene is very lightweight, making products made from it easy to carry and transport.
  2. Flexibility: LDPE bags, in particular, have good flexibility and stretchability and are not easy to break.
  3. waterproof and moisture-proof: good sealing performance ensures that the contents are not affected by external moisture.
  4. Strong corrosion resistance: good resistance to most acids and alkalis.
  5. low cost: compared with other materials, the production cost is lower, suitable for mass production and use.
  6. Transparent or semi-transparent: the color transparency of the material can be adjusted according to the need, so that it is convenient to view the internal items.
  7. Recyclable: Although it is difficult to degrade naturally after one-time use, it can still be re-processed and reused through specific processes.

Applications

  1. Application in daily life
    1. Shopping bag: widely used in supermarkets, convenience stores and other places to carry handles type shopping bags.
    2. Food preservation bags: used to store food and keep it fresh.
    3. Garbage bags: Small garbage bags used to collect waste in daily life.
  2. Industrial applications
    1. Agricultural mulching film: Used to cover farmland to keep heat and moisture and promote crop growth.
    2. Industrial packaging materials: such as chemical raw materials, electronic products and other commodities of the external protective layer.
    3. Medical packaging: such as disposable packaging for medical devices such as masks and gloves.
  3. Special Purpose Applications
    1. Anti-static bags: designed for electronic components to prevent static electricity from damaging sensitive components.
    2. Biodegradable bags: environmentally friendly bags produced with special formulas that can decompose faster under certain conditions to reduce environmental pollution.
