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
- Lightweight: Polyethylene is very lightweight, making products made from it easy to carry and transport.
- Flexibility: LDPE bags, in particular, have good flexibility and stretchability and are not easy to break.
- waterproof and moisture-proof: good sealing performance ensures that the contents are not affected by external moisture.
- Strong corrosion resistance: good resistance to most acids and alkalis.
- low cost: compared with other materials, the production cost is lower, suitable for mass production and use.
- 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.
- Recyclable: Although it is difficult to degrade naturally after one-time use, it can still be re-processed and reused through specific processes.
Applications
- Application in daily life
- Shopping bag: widely used in supermarkets, convenience stores and other places to carry handles type shopping bags.
- Food preservation bags: used to store food and keep it fresh.
- Garbage bags: Small garbage bags used to collect waste in daily life.
- Industrial applications
- Agricultural mulching film: Used to cover farmland to keep heat and moisture and promote crop growth.
- Industrial packaging materials: such as chemical raw materials, electronic products and other commodities of the external protective layer.
- Medical packaging: such as disposable packaging for medical devices such as masks and gloves.
- Special Purpose Applications
- Anti-static bags: designed for electronic components to prevent static electricity from damaging sensitive components.
- Biodegradable bags: environmentally friendly bags produced with special formulas that can decompose faster under certain conditions to reduce environmental pollution.
