What are the materials used for making polythene bag?

Polythene bags are typically made from low-density polyethylene (LDPE) or high-density polyethylene (HDPE). These materials are derived from petroleum and are known for their flexibility, durability, and resistance to moisture and chemicals. Other additives may also be included in the manufacturing process to enhance certain properties of the polythene bags, such as UV stabilizers for outdoor use or anti-static agents for electronic components.

- Polyethylene (PE) resin: Low- and high-density polyethylene (LDPE and HDPE) are the most common resins used in polythene bag production.
- Additives: These enhance the performance and properties of the bag, such as antioxidants, anti-static agents, colorants, and UV stabilizers.
- Masterbatches: Concentrated forms of additives that are added to the resin to achieve specific color or functional properties.
- Slip agents: Improve the flowability and prevent sticking of the molten resin during extrusion.
- Anti-block agents: Prevent the bags from sticking together during storage and handling.
