HDPE Bags
High-Density Polyethylene
- Thinner and more durable.
- Has a wrinkled surface.
- Used for supermarket bags, garbage bags, and produce bags.
Production
Plastic bag production typically involves processing polymer raw materials into the desired form. At CDB facilities, the production process consists of the following fundamental steps.
Polyethylene (PE) is commonly used in plastic bag production, classified into two main types: low-density polyethylene (LDPE) and high-density polyethylene (HDPE). Raw materials can include granules or recycled plastic materials.
The raw material is melted in extrusion machines to produce a film. During this stage: plastic granules are heated and melted; the molten plastic is formed into a thin sheet (film) or expanded into a balloon shape by blowing; and the film is adjusted to the desired thickness and size.
The resulting plastic film is rolled and transferred to bag production machines. Shaping machines cut the film into the desired bag model, and details such as handle holes or reinforced handles can be added during cutting.
The sides, bottoms, or handles of the cut bags are sealed using heat-based joining methods to increase durability.
The produced bags are inspected, folded, packaged, and prepared for shipment.
