Here are some methods that can improve the load-bearing capacity of plastic bulk bags:
Select high-quality materials: Choose high-strength and high-toughness plastic raw materials, such as high-molecular-weight polyethylene or specially modified polypropylene.
Apply coating on the inner surface of the bulk bag to enhance its sealing and tensile resistance, thereby improving the overall load-bearing capacity.
Strictly control the quality of each process during the production process, and promptly discover and deal with defects that may affect the load-bearing capacity.
Pre-treatment: For example, pre-stretching or modifying the plastic raw materials to improve their performance.
Multi-layer composite structure:
