PE square bottom bags are a common type of plastic packaging bag. Thanks to their unique square bottom design and excellent performance, they are widely used in various fields.

The main material of PE square bottom bags is polyethylene, which has good tensile strength and abrasion resistance, effectively protecting the items inside from external factors. The square bottom design allows the bag to stand upright, making it easy to load and display products.

PE square bottom bags can be customized according to needs, with different thicknesses and sizes to meet various packaging requirements. The manufacturing process includes extrusion, printing, slitting, and bag making. This process is simple and efficient, allowing for large-scale production of standard PE square bottom bags.
