PE round bottom bag

Introduction to PE Round Bottom Bags (Round Bottom Self standing Bags/Curved Bottom Bags)

Core conclusion: PE round bottom bag is a self-supporting bag made of PE material with a circular heat sealing structure at the bottom, also known as a round bottom self-supporting bag or an arc-shaped bottom bag. Its core advantage is that the bottom is uniformly stressed and has stronger self-supporting stability. It is suitable for packaging circular/irregular items and has a slightly more complex process than square bottom bags, balancing practicality and adaptability.

Basic Definition and Core Structure

PE round bottom bags are made of polyethylene (PE) as raw material, and the bottom is made into a complete circular or curved structure through a special heat sealing process, which is different from the square splicing of square bottom bags.

• Structural features: The bottom is an integrated circular heat seal without splicing seams, and both sides can be paired with folded edges (organ structure) to enhance capacity

• Morphological features: The empty bag can be folded and placed flat, and after filling, it forms a cylindrical or elliptical shape. When standing on its own, the contact area with the ground is uniform

• Core advantages: The bottom has no sharp edges, the force is dispersed, the load-bearing capacity is more balanced, and it is not easily damaged due to local compression
