The quality of PE foam material directly determines the sealing effect and service life. So what are the characteristics of "good" PE foam materials?
◆The closed cell rate reaches over 85%, with a closed cell structure where bubbles are independent and disconnected from each other. Water molecules cannot penetrate the pore walls, resulting in extremely low water absorption and good waterproof performance of the material.
◆Good compression resilience, able to recover to its original state even under long-term pressure. After multiple opening and closing cycles, the sealing performance does not deteriorate or slightly weakens but does not affect the sealing performance. This ensures stable sealing pressure when the bottle cap is tightened.
◆High strength, with a density of over 300kg/m ³ and a Shore hardness of over 50HA. The material is cut without burrs, has toughness, and is not easily wrinkled.
◆Non toxic and environmentally friendly, pure physical foaming. Not using chemical foaming to avoid chemical residues and withstand multiple tests.
◆High processing adaptability, stable size without change; Easy to die cut, film and print; The surface is flat without arching.
If you want a high-quality PE foam material, you may want to learn about BAIJUR's materials. After years of research and adaptation, BAIJUR's materials can meet the characteristics of "good" PE foam materials. In addition to PE foam materials, various film options (matte, glossy, high hardness, etc.) can also be provided. The material is suitable for die-cutting liners, composite, printing and other applications.
