Poron: The Ultimate Solution for Advanced Packaging Applications

I. AN OVERVIEW ABOUT PORON MATERIAL

Poron is manufactured by continuously casting and curing mechanically frothed polyurethane foam to achieve the desired thickness and density. The foam cells consist of cell walls and voids. To obtain high-density polyurethane foam, the cell size is kept small. Each of these tiny cells acts like a miniature spring or energy absorber. For high-density foam, the cell walls occupy more space, resulting in very small cell sizes.

Furthermore, it has flame retardant properties (UL94 HBF) and excellent shock-absorbing capabilities. This is due to its unique cell structure, with an average cell size of about 100 microns, providing high density and uniformity. The material maintains excellent resistance to compression set, ensuring durable, long-term performance for gasketing applications. Sometimes,it can be cast onto polyester film (PET), which offers excellent support, stability, and balance. Additionally, it contains no plasticizers that could cause contamination.

III.APPLICATION OF PORON ON PACKAGING INDUSTRY

Poron is widely used in packaging due to its unique properties. Its applications span various industries, providing essential benefits such as protection, cushioning, and insulation. Here are some of the key applications of poron in packaging:

1. Protective Packaging

• Shock Absorption: Poron’s excellent shock-absorbing capabilities make it ideal for protecting delicate items during transit. It absorbs impacts and vibrations, preventing damage to sensitive products like electronics, medical devices, and fragile goods.

• Vibration Dampening: The material's ability to dampen vibrations ensures that items are securely cushioned, reducing the risk of damage from constant movement during shipping.

2. Cushioning

• Custom Foam Inserts: Poron can be cut and shaped into custom foam inserts tailored to fit specific products. These inserts provide a snug fit, preventing movement and ensuring that items remain in place.

5. Anti-Slip and Anti-Scratch Protection

• Surface Protection: Poron can be used as an anti-scratch and anti-slip layer in packaging to protect both the product and the packaging materials. It prevents scratches and abrasions during handling and transit.

• Non-Slip Pads: The foam can be applied as non-slip pads to ensure that packaged items do not slide around within the packaging, enhancing stability and protection.

6. Environmental Sustainability

• Recyclable Material: Poron is an environmentally friendly option as it is recyclable. Using Poron in packaging supports sustainable practices by reducing waste and promoting the use of recyclable materials.

• No Plasticizers: Poron contains no plasticizers, which can migrate and cause contamination, making it a safer and more environmentally friendly choice for packaging applications.
