Advantages of Waterproof Zippers in Cooler Bag Manufacturing

Waterproof, heat-resistant, and flexible zipper tooth belts and puller materials, commonly made of plastic or rubber, give coolers with this zipper higher waterproofing and insulation. The double-layer or back-to-back zipper structure ensures a good sealing effect. The preference for spherical or interlocking tooth shapes provides excellent sealing at the biting points. Smooth and tight zipper edges reduce gas leakage, ensuring the highest level of sealing for cooler bags and maintaining bag quality.

Advantages of High-Frequency Welding Technology in Cooler Bag Making

High-frequency technology rapidly generates a substantial amount of heat, significantly improving production efficiency and allowing for more effective manufacturing of products. The heat produced by high frequency penetrates materials, forming a strong bond and making the bonding of cooler bags produced using this technology more robust. This technology, by concentrating heat in a short time, prevents material deformation caused by prolonged heating, enhancing the durability of cooler bags. It also contributes to a more exquisite appearance, elevating the overall quality of the product.
