Kraft paper composite air bubble film

By introducing a three-layer structure design—a high-density polyethylene layer, a linear low-density polyethylene layer, and a honeycomb plastic mesh layer—into kraft paper composite bubble wrap, combined with an antistatic agent and a nano-clay composite coating, the problem of the bubble wrap's fragile surface is solved, achieving a more effective packaging protection effect.

AI Technical Summary

Technical Problem

The surface of existing kraft paper composite bubble wrap is fragile and easily scratched or worn by sharp objects, causing it to lose its shock absorption and cushioning effect during transportation or storage, thus affecting the protective performance of the items inside the packaging.

Method used

The bubble film features a three-layer structure design consisting of a high-density polyethylene layer, a linear low-density polyethylene layer, and a honeycomb plastic mesh layer. Combined with an antistatic agent layer and a nano-clay composite coating, and bonded by a two-component polyurethane adhesive layer, it enhances the strength and flexibility of the bubble film and synergistically absorbs and disperses impact forces.

Benefits of technology

It provides more comprehensive protection, enhancing the abrasion resistance, puncture resistance, and tear resistance of bubble wrap, improving the overall strength and cushioning performance of packaging materials, and adapting to various packaging needs.
