Material and Structure
- Pressure bubble packaging paper: mainly made of paper materials such as kraft paper, and formed with concave and convex small bubble structures on the paper through special processes. This structure enables bubble wrap paper to have both the toughness and strength of paper, as well as the cushioning effect of bubbles.
- Bubble film: It is a product made from high-pressure polyethylene as the main raw material, supplemented with whitening agents, opening agents and other auxiliary materials, and extruded into bubbles at high temperature. The bubble layer of the bubble film is composed of continuous closed bubbles, which are filled with air, making the bubble film lightweight, transparent, and elastic.
Performance characteristics
- Buffer protection: Both have good buffering protection performance, but the bubble structure of the pressure bubble packaging paper may be more dense, providing stronger shock resistance in some cases. The bubble film, on the other hand, has a significant effect in absorbing impact forces due to the continuity and elasticity of its bubble layer.
- Moisture and dust prevention: Both bubble wrap and bubble wrap have certain moisture and dust prevention functions, but the specific effect may vary due to differences in material and structure.
- Environmental friendliness: Pressure foam packaging paper is usually made of recyclable and biodegradable paper materials, which is more in line with environmental protection concepts. Although bubble wrap can be recycled, its main raw material polyethylene has a longer degradation time and has a relatively greater impact on the environment.
Application scenarios
- Pressure foam packaging paper: Due to its unique material and structure, pressure foam packaging paper performs well in the packaging of fragile items such as electronic products and glass products. Meanwhile, it is also suitable for packaging large items to provide stable protection. In addition, bubble wrap is widely used in the field of food packaging due to its environmental friendliness.
- Bubble wrap: Due to its lightweight, transparent, and elastic characteristics, bubble wrap is widely used for packaging and filling various products. It can not only provide cushioning protection, but also increase the transparency and aesthetics of the packaging. Bubble wrap is widely used in packaging of electronic products, handicrafts, furniture, and other fields.
