Bubble bags use PE as the core base material (and can be compounded with materials like aluminum plating or kraft paper). Through a special process, they are made into a bubble film structure with independent air cushion chambers. Utilizing air barrier to achieve shock absorption and cushioning, they balance basic protection and lightweight properties, and are widely used in packaging scenarios requiring anti-collision and anti-scratching—such as electronic products (mobile phones, earphones), fragile items (glass products, ceramics), precision parts, and cross-border e-commerce parcels.
Compared with regular PE bags/kraft paper envelopes, their core performance is significantly improved:
- Shock absorption and cushioning performance is increased by 60%-80%: The air cushion chambers can absorb over 80% of impact energy, reducing the transportation damage rate of fragile items from over 25% (with regular packaging) to below 5%—a decrease of more than 90%;
- Anti-scratching performance is enhanced by 35%-55%: The raised structure on the surface of the bubble film prevents direct friction between items inside the package, for example, reducing the scratch rate of electronic screens by 85% compared to regular PE bags;
- Moisture resistance is improved by 25%-40%: The PE base material combined with air barrier in the bubbles results in a moisture transmission rate 60% lower than that of kraft paper packaging, making it suitable for humid environments or cross-border sea shipping scenarios;
- Cushioning stability is boosted by 40%-60%: The independent bubble design avoids total cushioning failure caused by local damage, whereas regular foam packaging loses its protective effect once it breaks.
Compared with regular versions, it additionally has three core advantages:
- Multi-functional material adaptability: Customizable composite structures (e.g., aluminum-plated bubble bags for enhanced light resistance, kraft paper bubble bags for improved stiffness) are available, while regular PE bags/kraft paper envelopes only have single-material functions;
- Lightweight for cost reduction: It is 30%-40% lighter than foam packaging with equivalent protective effects, which can reduce logistics and transportation costs by 15%-20%, and also occupies less space for warehouse stacking;
- Eco-friendliness and reusability: PE-based bubble bags can be folded and reused 3-5 times, and are recyclable after disposal—more eco-friendly than disposable foam packaging, solving the pain point that regular cushioning materials are difficult to recycle.
