Bubble Bag

Bubble Bag is a packaging bag with an inner layer of bubble-shaped plastic film, mainly used for cushioning and shock absorption to protect fragile or precision items from impact during transportation. In foreign trade, it is a transport packaging auxiliary material, often used as inner packaging in conjunction with cartons. Usage scenarios include: protection of export goods such as electronic products, glassware, handicrafts, lighting fixtures, etc. Precautions: Select bubble diameter (common Φ10mm, Φ20mm) and bag thickness according to cargo weight and fragility; note that bubble bags themselves are not waterproof; if moisture protection is required, choose aluminum-coated or PE composite bubble bags; exports to the EU must comply with REACH requirements for plastic additives, and exports to the US must meet FDA food contact standards (if used for food packaging). Differences from other terms: Bubble Bag differs from Bubble Wrap—the former is a finished bag, while the latter is a roll material requiring cutting; compared with EPE Bag, bubble bags are thinner and lower in cost but slightly inferior in cushioning performance. Foreign trade contracts or letters of credit should specify specifications, gram weight, dimensions, and environmental requirements.
