Detail Display
1： Material
Constructed from high‑quality multi‑layer co‑extruded PA+PE composite film. The PA layer delivers outstanding air‑locking property; PE layer improves tensile strength and puncture resistance. Material thickness can be adjusted upon custom requirements.
2： Heat‑sealing Craft
Each independent air chamber is formed by precision high‑temperature heat sealing. Firm sealing edges effectively reduce air‑leak risk. Stable air pressure can be maintained for weeks during sea freight, land transport and long‑term warehousing.
3：Physical Performance
– Good shock‑absorbing & anti‑collision capability. Independent air chambers disperse impact force from dropping, squeezing and vibration.
– Light‑weight material, will not add much extra shipping weight compared with foam, pearl cotton.
– Flat folded before inflation. Uninflated bags take minimal storage space, cutting warehouse occupancy and inbound freight costs.
Usage Notes
1. Do not over‑inflate. Moderate air pressure brings optimal cushioning effect; over‑inflation may cause burst under extrusion.
2. Keep away from sharp edges, burrs and sharp objects to avoid puncturing the film.
3. All sizes are custom‑produced. Please provide your carton **inner length × width × height** for accurate quotation and production.
