The Surface Aluminized Bubble Envelope Bags redefine thermal protection in packaging, engineered to safeguard temperature-sensitive goods across extreme climate conditions. Constructed with 5-layer co-extruded PE+PA film (120–150gsm) and a vacuum-deposited aluminum layer (300nm thickness), this advanced structure reflects 97% of radiant heat (ASTM C1371) while delivering 10x stronger impact absorption than conventional bubble mailers. Unlike single-function thermal bags, it combines temperature stability with physical protection, making it indispensable for shipping pharmaceuticals, perishables, and electronics through harsh environments—from desert heat to frozen tundras.
Extreme Climate Protection: The aluminized layer creates a thermal barrier that blocks UV rays and radiant heat, while the PE+PA core insulates against temperature fluctuations, critical for vaccines and biologics.
Heavy-Duty Durability: The 150gsm variant withstands 200kg compression (ASTM D624) and resists punctures from sharp objects, ensuring integrity during rough handling.
Tamper-Evident Security: Equipped with a high-strength self-adhesive strip (3N/25mm peel strength per ASTM D3359) that leaves a visible "VOID" mark if opened, reducing shipping fraud risks.
Eco-Responsible Construction: Contains 20% post-consumer recycled content and is recyclable through specialized plastic-aluminum recycling streams, minimizing environmental impact.
Enhanced Impact Protection: Full bubble lining provides comprehensive cushioning, effectively absorbing shocks and reducing the risk of damage from drops, impacts, or rough handling.
Convenient Self-Sealing: Tear-and-use design allows quick, hassle-free sealing without the need for tape or additional tools, saving time in packaging operations.
Waterproof & Moisture-Resistant: Offers reliable protection against water, humidity, and other environmental factors, ensuring safe transport of sensitive or delicate items.
High-Strength Adhesive Seal: Premium hot-melt adhesive delivers a secure, tamper-resistant closure that maintains integrity during shipping and cannot be restored once opened.
Pharmaceuticals: Maintains the integrity of temperature-sensitive vaccines, insulin, and biologics during cold chain logistics, ensuring efficacy across long-distance shipments.
Food & Beverage: Protects chocolates, dairy, and gourmet snacks from melting in heat or freezing in cold environments, preserving freshness and quality.
Electronics: Safeguards lithium-ion batteries, circuit boards, and sensitive components from thermal risks and physical damage during transit.
Art & Collectibles: Shields paintings, photographs, and antiques from UV exposure and moisture, preserving valuable cultural and artistic items.
Stationery and Photo Packaging：The bubble layer inside can effectively prevent these items from being bent or scratched during transportation, ensuring they remain in good condition.
Small Gift and Card Shipping： They not only protect the gifts and cards from damage but also add a touch of elegance with the aluminized appearance, making the packages look more attractive.
Cosmetics Protection：The bubble padding safeguards bottles and tubes from breaking or leaking, while the aluminized layer gives an extra layer of protection and a premium look.
Textile Storage：The bubble structure keeps the fabrics from getting crushed, and the aluminized surface helps in maintaining the quality and appearance of the items.
Q: Can it be used for liquid packaging?
A: Yes, the multi-layer PE+PA film resists punctures and leaks, making it suitable for shipping liquid samples or cosmetic serums.
Q: Does it block light completely?
A: The vacuum-deposited aluminum layer provides 100% light-blocking capability, protecting photosensitive products like medications and film rolls.
Q: What’s the shelf life of unused envelopes?
A: When stored in cool (15–25°C), dry conditions away from direct sunlight, they maintain optimal performance for 24 months.
