The Co-extruded Film Bubble Envelope Bags represent a next-generation protective mailer engineered for shipping fragile items in high-humidity environments. Traditional single-layer bubble envelopes fail in 35% of tropical shipping scenarios due to moisture ingress (Packaging Innovation Report 2024), making this 5-layer solution a critical upgrade. Constructed from 5-layer PE+PA co-extruded film (80–120gsm), it features a double-wall bubble grid sandwiched between moisture-resistant layers, delivering 5x stronger moisture resistance than standard mailers. The integrated self-sealing adhesive strip ensures tamper-evident closure, while CMYK full-color printing capability transforms functional packaging into a brand storytelling tool.
Ultra-Moisture Barrier System：Laminated PA (polyamide) layer forms a hydrophobic barrier that blocks up to 98% of ambient moisture, ideal for shipping cosmetics, pharmaceuticals, and electronics in humid regions like Southeast Asia and South America.
Space-Efficient Storage：Ships flat in stackable cartons, reducing warehouse space by 70% compared to pre-padded envelopes and lowering inbound shipping costs.
Custom Branding Capabilities：Supports high-resolution CMYK printing with full-color gamut coverage, allowing brands to feature logos, sustainability messages, or unboxing instructions directly on the envelope surface.
Eco-Responsible Design：Contains 20% post-consumer recycled content, is BPA-free, and recyclable through standard plastic recycling programs, meeting global safety standards while supporting sustainable packaging practices.
Full Bubbles：Provides full bubble cushioning to absorb shocks, protect against drops and impacts, and significantly reduce the risk of product damage during transit.
Self-Sealing Design：Tear-and-use design enables quick and convenient sealing, eliminating the need for additional tape or adhesives and speeding up the packing process.
Waterproof and Moisture-Proof：Effectively resists water and humidity, keeping products dry and intact throughout shipping, even in challenging weather or tropical climates.
High-Quality Adhesive Sealing：Uses high-temperature hot melt adhesive for strong and durable sealing; once sealed, the envelope cannot be reopened without visible tampering, ensuring product security.
E-commerce Shipping: Protects glass perfume bottles, ceramic jewelry, and small electronics during last-mile delivery, with the heavy-duty variant handling items up to 5kg.
Medical Logistics: Secures diagnostic test kits, sterile swabs, and temperature-sensitive pharmaceuticals in high-humidity regions, maintaining product efficacy.
Artisan & Handcrafted Goods: Safeguards handmade candles, natural soaps, and resin jewelry with premium packaging that enhances perceived value and reduces damage claims.
Retail Returns Management: Tamper-evident adhesive strip with “void if opened” messaging reduces fraudulent returns, while the durable construction withstands return shipping handling.
Clothing Packaging：Co - extruded Bubble Envelope Bags are ideal for packing clothes. The bubble layer offers cushioning, keeping garments like shirts or dresses in good shape during shipping and preventing wrinkles or minor damages.
Magazine and Book Shipping：When it comes to sending magazines or books, these bags work well. They protect the pages from bending and the covers from scratches, ensuring the reading materials arrive in perfect condition.
Picture Frame Protection：For picture frames, which are easily damaged, Co - extruded Bubble Envelope Bags provide excellent protection. The bubble padding absorbs shocks, preventing the glass from breaking and the frame from getting dented during transit.
Small Item Storage：These bags are also great for storing small items. Whether it's tiny toys or accessories, the bags keep them organized and shielded from dust and light impacts, making storage and transportation convenient.
