Chongqing Ruili Packaging & Printing supplies PA (Nylon) + PE laminated vacuum bags. The outer nylon layer delivers great puncture resistance and oxygen barrier performance, while the inner PE layer ensures reliable heat sealing. Clear transparent design allows easy product inspection. Food-grade compliant options are available for long-cycle cross-border sea and air shipment. We support one-stop customization on size, thickness and gravure printing, with full test documents for customs clearance. Ideal vacuum packaging for exported food and hardware spare parts.

1. Advantages of PA/PE Laminated Structure

PA Nylon layer: High puncture resistance, low-temperature flexibility and oxygen barrier. Resists tearing and abrasion during long-distance transit, remains flexible under frozen conditions. PE sealing layer: Stable heat seal strength, leak-proof sealing edge, compatible with most commercial vacuum sealers. Clear transparent pouch enables buyers to check goods directly. More cost-effective than aluminum foil bags for bulk export orders.

Note: Standard PA/PE bags are NOT light-proof. For light-sensitive, high-oil goods requiring extra-long shelf life, aluminum foil high-barrier bags are recommended.

2. Export Compliance & Test Documents

Food-contact grade bags come with SGS, FDA and EU 10/2011 test reports to meet import inspection requirements for Europe, America, Southeast Asia and other regions. BPA-free and phthalate-free raw materials, supporting REACH and EPR compliance. Material declarations and COA certificates can be provided separately for customs clearance.

3. Cross-border Application

✅ Food export: Frozen meat, seafood, ready meals, cured food, nuts, grains and dry goods for cold-chain shipping.

✅ Industrial export: Bearings, screws, metal fittings and machinery parts, vacuum-packed for moisture & rust prevention.

✅ Cross-border e-commerce: Amazon, Shopify, Shopee and other retail orders in small vacuum packs.

✅ Agricultural export: Mushrooms, local specialties, seeds and farm products.
