Bag Liners: PE/PP Inner Protection for FIBC & Woven Bags
Moisture and dust barrier. Aluminum foil composite and conductive options. Custom fit for all bag sizes.
Product Overview
Bag liners are inner protective inserts designed for FIBCs (ton bags), woven bags, and paper bags. They provide an additional barrier layer against moisture, dust, oxygen, and contamination, significantly enhancing the protective performance of outer packaging. BridgeX Pack offers PE liners, PP liners, aluminum foil composite liners, and conductive liners to match diverse cargo protection requirements.

Aluminum foil composite liners block oxygen and odors. Ideal for food and pharmaceutical products.
Anti-static & Conductive
Conductive PE liners with surface resistance <10⁶ Ω. Protects flammable powders.
Custom Fit
Manufactured to exact dimensions. Loose insert, tab-sealed, or form-fit styles.
Food-Grade Compliance
FDA and EU food-contact compliant materials for direct food contact.
Cost-Effective
Adding a liner is more economical than upgrading to fully laminated bags.
