PE inner lamination for moisture protection, BOPP outer lamination for print quality and durability, or double lamination for maximum performance. Engineered for food, chemical, and moisture-sensitive products.
All specifications are fully customizable. Contact us to discuss your exact requirements.
| Inner Lamination | PE (polyethylene) — extrusion coated or film laminated |
|---|---|
| Outer Lamination | BOPP (biaxially oriented polypropylene) — glossy or matte |
| Double Lamination | PE inner + BOPP outer combined |
| PE Coating Weight | 15 – 40 GSM depending on barrier requirements |
| BOPP Film Thickness | 18 – 25 micron |
| Moisture Barrier (MVTR) | Significantly reduced vs unlaminated woven PP |
| Base Fabric | Woven polypropylene, 60 – 120 GSM |
| Print Compatibility | Up to 6-colour flexographic on BOPP surface (175 LPI) |
| Seal Method | Heat seal, fold-and-stitch, or adhesive closure |
| Food-Grade Options | Virgin PP base, FDA/CFIA compliant PE and BOPP films |
Sugar, flour, rice, and animal feed are hygroscopic — they absorb moisture from the air, causing clumping, spoilage, and weight discrepancies. PE inner lamination maintains product integrity from filling through warehouse storage to end-customer delivery. BOPP outer lamination adds retail shelf appeal for consumer-facing pack sizes.
Cementitious products and dry chemical powders are extremely sensitive to moisture exposure during storage and transport. PE laminated woven PP bags prevent premature hydration and hardening. The puncture resistance of the laminated structure withstands pallet stacking, forklift handling, and rough loading dock conditions common in construction supply chains.
Granular and powder fertilizers stored in unlaminated bags attract moisture that causes caking and nutrient degradation. Double-laminated bags protect product quality through extended warehouse and retail storage cycles. The BOPP outer layer resists scuffing and tearing during seasonal retail display, while the PE inner layer prevents moisture ingress even in humid storage conditions.

Learn More →Extrusion coating melts polyethylene directly onto the woven fabric surface, creating a thin, cost-effective moisture barrier. Film lamination bonds a pre-formed PE film to the fabric using adhesive, providing a thicker, more uniform barrier with better seal characteristics. Extrusion coating is more economical for standard moisture protection; film lamination is preferred when higher barrier performance or heat-seal closure is required.
Yes. Food-grade laminated bags are manufactured using virgin polypropylene base fabric with PE and BOPP films that comply with FDA and CFIA regulations for direct and indirect food contact. Certificates of compliance are provided with each food-grade order. The lamination layers themselves do not introduce any substances that would compromise food safety.
Laminated PP woven bags are recyclable through industrial polypropylene recycling streams, though the lamination layer must be accounted for in the recycling process. PE-laminated bags are widely accepted because both PP and PE are polyolefins and can be processed together in many recycling facilities. BOPP lamination is also compatible. We can advise on recyclability requirements specific to your region and industry.
Glossy BOPP provides high visual impact with vibrant colour reproduction, making it ideal for retail-facing products where shelf appeal matters. Matte BOPP offers a subdued, premium look and reduces glare, which some brands prefer for natural or organic product lines. Both finishes provide the same level of moisture protection and puncture resistance. The choice is purely aesthetic and brand-driven.
Lamination adds a moderate cost increment that varies with the type and weight of lamination layer, bag size, and order volume. PE inner lamination is the most cost-effective upgrade. BOPP outer lamination costs more due to the film and adhesive process. Double lamination combines both cost increments. In most cases, the cost of lamination is significantly less than the cost of product damage from moisture exposure, making it a net savings for moisture-sensitive products.
