Multilayer Structure Plastic Compounds Barrier Bag Large Capacity Puncture

Engineered for the most demanding industrial and commercial storage challenges, the Fortis™ XL Pro-Shield Bag redefines large-scale containment with uncompromising barrier integrity. This extra-large format bag utilizes a sophisticated PET/AL/PA/PE multilayer co-extrusion structure, creating a synergistic defense system that surpasses conventional packaging. It is designed not merely to contain, but to actively preserve and protect high-value, sensitive, or bulk contents from environmental and physical threats throughout extended storage and rigorous supply chains.

The superior performance of the Fortis™ XL bag is a direct result of its purpose-engineered, four-layer laminate architecture. Each layer is precision-selected and bonded to perform a critical protective function:

• Outer Layer: PET (Polyethylene Terephthalate)

  • Primary Role: Mechanical Armor.

  • Benefits: Provides exceptional tensile strength, abrasion resistance, and a high-gloss surface. This layer shields against scuffs, punctures, and handling damage during transit and storage, ensuring the inner barriers remain intact.

• Core Barrier: AL (Aluminum)

  • Primary Role: Impermeable Shield.

  • Benefits: Forms a continuous metallic layer that delivers an absolute barrier to gases, moisture vapor, and light. It prevents oxygen ingress (oxidation), moisture migration (humidity damage), and UV degradation, which is critical for preserving product efficacy, flavor, color, and shelf life.

• Reinforcement Layer: PA (Polyamide / Nylon)

  • Primary Role: Structural Integrity.

  • Benefits: Imparts outstanding toughness, burst strength, and flex-crack resistance. This layer allows the bag to withstand significant stress, pressure from bulky contents, and dynamic impacts without tearing or developing pinholes that compromise barrier performance.

• Inner Layer: PE (Polyethylene)

  • Primary Role: Hermetic Sealant.

  • Benefits: Offers excellent heat-sealability, enabling the creation of strong, uniform, and airtight seams. This food-safe layer provides a reliable closure surface and is chemically compatible with a vast range of products.

• Ultimate Preservation Environment: Creates a dry, anaerobic, and light-free microclimate, ideal for products with strict stability requirements.

• Extra-Large Capacity & Custom Fit: Available in oversized dimensions to accommodate palletized goods, large machinery parts, bulk raw materials, or as a protective liner for Gaylord boxes, drums, and shipping containers. Custom sizing ensures a perfect fit for your application.

• Unmatched Durability: The combined strength of PET and PA yields a bag that resists puncturing from sharp corners, tearing under heavy weight, and abrasion from rough handling.

• Secure Sealing Compatibility: Compatible with industrial heat sealers, impulse sealers, and can be closed with high-strength tapes or ties, ensuring contents remain isolated from the external environment.

• Professional Utility: The metallic, opaque finish presents a clean, technical appearance suitable for B2B and high-value applications. Surface is suitable for direct thermal-transfer labeling or custom printing for traceability.

• Advanced Manufacturing & Aerospace: Storage of composite materials, precision engine components, and sensitive avionics.

• Chemical & Pharmaceutical: Packaging of hygroscopic raw materials, specialty chemical compounds, desiccants, and non-sterile medical device kits.

• Food & Specialty Agriculture: Bulk storage of coffee beans, spices, nuts, grains, and premium ingredients where flavor and freshness preservation are paramount.

• Electronics & Military Logistics: EMI/RFI shielding for components, long-term archival storage of sensitive equipment, and moisture-critical military supplies.

• Industrial Parts & Automotive: Corrosion protection for metal parts, gaskets, and assemblies during in-plant storage or overseas shipment.

• Structure: PET / AL / PA / PE Multilayer Laminate

• Barrier Properties: Extremely High (>99.9% effective against light, O₂, and H₂O vapor)

• Physical Properties: High puncture resistance, excellent tear strength, high-temperature resistant seal layer.

• Size Configuration: Offered in standard Extra Large formats (e.g., 30" x 40", 36" x 48") with full custom sizing and gauge/thickness options available.

• Closure: Open-top for flexible sealing solutions.
