Our High Temp Retort PE/ALU Laminated Foil is developed for Chilean and Norwegian salmon bags, where high-temperature retort tolerance and seafood freshness must be handled together. The PE/ALU laminated structure combines a heat-sealable PE inner layer with a barrier aluminum core, allowing the pouch to withstand retort sterilization without delamination, leaking, or seal failure. The aluminum layer blocks oxygen, moisture, and light, helping preserve salmon color, texture, and natural oils during long shelf life and cold-chain distribution. The film is food-contact safe and suitable for retort pouches, vacuum bags, and skin-pack formats used by seafood processors, exporters, and private label brands. It also supports high-quality printing and branding for retail and foodservice markets. Custom roll widths, thickness structures, and printing layouts are available.

Applications
● New Energy Battery Encapsulation
Suitable for outer wrapping of 3C digital cell packs, casing of automotive power battery modules, and insulating separators for energy storage systems. The nylon layer and aluminum foil layer jointly form a dense composite barrier system, effectively resisting moisture ingress and chemical attack from electrolytes, while the accompanying functional resin layer ensures high-strength heat-seal closure and mechanical puncture resistance.
● High-Barrier Food Packaging
Suitable for roasted coffee bean packaging bags, high-temperature retort food pouches, and vacuum packaging for meat and cheese products. The dense aluminum foil layer provides complete barrier against oxygen, moisture, and ultraviolet radiation, preserving original contents flavor while significantly extending shelf life, with the heat-resistant film layers withstanding high-temperature sterilization without softening or deformation.
● Pharmaceutical & Medical Device Packaging
Suitable for pharmaceutical blister pack lidding films, sterile medical instrument sealing pouches, and in-vitro diagnostic kit encapsulation. The multi-layer composite structure is directionally engineered to create a sterile, moisture-resistant, and light-proof closed storage environment, with all performance attributes fully compliant with mandatory medical-grade hygiene and safety standards.
● Electronic Component Protective Packaging
Suitable for anti-static packaging of PCB boards, semiconductor chips, and precision sensing elements. The combined configuration of aluminum foil and metallized film layers delivers excellent static-discharge capability, electromagnetic interference shielding, and moisture cutoff performance, effectively preventing oxidation, moisture damage, or electrostatic breakdown of precision parts during logistics and warehousing.
● Industrial Chemicals & Agrochemical Packaging
Suitable for packaging containers for liquid fertilizers, pesticide formulations, and corrosive industrial chemicals. The reinforced multi-layer film structure offers exceptional chemical permeation resistance and internal pressure tolerance, ensuring safe storage and leak-free transport of hazardous substances and reactive liquids.
● Cosmetics & Personal Care Packaging
Suitable for shampoo single-use sachets, facial mask pouches, and cosmetic trial sample encapsulation. The outer-layer PET/BOPP premium printable substrate supports high-definition color printing to elevate brand visual appeal, while the inner sealant layer resists chemical swelling from cosmetic active ingredients and essential oils.
● Building Insulation & Moisture Vapor Barrier
Suitable for building roof radiant barrier layers, exterior wall insulation reflective membranes, and HVAC duct thermal insulation wraps. The pure aluminum foil surface efficiently reflects thermal radiation, while the backing reinforced film provides excellent tear strength and installation convenience for easy on-site cutting and application.
● Cable Shielding & Moisture-Proof Taping
Suitable for core shielding and longitudinal waterproof sealing of power cables, communication lines, and signal transmission wires. The aluminum-plastic composite structure delivers superior electromagnetic interference blocking and radial moisture protection, ensuring signal transmission stability and long-term reliability under demanding environmental conditions.

1. Ultimate barrier protection creates an isolated shield for the “micro-environment”
With a near-zero-permeation aluminum foil core as the main barrier and polymer functional layers on both sides, it delivers multiple lockdowns against moisture, oxygen, and light. It proactively suppresses three hidden risks—discoloration, molding, and active ingredient loss—giving food, pharmaceuticals, and electronic components a longer effective storage life, with quality promises backed by data.
2. Reinforced skeleton withstands “rough handling” in transport and processing
The embedded nylon/polyester skeleton layer builds a foundation of tear, puncture, and fatigue resistance: it keeps pace with high-speed line runs, survives repeated impacts in sea and land freight without leaking or breaking, and remains intact under battery swelling pressure, pressing transport damage rates toward zero.
3. Reliable sealing safeguards the product’s “second lifeline”
The heat-seal curve is precisely calibrated for automated filling rhythms, offering a broad sealing onset range and high bond strength, so edges stay closed through drops, pressure loads, and hot-cold cycling; in retort sterilization pouches, it also withstands high temperatures without leakage.
4. Wide thermal range and chemical resistance for truly harsh conditions
Across a wide thermal span from deep-freeze to retort sterilization, its performance curve stays flat, and it resists repeated attacks by electrolytes, solvents, and reagents. That is why it has long stood its ground in high-standard fields such as flexible lithium batteries and fine-chemical packaging.
5. Easy conformity to complex shapes with stable forming
Excellent elongation allows full control in stand-up pouches, vacuum bags, and irregular cell sealing; even with dense folds and curved surfaces, it shows no interlayer separation or corner cracking, producing finished packs with crisp edges and full, tight conformity.
6. High-appearance printing lets the package “speak up” on the shelf
With corona activation and primer coating, the surface takes ink firmly and finely, rendering matte, glossy, or metallic effects at will; prints come out brilliant and fade-proof for years, helping your brand close the first round of silent selling right at the shelf.
Benefits for Your Business
End-to-End Automated Control for Exceptional Aluminum-Plastic Composite Film
Leveraging fully automated high-speed lamination lines and precision slitting and winding equipment, we maintain complete in-house control from raw material formulation of aluminum foil and polymer pellets through multi-layer co-extrusion lamination and curing, to final slitting and packaging. Every batch of aluminum-plastic composite film undergoes online thickness monitoring and peel strength testing to ensure strong interlayer bonding, excellent barrier properties, and uniform thickness, meeting the stringent demands of diverse applications. Finished products are managed in standardized climate-controlled warehouses and shipped via efficient global logistics networks, ensuring every roll is delivered to customers on time and in perfect condition.
