Aluminum-plastic composite film (also referred to as foil-laminated film) is a multi-layered high-performance composite material, produced through advanced adhesive-based lamination technology that achieves secure interlayer bonding between aluminum foil substrates and various plastic film layers (including PET, PE, NY, CPP, OPP, and VMPET) .
Within this material system, the aluminum foil layer serves as the functional core—imparting the finished product with complete barrier performance against moisture vapor, oxygen, light transmission, and odor permeation; while the individual plastic layers each contribute distinct physical and chemical properties, encompassing moisture and water resistance, mechanical toughness, heat-seal formability, surface printability, and chemical resistance. The resulting flexible composite sheet, enabled by this multi-layer synergistic architecture, delivers comprehensive protective performance far beyond what any single material can achieve independently—while its highly reflective surface characteristics also make it extensively applicable in the surface finishing of thermal insulation materials.

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.

● Comprehensive Barrier with Near-Zero Permeability : Featuring a high-purity aluminum foil layer as the core barrier substrate, combined with specialized polymer functional layers, the film delivers near-complete (≥99.9%) blocking against moisture vapor, oxygen, and UV radiation. This dense protective system effectively inhibits oxidative reactions, mold growth, and active ingredient degradation, significantly extending the shelf life and potency retention period of food products, pharmaceuticals, and precision electronic components.
● Tough Puncture Resistance with Uncompromised Flexibility : Through the incorporation of premium nylon or polyester reinforcing layers, the product achieves excellent mechanical strength and puncture resistance while maintaining good flexibility. This ensures structural integrity—free from pinholes and tears under conditions such as high-speed automated packaging, long-distance logistics transport, or battery cell expansion pressure—delivering a zero-defect packaging protection solution.
● Broad Heat-Seal Window with Reliable Closure Strength : Engineered specifically for compatibility with high-speed automated filling lines, the film offers a wide heat-seal temperature window and high bond strength at the sealing interface. This guarantees secure, leak-proof seals capable of withstanding drop impacts and pressure differentials—maintaining zero-leakage performance even in demanding applications such as high-temperature retort pouches.
● Wide-Temperature Stability with Chemical Resistance : The product maintains stable performance across a broad temperature range—from deep-freeze conditions to high-temperature sterilization processes. It also offers excellent resistance to battery electrolytes, industrial solvents, and chemical reagents, demonstrating high reliability in demanding scenarios such as flexible lithium-ion battery encapsulation and industrial chemical packaging.
● High Draw-Formability for Complex Contours : The film features superior flexibility and deep-drawing capability, making it suitable for stand-up pouch formation, vacuum bag packaging, and irregular-shaped battery cell encapsulation—with no delamination or corner cracking under complex geometric conditions, ensuring fully conformal coverage and professional sealing performance.
● High-Definition Printability for Enhanced Shelf Appeal : The film surface offers excellent ink adhesion properties, supporting various surface finishes including matte, gloss, and metallic effects. We deliver vibrant, fade-resistant high-quality printed packaging that effectively strengthens brand visual identity and end-shelf competitive presence.
