The production of our aluminum-plastic composite film (also known in the industry as foil-laminated film) relies on mature dry-bond lamination technology, whereby high-performance adhesive systems are employed to press aluminum foil substrates together with various polymer films (such as PET, PE, NY, CPP, OPP, and VMPET) layer by layer, achieving secure and uniform interfacial bonding between each layer and ultimately constructing a high-performance composite sheet with a multi-layered structure.
Within this composite system, the aluminum foil layer plays the role of functional core, bringing the finished product comprehensive barrier effectiveness against moisture, oxygen, light, and odor; while the individual plastic film layers each assume distinct functions, respectively providing water and moisture resistance, mechanical strength, heat-seal processability, surface printability, and chemical attack resistance alongside other physical and chemical properties. It is precisely this structural design of multi-material synergistic coordination that enables the finished composite film's comprehensive protective capability to far exceed what any single film could achieve; at the same time, its highly reflective surface characteristics also render the material broadly applicable in surface finishing applications within the thermal insulation field.

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.

Ultimate Barrier That Locks in Every Bit of Quality
The high-purity aluminum foil blocking layer at the film’s core works in concert with specialty polymer functional layers on both sides, building a defense line that intercepts moisture, oxygen, and UV at near-total rates. Oxidative discoloration, mold propagation, and active-ingredient decay—the three quality killers—are shut out entirely, earning foods, pharmaceuticals, and precision electronics a storage life and potency retention far beyond the conventional.
A “Soft Armor” That Stands Up to Rough Handling
The added nylon/polyester reinforcement layer gives the film a mechanical gene of combined strength and suppleness: under high-speed friction on automated lines, compression and vibration in cross-border transport, or even sustained pressure from battery cell swelling, it remains free of pinholes and tears—turning zero-damage delivery from a slogan into routine reality.
Seals That Hold, and Hold Firm
A wide-temperature heat-seal window and high-bond seal edges optimized specifically for high-speed automated filling ensure every seal stays flawlessly tight through drops, pressure loads, and thermal shifts—even in demanding uses like high-temperature retort pouches, it performs with zero leakage throughout.
Indifferent to Cold, Heat, and Chemicals
From -40°C-class deep-freeze storage to sterilization above 121°C, the film’s performance never drops off; it remains rock-solid against erosion by electrolytes, solvents, and chemical reagents, and has been repeatedly proven a high-reliability choice in flexible lithium battery encapsulation and industrial chemical packaging.
Conforming to Complex Shapes—Even at the Corners
Outstanding deep-draw elongation lets the film move effortlessly among stand-up pouches, vacuum bags, and irregular cell encapsulation—with no delamination and no corner cracking even under multi-curved, multi-folded geometries, presenting gap-free conformity and a professional sealing finish.
Printed Packaging with Built-In “Shelf Presence”
The film surface, treated with corona and primer coating, gives inks exceptional adhesion, and effects such as matte, mirror gloss, and brushed metal come with ease. The finished print is vivid, full-bodied, and fade-resistant for years, making your brand seen and remembered at first glance on the retail shelf.
