Our Heat Reflective ALU/PET Composite Foil is purpose-built as an attic radiant barrier, addressing the radiant heat that accumulates beneath roof sheathing on hot, sunny days. The ALU/PET composite construction pairs a reflective aluminum surface with a PET reinforcement layer, giving the foil tear resistance and dimensional stability during cutting, stapling, and fitting between joists and rafters. The reflective surface redirects radiant heat outward instead of allowing it to radiate into the living space below, helping reduce attic heat buildup and ease demand on cooling systems. The material is lightweight, flexible, and roll-packed, making it practical for retrofit insulation and new residential construction. It also resists dust and moisture, supporting durable performance in vented attic conditions. Suitable for insulation contractors, roofing distributors, and energy efficiency retrofitters. Custom roll sizes, printing, and private labeling are available.

Applications
● Flexible Lithium Battery Packaging
Used as outer casing for 3C digital batteries, automotive power batteries and energy storage batteries. The nylon and aluminum foil layers deliver ultra-high barrier performance against moisture penetration and electrolyte corrosion, while the professional resin layer ensures superior heat-sealing stability and puncture resistance.
Used for coffee bags, high-temperature retort pouches, and vacuum packaging for meat and cheese products. The dense aluminum foil layer blocks oxygen, moisture and light to lock freshness and extend shelf life, while heat-resistant film layers withstand high-temperature sterilization.
● Pharmaceutical & Medical Packaging
Used for drug blister packs, sterile medical device pouches, and diagnostic kit packaging. The tailored multi-layer structure creates a sterile, moisture-proof and light-shielded packaging environment, fully compliant with strict medical-grade hygiene and safety standards.
● Electronics & Precision Component Shielding
Used for packaging PCB boards, semiconductors, and sensitive precision electronic components. The aluminum and metallized film layers provide excellent anti-static, EMI shielding and moisture barrier properties, effectively preventing component oxidation and electrostatic damage during transit and storage.
● Industrial Chemicals & Agricultural Packaging
Used for packaging liquid fertilizers, pesticides, and corrosive industrial chemicals. The robust multi-layer film structure resists chemical permeation and burst pressure, ensuring safe storage and leak-free transportation of hazardous and chemically sensitive liquids.
● Cosmetics & Personal Care Packaging
Used for shampoo sachets, facial mask bags, and cosmetic sample packaging. The premium printable PET/BOPP outer layer supports high-definition printing to upgrade brand aesthetics, while the inner sealant layer resists erosion from cosmetic active ingredients and essential oils.
● Insulation & Building Vapor Barrier
Used as radiant heat barriers for building roofs, wall insulation and HVAC duct insulation systems. The pure aluminum foil effectively reflects thermal radiation, while the durable film backing provides excellent tear resistance and convenient on-site installation.
Applied as a core shielding and moisture-proof layer in power, communication, and signal cables. The aluminum-plastic composite structure provides excellent electromagnetic interference (EMI) shielding and prevents water ingress, ensuring stable signal transmission and long-term durability in harsh environments.

● Ultimate Barrier Protection: Crafted with high-purity aluminum foil and specialized polymer layers, our composite films provide an exceptional 99.9% barrier against moisture, oxygen, and UV light. This superior isolation prevents oxidation, spoilage, and degradation, significantly extending the shelf life and maintaining the efficacy of food, pharmaceuticals, and sensitive electronics.
● High Tensile & Puncture Resistance: Engineered with premium Nylon (PA) or PET layers, our films deliver outstanding mechanical strength and puncture resistance while maintaining flexibility. This ensures structural integrity during high-speed packaging, rigorous transportation, or battery cell expansion, providing a zero-defect packaging solution that resists pinholing and tearing.
● Exceptional Heat Sealing Performance: Designed for seamless compatibility with automated packaging lines, our films feature a wide heat-sealing temperature range and high sealing strength. This guarantees secure, leak-proof seals that resist drop impacts and pressure changes, ensuring zero leakage even in demanding applications like high-temperature retort pouches.
● Extreme Temperature & Chemical Stability: Built to withstand harsh environments, our films maintain stable performance from deep freezing to high-temperature sterilization. Furthermore, they offer excellent resistance to battery electrolytes, industrial chemicals, and solvents, making them highly reliable for flexible lithium batteries and industrial packaging.
● Flexible & Conformable for Complex Shapes: Our films are designed with optimal flexibility and deep-drawing capabilities, making them perfect for forming stand-up pouches, vacuum bags, and complex battery cell packaging without delamination or corner cracking. This ensures full coverage and a tight, professional seal in even the most challenging geometries.
● High-Resolution Printing & Aesthetics: Our films feature excellent ink adhesion. Whether you require matte, glossy, or metallic finishes, we deliver visually striking, fade-resistant packaging that elevates your brand presence on the shelf.
