Waterproof Moisture Proof Aluminum Foil Laminated Polyester Film High Barrier Building Insulation

Waterproof moisture proof aluminum foil laminated polyester film is a high barrier composite material produced by bonding aluminum foil with polyester film. It is designed for building insulation, packaging and moisture proof wrapping where long term protection from water, moisture, oxygen and light is essential.

The aluminum layer acts as a strong barrier against water vapor, oxygen and UV light to prevent oxidation and spoilage, while the polyester layer adds mechanical strength, puncture resistance and waterproof integrity, so the material keeps its barrier performance even in humid environments.

This waterproof laminated film is available in silver or custom color with slitting width from 5 mm to 1600 mm, aluminum thickness 0.006 to 0.05 mm and PET thickness 0.012 to 0.05 mm. It can also be laminated with PE or kraft paper for extra stiffness and sealing.

• Corrosion Resistant: stable against humidity and chemicals
• Custom Width: slitting from 5 mm to 1600 mm
• Printability: supports brand printing and custom color
• Certification: ISO 9001:2015, SGS
• Extra Service: free samples and third-party inspection

• Building insulation and wall, roof and floor wrapping
• Moisture proof packaging for food, electronics and goods
• Vapor barrier for HVAC and insulation systems
• Pharmaceutical and cosmetic moisture proof packaging
• Industrial protective packaging and lamination
• Agricultural and construction moisture protection

We support customization of alloy grade, aluminum thickness, PET thickness, slitting width and color, and can laminate PE or kraft paper for extra sealing, stiffness and heat sealability.

OEM and ODM are supported with your own logo, printing and shipping marks, with flexible MOQ and fast sample turnaround for packaging and insulation projects.

Our technical team helps you select the right structure and thickness for your moisture barrier and insulation requirement, and confirms the water vapor and light barrier performance that best matches your application.

Mill test certificates, material certificates and third-party inspection reports such as SGS are supplied to support factory audit and customs clearance. Strict batch quality control guarantees stable barrier performance, adhesion and dimensional accuracy.

Each roll of waterproof moisture proof laminated film is wrapped with PE film and moisture-proof paper, then packed onto seaworthy export pallets or steel-framed crates with edge protectors.

Reinforced packing prevents moisture ingress and edge damage during long ocean transportation. Clear shipping marks and complete cargo documents are provided for smooth customs clearance.

Q1: What makes this film waterproof and moisture proof?
The aluminum foil layer forms a strong barrier against water vapor, oxygen and light, while the polyester layer seals the surface and adds waterproof integrity, so the material keeps moisture out in humid conditions.

Q2: What is the water vapor barrier performance?
The composite structure delivers a low water vapor transmission rate, effectively protecting packaged goods and building insulation from moisture, condensation and oxidation.

Q3: What applications does it suit?
It suits building insulation and wrapping, moisture proof packaging, vapor barriers, and pharmaceutical or cosmetic packaging where high barrier protection is required.

Q4: Does it resist light and oxygen?
Yes. The aluminum layer blocks light, oxygen and UV rays to prevent oxidation and spoilage, helping extend the shelf life of packaged products.

Q5: What widths and thicknesses are available?
We slit from 5 mm to 1600 mm width, with aluminum thickness 0.006 to 0.05 mm and PET thickness 0.012 to 0.05 mm to match different packaging and insulation lines.

Q6: Are you a real manufacturer?
Yes, we are a direct manufacturer with our own lamination and slitting lines, so we control quality and lead time and can offer factory-direct pricing.

Q7: Can you customize structure, color and printing?
Yes. We support OEM and ODM for alloy, thickness, width and color, and can laminate PE or kraft paper and print with your own logo and shipping marks.

Q8: Can I get free samples?
Yes, free samples are available for evaluation; you only pay the freight. You can verify the moisture barrier and strength before placing a mass order.

Q9: What is your MOQ and lead time?
Our MOQ is flexible, starting from 500 kilograms. Stock sizes ship within 7 - 20 working days, and custom production usually takes 15 - 25 working days.

Q10: How do I get a fast quotation?
