Aluminum-plated Foil Bag | 3-Layer Barrier Protection

Our aluminum-plated foil bag is a cost-effective barrier packaging solution that combines the visual appeal and protective properties of metallized film with the structural strength of a multi-layer laminate construction. Designed for electronics components, industrial parts, and products requiring moisture, oxygen, and light protection, these bags are widely used across manufacturing and distribution operations in Southeast Asia.

Aluminum-plated foil bags — also referred to as metallized bags — differ from solid aluminum foil bags in their construction: rather than a continuous foil layer, a thin aluminum coating is vacuum-deposited onto a polyester or polypropylene film. This creates a lightweight, flexible bag with strong barrier properties at a lower cost point than full foil laminates.

Key Features

Metallized Aluminum Coating

A thin layer of aluminum is vacuum-deposited onto the surface of the inner film, providing significant improvement over uncoated plastic bags in moisture and oxygen barrier performance. The metallized layer also gives the bag its characteristic silver appearance and provides partial electrostatic shielding.

Multi-layer Laminate Construction

Outer BOPP or PET film (printable, puncture-resistant) combined with metallized inner film and PE sealant layer. The laminate structure provides durability, flexibility, and consistent barrier performance across the bag surface.

Moisture and Oxygen Barrier

Aluminum-plated foil bags significantly reduce moisture vapor and oxygen transmission compared to standard polyethylene bags, extending product shelf life and protecting components from corrosion and oxidation during storage and transit.

Light Barrier

The reflective metallized surface blocks UV and visible light, protecting light-sensitive components, materials, and products from photodegradation during storage.

Cost-effective Alternative

For applications where the extreme barrier performance of solid aluminum foil is not required, aluminum-plated bags offer strong protection at a more economical price point — making them practical for higher-volume packaging runs.

Custom Sizes and Printing

Available in custom dimensions with optional logo printing, part number identification, and handling instructions on the outer surface.

Applications

Aluminum-plated foil bags are used across a broad range of applications where moderate-to-good barrier protection is required without the cost of solid foil laminates. Common uses include packaging for electronic accessories and cables, light-sensitive industrial components, promotional and retail product packaging, and components requiring moderate moisture protection during regional shipping.

Frequently Asked Questions

Q: What is the difference between aluminum-plated bags and solid aluminum foil bags?

Solid aluminum foil bags contain a continuous layer of aluminum foil (typically 7–12 microns thick), delivering near-zero moisture and oxygen transmission. Aluminum-plated bags have a much thinner aluminum coating (typically 0.01–0.05 microns) deposited by vacuum metallization — providing good but not equivalent barrier performance. For highly moisture-sensitive electronics, solid foil bags are recommended.

Q: Do aluminum-plated bags provide ESD protection?

The thin metallized layer provides partial electrostatic shielding but is not a substitute for dedicated ESD shielding bags with tested Faraday cage performance. For ESD-sensitive components, specify anti-static aluminum foil bags.

Q: Are custom sizes available?

Yes. All dimensions can be custom manufactured. Small batch orders are welcome.
