What is 14 micron x 920mm Waterproof Aluminum Foil?
This ultra-thin foil is manufactured using advanced technology, and despite its thin thickness, its barrier properties are excellent. HTMM takes a standard aluminum coil and cold-rolls it to 14 microns using state-of-the-art technology. Multiple annealing cycles result in an optimal molecular structure.

A width of 920 mm enables high-speed flexible packaging lines. Where previously the maximum width of foil converters was 700 mm, HTMM can now offer you foil in a standard width of 920 mm. Through a waterproofing treatment, the foil achieves extreme impermeability to gases such as oxygen and moisture, despite the metal's inherent permeability.
Utilizing 14 Micron x 920mm Aluminum Foil for Waterproof Applications
Ultra-thin aluminum foil for waterproof offer packaging manufacturers new possibilities through their outstanding barrier properties. However, to fulfill the waterproof functionality required in certain applications, the foil must undergo specialized processing refinements. This article details the key steps involved in readying 14 micron x 920mm aluminum foil for waterproof laminate and package structures.
Substrate Pretreatment
To prime the aluminum surface for waterproof coatings, a light acid cleaning removes any oxidation lingering from prior processing:
- Foil unwind stands pass rolls through acidic solutions to degrease and etch the surface at the atomic scale.
- Deionized water rinses flush away acid residues, yielding a super-smooth activated surface for maximum adhesion of subsequent treatments.
Surface Engineering
Specialized coatings imbue the aluminum foil for waterproof characteristics:
- Dual-layer pvd (physical vapor deposition) applies exceedingly thin metallization like aluminum-silicone-aluminum with angstrom precision.
- Alternate options employ chemical vapor deposition to form passive oxide barriers or sputtered SiOx layers a few nanometers thick.
- Curing heat treatments finalize the engineered coating’s molecular structure and extremely low gas/moisture transmission properties.
Laminate Formation
Water Resistant Roof Foil typically interfaces with polymers to form high-barrier laminate structures:
- Pre-treated 14 micron foil unwinds continuously into multi-layer co-extrusion or lamination processes.
- Prime quality low-density polyethylene, polypropylene or nylon films adhere to the coated aluminum surface under pressure rolls.
- Optional printing technologies like rotogravure or flexo apply versatile graphics prior to polymer overlay.
- Precision slitting stations cut the high-barrier laminate into rolls for downstream packaging converting use.
Package Manufacturing
Leading flexible package formats benefit from the laminate’s impressive barrier traits:
- Pouches, trays and lids are thermoformed from the lamination stock on high-speed equipment.
- Form-fill-seal operations produce arrayed products like coffee cartridges or single-serve snacks.
- High-moisture, extended shelf-life applications are enabled by the laminate’s extreme waterproof efficacy.

Through these customized processes, Water Resistant Roof Foil is transformed into high-performance laminate and package substrates meeting demanding market needs. Its attributes unlock sustainable packaging innovations.
The Industrial Uses of 14 Micron x 920mm Waterproof Aluminum Foil
Ultra-thin Custom 14mic*920mm aluminum foil wholesale have not only revolutionized flexible consumer packaging applications but also found growing use in industrial sectors thanks to their exceptional barrier properties. This article explores some of the key opportunities this specialized material has created in demanding manufacturing environments.
Heavy Machinery Components
Custom 14mic*920mm aluminum foil wholesale forms reliable gaskets and seals within engines, compressors and hydraulic systems where tight permeability is critical:
- Cylinder head and valve cover gaskets use 11 micron foil laminated to nitrile or silicone to prevent combustion gas/coolant leaks over hundreds of thermal cycles.
- Hydraulic press and gear pump seals employ 12 micron foil-reinforced rubber to isolate hydraulic fluid from outside contamination indefinitely.
- Agricultural and construction equipment fuel tank breathers rely on 10 micron laminate valves to vent pressure changes while maintaining moisture-proof containment.
Chemical Shipping Liners
The foil's resistance to aggressive chemicals expands safe transportation options:
- 15 micron laminate-lined 55-gallon drums hold solvents, paint thinners and degreasers securely during forklift transport and storage without permeation risk.
- Foldable tanker curtains fabricated from 17 micron foil sheeting isolate potent liquid compartments from one another for multi-product hauls.
- Vegetable oil, wine and juice flexitanks employ a 10 micron liner as an alternative to rigid IBC totes for overseas shipments.
Battery Components
Batteries leverage its robust permeability barrier:
- 8 micron aluminum/nylon-reinforced microporous plastic laminate creates ultra high-vacuum packaging for lithium-ion cell electrodes.
- 12 micron metallized film wound cores isolate individual lead-acid car battery plates, improving cycle life in extreme conditions.
- Aluminized polyester wrappers surrounding consumer batteries prevent detrimental gases/moisture exchange through package shelf lives.
This specialized material's extreme barrier traits unlock performance upgrades across industrial sectors wherever separating fluids, gases or volatile chemicals is paramount for durability, function and safety.
Superior barrier with less material
14mic aluminum foil for waterproof construction uses its vast surface area to minimize permeation pathways for superior barrier performance, which can reduce plastic by 30-50% in applications such as coffee bags.
Enabling Design Innovation
The ultra-thin and wide gauge rolls liberate packaging designers. Using waterproof aluminum foil, brands can create dramatic visuals onstand-up pouches and do so more sustainably,
Opportunities in New Market Segments
Improved performance has expanded the material’s reach. For example, a major coffee producer employs an 11 micron laminate for single-serve cartridge packaging due to its ample barrier eliminating off-tastes from oxygen ingress compared to plastic.
Other growth areas cited include cosmetics, dietary supplements, teas and prepared food trays.
