1235 aluminum foil is a foil product processed based on 1235 aluminum alloy, with an aluminum content of not less than 99.35%.

1235 aluminum foil is a high-purity aluminum product. This high purity endows the aluminum foil with various unique properties, making it highly attractive in a range of industrial and consumer applications.

1235 aluminum foil belongs to the 1xxx series commercial pure aluminum alloys. Due to its excellent formability, corrosion resistance, and lightweight characteristics, it is widely used. Because this alloy has comparable performance and higher availability, it is gradually replacing the older 1145 alloy in markets such as packaging and electronics.

1235 Aluminum Foil Surface Treatments

Embossed 1235 Aluminum Foil: Embossed 1235 aluminum foil has a textured surface created through embossing technology. The embossed pattern improves mechanical strength, enhances appearance, and provides better anti-slip and decorative effects. It is widely used in food packaging, insulation, and decorative applications.
Hydrophilic Coated 1235 Aluminum Foil: This type of 1235 aluminum foil is coated with a hydrophilic layer that allows water to spread evenly on the surface. It is mainly applied in heat exchangers, air conditioners, and refrigeration equipment, where it improves heat transfer efficiency and prevents water droplet accumulation.
Laminated 1235 Aluminum Foil: Laminated 1235 aluminum foil is combined with paper, plastic film, or other materials through lamination. This structure enhances barrier properties, mechanical strength, and sealing ability, making it ideal for flexible packaging, pharmaceutical packaging, and industrial insulation.
Color Coated 1235 Aluminum Foil: Color coated 1235 aluminum foil is produced by applying colored coatings to its surface. It provides excellent decorative effects, corrosion resistance, and durability. Commonly used in packaging, decorative panels, and specialty applications requiring visual appeal.
Coated 1235 Aluminum Foil: This product is treated with functional coatings such as lacquer, adhesive, or protective layers. Coated foil enhances corrosion resistance, printability, and sealing performance. It is widely applied in food containers, pharmaceuticals, and beverage packaging.
1235 Plain Aluminum Foil: 1235 plain aluminum foil is the uncoated, untreated version with a smooth, clean surface. It retains the natural properties of aluminum, including high ductility and excellent barrier performance. Commonly used in household foil, basic food packaging, and industrial applications.
Anodized 1235 Aluminum Foil: Anodized 1235 aluminum foil undergoes an electrochemical oxidation process, forming a protective oxide film on the surface. This treatment enhances corrosion resistance, surface hardness, and decorative appearance. Suitable for architectural, electronic, and decorative uses.
1235 Composite Aluminum Foil: Composite 1235 aluminum foil is manufactured by combining aluminum foil with other substrates (such as plastic film, kraft paper, or woven fabric). It provides superior barrier properties, mechanical strength, and tailored performance for packaging, insulation, and industrial purposes.
Heat Sealing Coated 1235 Aluminum Foil: This type of foil is coated with a special heat-sealable layer, enabling it to bond with other packaging materials when heated. It is extensively used in pharmaceutical blister packs, food lids, and beverage seals for secure and hygienic packaging.
Hydrophobic 1235 Aluminum Foil: Hydrophobic 1235 aluminum foil is treated with a water-repellent coating that prevents water adherence and droplet formation. It is widely applied in heat exchangers, air conditioning systems, and other applications requiring anti-condensation and anti-corrosion performance.
