Coated Aluminium for Closure Caps

Coated aluminum is widely used to make sealing closures for a variety of products, including beverages, pharmaceuticals and cosmetics. These closures, often called bottle caps or screw caps, are essential for sealing the container and maintaining the integrity of its contents.

Haomei Aluminum foil is used to produce anti-theft caps and bottle caps for the beverage and cosmetic industries as well as the pharmaceutical industry. The coated coils are formulated with a special resin to support the demanding sterilization processes of the pharmaceutical and cosmetic industries, thus guaranteeing the highest quality and hygiene. In addition, they are suitable for use in contact with food.

Coatings on aluminum closures serve multiple purposes

• 1. Protection: Coatings provide an additional layer of protection to aluminum surfaces, enhancing their durability and resistance to scratches and other forms of damage.
• 2. Decoration: Coatings can be applied to aluminum bottle caps to add decorative elements such as color, luster or texture to enhance the visual appeal of the packaging.
• 3. Barrier properties: Some coatings can improve the barrier properties of the closure, helping to prevent moisture, oxygen and other gases from penetrating the closure and affecting the contents of the container.
• 4. Brand identity: The coating can be customized to reflect the product’s brand identity, helping to enhance brand recognition and consumer loyalty.

Haomei Aluminum supplies Coated Aluminum for Closure Caps to manufacturers of screw caps, vial caps, tear-off caps and tamper-evident caps. The aluminum cover protects the essential functionality of the product and protects it from moisture, oxygen and microbial contamination.

Coated Aluminum Foil for Closures and Caps Applications

certainly! Coated aluminum foil is widely used in various industries, mainly due to its excellent barrier properties, versatility and easy customization. Let’s take a closer look at its applications and a detailed introduction to commonly used coating types:

Coated Aluminum Foil for Closures and Caps Pharmaceutical Packing

Caps, seals and vials: In pharmaceutical packaging, specially coated aluminum foil effectively blocks moisture, oxygen and other contaminants, ensuring the integrity and longevity of sensitive pharmaceuticals. Coatings such as heat seal paint or cold form paint are often used to promote sealing and protect the contents from external factors.

"Theft-proof" closure: Theft-proof closure is designed to provide tamper resistance and protect pharmaceutical products from unauthorized access or tampering. Aluminum foil is coated with a special adhesive or tamper-resistant coating to enhance security and ensure product safety.

Coated Aluminum Foil for Closures and Caps Cosmetics Packing

Lids and Containers: Aluminum foil coated with a decorative or protective coating is used in cosmetic packaging of a variety of products, such as creams, lotions, and powders. These coatings enhance the aesthetics of the packaging while also providing a barrier against external elements.

Coated Aluminum Foil for Closures and Caps Beverage Packing

ROPP Caps: Roll-on pilfer-proof (ROPP) caps are commonly used in the beverage industry to seal bottles containing alcoholic beverages, juices, or other beverages. Use aluminum foil with a special coating such as PVC or PVDC to ensure the integrity of the seal and prevent leakage or tampering.

PP Caps: Polypropylene (PP) caps are commonly used to seal beverage containers. Aluminum foil is coated with a coating such as heat-seal paint or pressure-sensitive adhesive to promote a secure seal and maintain product freshness.

Anti-theft caps: Similar to pharmaceutical anti-theft caps, aluminum foil coated with an anti-theft coating or special adhesive is used in beverage packaging to prevent tampering and ensure product security.
