VMCH Coated Aluminum Foil

VMCH coated aluminum foil is a composite material coated with VMCH (ethylene-methyl methacrylate-vinyl chloride copolymer) coating on the surface of aluminum foil. It combines the excellent properties of aluminum foil with the protective function of VMCH coating and is widely used in food, medicine, industrial packaging and other fields.

Characteristics of vmch coated aluminum foil:

– Excellent barrier properties: VMCH coating has excellent gas barrier properties, which can effectively prevent the penetration of gases such as oxygen and water vapor, and extend the shelf life of the package contents.

– Good chemical resistance: It has good tolerance to chemicals such as acids, alkalis, and oils, and is suitable for a variety of packaging environments.

– Stable mechanical properties: The coating enhances the tear resistance and puncture resistance of aluminum foil and improves the mechanical strength of the packaging.

– Printing and processing adaptability: The surface is flat, suitable for printing and composite processing, and can meet the diverse packaging design needs.

Application area of vmch coated aluminium foil:

– Food packaging: Used for the packaging of meat, dairy products, snacks and other foods to prevent oxidation and deterioration and maintain the freshness of food.

– Pharmaceutical packaging: Aluminum blister foil packaging suitable for pharmaceuticals, providing good moisture-proof and oxygen-proof protection to ensure the quality of pharmaceuticals.

– Industrial packaging: Moisture-proof and anti-static packaging for electronic components, precision instruments and other products to protect products from environmental influences.

The production of VMCH coated aluminum foil usually includes the following steps:

– Preparation of aluminum foil substrate: Select high-purity aluminum foil as the substrate to ensure a clean and flat surface.

– Coating: Use a coating process to evenly coat the VMCH coating on the surface of the aluminum foil to control the coating thickness and uniformity.

– Curing treatment: The coating is cured by heating or ultraviolet irradiation to form a stable protective layer.

– Post-processing: Slitting, printing, laminating and other processing are performed according to demand to make the final product.

VMCH coated aluminum foil has become one of the important materials in the modern packaging industry due to its excellent performance and broad application prospects.
