Glass vacuum coating machine is an industrial equipment specially used to deposit one or more layers of thin film on the surface of glass bottles.

It uses physical vapor deposition technology under vacuum environment to achieve coating, and its main purpose is to give glass bottles new appearance or functional characteristics.

Decorative function

Metal film coating:

The most common ones are metal or alloy films such as aluminum, chrome, stainless steel, titanium, imitation gold, rose gold, etc., which make the glass bottle present a noble metallic luster (such as silver, gold, rose gold, gun color, etc.), improving the product grade and visual appeal.

Color film coating:

Various color effects can be achieved by controlling process parameters or using different targets.

Translucent/mirror effect coating: Controlling the thickness of the film layer can achieve different effects from translucent to highly reflective mirrors.

Protective function

Enhance surface hardness and wear resistance:

It can significantly improve the hardness and wear resistance of the glass bottle surface, reducing scratches during transportation and use.

Improve chemical stability:

The dense metal or oxide film layer can block the direct contact between the contents (especially certain corrosive or easily oxidized substances) and the glass, or prevent the external environment (such as humid air) from eroding the glass surface, thereby improving the corrosion resistance and service life of the bottle.

Applications:

Cosmetics and perfume industry

Core application areas:

High-end perfume bottles, essence bottles, cream bottles, foundation bottles, etc.

Application purpose:

Extremely luxurious appearance (metal texture, color effect, mirror effect), enhance brand image and product value, protect contents (light blocking, air blocking), and increase texture.

Wine and beverage industry

High-end liquor/foreign wine bottles:

Gold plating, silver plating, antique copper and other effects enhance the grade and show nobility.

High-end wine/champagne bottles:

Bottle neck coating (gold, silver) as decoration.

Functional beverage/health product bottles:

Aluminum or silicon oxide film layer is used to provide excellent oxygen and UV barrier properties to protect the activity and freshness of the content ingredients (such as vitamins, unsaturated fatty acids) and extend the shelf life.

Beer bottles (partial):

Mainly use the oxygen barrier and light-shielding properties of the aluminum film layer to improve the stability of beer flavor and extend the shelf life (commonly known as "aluminum film beer bottles").

Food industry

High-end condiment bottles (such as olive oil and vinegar): Use barrier coatings (aluminum plating, silicon oxide) to prevent oil oxidation and flavor loss, while improving appearance.

Special food packaging:

Foods with extremely high barrier requirements.

Gift and craft industry

Used as high-end gift packaging bottles (such as commemorative wine bottles, craft vases, decorative bottles), the unique metal or color coating effect enhances the artistic value and collection value.

Glass bottle vacuum coating machine is a key equipment to enhance the grade and functionality of glass packaging, especially in the field of high-end cosmetics, alcohol, medicine and health care product packaging, by giving the bottle a gorgeous appearance and strong protection/barrier performance to meet the dual needs of brands and consumers.
