What Are The Manufacturing Processes For Food Packaging Boxes?

Food Packaging Box Manufacturing Processes

Oil Application: Applying a layer of printing oil to the printed surface after printing. This slightly increases gloss and provides abrasion and moisture resistance.

Varnishing: Applying a layer of thin plastic varnish to the printed surface after printing, followed by ironing with a high-temperature steel plate. This significantly improves the gloss of the printed material and provides abrasion and moisture resistance.

Lamination: Applying a layer of PE or BOPP plastic film to the printed surface after printing. This significantly improves the gloss, folding resistance, abrasion resistance, moisture resistance, and water resistance. Types include glossy film, matte film, and holographic film.

Lamination is one of the most common processes for food packaging boxes.

UV (Crystal): Applying a layer of UV varnish to the printed surface after printing, followed by drying with strong ultraviolet light. This significantly improves the gloss of the printed material and provides abrasion and moisture resistance.

Reverse UV coating: Reverse UV coating is a coating mode that combines spot varnishing and spot matte coating to achieve a high-contrast effect for specific areas of the image or text. Embossing, texturing, relief, raised printing, debossing: Creating raised or recessed patterns or text on a designated area of ​​the printed surface.

Hot stamping, also known as foil stamping, is a printing decoration process that involves heating a metal printing plate, applying foil, and pressing text or patterns onto the printed material.
