Beer Box Knowledge

Beer boxes are paper boxes made by pressing paperboard into shape with a die-cutting machine and then glued together, primarily composed of corrugated paperboard.

Beer boxes come in various types such as the bottom-locked box, double-socket box, and airplane box, featuring lightweight, easy transportation and storage, and cost-effectiveness. Each type is applied to different product packaging based on its unique characteristics.

　　Manufacturing Process

1. Paper selection: Standard beer box wrapping paper is typically made from double copper or matte copper paper, with a weight of 128G, 105G, or 157G. Rarely do beer boxes have wrapping paper over 200G, as thicker paper tends to bubble when laminated and looks rather dull. Laminating paper is chosen based on the customer's requirements, commonly known as gray board or gray card paper.

2. Die-cutting: Current beer boxes emphasize aesthetic beauty, so the colors used in the die-cutting are diverse, with each style of beer box typically featuring not just four basic colors but also several spot colors, such as gold and silver, which are all considered spot colors.

3. Die Cutting: This is a crucial step in the printing process. Accurate die cutting is essential; if the die cutting is not precise, it may result in misalignment, partial cuts, or incomplete cuts, all of which can affect subsequent processing.

4. Printing: Beer boxes are only printed with packaging paper; the lamination is not printed on, at most it is dyed. Since beer boxes are outer packaging boxes, the printing requirements for beer boxes are very high, and they are very sensitive to color discrepancies, ink spots, and misregistration, which can affect aesthetics.

5. Surface Treatment, the packaging paper of beer boxes usually requires surface treatment, commonly including glossy coating, matte coating, UV coating, glossy oil, and matte oil.

6. Mounting, typically, printed materials are mounted after being die-cut, but beer boxes are die-cut first, then mounted. This is because we want to avoid soiling the packaging paper and ensure the overall aesthetic appeal of the beer box. The mounting paper for beer boxes must be handcrafted to achieve a certain level of beauty.

7. Punch holes where necessary, and for those that don't require punching, simply wipe the surface glue. Then, the product is ready for packaging and delivery.
