Knowledge of Beer Cases

Beer boxes are paper boxes made by pressing and shaping cardboard through a creasing machine and then bonding them together, primarily made of corrugated cardboard.

The beer boxes come in various types such as bottom-clip boxes, double-insert boxes, and airplane boxes. They are characterized by their lightweight nature, ease of transportation and storage, and cost-effectiveness. Each type is suited for different product packaging based on its unique features.

　　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. It's rare for beer box wrapping paper to exceed 200G, as thicker paper can lead to bubbles in the finished box and a dull appearance. The wrapping paper is selected based on the customer's requirements, commonly known as gray board paper or gray card paper.

2. Die Cutting: Current beer box designs emphasize aesthetic beauty, thus the colors of the die-cuts are diverse, with a single style of beer box typically featuring not only 4 basic colors but also several spot colors, such as gold and silver, which are considered spot colors.

3. Die-cutting is a crucial process in printing, and accuracy is paramount. The dies must be precisely made; otherwise, inaccuracies in die-cutting, such as misalignment or failure to cut through, can affect subsequent processing.

4. Printing: Beer boxes are only printed with packaging paper, the lamination is not printed, at most it's just 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 worn-out plates, which can affect aesthetics.

5. Surface Treatment: The packaging paper for beer boxes usually requires surface treatment, common methods include glossy coating, matte coating, UV coating, glossy varnish, and matte varnish.

6. Mounting: Generally, printed materials are mounted after being die-cut, but beer boxes are an exception—they are die-cut first, then mounted. This is to prevent damaging the packaging paper and because beer boxes emphasize overall aesthetics. The mounting paper for beer boxes must be handcrafted to achieve a certain level of beauty.

7. Punching: Punch where necessary, and for those areas not to be punched, wipe the surface adhesive. Then, the goods are ready for packaging and shipment.
