Knowledge of Beer Boxes
Beer boxes are paper boxes made by die-cutting and pressing cardboard into shape, with the main material being corrugated cardboard.
Beer boxes come in various types, such as bottom-latching, double-insertion, and airplane boxes, featuring lightweight, easy transportation and storage, and cost-effectiveness. Each type is used for different product packaging based on its unique characteristics.
Manufacturing Process
1. Paper selection: Standard beer box packaging is typically made with double copper or matte copper paper, with grammage usually at 128G, 105G, or 157G. Rarely do beer boxes use packaging over 200G, as thicker paper can lead to bubbles in the finished boxes and a dull appearance. The covering paper is selected based on customer requirements, commonly known as grey board or grey card paper.
2. Die-cutting: Current beer boxes emphasize aesthetics, so the colors used in production are diverse, often including not just the four basic colors but also several spot colors, such as gold and silver, which are considered spot colors.
3. Die-cutting is a critical step in the printing process. To ensure accuracy, the die must be precise. Inaccurate die-cutting, misalignment, or incomplete cuts can all affect subsequent processing.
4. Printing: Beer boxes are only printed with packaging paper, the wrapping paper 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 flawed prints that may affect aesthetics.
5. Surface Treatment - The packaging paper for beer boxes typically requires surface treatment, which commonly includes glossy lamination, matte lamination, UV coating, glossy varnish, and matte varnish.
6. Mounting: Typically, printed materials are mounted after being die-cut, but beer boxes are the opposite—they are die-cut first, then mounted. This is to avoid 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. Drilling: Drill where necessary, and for those that don't require drilling, wipe the surface adhesive. Then, the goods are ready for packaging and shipment.
