Beer Box Knowledge
Beer boxes are paper boxes made by pressing and shaping cardboard through a creasing machine, and they are mainly composed of corrugated cardboard.
Beer boxes come in various types such as snap-bottom boxes, double-slot boxes, 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 wrapping paper is typically made from double copper or matte copper paper, with a weight of around 128G, 105G, or 157G. It's rare for beer box wrapping paper to exceed 200G, as thicker paper can cause bubbles during lamination and may appear dull in appearance. The lamination paper is chosen based on customer requirements, commonly known as gray board or gray card paper.
2. Plate-making: Today's beer boxes emphasize aesthetic appeal, so the colors used in the plates are diverse. Typically, a style of beer box not only features 4 basic colors but also includes several spot colors, such as gold and silver, which are considered spot colors.
3. Die Cutting is a crucial step in the printing process. Accuracy is key, as precise die-making is necessary. Inaccurate die cutting, misalignment, or incomplete cuts can all affect subsequent processing.
4. Printing: Beer boxes are only printed with packaging paper; the lamination is not printed, at most just dyed. Since beer boxes are outer packaging boxes, the printing requirements are very high, and color discrepancies, ink spots, and off-press errors are highly undesirable as they affect aesthetics.
5. Surface Treatment: The packaging paper for beer boxes usually requires surface treatment, common methods include glossy lamination, matte lamination, 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 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. Punch holes where necessary, and for those that don't require punching, wipe the surface adhesive. Then, the goods are ready for packaging and shipment.
