Beer Box Knowledge
Beer boxes are paper boxes made by pressing and shaping cardboard through a die-cutting machine and then bonding them together, primarily composed of corrugated cardboard.
Beer boxes come in various types, including bottom-latching, double-insertion, and airplane boxes, featuring lightweight design, easy transportation and storage, and cost-effectiveness. They are each used for different product packaging based on their 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 box wrapping papers exceed 200G, as thicker wrapping paper can cause bubbles in the finished beer box and give it an unattractive, rigid appearance. The lining paper is chosen based on customer requirements, commonly referred to as gray board or gray card paper.
2. Die cutting, the current beer boxes emphasize beautiful appearance, so the colors of the die cuts are diverse. Generally, a style of beer box not only has 4 basic colors but also several special colors, such as gold and silver, which are all special colors.
3. Perforation is a crucial step in the printing process. Accurate perforation requires precise die cutting; otherwise, inaccuracies, misalignment, or incomplete perforation can affect subsequent processing.
4. Printing: Beer boxes are printed using only packaging paper, with no lamination, which is not printed either; at most, it's just dyed. Since beer boxes are outer packaging boxes, the printing requirements for them are very high, and color discrepancies, ink spots, and misregistration are strictly avoided as they can negatively impact aesthetics.
5. Surface Treatment: The packaging paper for beer boxes usually 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 – mounted after die-cutting. This is to avoid damaging the packaging paper and to ensure the overall aesthetics of the beer box, which demands handcrafted mounting papers to achieve a certain level of beauty.
7. Punch holes where necessary, and for those that don't require punching, wipe the surface glue. Then, the goods are ready for packaging and shipment.
