Beer Box Knowledge
A beer box is a cardboard box that is formed by pressing the paperboard through a die-cutting machine and then glued together, primarily made of corrugated cardboard.
Beer boxes come in various types such as the bottom-locked box, double-slot box, and airplane box, featuring lightweight, easy transportation and storage, and low cost. They are also applied to different product packaging based on their unique characteristics.
Manufacturing Process
1. Paper selection: Standard beer box wrapping paper is usually made from double copper or matte copper paper, with a grammage of 128G, 105G, or 157G. It's rare for beer box wrapping paper to exceed 200G, as thicker paper can cause bubbles in the finished beer box and give it a dull appearance. Laminating paper is chosen based on customer requirements and is commonly known as grey board or grey card paper.
2. Die-cutting: Modern beer boxes emphasize aesthetics, so the colors used in the die-cutting are diverse, with each style often featuring not just the four basic colors but also several spot colors, such as gold and silver, which are considered spot colors.
3. Perforating is a critical step in the printing process. Accurate perforation requires precise die cutting; otherwise, inaccuracies, misalignments, or incomplete perforations can affect subsequent processing.
4. Printing: Beer boxes are printed only with packaging paper, the lamination is not printed on, at most it's just dyed. Since beer boxes are outer packaging boxes, their printing requires a high level of craftsmanship and is very sensitive to color discrepancies, ink spots, and other defects that affect aesthetics.
5. Surface Treatment: The packaging paper for beer boxes usually requires surface treatment, common processes include 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 being die-cut. This is because we want 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.
