Knowledge of Beer Boxes
Beer boxes are paper boxes made by pressing cardboard into shape using a die-cutting machine and then bonding them together, primarily composed of corrugated cardboard.
Beer boxes come in various types such as bottom-latching, double-slot, and airplane-style boxes. They feature lightweight design, ease of transportation and storage, and cost-effectiveness. Each type is specifically used for different product packaging based on their unique characteristics.
Manufacturing Process
1. Paper selection: The common packaging paper for beer boxes is typically made of double copper or matte copper paper, with a grammage of around 128G, 105G, or 157G. Rarely do beer box packaging papers exceed 200G, as thicker paper can lead to bubbles during lamination and give the box a dull appearance. The lamination paper is chosen based on the customer's requirements and is commonly referred to as gray board paper or gray card paper.
2. Die Cutting: Current beer box designs emphasize aesthetic appeal, so the colors used in the die-cutting 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 crucial process in printing. Accuracy is essential for precise die-making; otherwise, inaccuracies in die-cutting, uneven cuts, or breaks in the die can affect subsequent processing.
4. Printing: Beer boxes are only printed with packaging paper, as the lamination is not printed. At most, it's just dyed. Since beer boxes are outer packaging boxes, the printing requirements are very high, and it is particularly important to avoid aesthetic flaws such as color discrepancies, ink spots, and off-registration.
5. Surface Treatment - The packaging paper for beer boxes usually requires surface treatment, commonly including 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, being die-cut first and 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. Punch the holes where necessary, and for those that don't require punching, clean the surface glue. After that, the goods can be packed and delivered.
