Aluminum crystal label and preparation method thereof

Abstract

The invention relates to the technical field of aluminum crystal labels, in particular to an aluminum crystal label and a preparation method thereof. The aluminum crystal label comprises a gloss oil layer, a concave-convex printing layer, an aluminum-plated paper layer and a bottom coating from top to bottom. The aluminum-plated paper layer comprises an aluminum-plated PET layer, a gluing layer, abase paper layer and a back coating from top to bottom. The aluminum-free surface of the aluminum-plated PET layer is bonded with the base paper layer through the gluing layer; the aluminum-plated PET layer is a bidirectional heat-shrinkable PET vacuum aluminum-plated film; the shrinkage rate of the bidirectional heat-shrinkable PET vacuum aluminum-plated film is 30-40% in the longitudinal direction and 55-80% in the transverse direction at the temperature of 50-70 DEG C. The aluminum crystal label has advantages of paper product labels and advantages of plastic labels. After the label is printed, the label has the single-label continuous labeling function of the paper labels, a labeling machine does not need to be replaced, and new and old products can be interchanged on the assembly line labeling machine. After labeling, bubbling and wrinkling are avoided, label grabbing marks do not appear, and the aluminum crystal label is a medium-and-high-end label and is particularly suitable for beer companies in the southern humid climate.

Description

technical field [0001] The invention relates to the technical field of aluminum crystal labels, in particular to an aluminum crystal label and a preparation method thereof. Background technique [0002] The processing space of beer manufacturers is relatively large, and the temperature and humidity of the production site cannot be guaranteed. Especially in the rainy season, the outdoor and indoor temperature and humidity are consistent, so it is easy to bubble after labeling, resulting in uneven labeling and defects. Beer is sold and stored in a variety of ways, including plastic baskets and packing boxes. Generally, the warehouses where beer is stored are airtight and the temperature and humidity control is relatively backward. Beer labels are easy to wrinkle after absorbing moisture, and the appearance and image of the label are damaged. Relatively large; restaurants, bars, and families who like to drink cold beer will put it in the freezer or put it directly into ice wate...

[0002] The processing space of beer manufacturers is relatively large, and the temperature and humidity of the production site cannot be guaranteed. Especially in the rainy season, the outdoor and indoor temperature and humidity are consistent, so it is easy to bubble after labeling, resulting in uneven labeling and defects.

Beer is sold and stored in a variety of ways, including plastic baskets and packing boxes. Generally, the warehouses where beer is stored are airtight and the temperature and humidity control is relatively backward. Beer labels are easy to wrinkle after absorbing moisture, and the appearance and image of the label are damaged. Relatively large; restaurants, bars, and families who like to drink cold beer will put it in the freezer or put it directly into ice water to cool down to achieve a cool pleasure. The label on the beer taken out of the freezer will be wrinkled and marked. Obviously, when taken out of the ice water, the light ones are marked with scratches and wrinkles are particularly obvious, and the serious ones appear to be dropped through the extension of the stretched marks, and the appearance quality is seriously damaged.

[0003] The three problems of bubbling, wrinkling, and palm printing have always existed on beer labels. In the early years, most of the Chinese beer industry took the low-end route, and the attention of drinking and selling wine was relatively weak. The requirements for counterfeiting and appearance quality are also constantly increasing. Therefore, the three persistent problems of bubbling, wrinkling, and palm printing on the beer label are fatal injuries that damage the appearance and must be rectified. The earliest international brands used PET as the label material to process it into a pressure-sensitive product. Glue products pasted on beer bottles did solve these three major problems, but new problems also emerged, 1. The price is relatively high; 2. Labeling is relatively slow
