Single plastic thin film label

Abstract

The invention discloses a single plastic thin film label, and belongs to the technical field of labels. By improving the formula of moisture-absorbing paint, a moisture-absorbing coating obtained by drying the moisture-absorbing paint is used for adsorbing ammonia gas and organic amine released by an adhesive and water in the environment, and the label is good in drying effect and firm in attaching; meanwhile, the label has excellent damp-proof and waterproof performance and can be iced for a long time; the label has extremely high strength and is not affected by transportation and storage; the label is excellent in color and luster and suitable for being automatically attached at a high speed and meets the various requirements for the printing process and innovation.

Description

technical field [0001] The invention belongs to the technical field of labels, and in particular relates to a single plastic film label. Background technique [0002] With the development of the commodity economy, the added value of the label is gradually increasing. It not only increases the branding of the product, but also reflects the grade and cultural taste of the product. Therefore, the design style of the label is gradually diversified. Taking beer labels as an example, at present, its printing materials mainly include paper labels (including coated paper, wet strength paper, aluminized paper, laser paper, etc.), aluminum foil and plastic film labels. [0003] Among them, the performance indicators such as water content, curling property, and back water absorption of paper labels directly affect the normal printing and labeling smoothness of beer labels. In addition, paper labels use paper as the base material, and papermaking pollution is serious. In aluminum foil...

Problems solved by technology

[0004] At present, plastic film labels, especially single-sheet plastic film labels, are mostly provided with a primer adhesive layer on the bottom of the label, and are bonded through the primer adhesive layer and the adhesive brushed on the bottle body. Due to the release of glue in the adhesive Ammonia or organic amines are prone to produce bubbles, resulting in blistering on the label and unsatisfactory labeling effect

Moreover, the cost of the primer adhesive layer is relatively high, it is difficult to degrade, and it will cause secondary pollution to the environment

In addition, when manufacturers recycle bottles and reuse them, quality problems such as residual glue from washing bottles often occur, which not only affects the use of secondary bottle stickers, but also increases the difficulty of operation, and the process is relatively complicated, with low output rate and high cost.

[0005] At the same time, generally beer, food, beverages, etc. are labeled on glass, plastic, and metal substrates. Because they are often in a cold environment, the humidity in the labeling environment is high, and moisture enters. The traditional label using the primer adhesive layer, due to The label is airtight, and it is difficult for wet water vapor to escape, and it is easy to generate air bubbles on the label
