The beverage giants have vied for beverage market, unity, Huiyuan, Master Kang, Pepsi, Coca-Cola, farmer spring, Robust, silver herons were all across the board to launch its own new types of beverages. Such a hot beverage industry, for beverage packaging, highlighting the brand image as a natural benefit of the heat shrink labels.
Shrink labels are part of the label market, applied to heat shrink packaging, are now undergoing rapid growth among the market share expanded. Annual growth rate is expected to be maintained at around 15%, far exceeding the general label of the annual growth rate of around 5% of the market, huge potential for development has become the industry's largest labels highlights.
As the name suggests, is a heat shrinkable label uses special ink printed on plastic film or plastic film tube labels, in the labeling process, when the heat (70 ℃ or so), the shrink-label will soon be along the outer container contour contraction, close to the surface of the container. Such labels can not be considered in the label area of new products, mostly from the 20th century large-scale applications since the early 90s, but it has to meet the unique packaging of goods, and therefore, in the packaging market, is most welcome. Shrink film packaging and shrink-label loved by people another reason is its image with a three-dimensional feeling, giving to the rich imagination and attracted many customers and consumer interest and, therefore, opened up a broad market outlets.
Second, the characteristics of heat shrinkable label
1. Shrink Label Benefits
① heat shrinkable film is highly transparent, so label bright color and better luster.
② the large-scale production, is an independent production label.
③ heat shrinkable film contraction close to merchandise, packaging, compact and can show appearance of goods, packaged goods aesthetic. , Hangzhou Wahaha Group, such as milk dolls Shuangwai Wai probiotic fermented yogurt on the use of heat shrink labels. Form a unique set of special-shaped bottle bottle designed to fit the pattern, abundant charm, the first time be able to capture hearts and minds of children.
④ shrink-wear-resistance is good, but also has a high strength to ensure that bear the weight of the contents. Films are printed inside the printing (graphic kit is in the membrane), may play a role in protection of imprinting, and labeling and better wear resistance.
⑤ Shrink packaging technology and equipment is relatively simple, seal is good, no need to use adhesive labels when labeling.
⑥ shape of beverage containers are now unique, personalized designs increasing heat shrinkable film label to clearly show the outer surface of a beverage container profile.

Yinlu majority of products have used shrink-label.
⑦ shrink film as the label to save forest resources, reduce costs, health, easy to use.
2. Heat shrinkable film label shortcomings
① to consider the graphic image of the shrinkage rate and shrinkage film shrinkage, as can be accurately reproduced.
② in the heat-shrink label printing ink used must also have a certain shrinkage, can accurately reproduce the graphics.
③ As the heat-shrink label printing process must be in contraction, while the bar code can be read only accurate reproduction, it must go through rigorous design and printing quality control, otherwise the pattern will cause shrinkage deformation of inferior quality or can not read barcode .
④ the majority of heat shrinkable film printability is not very good, the need for pre-press pre-processing.
