Shrinkage label has become more and more popular, it is to double-digit annual percentage of rapid growth. Fetch such results, at least from two aspects of reason, one is the contraction labels can make full use of the vessel surface, for image and representation of the information and communication play a very good effect. On the other hand, container itself can be made for all the shape of the unique, from how to stick mark after restrictions, which can greatly enhance the shelves of packaging products appeal.
However, it is because of these special shape, to label materials and printing ink put forward higher request and challenges. In addition to processing without holes the bond film materials sexual problems, shrinkage label printing ink will deal with several other factors, in order to make it to gain better development, including deformation (cut, stratification, etc), and paste version, low COF (friction coefficient) and used in food and beverage packaging of low smell sex. And these requirements but also promote the printing material and the further development of the ink.
Suitable for specific materials
In data, PVC, PETG and OPS occupied most of the market shrink label. According to Siegwerk company PPL technical director ManuetRivas introduces division, among them, before both that account for 90% to 95% of the market share. Because each film has their surface characteristics, each film all need to adopt specific ink composition, in order to get the right performance.
In order to meet the needs of the changeable, JinYin provides a specialized company for each contraction thin materials and printing process design of ink solvent. In addition, the water-base printing ink of flexible printing business can after the PVC and PETG corona treatment on film by its CWS-2100 series of printing ink printing, and SICURA series ink may satisfy the demand of UV printing. In order to facilitate the people choose the ink, the company also launched a solvent ink AccessSleeve, this series ink applies to all film materials.
INX international printing ink company developed ShrinkPac series ink, and can be used in a variety of materials, it is applicable for various printing process, such as applicable to the gravure ShrinkPac, apply to the FlexoShrinkPac flexible printing. In the simplified and accelerate the turnover of living thing at the same time, our printing ink and solved the many shrinkage label printing business daily meet some of the other issues, to the multi-function direction
In printing ink supplier provide a series of products to meet a particular ink contraction of label printing at the same time, it is applicable for various shrinkage label materials are made rapid development of printing ink. Before, many ink are applied to a specific materials, and now, update the ink in the series of material presented the characteristics of multi-function, and this helps to reduce the printing machine washing time, reduce cross contamination, and to control the amount of ink.
XSYS company from a new progress is lexocureXSUV free radicals curing inks, it can provide 70% of shrinkage rate, it is applicable for various film materials, including PVC, OPS, OPP, PET and PETG, also can be used in table India and in print.
And Fuji lubricious li's Uvisleeve is another kind of UV flexible printing ink, the shrinkage process according to the properties of and design.
The company underscored Uvisleeve several main quality, such as low COF, low chemical smell, the biggest shrinkage rate, so as to facilitate the contraction of the label materials. In addition, they also offer high opacity white ink. The role of low COF mainly reflects in sealing (seaming) in the process, it allows set of standard in after sealing can be quickly through the labeling device.
In the design for the UV ink contraction label printing, UVitec company general manager BobWaddington points out, the choice of the resin and light initiator must consider the film contraction, won't scratch material, at the same time in the relatively cold environment has good performance, such as not distortions. UVitec company recently introduced a new UV shrinkage label printing ink series, improve the scratch resistant performance and the layered performance.
WaterInk technology the company not only provides water-based ink, and also provides UV ink that they could apply to the contraction of usually label printing. Add industry and commerce can use each of the best features of the ink satisfy it their individual needs, such as water ink economy, UV ink opacity or set of standard efficiency, etc.
