不干胶标签质量怎么查看是否合格?

来源:http://www.shengfengyinshua.com/ 日期:2021-01-06 发布人:shengfeng 一、原质料的选择
1、 Selection of raw materials
选择原质料时,肯定要选用高质量、各项理化指标均合格的不干胶质料,而不要选用逾期或理化指标不稳固的产品。因为后者虽然价钱低,但由于这类质料质量不稳固,在各工序斲丧大,以致导致设置装备部署无法正常加工,在浪费了原质料的同时还浪费了大量的人力、物力,效果成品标签的加工成本并不肯定低,更为告急的是另有大概遭到客户退货,以致失去客户。
When selecting raw materials, we must choose high-quality self-adhesive materials with qualified physical and chemical indexes instead of products with overdue or unstable physical and chemical indexes. Although the price of the latter is low, due to the unstable quality of such materials and the large consumption in each process, the equipment deployment can not be processed normally. As a result, a lot of manpower and material resources are wasted while the raw materials are wasted. As a result, the processing cost of the finished product label is not low. What's more urgent is that it may be returned by the customer, resulting in the loss of the customer.
原质料的选择应从以下两个方面思量。
The selection of raw materials should be considered from the following two aspects.
1.不干胶质料的印刷和加工特性
1. Printing and processing characteristics of self-adhesive materials
①面材的外貌毫光和颜色的同等性、密度的匀称性
① The uniformity of appearance, color and density
达些指标决定了不干胶质料吸墨的匀称性,还决定着同批标签印品的色差。面材的涂层强度决定了印刷时是否会孕育发生大量纸粉,也是决定印刷质量的告急指标。

To achieve these indicators determines the uniformity of ink absorption of self-adhesive materials, but also determines the color difference of the same batch of label printing products. The coating strength of surface material determines whether a large amount of paper powder will be produced during printing, and it is also an urgent index to determine the printing quality.
②底纸、面材厚度的匀称性和强度指示
② Thickness uniformity and strength indication of base paper and surface material
这些指标不但关连到印刷性能,照旧决定模切匀称性和排废时速度与纸边断裂的告急指标。要是这些指标太低,标签机就无*速生产。
These indicators are not only related to the printing performance, but also determine the die-cutting uniformity and waste discharge speed and edge fracture. If these indicators are too low, the label machine will have no * speed production.
③质料的平整度或复卷张力的匀称性
③ Evenness of material or evenness of rewinding tension
无论是单张印刷照旧卷筒印刷,质料的平整度都决定了印刷时是否能准确输纸、运行和套准、收纸。搪塞卷筒质料,复卷张力会对卷筒质料端面的平整度、是否出现渗胶、能否准确套准起告急的作用。
Whether it is sheet fed printing or web printing, the flatness of the material determines whether the paper can be accurately fed, run, register and received. The rewinding tension will have an urgent effect on the flatness of the end face of the reel material, whether there is glue leakage, and whether it can be accurately set.
④粘合剂、硅油涂布的匀称性和准确的涂布量
④ Adhesive, silicone oil coating uniformity and accurate coating amount
这些指标直按影响标签同底纸间的剥离力(离型力),而剥离力的大小又直接影响模切排废和呆板的速度,剥离力还决定了标签的出标状态,即应用情况。另外,涂胶量的大小还会影响质料端面的渗胶状态。以是,购置不干胶质料时要认真检验,选择那些涂胶量和涂硅量符合的质料。
These indicators directly affect the stripping force (release force) between the label and the backing paper, and the size of the stripping force directly affects the speed of die-cutting waste discharge and mechanical, and the stripping force also determines the label's out state, that is, the application situation. In addition, the amount of glue will also affect the end of the material infiltration state. Therefore, the purchase of self-adhesive materials should be carefully tested, choose those coating amount and silicon coating amount of material.
