不干胶标签翘起来你知道是为什么吗?

来源:http://www.shengfengyinshua.com/ 日期:2019-01-03 发布人:admin 如何解决不干胶标签翘起来问题
How to solve the problem of sticker sticking up
1、胶水粘性太弱:应挑选适合的胶水材料;
1. Glue viscosity is too weak: suitable glue material should be selected;
2、贴标机压轮压力不敷:缘由宽和决计划如上;
2. The pressure of labeling press is insufficient: the reason is wide and the plan is as above.
3、不干胶标签面材:挑选标签面材时,应该思索贴标物体是平面照样曲面,是大直径照样小直径,是单一曲面照样球面,是刚体照样可紧缩变形的,这些目标同面材的挑选有直接的联系。
3. Self-adhesive label fabrics: When selecting label fabrics, we should consider that the labeled objects are plane-like surfaces, large-diameter or small-diameter, single-surface or sphere, rigid-body can be deformed and compacted, and these objectives are directly related to the selection of surface materials.
软质的瓶体应该挑选娇嫩的材料如PE、PVC、未经拉伸的PP以及PE和PP组成的材料。硬质瓶体能够思索选用PET、BOPP、PS材料;
Soft bottles should be made of delicate materials such as PE, PVC, non-stretched P P, PE and P P. Hard bottle body can choose PET, BOPP, PS materials.
4、粘胶剂挑选欠妥:挑选不干胶粘合剂时,起首要断定所制造的不干胶标签所需的粘合剂是永世性照样可移除性的,是一次粘贴照样可重贴的,以及产品对个干胶标签粘合剂的化学特征能否有特殊要求等。
4. Insufficient selection of adhesives: When selecting adhesives, the first thing to do is to determine whether the adhesives needed for the labels are permanent or removable, whether they can be re-pasted at one time, and whether the products have special requirements for the chemical characteristics of a dry adhesives label.
例如在大曲度表面(直径小于2cm的圆形基材)贴标时,面材不宜选用厚重或原料硬的纸质材料(如镜面铜版纸),应选用薄膜或薄软的纸质材料和初始粘性较高的粘胶剂;关于需求进行热灌装的容器,不干胶材料面材宜选用薄膜原料和初始粘度好的粘胶剂;
For example, when labeling large curvature surface (circular base material with diameter less than 2cm), it is not appropriate to choose thick or hard paper material (such as mirror copperplate paper), thin or soft paper material and adhesive with high initial viscosity; for container which needs hot filling, non-drying surface material should choose film material and adhesive with good initial viscosity;
5、覆膜张力控制欠安:经精确覆膜的标签从底纸上揭离后平坦,不卷曲、贴标后标签可坚持较好的跟随性;覆膜张力过紧的标签从底纸上揭离后,标签反翘,引起贴标后容易出现标签边缘脱胶、起翘的景象;
5. Insufficient tension control of film-covering: after exact Film-covering label is removed from the base paper, it is flat, without curling and labeling, the label can adhere to better follow; when the label with too tight Film-covering tension is removed from the base paper, the label will turn upside down, which will cause the label edge to degum and warp easily after labeling.
6、瓶体外形规划不合理:合理的规划应该是瓶体恤标局限内表面平坦(首要是在扁圆形瓶体规划上),然则假设贴标局限内表面呈部分球形,在运用纸质标签贴标时贴标较大面积大,贴标后下端容易两边起皱。
6. The shape planning of bottle body is unreasonable: the reasonable planning should be that the inner surface of bottle body is flat (mainly in flat circular bottle body planning), but assume that the inner surface of bottle body is partially spherical. When using paper labeling, the labeling area is large, and the lower end of bottle body is easy to wrinkle on both sides.
