彩色印刷采用不干胶覆膜的加工方式
作者:admin 来源:http://www.sdhzyw.com 发布时间:2017-12-27 14:44:59 浏览次数:279
不干胶标签的覆膜一般都是在纸张类不干胶材料上复合透明的BOPP薄膜,可达到保护图纹、防水、防腐、增加标签立体感的目的。其它类型的薄膜,如PET、PVC也可作为复合膜,但应用不普遍。纸张类卷筒材料覆膜由于成本高,已逐步被UV上光工艺代替。
The laminating film of self-adhesive labels is generally made of transparent BOPP film on paper type self-adhesive materials, which can achieve the purpose of protecting graphics, waterproofing, anti-corrosion and increasing the sense of labels. Other types of thin films, such as PET and PVC, can also be used as composite membranes, but they are not widely used. Because of the high cost, the paper type roller material has been replaced by the UV polishing process.
不干胶标签根据原材料的印刷加工方式,分为单张纸覆膜和卷筒材料覆膜。单张纸在覆膜机上覆膜。卷筒材料则在标签机的复合工位或专用的复合机上复合。
According to the printing process of raw materials, the sticker label can be divided into single sheet film mulching and reel material covering. The sheet of paper is coated on the film mulching machine. The reel material is compounded on the compound work position of the label machine or the special compound machine.

根据覆膜设备的功能和复合膜的特点,单张纸不干胶标签有两种覆膜方式:

According to the function of the film covering equipment and the characteristics of the composite film, there are two kinds of film covering methods for the single paper sticker label:
即涂复合--在覆膜机上完成。复合过程是:首先,在卷筒BOPP薄膜表面涂布粘合剂,并经烘干装置使粘合剂中的溶剂挥发,然后在复合工位上将单张纸同卷筒膜复合,在热滚筒挤压下二者成为一体,完成覆膜加工。
That is, the coating compound is done on the film mulching machine. The composite process is: first, the adhesive is coated on the surface of the drum BOPP film, and the solvent in the adhesive is volatilized by the drying device. Then the sheet is combined with the drum membrane in the compound position, and the two parts are integrated into the whole process to finish the laminating process under the hot roller extrusion.
预涂膜复合--复合膜表面预先涂有粘合剂,有热熔胶型和压敏型两种薄膜。覆膜机上装有加热压印滚筒,覆膜时预涂膜同单张纸接触,在热压滚筒的作用下,粘合剂熔化,使薄膜同纸化粘合成为一体。若使用压敏型复合膜可关掉加热电源,只靠压力复合。
Pre coating composite - the surface of the composite film is coated with adhesive in advance, and there are two kinds of film, hot melt adhesive and pressure sensitive type. The laminating machine is equipped with heating imprint cylinder. When the film is coated, the pre coating film is contacted with the sheet paper. Under the action of the hot roller, the adhesive is melted and the film is bonded with the paper. If the pressure sensitive composite membrane is used, the heating power can be turned off, and the pressure is combined only.
有底纸复合膜复合--在标签机上进行,使用有底纸的专用复合膜,在复合装置的作用下覆膜。这是一种传统的覆膜方式。近年来已被使用无底纸复合膜的工艺所代替。
Subleveling paper composite film - in label machine, using special composite film subleveling paper, coated in the composite device under the action of. This is a traditional way of film mulching. In recent years, the process of using a bottomless composite film has been replaced.
无底纸复合膜复合--在标签机上进行,覆膜原理同有底纸复合膜复合工艺基本相向。无底纸膜靠自身材料的表面光滑度(表面张力)复卷后代替底纸,粘合剂同其表面粘合后,还可剥离,且不残留胶迹。无底纸膜所用的材料为低表面张力的BOPP薄膜。无底纸膜覆膜成本低,是目前使用更广泛的一种覆膜材料。
Linerless composite film -- in label machine, laminating principle with subleveling paper composite film process basic directions. The bottomless film is replaced by the surface smoothness (surface tension) of its own material instead of the base paper. After bonding the adhesive with its surface, it can also be stripped without leaving any traces of glue. The material used in a paper free film is a BOPP film with low surface tension. The low cost of the film mulching is the most widely used film covering material at present.
