          激光標簽制作廠家-標簽覆膜有哪些方法?

          來源:http://www.apersianrug.com/ 日期:2020-09-25 發布人:shengfeng 1、單張紙覆膜
          1. Sheet paper lamination
          根據覆膜設備的功能和復合膜的特點,單張紙不干膠標簽有兩種覆膜方式:
          According to the function of laminating equipment and the characteristics of composite film, there are two laminating methods for sheet fed self-adhesive label
          即涂復合——在覆膜機上完成。復合過程是:首先,在卷筒BOPP薄膜表面涂布粘合劑,并經烘干裝置使粘合劑中的溶劑揮發,然后在復合工位上將單張紙同卷筒膜復合,在熱滾筒擠壓下二者成為一體,完成覆膜加工。
          Instant coating and lamination - completed on laminating machine. The compounding process is as follows: firstly, the adhesive is coated on the surface of BOPP film on the reel, and the solvent in the adhesive is volatilized by the drying device, and then the sheet paper is compounded with the roll film at the laminating station, and the two become one under the hot roller extrusion to complete the laminating process.
          預涂膜復合——復合膜表面預先涂有粘合劑,有熱熔膠型和壓敏型兩種薄膜。覆膜機上裝有加熱壓印滾筒,覆膜時預涂膜同單張紙接觸,在熱壓滾筒的作用下,粘合劑熔化,使薄膜同紙粘合成為一體。若使用壓敏型復合膜可關掉加熱電源,只靠壓力復合。
          Pre coating lamination - the surface of the composite film is pre coated with adhesive, including hot-melt adhesive film and pressure-sensitive film. The laminating machine is equipped with a heating embossing roller. When laminating, the pre coating film contacts with the sheet paper. Under the action of the hot pressing roller, the adhesive melts, making the film and the paper bond together. If the pressure-sensitive composite film is used, the heating power can be turned off and only pressure lamination can be used.

          2、卷筒紙覆膜
          2. Web lamination
          根據設備的不同,卷筒紙覆膜可分為:
          According to different equipment, web lamination can be divided into:
          有底紙復合膜復合——在標簽機上進行,使用有底紙的專用復合膜,在復合裝置的作用下覆膜。這是一種傳統的覆膜方式。近年來已被使用無底紙復合膜的工藝所代替。
          Composite film lamination with backing paper -- it is carried out on the label machine, using the special composite film with backing paper, and laminating under the action of the laminating device. This is a traditional way of film covering. In recent years, it has been replaced by the technology of bottomless paper composite film.
          無底紙復合膜復合——在標簽機上進行,覆膜原理同有底紙復合膜復合工藝基本相向。無底紙膜靠自身材料的表面光滑度(表面張力)復卷后代替底紙,粘合劑同其表面粘合后,還可剝離,且不殘留膠跡。無底紙膜所用的材料為低表面張力的BOPP薄膜。無底紙膜覆膜成本低,是目前使用更廣泛的一種覆膜材料。
          The lamination of paperless composite film is carried out on the label machine, and the principle of lamination is basically the same as that of the laminating process with backing paper. After rewinding by the surface smoothness (surface tension) of its own material, the backing paper can be replaced by the backing paper. After the adhesive is bonded with its surface, it can be peeled off without residual adhesive traces. BOPP film with low surface tension is used for bottomless paper film. Bottomless paper film is one of the most widely used laminating materials with low cost.
          干法覆膜——在覆膜機或凹印機上進行,主要用于薄膜材料的覆膜。卷筒材料干法覆膜適合大批量的標簽產品,覆膜質量好,成本低。卷簡標簽覆膜后一般還要在加工機上進行模切、排廢等二次加工,如某些電池標簽和酒類標簽。
          Dry laminating - on laminating machine or gravure press, mainly used for laminating film materials. Drum material dry lamination is suitable for large quantities of label products with good quality and low cost. After the film covering, the roll label is usually processed by die cutting and waste discharge on the processing machine, such as some battery labels and wine labels.
          UV覆膜工藝——國外工藝,主要應用在有UV干燥裝置的機組型輪轉標簽機上。工藝原理是:覆膜材料表面由普通印刷單元首先印上UV粘合劑,粘合劑經UV干燥裝置固化后,成為壓敏膠。而后將普通BOPP薄膜(一般復合面已經電暈處理)在覆膜工位同卷筒材料復合,完成覆膜加工。UV覆膜成本低,復合膜張力變化小,不需專用薄膜,適合高速生產。UV覆膜是一項有發展前途的工藝,目前在歐美發達國家已經應用。
          UV coating technology - foreign process, mainly used in the unit type rotary label machine with UV drying device. The principle of the process is: the surface of the laminating material is first printed with UV adhesive on the surface of the common printing unit, and the adhesive is solidified by the UV drying device to become pressure-sensitive adhesive. After that, the common BOPP film (the general composite surface has been corona treated) is compounded with the reel material in the laminating station to complete the laminating process. The cost of UV coating is low, the tension change of composite film is small, no special film is needed, and it is suitable for high-speed production. UV coating is a promising technology, which has been applied in developed countries in Europe and America.
