Everyone is familiar with the handbag. It is widely used in the commodity packaging of clothing, food, shoes, gifts, tobacco and wine industries. Due to the needs of the use function and design, the printing and manufacturing process of the handbag has to go through a certain process. Today, we will briefly introduce it.

首先是必须经历的手提袋的设计环节，很多手提袋是企业形象和商品广告策略的延伸，因此选用的材料、装饰的工艺和表现的形式都与纸袋的用途和功效密不可分。设计师应考虑纸张材料的经济利用，工艺设计的合理性。为了生产和品质管控，设计时制作一套完整清晰的作业工程图必不可少，多数情况下产品还需要经过打样确认。设计中的打样既是工艺的验证，也是客户确认的依据、生产的标本。

The first is the design link of the handbag that must be experienced. Many handbags are the extension of corporate image and commodity advertising strategy. Therefore, the selected materials, decoration technology and forms of expression are inseparable from the use and efficacy of paper bags. Designers should consider the economic utilization of paper materials and the rationality of process design. In order to control the production and quality, it is necessary to make a complete set of clear operation engineering drawings during the design, and in most cases, the products need to be proofed and confirmed. The proofing in the design is not only the process verification, but also the basis of customer confirmation and production samples.

设计完之后就是手提袋的印刷了，手提袋的印刷设计与一般印刷品不同，专色、满版较多，用墨量大、颜色鲜艳。所以它的印刷工艺也与其它产品要求有所不同。印刷操作者要特别注意水墨平衡的控制，设备调整的状态要好，否则容易发生水墨起杠，颜色的色差问题。

After the design, it is the printing of the handbag. The printing design of the handbag is different from that of the general printed matter. There are more spot colors and full plates, and the ink consumption is large and the color is bright. So its printing process is different from other products. The printing operator should pay special attention to the control of ink and water balance, and the equipment should be adjusted in a good state. Otherwise, it is easy to cause ink bar and color difference.

印刷完成之后要对印刷后的产品进行覆膜，覆膜一般有预涂和即涂两种工艺，近年来覆膜工艺的环保性也有了较大的提高。覆膜也对增加手提袋色彩的浓度、提高产品的防水避污性能有着重要的作用。

After printing, the printed products should be covered with film. Generally, there are two processes of precoating and immediate coating. In recent years, the environmental protection of laminating process has been greatly improved. The film mulching also plays an important role in increasing the color concentration of the bag and improving the waterproof and anti fouling performance of the product.

覆膜完成之后就是对手提袋的模切加工和糊盒了，其中模切的质量直接影响纸袋成型品质和手工糊制效率。糊盒主要依赖于手工完成，是整个纸袋工艺流程中效率低的一个环节。经手工糊制完成的手提纸袋基本已经成型，有些手提纸袋还有后一道工序——冲孔、穿绳等作业，从而完成手提纸袋的成型包装。

After the completion of lamination is the hand bag die-cutting processing and paste box, in which the quality of die-cutting directly affects the paper bag forming quality and manual paste efficiency. Paste box mainly depends on manual completion, which is the lowest efficiency link in the whole paper bag process. The hand-held paper bags made by hand have been basically formed. Some hand-held paper bags have the last process - punching, threading and other operations, so as to complete the forming and packaging of the hand-held paper bags.
