Soft bag shaped typesetting process

A, typesetting typesetting process for special-shaped bag production preparation period, must fully consider the follow-up production request at this time, in the design of packaging film printing surface, especially pay attention to the scrap allowance of control, out of the bag the choice of direction and control of production and the number of columns. These aspects, improper design will bring problems to the production of subsequent special-shaped bag, even can't normal production. 1. Scrap allowance of control in order to reduce the production cost, should make full use of bag with the membrane material, so in the design of special-shaped bag printed, designers often try to bridge the gap between the bag. At the same time, in die cutting special-shaped bag, if left blank between before and after the bag quantity is too little, after the die cutting waste rollers lateral connection easy to break, cause waste removal is difficult to collect on both sides, causing waste removal tension on either side of the imbalance, cause abnormity bag die cutting machining process cannot run smoothly. According to different membrane materials and bag type materials, special-shaped bag waste edge allowance should be 5 mm or more than 5 mm. Therefore, bag making direction, in order to convenient for mass production. Out of the bag and the choice of direction bag direction generally have horizontal and vertical two. Cross out means the special-shaped bag positive words and pattern on the left or right when the bag out of the first one way; Longitudinal out means the special-shaped bag positive words, pattern feet or head when bag come out the way first. Special-shaped bag production out of the bag when the choice of direction, the shape characteristics of special-shaped bag, be taken into account and its forming method, follow-up processing equipment, product quality requirements and other factors. And should be under the premise of meeting the production requirement, try to reduce the amount of waste edge membrane. If the incorrect direction out of the bag, will greatly influence the production efficiency, and even lead to can't production. As shown in figure 2 special-shaped self-supporting bag if choose & other; Cross out & throughout; That is a good way to die cutting forming at a time. Generally speaking, self-reliance abnormity bag or self-supporting zipper special-shaped bag should choose in both insert materials handling, for bag. At present, the domestic production of the structure of die cutting machine has been basically can satisfy the requirement of the conventional bag production, and through constant optimization design, the special-shaped bag automatic die-cutting machine can processing double self-supporting special-shaped bag or a three penguins bag, etc. 3. Production control of the number of columns as the mass of special-shaped bag production, in order to improve the efficiency of production, designers generally in typesetting will consider increasing the number of columns, namely in the layout when considering the number of lateral one-time can produce special-shaped bag, it is also a special bag layout of one of the key projects. According to the author of the experience gained in practical production, such as bag type size is not big, can choose multiple columns production, so that more conducive to subsequent die cutting scrap edge winding, in general, can choose the number of columns for 2 ~ 3 columns. And for larger size bag, due to its width size is larger, the horizontal die cutting, try to balance waste edge on both sides of the tension and the number of columns should be relatively small, usually is 1, otherwise, easy to make the membrane material in die cutting position offset and waste generation. When abnormity bag layout, the processing difficulty and the production efficiency, be taken into account to determine the appropriate production number of columns.
