1. Back-sealed bag: the arrangement of patterns is required. Trademark, product name, net content, bar code and other important pictures. Should not be too close to the heat sealing edge, so as not to seal the pattern after heat sealing. The pictures and texts in front can go into the back, but the patterns in the back can't go into the front. The typesetting direction and printing direction must be consistent with the direction of heat sealing edge, and the front and back pictures and texts are generally placed in the center of the unit size.
2. Pillow bags: There are three types: standard pillow bags, unequal pillow bags and side pillow bags. Side-sealed pillow bags are divided into non-heat-sealed edges, single-sided heat-sealed edges and double-sided heat-sealed edges. Requirements for pattern position arrangement; Trademark, product name, net content, bar code and other important graphics and texts. Not too close to the heat sealing edge, so as not to seal the pattern after heat sealing; The front, side and back patterns are generally placed in the center of their respective unit sizes; The front and back patterns are generally arranged to enter the side. Two side patterns must not enter the front and back, if the side graphics enter, it will affect the appearance; The typesetting direction and printing direction should be consistent with the heat sealing edge. The contents of the front and back patterns are the same or the back pattern is a whole. After heat sealing, the back pattern should be seamless, that is to say, the front size of the pillow bag is larger than the back size.
3. Four sealed bags: Four sealed bags are divided into five types: standard four sealed bags, three sealed bags, self-standing bags, zipper bags and single-sided aluminized bags. (1) standard four-sealed bag. When the heat sealing edge is transparent, the front graphic is generally slightly larger than the back graphic, and the back graphic must not be larger than the front graphic, so that the front graphic behind the paper bag can block the back. (2) sealing on three sides. There is no heat sealing edge between the front and back, which is mostly used for inner packaging bags. Generally, the back is illuminated, and the front and back of typesetting must be side by side. (3) Self-supporting bag: The typesetting is similar to the standard four-sealed bag. It must be arranged head-to-head or tail-to-tail, that is, it must be arranged horizontally, so as to add pillow bottom material to the bag bottom during cutting, which not only ensures that the direction of pillow bottom material is consistent with the printing direction. When two groups of units are placed horizontally, there must be transparency between the two groups of units. (4) Zipper bag: The typesetting is similar to the standard four-sealed bag, and it must be arranged head-to-head or tail-to-tail, that is, it must be arranged horizontally, so as to facilitate the zipper on the top of the bag when cutting, that is, to ensure that the zipper direction is the same as the printing direction. When two groups of units are placed horizontally, there must be transparency between the two groups of units. (5) Single-sided aluminized adhesive tape: also known as yin-yang bag, generally the front is not aluminized and the back is aluminized. For example, when the front and back are crosscut, the front and back should be arranged head to head, and transparency is required between the front and back. If the background color of the pattern is the edge, the carving should be widened. When how many units are arranged horizontally, front and back, front and back, back and back must generally be side by side.
4. Monolithic: For example, large-area full-page seamless or seamless monolithic packaging of medicines, tapes and tablecloths. Such as mineral water, drinks, labels, bottle stickers and other single packaging bags. Pay attention to the net content, the bar code should not be too close to the heat sealing edge, generally there should be a distance of 3 mm For the bottle sticker packaging with a single base material of pvc, it is mainly because the base material of pvc is a shrink film. According to its paper bag characteristics, (1) jelly jelly pocket version. The effective size of the cross-sectional drawing must be increased, which is beneficial to the sticking film when customers make bags. Moreover, due to the characteristics of the carrier and the packaging bag, shrinkage should generally be considered, that is, the whole pattern should be deformed and enlarged in the circumferential direction. (2) Beer label: The base material is printed on the surface with multi-station aluminum boxes, and the cross section should be enlarged to facilitate cutting.
5: Money packaging. The first two dimensions (equal) are greater than the last two dimensions (equal). Guangzhou Ye Jun focuses on packaging design 15.
