Bag bag type with the idea of design

Generally divided into back sealing packaging form four seal bag, bag, pillow bag, single chip bags. 1, the back seal bags: design position arrangement. Trademark, name, net content, bar code and other important images can't near the hot sealing side too, so as to avoid heat sealing after the seal design, positive graphic can enter the back, but won't get into the positive pattern on the back. Typesetting, printing direction must be the same as that of heat sealing side, front, back by overall average each place centered around inside cell size. 2, pillow bag: is divided into three kinds, standard pillow type bag, inequality pillow bag and side pillow bags. Lateral sealing pillow bag is divided into no heat sealing side, unilateral heat sealing side, on both sides of the hot sealing side. Design location arrangement requirements; Trademark, name, net content, bar code and other important graphic can't get too close to heat sealing side, lest will design after heat sealing seal; Is on the back, side, designs the overall general place centered around inside each cell size; Are back pattern typically into the side. Two sides design must not enter the positive and the back, if the profile by entering will affect beautiful; Typesetting, printing direction consistent with hot sealing side. Is on the back of the pattern content or on the back of the same pattern as a whole, after the pattern on the back of a thermal seamless, inequality positive size than the back size pillow bags. Three, four sealing bag: four seal bag is divided into five kinds of bag type, standard four seal bag, 3-side, self-supporting bag, zipper bag, single cladding aluminum bag. （ 1) Standard four seal bag. When the heat sealing side is transparent, the front by slightly more than the back graphic, graphic never than positive picture and text, on the back to make the paper bag after positive graphic can hold off on the back. （ 2) 3-side. Is no heat sealing side, between the back more used for packaging bags, generally do spot on the back, typesetting, back must row together. （ 3) Self-reliance bag: typesetting with four sealing bag similar standards. Is, back to head butt or tail to tail, which must be horizontal arrangement, to facilitate in the process of cutting part in bag and pillow base, both to ensure with pillow base direction and printing in the same direction. Unit lies in the two groups, two groups of units must be transparent. （ 4) Zipper bag: typesetting with standard four seal bag similar, positive and arrange back to head butt or tail to tail, which must be horizontal arrangement, to facilitate in the process of cutting part at the top of the bag gallas chain, namely guarantee with zipper direction and printing in the same direction. Unit lies in the two groups, two groups of units must be transparent. （ 5) One-side coated aluminum tape: also called Yin and Yang bag, generally positive not coated aluminum, coated aluminum on the back. Such as back crosscutting, is back to head butt, and demanding a transparent between is back. Such as design background, the edge will be widened carving. How many units side-by-side is back, and just, general must row together back to back. 4, single chip: drugs, for example, tape, full version of the tablecloth and other large seamless or seamless single chip packaging. Such as mineral water, beverages, labels, bottle to stick the packing bag of single chip, etc. Pay attention to the net content, bar code can't be too close to the heat sealing side, generally have 3 mm distance. For monolithic substrates is PVC bottle packaging, substrates is mainly for PVC shrink film, paper bag according to its characteristics. （ 1) Sense of jelly and jelly bags. Crosscutting map size must be increased effectively, to help customers in the bag bag film and, due to the fundamental and characteristics of the packaging bags, generally consider contraction, namely design whole circumferential deformation amplification. （ 2) More than beer labels: substrates aluminum box, table printing, crosscutting map to have more, to facilitate cutting. 5: money. Two positive size ( Equal) 'the back more than two dimensions ( Equal) 。
