Matters related to manufacture of octahedral sealed bags
1. The quantity of plate making should be paid attention to before production. When printing the octahedral seal bags, the front, back and bottom are printed at the same time, and the two sides are printed separately. Therefore, two sets of gravure plates should be made for each octagon package. Therefore, it is recommended that customers should use less colors for the side edges when designing, and generally do not exceed three colors, and design more information on the front, back and bottom. The plate making quantity of the octahedral packaging bag is to make a set of plates on the front and back separately, and make a set of plates on the two sides separately. After adding up, the total plate making quantity is obtained.
2. Tracking the side pattern of the octahedral packaging bag. Because of the limitation of the machine, the side of some materials can't track the position during bag making. Therefore, the side of some materials should be treated as pure color printing or random pattern in design.
3. Specific size of customized octahedral packaging bag
Height limit: because of the high mold cost of bag making equipment, a side size is set first, that is, the side height is 75mm. The volume of packaging can be adjusted from the change of front length and width to meet the volume change of different products.
Length limitation: due to the limitation of bag making equipment, the length of bag has the maximum value while the width is not limited. The calculation method of the limit length is: length + side height ≤ 420mm; that is, if the side height is 75mm, the length of bag cannot exceed 345mm.
Width to height ratio: similar to the elegant patent bag, the front width of the eight sided flat bottom bag must be greater than the side height, that is, the bottom of the bag cannot be square, so the front width of each package must be more than 4mm larger than the side height.
4. Other details of the octahedral package. The center line of the zipper is fixed at 30mm from the top, and the easy tear opening is fixed at 15mm from the top. The four corners of the bag can be rounded. The width of eight sealing edges is 6mm. The delivery time of the product is 30 days.
5. The octahedral packaging bag needs innovative design. We also hide the easy tear thread at the tear opening of the flat bottom bag with eight sides to improve the flatness of the bag after the package is torn, so as to improve the product grade and attract consumers.
