Easy-tear opening of plastic food packaging bags seems to be a very routine process today. Except for the bag type with a relatively large load and the nozzle bag with a mouth, the easy-tear opening will be made. So what is the doorway in the seemingly simple easy to tear mouth? The following is an introduction by the manufacturer of plastic food packaging bags. There are three common easy-tear positions for food bags and food packaging bags. 1. The easy-tear opening is on the lower part of the side. Loss. The second is to ensure that products with large gram weights are not torn apart by mistake during transportation. However, since the development of the quality of the composite packaging bag, the above situation has rarely occurred, and various sales manufacturers have also taken corresponding defensive measures. The disadvantages are also obvious: the user needs to flip the bag when using it, and the printed content is all upside down, which is not conducive to the user’s reading, and is a bit anti-human. Commonly used: disposable packaging bags, three-side sealing bag type (lower side opening – three-side sealing bag type) 2. The easy tear opening is punched on the upper side, which is convenient for users to find the easy tear opening position at the first time. The printed content is displayed normally, which is conducive to reading and has a strong copywriting promotion effect. Commonly used in: self-supporting packaging bags, eight-side sealing packaging bags (opening on the upper side – self-supporting packaging bag type) 3. The easy-tear opening is on the top, which is a special position, commonly used in four-side sealing, organ bag type, back sealing bag type (The first two are mainly introduced here), the advantages are: it is convenient for users to find the position of the easy tear opening at the first time, and when the product is not used up, it is good to use the folded edge as the bottom support. The disadvantage is: because we are used to using the easy tear opening on the side, when using an accordion bag or a four-side sealing bag, it needs to be torn horizontally, and it is easy to spill the product. The printed content does not stay intact after tearing the product. Why not hit the side? It is said that the speciality of the organ bag type and the four-side sealing bag type is here, because these two types of bags have no bottom, they are rectangular, and the space capacity is relatively large. And the side of the organ bag is not sealed and cannot be easily torn. Therefore, choosing the top opening can just make use of the advantages of the bag type (folding edges) to supplement the disadvantages, and also allow users to easily unpack the bag. (Top opening – organ bag type) ps: The back sealing bag type is made of a complete film because there is no edge sealing on the side, so choose to open an easy tear opening at the top. (Top opening-back sealing bag type) The position of the easy tear opening is determined based on the design layout, so the LOGO and label information will be reserved when designing the layout to ensure that users can easily unpack products and merchants. LOGO, the integrity of most of the information. While having a good user experience, it can also achieve promotion and marketing, so that users can easily remember our brand.
