Today's packaging materials are diverse, whether it is outer packaging or lining, good quality, and can be used for a long time is what customers are willing to buy. The color film inner bag is a common packaging material, we need to sew well in the production process, the suture will not pass will affect its use. So how to sew the inner bag, what do you need to pay attention to? Check it out below!
As a packaging material, our first consideration is that it is strong, because it is generally loaded with very heavy things and is used repeatedly, so whether the container bag is strong is an important quality assessment. So in the material must be paid attention to, but the general PE material is very strong, only the stitching step needs to be strengthened, many just sew a line, the result is that there may be gaps, gaps will affect the service life of the container bag, so the shortcomings appear, if the quality of the line is not qualified, then the load-bearing force is not strong.
Generally, the raw material base cloth of the container bag and the sling should be improved, and the stitching of the color film inner bag should also be particularly firm, and strengthening sewing should be used. It is OK to fold and sew twice for ordinary sewing, fold and sew twice for strengthening sewing, and then add twisted edge. The bag inside the bag sometimes contains powder, such as mineral powder, powder, flour, etc., general enterprises are using machine air filling, ordinary food bags are filled by air, powder will not leak out from the pores at the seam with the air flow, in this case can not use PE.
Through the introduction of the article, we should have some understanding of the importance of the stitching of the packaging bag, if the stitching of the color film bag is not good, not only the packaging bag can not be used permanently, but also the product is likely to fall, which is not what we like to see.
