Today's packaging materials come in a variety of types, whether it's outer packaging or lining, customers are happy to purchase them for their quality and durability. The color film inner bag is a common type of packaging material. During the manufacturing process, careful stitching is essential; inadequate stitching can affect its usability. So, how should inner bags be stitched, and what should be noted? Keep reading with us to find out!
As packaging materials, our primary consideration is durability, as they typically contain heavy items and are reused frequently. The strength of the woven bags is a crucial quality assessment factor. Therefore, attention must be paid to the material, but generally, PE materials are quite sturdy. The only aspect that requires enhancement is the stitching process; many are only stitched once. This results in potential gaps, which can affect the lifespan of the woven bags. This drawback becomes more pronounced if the thread quality is also subpar, as it weakens the load-bearing capacity.
The raw material base fabric and straps of container bags must be upgraded, and the缝合 points of the colored film inner bags must be particularly strong, requiring reinforced stitching. Standard stitching is sufficient with just two folds, but reinforced stitching involves folding and sewing twice, followed by an extra overlock. Inner bags of ton bags may sometimes contain powders, such as mineral powder, pharmaceutical powder, and flour, etc. Most companies use machine air-assisted filling. Once a food ton bag is filled using air-assisted filling, the powder may leak out through the pores at the stitching lines. In such cases, PE should not be used.
Through the article's introduction, you should now understand the importance of stitching for inner bags. If the stitching of the colored film inner bags is not up to par, not only will the packaging bag not be durable, but the product may also fall out, which is certainly not something we want to see.
