During past over years, we met many customers who need woven sack for powder products like flours, tile adhesive powders etc, those product are tiny, easily running out from the pinhole, which makes the working environment mess and waste of product materials. Therefore, in order to improve the problem, we came up several methods:
- Using the smallest pin on the stitching machine to make the pinhole as small as possible, and shorten the distance of stitches from 1cm to 0.6cm. This method is the most favorable cost to improve the quality, which is good choice for customers.
- Using the adhesive tape while stitching, the woven sack bottom will be fully closed, this method is widely used in packaging bags like bopp laminated woven sack, kraft-paper laminated woven sack.
