The processing of non-woven bags is relatively simple. There will be differences in workmanship, printing, and materials, and prices will also vary, but one cannot be simply said to be better. The key is to see the customer’s requirements for quality and whether the supplier is right. Responsible for quality. Production inspection standards for film-coated non-woven bags:
1. When laminating the film, pay attention to whether there is blistering and weak composite.
2. Cutting: Each set of plates has a white line, and the error should not exceed 1-5 mm during cutting.
3. The small wrinkle area of u200bu200beach piece cannot go over 2 places.
4. There are 2 white squares at both ends of each set of plates when making plates, which are where the straps are installed. Carrying straps: When ironing the lifting straps and sewing the lifting straps, they must be placed correctly, with an error of 1-2 mm. When making ordinary non-woven bags, there is no white box, but a standard must be found. The lifting straps must be consistent. The length of the strap is 45 cm, and the cloth is not less than 65 grams.
5. Running head: the error of 3 cm hemming shall not exceed 1-2 mm, the upper line is 2 mm from the hemming, no jumpers are allowed, and the stitches must be stitched once at the beginning of the sewing and the upper belt. 2.5 stitches from 1 cm.
6. Packing: When hemming, the stitch distance on the rim is 1 cm and 3 stitches, the thread spacing on the rim is 1-2 mm, and the weight of the rim cloth is 65-70 grams. There should be no wrinkles.

Whether the upper and lower can be aligned, the error does not exceed 5 mm.
Summary: From the beginning to the end, every link in the production of laminated non-woven bags is very important. The next process is the inspector of the previous process.
