The drawing of mesh polypropylene bags:
Polypropylene mesh bags start with a mix of raw and extra materials. An extruder melts and extrudes these into a film. Next, the film cools. It is then divided into filaments (blanks). Producers stretch and orient the filaments to make them flat. Finally, these flattened filaments are wound onto a spool to make spindles. This is the first step in making mesh polypropylene bags.
The weaving of mesh storage bags is a unique process.
The weaving machine interweaves the warp and weft of the flat yarn to make a cloth. Laminating: Laminate the upper mouth white film and the middle trademark film on the correct position of the mesh cloth. The mesh storage bags without the trademark and white film do not need this process.
The sewing of mesh polypropylene bags:
Stitch the bottom. We usually choose the flat stitch method. The curling has three folds. The side’s width should be more than 32.5px. The stitching should be parallel. The distance between the edges is 1/4. Floating thread and not returning stitches. It is in the middle of the fold. It should have no skipped stitches, floating lines, and so on. The side and bottom of the mesh fruit bags are woven together when weaving the mesh onion bags. Cut the edge with a knife and double-weave the bottom of the mesh storage bags.
The detection of mesh storage bags:
Length and width: There should not be any deviation.
Colour: There should be no significant differences between mesh polypropylene bags from the same batch
Stain: No Significant pollution of mesh bags bulk is forbidden.
Bag edge: Mesh polypropylene bags must not have significant irregularities.
Serial port bag: It should be regular, and the distance should be sufficiently aligned.
Broken weft and warp: Each mesh polypropylene bag promises to have two non-adjacent ones, but they must be connected firmly.
Perforation is needed to fill an onion sack that needs to be covered at the mouth. For example, PP mesh net bags with a mouth string do not need this process.
