Single dustproof seam

Sewing FIBC with one dustproof cord is used for packing crystal sugar and granules.

It is used for milk powder, calcium carbonate, dust, chalk, starch …. and in cases where the bag is filled under high pressure.

The third dustproof tape can be placed on all seams or alternatively added only on critical seam eg. Bottom and outlet seam in order to save costs.
