NP-7A Portable Bag Closer

NP-7A portable bag closer for handheld bag sewing

The NP-7A is a hand-held portable bag closing machine designed for light industrial packaging. Its single-thread chain stitch closes Kraft paper, PP/PE woven cloth, cotton, hessian, and jute bags, making it a flexible choice when operators need a mobile bag sewing machine for varied materials.

Built for dependable production use, the NP-7A combines steel cams, automatic oil-pump lubrication, and a built-in thread cutter. The fixed 8.5 mm stitch length creates a consistent chain-stitch closure while the portable format keeps the machine easy to position around filled bags.
