Quick answer: The NP-7A portable bag closer is a handheld bag sewer for light industrial and agricultural packaging. It sews a single-thread chain stitch across kraft paper, woven PP/PE, cotton, hessian and jute bags, weighs 6 kg (about 13 lb) with the thread cone, cuts its own thread, and oils itself. It's also available in 12V DC and 24V DC versions for closing bags away from AC power, and it's the most affordable bag closer we carry.
If you close bags of feed, seed, fertilizer or grain by hand, or you're tired of tying and taping bag tops, the NP-7A is the simplest way to start sewing them shut. Here's what it does, who it's for and what to know before you buy.

What the NP-7A is built for
The NP-7A is made for closing filled bags and sacks in light industrial and agricultural work. Its brochure lists agricultural products, animal feeds, fertilizer, flour and chemicals as typical applications. Because it's handheld, the operator carries it to the bag instead of moving bags to a machine. That makes it a good fit for:
- Farms, feed mills and feed stores closing bags as they're filled
- Seed and grain bagging
- Small warehouses and co-ops with modest daily volume
- Field and truck-side bagging with the 12V or 24V DC version
Why buyers choose the NP-7A
- Lowest cost of entry. It's the most affordable closer in our bag sewer lineup.
- Runs on DC power. Most handheld closers need an outlet. The NP-7A's 12V and 24V DC versions don't.
- Automatic thread cutting. The built-in cutter trims the chain at the end of each bag.
- Automatic oiling. An oil pump lubrication system keeps moving parts oiled, and the brochure calls out minimum maintenance.
- Steel cams. The brochure highlights a steel long-cam, with no plastic cams.
- Handles many bag materials. Kraft paper, woven poly, cotton, hessian and jute.
Options and attachments
The NP-7A brochure lists these optional attachments:
- Binding (crepe) tape attachment. On the product page, a crepe-tape binding and cutter assembly is listed as a special-order configuration.
- Balancer spring with hanger, to hold the machine up between bags
- Presser foot lifter
- Shoulder belt
- Thread cone cover
When to choose a different closer
- You want a closer that also sews plastic or composite bags: look at the Model F, which lists plastic, woven polypropylene, multi-wall paper, composite and jute.
- You close bags on a conveyor all day: step up to a pedestal sewing head like the Model 100 or Empress Model 101.
- Your product is a fine powder that sifts through stitching: consider pinch bottom paper bags on the PBC 6000.
