Closer Sewing Machine
Stop losing time on your bagging line. The right closer buys you 2 extra hours a day.
The GK26(NP-7A) series portable bag closer wasn't built to just "get the job done." It was built to keep your line moving-fast, clean, and without the headaches. No jams. No skipped stitches. No constant babysitting.
Two machines. Two clear missions.
If you're bagging standard loads under 60kg (132 lbs)-grain, feed, fertilizer, pellets-this is your machine. It locks the bag tight for transport, but your customers can pop it open with one pull. No torn bags. No knives. No frustration. For operations that reuse packaging, that alone pays for the machine.
Over 60kg, Export containers? High-density powders that shift and stress the seam? This one's built different. Two threads interlock for twice the holding power. Bumpy roads, stacked pallets, long hauls-your seam stays intact. End of story.
1,250 RPM. 6.5mm stitch length. Built-in automatic trimmer cuts the thread the instant each bag is done. That tiny fraction of a second per bag adds up to 1–2 extra hours of productive run time every single day. That's not a feature-that's a production boost you can take to the bank.
Built for the plant floor, not the showroom
Dust is the enemy. The GK26's semi-sealed housing keeps it out. Critical parts are machined from aircraft-grade aluminum and hardened alloy steel-wear components get extra surface treatment to last. And the built-in oil pump means no one has to remember to oil it every morning. Just turn it on and go.
Paper. Woven poly. Jute. Multi-wall. It sews them all.

Q:1.What's the real difference between GK26-1A and GK26-2A? Which one do I actually need?
A:Simple answer: it's about your bag weight and how your customer opens it.
Get the GK26-1A if you're bagging standard loads under 60kg (132 lbs)-think grain, feed, fertilizer, pellets. It sews tight for transport, but your customer can pop the seam with one pull. No knives, no torn bags, no complaints.
Get the GK26-2A if you're bagging over 60kg, shipping export containers, or handling high-density powders that stress the seam. Double threads interlock for twice the holding power. Bumpy roads, stacked pallets, long hauls-zero seam failure.

Q:2.What bags can the GK26 series sew?
A:Pretty much everything you'd find on a packaging line-paper bags, woven polypropylene (plastic) bags, jute bags, multi-wall kraft bags, and most laminated or coated bags. If you're bagging dry flowable materials (grains, powders, pellets, flakes), the GK26 handles it. Need to sew something unusual? Send us a sample photo and we'll confirm.
Q:3.What voltage do I need? How do I specify the right one when ordering?
A:We offer two voltage options for the GK26 series. Please specify your voltage when placing your order-they are NOT interchangeable.
110V / 60Hz - standard for the US, Canada, and other North American markets.
220V / 50Hz - standard for Europe, Asia, Australia, and most other regions.
Just tell us your country and local outlet voltage when you order. We'll ship the correct motor configuration and the right plug for your region. No guesswork. No adapters.
Q:4.How do I know this machine will actually last? What kind of quality control do you have?
A:Fair question-anyone can claim "durable." Here's what we actually do:
Materials: Critical components are machined from hardened alloy steel and aircraft-grade aluminum-not cheap castings. Wear parts get special surface treatment to resist abrasion.
Testing: Every single unit runs for 48 continuous hours on our test bench before it leaves the factory. If it skips, jams, or overheats, it doesn't ship. Period.
Real-world track record: Thousands of units running in feed mills, grain elevators, chemical plants, and fertilizer facilities worldwide-some for over 5 years with nothing but basic maintenance.
ISO-compliant assembly: Not a marketing sticker-actual process control throughout manufacturing.
We don't build machines to look good on a shelf. We build them to run-shift after shift, year after year.
Q:5.What's your MOQ? Can I test one unit before committing to a larger order?
A:Absolutely-and we actually recommend it.
Here's how we work:
First order (sample/trial): 1 unit minimum. We strongly encourage you to run one machine on your actual line first. See how it handles your bags, your operators, your shift schedule. No pressure.
Bulk orders: Once you're satisfied with the trial unit, our standard MOQ for production orders is 100 units.
Volume pricing: 100+ units get significant tiered discounts-the more you order, the better your per-unit cost.
We don't believe in forcing you to commit to hundreds of units upfront. One sample unit lets you validate performance on your own terms. Once you see it run, we're confident you'll come back for the 100.
Q:6.Is it easy to operate? Do my workers need special training?
A:
It's about as simple as it gets.
Here's the truth: if your worker can operate a handheld drill, they can run a GK26. The learning curve is measured in minutes-not days.
