Bag sewing and closing machines
Bag closing machine: which one suits you
A bag closer and a bag sewing machine are the same machine. What changes from one to another is how it is built: that determines how many bags a day it can handle and how many years it lasts. We help you choose the right one, from the economy portable to the industrial system.
Three types of bag closing machine
The type depends on how many bags you close per day and on the bag material.
- Portable bag closerHand-held or hung from a balancer. For warehouses, farms, collection centers and low to medium output.See portable bag closer
- Industrial sewing systemA head on a pedestal over a conveyor: it sews the bag on its own as it moves along. For continuous production.See industrial sewing system
- Bag sealerFor plastic or paper bags that are sealed with heat, hot air or glue instead of being sewn.See bag sealer
Economy or industrial bag closer
Almost all portable bag closers make the same stitch and their motors run at a similar speed. That is why two machines that look the same can last very differently: the difference is on the inside.
| Economy bag closer | Industrial bag closer (Fischbein, Newlong, Megatex) | |
|---|---|---|
| Recommended output | Up to about 100 bags per day | More than 200 bags per day, full shifts |
| Ideal use | Occasional: farms, warehouses, collection centers | Daily, in a plant or production line |
| Moving parts | They wear faster under heavy use | Heat-treated loopers, feed dogs and shafts |
| Internal parts | More plastic components | Mostly metal parts |
| Lubrication | Basic | Continuous, built for daily work |
| Parts | Needles, loopers and knives in stock at Seproma | Original factory spare parts in stock |
| With heavy daily use | Needs spare parts often | Designed for years of work |
Why a quality machine works out cheaper
The purchase price is only part of the cost. If the bag closer works every day, what costs the most is what happens when it breaks down.
- A stopped machine halts filling, shipping and your staff
- Skipped stitches and poorly closed bags mean spilled or returned product
- Parts replaced every few weeks add up to more than the price difference
- A machine replaced every year ends up being paid for two or three times
The rule of thumb
Up to about 100 bags per day, or if you only sew occasionally, an economy model does the job. Above 200 bags per day, or if the bag closer is the only one on your line, invest in a Megatex (Yaohan) or an industrial model.

Frequently asked questions
How much does a bag closing machine cost?+
At Seproma, economy portable bag closers start at ₡85,000 + VAT. Industrial portables (Fischbein, Newlong, Megatex) and pedestal sewing systems are quoted according to model, voltage and accessories.
Bag closer or bag sewing machine: what is the difference?+
None: they are different names for the same machine. They are also called sack sewing machines or bag closers.
Why does one bag closer last longer than another if they sew the same?+
Because the stitch and the speed are similar, but the construction is not: heat treatment of the moving parts, whether the internal parts are metal or plastic, and the lubrication determine how many bags a day it can handle and how many years it lasts.
What thread does a bag closer use?+
Special bag closing thread, 100% polyester and lubricated. The wrong thread is the leading cause of skipped stitches and machine wear. We keep it in stock.
