Pinch Bag & Fold Over Glue Closer
HS Automation supplies and services the Fischbein PBC 6000 pinch bag closer and the Fischbein DRC 300 double roll closer — the two machines that close pre-glued pinch bags and flush-cut multiwall paper bags without a stitch. Both seal at up to 75 linear feet per minute, both use a patented breakaway design that clears a bag jam in seconds instead of shutting the line down, and the PBC 6000 is available in a full stainless steel washdown version for wet and sanitary environments. HS Automation is Canada’s largest authorized distributor of Fischbein (an nVenia brand), and we stock parts, install, and service every closer we sell.
Fischbein PBC 6000 at a Glance
A quick look at the Fischbein PBC 6000 pinch bag closer — its patented breakaway design for easier cleaning and service, and the range of products it handles, from bakery mixes and flour to fertilizers, pet food, and powdered dairy.
What Is a Pinch Bag Closer? What Is a Fold-Over Glue Closer?
A pinch bag closer seals multiwall paper pinch-style bags that are supplied with adhesive already applied to the bag top. The machine runs the filled bag past a hot-air manifold that activates that pre-applied glue, folds the bag top over, and presses it closed. The result is a flat, glued, sift-resistant closure with no needle holes for powder to escape through.
A fold-over glue closer — also called a double roll closer — works on flush-cut open mouth paper bags that arrive with no glue on them. The machine trims the bag top square, makes a first fold, applies hot melt adhesive, then makes a second to close the bag. That double roll is what gives the bag its strength and its clean retail appearance.
Both are the right answer when a sewn closure is not — when product sifts through stitch holes, when the closure has to look finished on a store shelf, or when thread and needle consumables are a nuisance you would rather not manage. If a sewn closure is what you actually need, see the Fischbein Model F or our heavy duty sewing systems.
Common Applications
Both closers are at home wherever paper bags are filled with product that must not sift out of a stitch hole:
- Food and bakery — flour, bakery mixes, sugar, powdered dairy products, snack foods
- Pet food and cat litter — dry pet food and litter in multiwall paper
- Chemicals — powders, granulated chemicals, pesticides
- Minerals — fine powders and granular minerals
If you are running fine powders, a glued closure is usually the right call over a sewn one. Sewing is faster to set up and cheaper to buy; gluing keeps the product in the bag.
Fischbein PBC 6000 Pinch Bag Closer
The PBC 6000 is a heavy duty sealer built for automated lines. A variable speed, direct drive system pushes production up to 75 linear feet per minute, and the control panel keeps it simple for the operator: a digital temperature display, a keypad for variable speed, and an emergency stop button.
The patented breakaway design is the feature that pays for itself. When a bag jams, the swing channel opens up so the operator can clear the bag by hand — no tools, no teardown. That same access makes routine cleaning and service faster. On a line running powders and food products, it is the difference between being back up in a couple of minutes and being down for the rest of the shift.
Because the closure is glued rather than sewn, the PBC 6000 produces a sift-resistant seal that suits fine powders, granulated chemicals, pesticides, fertilizer, pet food and food products.
Fischbein DRC 300 Double Roll Closer (Fold-Over Glue Closer)
The DRC 300 seals multiwall, flush-cut paper bags weighing up to 50 pounds at production rates up to 75 linear feet per minute. In one pass it trims the top of the bag, makes a single precise fold, applies hot melt adhesive, and makes a final second fold.
Fischbein’s spiral glide folder technology is what makes that fold repeatable bag after bag — closures that are consistent, reliable and attractive enough for a retail shelf. Like the PBC 6000, the DRC 300 uses the patented breakaway design, so a bag jam means opening the swing channel for easy access.
If your bags arrive flush-cut with no glue on them, the DRC 300 is your machine. If they arrive pre-glued as pinch bags, you want the PBC 6000.
PBC 6000 in Full Stainless Steel Washdown
The PBC 6000 is available in a full stainless steel, NEMA 4X wash-down version for plants that hose down the line. If you are packing food, powdered dairy, bakery mixes or feed additives — anywhere sanitation protocol calls for the equipment to be washed rather than wiped — this is the configuration to specify. The stainless washdown build keeps the same speed, the same breakaway design and the same controls; what changes is that the machine is built to survive the wash.
For less demanding corrosive environments there is a middle option: CR Plus, a two-part corrosion resistant powder coat finish. Fertilizer and chemical plants that do not wash down but do fight corrosion usually land here.

Frequently Asked Questions
What is a pinch bag closer?
A pinch bag closer seals multiwall paper pinch-style bags that come from the bag supplier with adhesive already applied. The machine uses hot air to activate that glue, folds the bag top over and presses it closed, producing a flat, sift-resistant seal with no stitch holes. The Fischbein PBC 6000 seals at up to 75 linear feet per minute.
What is a fold-over glue closer?
A fold-over glue closer, also called a double roll closer, seals flush-cut multiwall paper bags that have no glue on them. The Fischbein DRC 300 trims the bag top, makes a first fold, applies hot melt adhesive, then makes a second fold to close the bag top.
Is the Fischbein PBC 6000 available in a stainless steel washdown version?
Yes. The PBC 6000 is available in a full stainless steel, NEMA 4X wash-down version for food, dairy and sanitary environments where the equipment is hosed down. A CR Plus two-part corrosion resistant powder coat finish is also available for corrosive but non-washdown environments.
How fast do the PBC 6000 and DRC 300 run?
Both machines seal at up to 75 linear feet per minute. The PBC 6000 uses a variable speed direct drive system; the DRC 300 has variable speed control from the same style of keypad.
What size bags does the Fischbein DRC 300 close?
The DRC 300 closes open mouth flat or gusseted multiwall paper bags weighing up to 50 lb, with a minimum bag face width of 5 in (12.7 cm) and a minimum free bag top of 6 in (15.2 cm) for a standard fold, or 7.5 in (19 cm) for the wide fold Model 300 Plus.
What utilities do these bag closers need?
The PBC 6000 runs on 230/380/460V 3-phase 60 Hz with 24 VAC controls and needs 7 cfm at 90 PSI of compressed air. The DRC 300 runs on 230V 3-phase 50/60 Hz with 24 VAC controls and needs 8 cfm at 80–100 PSI. Both are available in 575 VAC for Canadian plants.
What happens when a bag jams?
Both machines use Fischbein’s patented breakaway design. The hot-air manifold and bag folder break away instead of forcing a teardown, so a jam is cleared in minutes and routine cleaning and service are far quicker.
Should I use a glued closure or a sewn closure?
Use a glued or fold-over closure for fine powders that sift through stitch holes, for retail bags that need a finished appearance, and where bags are supplied pre-glued or flush cut. Use a sewn closure for woven polypropylene, burlap and jute, for constantly changing bag sizes, and where capital cost matters most.
