Technical Highlights

Machine Structure

The machine's body is constructed from 12mm thick steel plates and cast iron, welded into a single unit. It undergoes high temperature aging treatment at the factory to eliminate internal stresses, ensuring no resonance or vibration during high speed operation. The body remains distortion free for five years of use, and forming accuracy remains stable over the long term.

Modular split unit design

The feeding, forming and collection units can be dismantled for hoisting; expansion modules for in line printing, lamination and perforation can be seamlessly added at a later date, ensuring the equipment retains its value and is upgradeable.

One machine compatible with all paper types

Suitable for kraft paper, white card, laminated coloured paper, greaseproof paper, recycled paper and thin waxed paper; simply fine tune the tension, adhesive quantity and pressing pressure via the touchscreen to switch between production runs

Online Maintenance

90% of debugging and parameter related faults are resolved online, with after sales response times far exceeding those of our competitors.

Food Grade Stainless Steel

The rubber rollers, moulding plates and pressing blocks are all made from food contact grade materials; they do not leach any harmful substances and comply with environmental standards for the export of baked goods, ready meals and organic packaging.

Frequently Asked Questions

What is the difference between flat bottom and square bottom paper bag machines?

Flat bottom (Cutting by circular knife/Pointed tooth) machines produce self opening bags ideal for bread and fast food: up to 600 bags/min with 30-80g thin paper. Square bottom machines produce shopping and gift bags with flat bases for better load bearing: up to 200 bags/min with 60-150g paper

What paper types are supported?

Both of these series can process kraft paper, coated paper, laminated paper, grease resistant paper, recycled paper, and wax paper with basis weights ranging from 30 to 250 grams per square meter. A single machine can meet all your needs: no need to change the paper core.

How long does it take to change bag size?

≤2 minutes via touchscreen servo adjustment. All parameters: bag length, width, creasing depth, glue amount: are stored in recipes for one-touch recall. No tools required.

Can I add printing to my paper bag machine?

Yes. Both series support optional inline flexo printing units that print during bag making: one pass, no extra labor. The unit can be added at purchase or retrofitted later.

What is the defect rate of your paper bag machines?

Our defect rate is controlled within 0.03%: significantly lower than the industry average. This is achieved through imported servo control, precision forming, and real-time fault self-diagnostics.
