What Equipment Do You Need to Open a Paper Bag Factory?

Complete Production Line Configuration Solution

Against the backdrop of advancing global plastic restriction policies and surging demand for eco-friendly packaging, paper bags have become a mainstream choice for shopping, food, gift and industrial packaging, thanks to their biodegradability, high strength and excellent printing performance.

The key to opening a paper bag factory is to build a fully automated, high-efficiency and cost-effective production line. Equipment configuration directly determines production capacity, product quality and return on investment. Drawing on the rich industry experience of Rokin Technology, this article systematically introduces the core equipment, complete production line configuration and selection guidelines to help new factories launch operation quickly.

1. Core Equipment for Paper Bag Production Line

Paper bag production covers five major processes from raw paper roll to finished goods: raw material processing, printing, bag making, post-processing and auxiliary supporting systems. All core equipment is essential for smooth operation.

1.1 Core Bag Making Equipment

As the heart of the production line, paper bag machines are divided into three main types: square bottom paper bag machine, v bottom paper bag machine and paper bag machine with handle inline, suitable for different application scenarios.

Fully Automatic Square Bottom Paper Bag Machine (Main Model)

Application: take away bags, food bags, clothing bags and more. Features strong load-bearing capacity and stable standing performance, being the most popular bag type in the market.

Functions: Automatic paper roll feeding, gluing, tube forming, fixed-length cutting, bottom folding and sealing, counting and stacking.

Fully Automatic V Bottom Paper Bag Machine

Application: Food takeaway bags, snack bags, bakery bags and agricultural bags, with simple structure and low production cost.

Functions: Automatic paper feeding, perforation, folding, pointed-bottom bonding, breaking and collecting. It supports high-speed production with thin paper.

Technical Parameters: Running speed up to 120 m/min, suitable paper weight: 40–80g/m².

Paper Bag Machine With Handle Inline (Twisted Handle Making/ Gluing All-in-One Machine)

Application: Shopping bags, gift bags and exhibition bags with paper twisted handles or flat paper handles for easy carrying.

Functions: It can work online with square-bottom machines or run independently. Automatically completes handle making, gluing, pasting and reinforcement. The handle positioning error is controlled within ±1mm.

1.2 Printing Equipment (Optional)

If you need customized paper bags with brand logos, patterns and texts, flexographic printing machines are the ideal choice for roll paper production lines.

Configuration: 2–4 color flexographic printing machine, overprint accuracy ≤ 0.5mm.

Advantages: Integrated unwinding, printing, drying, cooling and rewinding. It can connect seamlessly with bag making machines to realize printing + bag making integrated production, reducing handling loss and labor cost.

Paper Compatibility: 30–120g/m² paper roll, maximum printing speed 120 m/min.

1.3 Raw Material Processing Equipment (Necessary)

Slitting Machine (Optional)

It cuts large original paper rolls into standard widths required by bag machines, and also cuts sheet paper accurately. Equipped with high-speed round knives, it ensures smooth cutting edge without burrs.

1.4 Post-Processing Equipment (Optional)

Automatic Finishing & Bundling Machine

Automatically counts, stacks and bundles finished paper bags, 50–100 pieces per bundle. It greatly saves manual work and facilitates storage and delivery.

1.5 Auxiliary Supporting Equipment (Essential)

• Air Compressor: Provides stable air pressure of 0.6–0.8MPa to drive cylinders, deviation correction systems and glue control valves.

• Transformer: China standard industrial voltage is 380V/50Hz. A dedicated transformer is required according to local voltage for overseas installation.

• Voltage Stabilizer: Essential for regions with unstable power supply. It protects electrical components and avoids machine failure or burnout caused by voltage fluctuation.

2. Conclusion

To set up a paper bag factory, you shall configure the production line reasonably according to your production capacity, budget and product positioning. Take Square Bottom / V Bottom Paper Bag Machine as the main host, and optionally equip printing machine, slitting machine and bundling machine. Supporting with air compressor, transformer and voltage stabilizer, you can realize full automatic production from raw paper roll to finished paper bags.
