CHAMPION | Automatic Paper Bag Machine Manufacturer & Supplier

Machine Description

The digital paper bag printing machine is a plate-free inkjet printing system designed specifically for packaging products such as paper bags and tote bags. Using CMYK four-color inkjet technology, it can directly print electronic files (such as designs, text, and variable data) at high speed onto absorbent surfaces such as kraft paper, greaseproof paper, and biodegradable materials. Supporting single- or double-sided printing, it is suitable for small-batch customization, personalized logos, and variable data printing, significantly reducing the minimum order requirement for traditional printing.

Machine Features

Plate-Free & Small-Batch Customization
● Eliminate the traditional plate-making and plate-making processes of traditional printing; simply import the design file and start printing directly, significantly shortening production cycles.
● Single-piece printing, low cost, particularly suitable for personalized orders and urgent replenishment.
Fully Automated Production System
● Integrated dual-feed system and automatic receiving device support continuous feeding, reducing manual intervention, allowing one person to operate multiple machines.
● Automatic shutdown upon material runout, and a meter counter precisely controls print quantity for improved stability.
Efficient Printing Capacity
● Speed ??range: 2,000-20,000 pieces/hour (adjustable depending on design complexity).
Wide Material Compatibility
● Compatible with a variety of paper bag materials: kraft paper, greaseproof paper (barbecue bags), hamburger paper, biodegradable lunch boxes, etc.
● Expandable printing capabilities for other packaging: paper cups, pizza boxes, seed cards, round fans, etc.
Color and Precision Advantages
● CMYK four-color printing, unlimited color combinations, and photo-quality gradient effects. 
● Utilizes a circulating ink supply system (such as XAAR printhead technology) to reduce the risk of printhead clogging and ensure precise ink droplet placement.
Environmentally friendly and economical
● Uses water-based ink, free of volatile organic compounds (VOCs), meeting green production standards.
● Low energy consumption (select models reach 3kW), saving electricity and storage costs compared to traditional offset printing (no printing plate storage required).
Typical Applications
● Commercial customization: Branded tote bags, holiday gift bags, promotional paper bags.
● Food packaging: Food-safe printing on toast bags, barbecue bags, hamburger wrappers, and more.
● Industrial packaging: Multi-color printing on woven ton bags and industrial kraft paper bags.
