High-Speed One-Pass Digital Printer for Molded Pulp Food Containers

Our Digital Printing Equipment is designed as a core printing module within an automated pulp molding packaging or industrial production line. The standard production line composition includes:

• Automatic Feeding System: Wet/dry blank feeder compatible with robotic arm or conveyor input for continuous product supply
• Pre-Treatment Unit (Optional): Corona or plasma treatment station to enhance ink adhesion on pulp fiber surfaces
• Core Digital Printing Unit (This Equipment): High-precision piezo inkjet system with UV/LED or water-based ink delivery
• Integrated Curing/Drying Tunnel: UV-LED or IR drying unit for instant ink solidification and smudge-proof finishing
• Vision Inspection System (Optional): CCD camera system for print quality verification and automatic defect rejection
• Unloading & Stacking System: Automatic collection of printed products for downstream packaging
• Centralized PLC Control Panel: Touch-screen HMI with recipe management, speed synchronization, and variable data printing (barcodes, QR codes, serial numbers)

Note: The line can be customized with custom infeed/outfeed extensions, multi-angle printing stations for 2-3 surface printing, and robotic integration to match your upstream forming equipment.

Our Surface Digital Printing Equipment is a high-efficiency, eco-friendly direct-to-object printing system specifically engineered for high-quality surface decoration on molded pulp products, including food containers (clamshells, trays, bowls, cups), seedling pots, and industrial protective packaging.

Utilizing advanced single-pass piezo inkjet printhead technology and a fully customizable UV-curable or water-based ink delivery system, the machine applies vibrant, scratch-resistant graphics, logos, variable data (barcodes, QR codes, serial numbers), and text directly onto the complex, often irregular surfaces of pulp molded products.

• High-Speed Single-Pass Printing: Up to 60 meters/minute (depending on resolution) for maximum production throughput
• Exceptional Print Quality: Up to 600×600 dpi standard, configurable with customizable printhead arrays for higher resolutions on detailed graphics or fine text
• Superior Adhesion: Advanced UV-curable and water-based ink systems engineered for porous, textured fiber surfaces, with optional pre-treatment for optimized bonding
• Multi-Surface Capability: Supports printing on flat, curved, convex, and deeply recessed 3D surfaces, making it ideal for decorative branding of sustainable pulp packaging
• Zero Platemaking / Fast Setup: Eliminates plate costs and makes short runs, one-off samples, and variable data economically feasible for even the smallest batch sizes

The system is fully customizable to match unique product shapes, packaging formats, ink types, and factory floorplans.

The following table outlines specifications for standard configurations. Extensive customization is available to meet your unique product dimensions, print resolutions, and production targets.

This digital printing equipment is ideal for direct-on-surface decoration across a wide range of molded pulp products:

• Food Service Packaging: High-speed printing of logos, certifications, nutritional information, or decorative patterns on plates, bowls, clamshell containers, trays, and cups
• Fruit & Egg Trays: Branding, price look-up (PLU) codes, or origin labeling on textured agricultural transport trays
• Branded Custom Packaging: Low-cost, short-run customization for premium products, event packaging, or marketing campaigns
• Electronics Packaging & Industrial Cushioning: Printing part numbers, brand logos, handling symbols, or QR-based traceability codes on protective inserts
• Agricultural Seedling Pots: Printing planting instructions, date coding, or brand identity on biodegradable horticultural pots
• Medical & Cosmetic Packaging: High-resolution branding and lot/batch coding on pharmaceutical or cosmetic molded fiber packages

We understand that every molding plant, product line, and end-user specification varies. Therefore, our digital printing systems are highly customizable:

• Multi-Angle / Multi-Surface Printing: Customizable unit configurations enable simultaneous printing on 1, 2, or even 3 product sides in a single pass
• Printing Configuration: Customizable print modes enabling on-the-fly switching between high-speed bulk printing and high-resolution detailed graphics
• Variable Data Integration: Customizable layout logic allowing client-specific barcodes, QR codes, or sequential numbering
• Color Channels: Customizable color stations (CMYK, White, Primer, Orange, Green, or custom spot colors) to match brand specifications
• Custom Fixture Design: Fully customizable fixtures engineered to securely hold your specific product shapes during high-speed transport
• Vision Registration System: Customizable CCD position logic to compensate for natural dimensional variance in molded pulp substrates
• Pre-Treatment Module: Customizable addition of corona/plasma pre-treatment for fiber material requiring enhanced surface wettability
• Inline Drying Profile: Customizable zoned heat/curing parameters to accommodate fast-curing UV inks or slower water-based drying compounds
• Automation Level: Customizable integration with existing forming line output via robotic or conveyor transfer points
• Ink Type Selection: Customizable ink formulations (low-VOC water-based, UV-curable, food-contact-safe) depending on your regulatory environment

• One-Pass High-Speed Printing: Up to 60 m/min (depending on resolution) provides scalable throughput, from small-batch prototyping to full-scale production lines
• Direct-to-Object Digital Technology: Plate-less, fast setup, zero chemical waste, and near-limitless graphic flexibility
• Superior Adhesion on Irregular Fiber Surfaces: Engineered for natural textured, porous, and variable-dimensional pulp surfaces; optional pre-treatment for enhanced bonding
• Instant UV / IR Curing: UV-LED modules cure ink immediately, eliminating smudges and enabling immediate downstream handling
• Multi-Surface Printing Capability: From deep-recessed bowls to wide, flat trays, the printer handles 3D geometries, including single-side, dual-side, and edge printing
• Food-Safe Material Compatibility: Use of low-migration inks and non-toxic coatings ensures compliance with food contact safety standards
• Vision-Based Print Alignment (Optional): Intelligent camera systems compensate for product placement variation, ensuring consistent logo placement
• Intelligent Variable Data Printing (VDP): Seamlessly prints unique codes, QR identifiers, or custom info for each unit on the line
• PLC Touchscreen Control: Intuitive HMI with recipe storage for rapid changeover between product types and print jobs
• Energy-Efficient & Green Technology: UV-LED curing consumes up to 70% less energy than conventional UV mercury lamps, with low-VOC, food-contact-compliant ink options
