Rotogravure printing press Zhirui 3.0

for plasticsfor plastic filmfor packaging

Overview
The Zhirui 3.0plus rotogravure printing machine is engineered for high-volume food and flexible packaging production. It converts substrates such as OPP, BOPP and CPP into food-contact packaging with precise registration, high ink laydown and long-term durability. The press supports long production runs while meeting common food-safety requirements.

Key Product Highlights
Registration precision ±0.1 mm at production speeds; chrome-plated engraved cylinders for extended service life; multi-zone hot-air drying with VOC monitoring; Electronic Line Shaft (ELS) drive with independent servo motors per unit; seven-motor closed-loop tension control for stable web handling.

Applications

• Snack food packaging: high-resolution graphics for chip bags, confectionery wrappers and biscuit pouches, including metallic effects.
• Retort pouches: compatible with heat-resistant films for ready meals and sauces, maintaining print alignment through thermal processing.
• Beverage shrink sleeves: produces vibrant shrink sleeves with controlled drying to prevent premature shrinkage.
• Dairy and frozen food packaging: prints on cold-seal and low-temperature films, ensuring seal and print registration.

Operational Advantages
High registration accuracy across multiple color stations to reduce waste and rework.
Durable chrome-plated cylinders minimize plate changes and downtime for long runs.
Multi-zone drying with VOC monitoring lowers solvent residues to support FDA and EU food-contact guidelines.
Closed-loop pressure and tension control adapt to ultra-thin films (≈12 μm) and non-absorbent substrates.
Engraved-cylinder technology enables variable ink depths for photorealistic image quality and consistent color density.
Automatic viscosity control maintains ink consistency and tight color tolerances during production.
