for plasticsfor plastic filmfor packaging

Overview
The Zhirui 3.0plus rotogravure printing machine for food packaging from Shaanxi Beiren combines over 60 years of manufacturing experience with advanced gravure technology. It is designed for flexible packaging substrates (OPP, BOPP, CPP, PET, PE, Nylon) and delivers heavy ink laydown, stable color and long-run durability.

Key features and benefits
The press offers ±0.1mm registration at high speed, chrome-plated engraved barrels for extended life, multi-zone drying with VOC monitoring for reduced solvent residues, Electronic Line Shaft (ELS) with independent servo motors and automatic viscosity control to maintain Delta E < 2.0 during runs.

Product description from page
The Zhirui 3.0plus processes flexible films into food-safe packaging with vivid color and wear resistance. Its ELS architecture eliminates mechanical gear errors and shortens setup time; closed-loop tension control and a seven-motor system ensure web stability throughout long production runs.
