Wenzhou Lisheng Printing & Packaging Machinery Co., Ltd., with 20 years of experience in manufacturing flexographic printing machines, specializes in R&D of printing equipment dedicated to tissue paper. Adopting European technical route and high-rigidity central drum structure, the Mix series central drum flexographic printing machine for napkins is specially designed for ultra-thin napkins of 16–18gsm, solving industry pain points of traditional equipment such as low speed, register drift, long changeover & washing time, and high scrap rate.
I. Core Advantages
- High-speed & Stable Printing: Stable printing speed 150m/min, max mechanical speed 180m/min, greatly improving productivity
- Ultra-high Register Accuracy: ±0.15mm register accuracy, no drift during acceleration/deceleration, more precise multi-color printing
- Fast Job Change & Washing: Complete 6-color machine washing ≤30 minutes, closed doctor blade design for efficient color change
- Ultra-thin Paper Adaptability: Perfectly suitable for 16–18gsm single-layer napkins, resistant to wrinkling and paper breakage
- Low Scrap Rate: Short paper path + unified central drum reference, reducing paper stretching errors and production loss
II. Key Technical Parameters
- Max printing width: 420mm
- Printing length: 230–840mm (customizable with 5mm pitch)
- Applicable paper: 16–18gsm single-layer napkins
- Central drum: Diameter 1200mm, plating >200μm, radial runout ≤0.01mm
- Drying system: 3 sets of independent constant-temperature hot-air drying ovens, intelligent temperature control to prevent ink smearing
- Productivity reference: 725 sheets/min (330×400mm specification)
- Machine dimensions: 9200×2200×2700mm, net weight approx. 9 tons
- Power supply: 380V 50Hz 3P, total power 40kW
