4-Color CI Flexographic Printing Machine
Sinowin’s 4-Color CI (Central Impression) Flexographic Printing Machine is a premium, high-speed industrial press engineered for flexible packaging materials that are highly sensitive to tension and stretching. Featuring a heavy-duty central impression drum configuration, the substrate is locked firmly against the single large cylinder throughout the entire printing process. This completely eliminates material elongation, delivering flawless multi-color registration accuracy, high speeds, and vibrant graphics. It is the premier investment for packaging factories mass-producing thin plastic films, sophisticated shopping bags, and food-grade wraps.
Characteristics
* Central Impression Drum Stability
Utilizes a massive, high-precision central impression cylinder where all 4 color stations are arranged symmetrically around it, ensuring the film remains perfectly stable without any shifting or stretching from color to color.
* Flawless Registration for Extensible Films
The absolute best technological solution for printing on thin or highly elastic substrates (such as breathable films, LDPE, HDPE, and stretch wraps) where traditional stack-type presses struggle with registration.
* High-Precision Ceramic Anilox & Doctor Blade
Equipped with laser-engraved ceramic anilox rollers and a heavy-duty chambered doctor blade system to execute precise, uniform micro-inking, producing razor-sharp halftone dots and crisp fine lines.
* Intelligent PLC & Automatic Tension Control
Driven by high-end servo/inverter motors and managed via a centralized digital touchscreen PLC, integrating fully closed-loop tension systems to guarantee smooth, non-stop operation at top mechanical speeds.
Use
* High-Precision Supermarket T-Shirt Bags
The industrial choice for printing top-quality, multi-color corporate logos and artwork onto thin blown film rolls before they are converted into high-end retail vest bags and grocery carriers.
* Food-Grade Flexible Packaging & Wraps
Perfect for high-speed printing on food-grade packaging materials, fresh-keeping wraps, and lamination base films for snack pouches and sanitary products.
* Hygiene & Medical Disposable Film Products
Ideal for mass-producing printed backsheets for baby diapers, sanitary napkins, disposable medical sheets, and breathable protective films.
* Premium Retail Pouches & Courier Mailers
Widely used to add sharp branding, clear tracking barcodes, and vibrant multi-color designs onto clothing boutique bags, e-commerce poly mailers, and express sacks.
