PP WOVEN BAG TO BAG PRINTING MACHINE

1. Print on finished sewn sacks directly, no preprinting on roll fabric Printing and bagmaking processes are separated. Ideal for stock sack reprinting and lastminute logo addition.

2. Flexible job change & easy size adjustment Bag size adjusted by mechanical stopper, no need to change plate cylinder circumference. Perfect for frequent smallbatch orders and sampling.

3. Low capital cost, much cheaper than rollfed stacktype / CI flexo press Small footprint, no special requirements for workshop height and floor loadbearing, low entry cost for small factories.

4. Singleside & doubleside printing available Doubleside model prints both sides in one pass.

5. Simple operation & low maintenance cost Simple mechanical structure with standard spare parts. Compatible with waterbased and solventbased ink.

6. No fabric stretching trouble Prints on rigid finished piece sacks, avoids register misregistration caused by PP woven web elongation in rolltoroll machines.

7. Optional automatic bag feeding & stacking Highend version with autofeeder to save labor, finished bags stacked automatically after printing.

Need more labor, easy to learn .

Stacktype Flexo Printing Machine


Printing units are stacked vertically; each unit has independent impression cylinder. Doubleside printing (2+2, 3+1,4+0)


1. Occupies relatively little floor space.

2. Printing plate cylinders must be changed for different print repeat lengths.

3. Printing precision is higher than that of horizontal unit-type flexo presses.

Inline / Unittype Flexo Printing Machine


1. Each printing unit is independently controlled by a dedicated servo motor.

2. Printing across different repeat lengths is possible without the need to change print cylinders.


1. Very long web travel path. PP woven fabric is prone to stretching, registration heavily depends on tension performance; registration accuracy is worse than CI press.

2. Huge floor space, requires long workshop length.

3. Register precision(+/-2mm)

CI (CentralImpression) Flexo Printing Machine


All printing stations surround one largediameter central impression drum. PP woven web wraps tightly on drum surface with short web path, minimizing fabric stretching and distortion. Designed for highaccuracy, highspeed mass production


+/-0.15mm

1. Excellent register accuracy Woven web clings to central drum with short web travel to minimize material stretching. Registration accuracy reaches ±0.10.15 mm. Color alignment stays stable during longtime highspeed running, capable of fine patterns, logos and gradient effects.

2. Highspeed for largevolume orders Max printing speed: 120180 m/min. Material waste decreases with larger batch size, ideal for mass production with infrequent job changes.

3. Uniform & stable ink output All color units share one central impression reference. Even ink laydown on rough woven surface with consistent batchtobatch color. Equipped with corona treatment for strong and scuffresistant ink adhesion.

4. Wide substrate compatibility Suitable for plain PP woven fabric, laminated and coated woven material. Lowtension web handling prevents wrinkles on thin & soft woven cloth.

Gravure printing machine for BOPP, PE film printing, then laminated with PP woven fabric


English Introduction Rotogravure printing machine is the mainstream equipment for BOPP colorfilm printing. It adopts engraved metal gravure cylinders for rolltoroll continuous production. Equipped with unwinder, corona treatment, multicolor printing units, independent drying ovens, automatic register control, tension control, web video inspection and rewinder. Compatible with BOPP, PET, CPP, metallized film and other substrates. It delivers thick & rich ink layer, highsaturation color and fine dot reproduction, widely used for premium food packaging film, laminated film and largevolume longrun ordersAlibaba.co...
