Delivered solution

Versatile 360 B Conti machine with metal cover for standard wire chute

To partly eliminate air from the bag, the springs under the cross jaws were used

For better product alignment in Doypack bags, pneumatic vibrator was installed over the cross jaws – it shakes the foil over the product after pouring, preventing it from getting into the cross seal

Machine equipped with in-line zip cut-out, 14 mm in-line zip guides and zip unwinding

Changeover from Doypack to pillow bag takes approx. 1 hour

morf - advantages over horizontal machines

ADVANTAGES OVER HORIZONTAL MACHINES:

Universality/versatility of vertical machines (multiple bag types on one packaging machine)

Space-efficient in the production hall

Short format changeover time

Minimal foil waste during format setup

LEADING PRICE/PERFORMANCE RATIO

The quality of Doypack bags produced on vertical machines is comparable to bags on horizontal machines. The result is good-looking doypack bags with no reduction in quality

VELTEKO machines are cost-effective, featuring a compact design that maximizes flexibility in limited space and delivers high-performance packaging at a significant speed per square meter

 

GET A PERFECT BAGS FROM LDPE/LDPE FOIL

The outer laminate layer must be weldable to get a well-standing Doypack bag. In this project the foil producer added special glue or paint to achieve the result

Motorised foil unwinding (VT+) helps to control the foil unwinding (mono foil tends to stretch)
