Since 1990, Esatec France has been working for the printing & packaging industry. The company is a specialist in the design and manufacture of successful 360 degreewindow patching machine

The DigiStar WPPP is a multi functional automatic window application systems unit which cuts film in line from roll and places pre-creased / die cut plastic windows onto finished carton blanks using a highly bespoke and electronic pre programmed management system, encompassing a very tactile pick and place movement process incorporating a cold glue stencil application unit, if required two windows can be placed in line in one operation.

With unlimited design possibilities, the carton can incorporate any shape as the window is placed on the inside – meaning glue points and bleeds are discretely hidden, ideal for seamless, luxury packaging.


To monitor the accuracy and general running of the WPPP, an interactive touch screen presents statistics of the job and notifies the operator of any mechanical mal-functions. The tactile device stores details of all productions made, allowing automatic adjustment of the machine for repeat runs.


Whilst performing with utmost accuracy, the WPPP also has the ability to produce tri-fold cartons – an increasingly popular aesthetic device seen more often in up-market or luxury packaging. Cartons are fed into the machine in a normal fashion, but the machine will then pre-split the carton, insert a full window between and eventually glue it.

The result is a four panel window which effectively show cases the product – presented beautifully in 360-degree angles, unlike most other packaging designs.
