Bottle made by vertical thermoforming technology
using pre-printed plastic sheet reels
Very successful in the drinking yogurt market with its vertical thermoforming machines that allow bottle production from PS or PP reels, Serac has recently gone a step further by adapting its simple, efficient and reliable solution to the thermoforming of bottles out of pre-printed PP reels.
The technical challenges of this new development were to define precisely the features required for the PP sheet as well as for the printing inks and to provide perfect positioning of the printed reel together with precise advance rate control.
For this particular application, Serac has equipped its machines with sensors and sets of cameras that ensure fast initial machine setting with minimum waste, and systematically check that the PP sheet is at the right place for the next stroke during production.
With this new development Serac probably offers the smallest footprint ever for on-site bottle manufacturing, using a vertical thermoforming process and requiring no labeler or sleeve applicator.
