Does a polylam capsule use the same machine to shrink it as a PVC one?

Thanks,

They have polylaminate outside and foil inside thus you would need a foil spinner.

Ryan,

If the shrink oven is built to shrink capsules it will certainly shrink PVC but not the other way around. As Kristian mentioned - we spin / rotate the container at higher line speeds. At lower speeds (<80 bottles per minute) we don't need to rotate with our shrink ovens. The point of rotation is to put heat on the capsule from all directions for even shrink. If the dwell time is great enough inside a properly designed oven, you don't need to spin.

PVC will shrink at a much lower temp and can shrink up to 60% of its' original size. Capsules reqire much higher temp and are designed to shrink about 15%.
