Barrier Shrink Film Lines

HB Series line for barrier low temperature shrink film includes the following process steps: extrusion and forming primary tube; reheating and reblowing for stretching in two directions, annealing, cooling, randomizing and unwinding. These lines are typically making 5-11 layers. Tronoplast offers different systems for these steps. The Tronoplast line can be operated with common barrier materials: EVOH, PA, and PVDC.


Can be configured as per client specification.
