SED-TMJ-Y is a fully automatic sleeve-type heat-shrink wrapping line — sleeve sealer plus shrink tunnel — designed for tray-less collation of single bottles or packs. It runs the full chain of conveying, bottle alignment
Funcionamiento
Bottles arrive on the infeed conveyor, are aligned into the chosen pack pattern (6/9/12/15/18/20/24), then wrapped with PE film fed through a photoelectric-controlled feeder. The sleeve sealing knife — steel with a Teflon coating — performs a constant-temperature heat seal followed by a rapid cooling structure that locks the seal. The collation transfers into the shrink tunnel (1500 mm long, 700×500 mm mouth) where two centrifugal hot-air loops circulate heat across the pack inside a 3-layer insulated chamber, shrinking the PE film tightly. A reinforced cooling/setting channel hardens the wrap before the pack exits at the 850–950 mm discharge height.
