Blister Forming Roller

PVC base film web is drawn off from a reel and fed into the blister forming unit where blisters are continuously formed. The web is then led to the sealing unit over a guide track. Over the guide track, the product is filled into the blisters by suitable automatic filling unit before the web enters the sealing unit Aluminum foil is drawn off from a separate reel and is fed to the sealing unit where it is sealed with the base web, thus enclosing the product hermetically. The filled and sealed web is then fed by an indexing mechanism into the pack punch unit where the packs are separated from the web. The web trim is sheared off to allow collection. The blister pack may either be collected in bins or may be conveyed over a belt for further handling. The machine could be linked to a cartoner.
