Rebuilt Stone/Premier Tech Pinch Bag Sealer

Model 90-J Pinch Bottom Bag Closer efficiently closes the open top of filled pinch bottom open-mouth multiwall bags and woven polypropylene bags.

It activates the pre-applied hot melt adhesive, folds the top flap against the face of the bag and compresses to set the closure, providing a strong, attractive package.

Model 92-J Pinch Bottom Bag Sealer/Closer provides an effective double closure of pinch bottom open-mouth bags by sealing the bag’s inner poly liner first.
