Vertical L Bar Sealers
What’s vertical L bar sealers?
A vertical L-bar sealer is a specialized shrink wrap machine. Unlike traditional L-bar sealers, which utilize a scissor-like closing motion, the vertical L-bar operates with an up-and-down sealing mechanism. As a result of this motion style, it is now possible to shrink wrap taller products like 15cm efficiently.

Tengyi has been manufacturing automatic L-bar sealers since 2014 for a variety of industries. TY-5545Q and TY-5545CZ are two professional L bar sealers tailored to meet different industrial packaging needs.
