Heat Shrinking Packaging
Shrink package is a typical package for many kinds of food, toys and other consumer goods, the process is wrapping plastic (plastic sealed in the L-bar or any other sealer) and passing through the heating tunnel which will shrink the plastic to conform the contour of package.
CHANGWEI is offering PTFE mesh conveyor belt for transporting package through oven, and silicone coated fiberglass fabric is installed at both ends of heating tunnel, working as curtain to keep heat inside tunnel.
Our PTFE mesh belt can allow heat air pass through and make the heat transfer better inside the oven, it offer excellent release surface for shrinking package.
