Co-extrusion hot melt coating setting for running low and high melt index resins
Example 3-layer coex log on board: a high-MI layer next to a lower-MI LDPE. Starting points, not a spec. Call 800-249-0337.
The original sheet is one run on a three-layer line coating board at 300 fpm. Extruder B is off. Layer plug CCAAA. Use it as a record of what to log when a high melt-index layer runs next to a lower-MI polyethylene — not a set-up for every resin or die.
