Dear researcher,
We produce polyethylene-based shrink film (HDPE / LDPE / LLDPE), for the packaging of water bottles, the problem is that we have a big Bullseye and I would like to know what parameters in (blown film extrusion) or recipe we can change to strengthen and have a small Bullseye.I'd also like to know if we should look for a positive or negative TD shrink.
Thank you
Dear F. Madidi, are these polyolefins extrusion-blown films grades? My explanation is that may be either the MW is low and/or having a broad MWD. As you know shrink-wrap is a relaxation of highly oriented chains, so MW and MWD are the premordial parameters. My Regards
No thanks. Please go through the following documents. My Regards
