Recommendation for strong clear film-grade material
Recommendation for strong clear film-grade material
(OP)
Hello,
I'm currently looking into a material that can be blown into strong, (almost optically) clear films.
We're currently doing some stretch blow moulding for a client on transparent bag-like food containers with very thin walls (.0025" in thickness) and have been experimenting with some film-grade PA12 (ex: Grilamid L25) with some success. However, we're looking something that with a higher tensile strength.
Does anyone have any suggestion as to what I should look into?
Thanks!

PA11 might be a little better.
Polysulphone might be worth a look.
Most data I have is for injection moulding and material rankings do change due to differing effects from being stretched in the film blowing process.
