Recommendation for strong clear film-grade material 1

[walkingcube]

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!

PA12 will take some beating.

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.

Regards
Pat
