Abstract:
The polymeric material having oxygen barrier properties and low light transmission characteristics, in particular within the UV and visible light wavelengths and comprises (A) a polyester, (B) mineral particles, (C) a polyamide, and (D) at least one transition metal catalyst. Preferably the amount of mineral particles is not more than 26 wt % of the total weight of the material, and is not less than 20 wt % of the total weight of the material.
