A medicaments, container for storing a liquid medicament comprising one or more active medicaments, water and at least one preservative has a preferably cylindrical wall defining an interior space for such liquid medicament. The wall includes at least two opposed portions composed of a polymer material with a thickness of between 0.3 mm and 3 mm, a light transmission at 400 nm of 25% or more measured through the opposed container wall portions when the container is filled with water, using a standard spectrophotometer and air as reference. The polymer wall portions are of a material comprising at least 70% by weight of a linear optionally branched polyolefin material, the olefin monomer being selected from ethylene, propylene, butylene or a mixture thereof The polyolefin material has a crystallinity above 35% by weight, measured by differential scanning calorimetry, by cutting pieces from the container walls and heating them in an aluminum pan from 10 DEG C. to 270 DEG C. at the scanning rate of 10 DEG C./min, recording and integrating the melting endotherms, and using the value of 209 J/g for 100% crystalline polypropylene as a reference. |
