Single-layer plastic container with inorganic light-shielding fillers provides a strong light shield, including near-total shields blocking the whole light spectrum, in a light weight container. The plastic container contains at least two different thermoplastic polymers that functionally complement each other. Light-shielding inorganic fillers contain at least two different inorganic substances that complement each other in their light-shielding function. The plastic compositions achieve light shielding in very light single-layer containers without the cost and complexity of multi-layer structures. Only conventional equipment and production processes are required.
