Opaque single-layer bottle with light protection and production method thereof

Single-layer plastic container with inorganic light-shielding fillers, that afford a very high light shield, even a virtually total shield in the whole light spectrum, with a very light weight container. The plastic structure of the container contains at least two thermoplastic polymers of a different nature that complement each other in their function of structurally constituting the container, and the light-shielding inorganic fillers contain at least two inorganic substances of a different nature that complement each other in their light-shielding function. Due to the particular constitution of the plastic structure and the efficient combination of inorganic shielding fillers, it is possible to achieve modular light shields, even virtually total shields, in very light single-layer containers without having to resort to the complex and costly multi-layer structures that are usual when shielding levels close to absolute are sought, and all of this using conventional equipment and production processes.
