FIELD: physics.
SUBSTANCE: container contains a matrix based on thermoplastics and, at least, two inorganic fillers with a lightproof function dispersed in the matrix. The matrix is formed by, at least, one polycrystalline polymer and one amorphous polymer. As a polycrystalline polymer, the matrix contains polyethylene terephthalate (PET), and as an amorphous polymer - high impact polystyrene (HIPS). The ratio of PET to HIPS is 10 to 50. Inorganic fillers contain titanium dioxide (TiO2) and aluminium (Al). The mass ratio of TiO2 to the weight of Al is from 50 to 150. The final composition of the container is obtained by mixing PET with a concentrated additive containing HIPS and inorganic lightproof fillers.
EFFECT: high lightproof level in the entire visible region of the spectrum in a lightweight container.
