According to one embodiment, white-coloured PVC-free lining has preferred light reflectance. PVC-free lining is resistant to deformation under load. Furthermore, said lining has low anisotropy, that is, said lining has minimal differences in physical properties in different directions. Disclosed lining also has high shrink resistance.

EFFECT: invention enables to produce a panel for inner surfaces, having environmental friendliness and functionality.
