RESIN COMPOSITION, PACKAGING STRUCTURE AND METHOD OF REGENERATION THEREOF

摘要

A resion composition in which a coloring component comprising a polymer and having a regular configuration as a coloring principle is contained in a matrix resin, and a temperature at which the coloring component is decolored is higher than a temperature at which the matrix resin is processed. A packaging structure in which, on at least a portion of the surface of the packaging structure, portions which are different in optical characteristics from the surface are periodically arranged by use of a fibrous structure.
