ABSTRACT:
A heat-shrinkable opaque white film of this invention includes a core layer, and white back and front layers, the core layer having a chromatic color impervious to light at wavelengths of 380 to 500 nm or an achromatic color. The core layer may contain a black, yellow, red, or brown pigment. The heat-shrinkable opaque white film in a preferred embodiment has a transmission factor to light at wavelengths of 380 to 500 nm of 5% or less. In another preferred embodiment of the heat-shrinkable opaque white film, the core layer has an achromatic color and the film has a transmission factor to light at wavelengths of 200 to 600 nm of 3% or less. A shrink label of this invention has the heat-shrinkable opaque white film, and a preprinted ink label layer arranged on a surface of the front layer of the film. A labeled container of this invention includes a container body and the shrink label arranged on the container body. This labeled container can prevent discoloration and deterioration of contents induced by light, enables clear printing typically of a design and gives excellent visual impression of the contents.
