- thermoplastic resin foam having a large number of fine bubbles or pores is brought into contact with an inert gas under pressure to a molten or solid thermoplastic resin, and then depressurized. It can be obtained by heating to a temperature equal to or higher than the softening temperature of the resin under normal pressure. Since the obtained thermoplastic resin foam film or sheet has a fine average cell diameter of 50 m or less, it has high reflectivity and can have a thickness of 200 m or more. It has excellent shape retention, and can be processed into a three-dimensional shape with a thermoplastic resin foam film or sheet alone. The light reflectance of a thermoplastic resin foam film or sheet generally tends to show a higher value as the number of bubbles per unit volume increases.
- thermoplastic resin foam having a larger number of finer bubbles or pores.
- the thermoplastic resin film containing the latter filler is formed by forming an unstretched film containing a filler such as calcium carbonate oxalate and stretching the unstretched film. It can be obtained by forming a large number of voids as nuclei.
- the thickness of the obtained film becomes as thin as less than 200 m, and the film alone does not have a shape retaining property, and more light leaks to the back of the film. Therefore, a plate having sufficient strength and light shielding property is disposed on the back side of the film.
