Problems solved by technology

However, plastic films are highly transparent, and if they are not printed on the entire surface, it is difficult to see characters or patterns, and because the texture is uniform, it is difficult to obtain a sense of luxury or design
Therefore, there is a problem that plastic films are difficult to attract consumers' attent

Example Embodiment

[0288] [Example 1]

[0289] The pellets of resin A1, resin A2, and resin B1 were each dry-blended in the ratio shown in Table 1 using a mixer, and the resin composition for base material layers was prepared. In addition, the particles of resin A'2 and resin D1 were dry-blended in the ratio shown in Table 1 using a mixer to prepare a resin composition for a surface layer.

[0290] The dry-blended resin composition for the base layer for forming the base layer is charged from the hopper into the single-screw screw extruder a, and the dry-blended resin composition for the surface layer for forming the surface layer is charged from the hopper In a single-screw screw extruder b, it was melted at 240°C, and these melts were laminated in a two-layer multi-manifold mold into two layers of surface layer (layer b)-substrate layer (layer a) The structure is extruded in the form of a two-layer laminated resin layer. The mass ratio of the amount of extruded resin of the single screw screw ext...

[0292] [Example 2]

[0293] Regarding the surface layer, the same operation as in Example 1 was performed except that 80% by mass of resin A'2 and 20% by mass of resin D1 were used instead of the proportions of the resin components constituting the surface layer described in Example 1. The stretched film of Example 2.

Example Embodiment

[0294] [Example 3]

[0295] Regarding the surface layer, the same operation as in Example 1 was performed, except that 70% by mass of resin A'2 and 30% by mass of resin D1 were used instead of the ratio of the resin components constituting the surface layer described in Example 1. The stretched film of Example 3.

Abstract

The present invention provides: a translucent stretched film having a matte appearance; and a translucent stretched film which preferably has excellent printability and heat sealability, while having,if desired, pencil writability. More specifically, the present invention relates to a translucent stretched film which comprises at least a base layer and a surface layer, and wherein: the base layercomprises one or more layers that contain, as resin components, at least a crystalline thermoplastic resin A having a melting point of 120-175 DEG C and an amorphous thermoplastic resin B; the surface layer contains, as a resin component, at least a crystalline thermoplastic resin D having a melt mass flow rate of 0.02-2 g/10 min at 190 DEG C under a load of 2.16 kg; and the total light transmittance is 35-85%.

Description

technical field [0001] This patent application is to Japanese Patent Application No. 2016-109469 (application date: May 31, 2016), Japanese Patent Application No. 2016-109520 (application date: May 31, 2016), Japanese Patent Application No. 2017-083157 ( Filing date: April 19, 2017) and Japanese Patent Application No. 2017-083158 (filing date: April 19, 2017) claiming priority, hereby referring to the above-mentioned descriptions, all of the above-mentioned patent applications are incorporated into this specification . [0002] The present invention relates to a translucent stretched film comprising at least a base layer and a surface layer. Background technique [0003] Conventionally, translucent paper such as tracing paper, transparent cellophane, paraffin paper, and sulfuric acid paper has excellent visibility of characters or patterns printed on the surface, and the content can be confirmed, so it has been used for medical packaging paper, Food wrapping paper, cooking...
