To provide a resin formed product with a label, for which information can be provided on the label without using ink and the information can be visually recognized from the external appearance even in a condition where the label is adhered. A resin formed productto which a labelis adhered, the labelbeing formed by laminating a layer containing a porous base layer A and an adhesive layer B adhered to a surface of the resin formed product. On the label, a rough parthaving a relatively rough surface roughness and a smooth parthaving a predetermined pattern having a relatively smooth surface roughness are formed, and a cross-sectional porosity of the label of the smooth partis from 0 to 93% relative to the cross-sectional porosity of the label of the rough part

Resin formed product with label, production method of resin formed product with label, and label

Disclosed is a stretched resin film comprising a layer (A) stretched in at least one axial direction and comprising 0 to 98 wt % of a polyolefinic resin, 2 wt % or more and less than 100 wt % of an amorphous resin and more than 0 wt % and 70 wt % or less of an inorganic finepowder and/or an organic filler. The stretched resin film of the present invention is resistant to becoming waved when offset-printed with widely-used, quick-drying offset printing inks, and thus has excellent printing properties.

Stretched resin film

The present invention discloses a multi-layered stretched resin film which comprises a base layer (A) containing 40 to 90 wt % of a polyolefinic resin and 10 to 60 wt % of an inorganic fine powder or an organic filler; and an amorphous resin-containing layer (B) provided on at least one side of such base layer (A), and containing 0 to 85 wt % of a polyolefinic resin and 15 to 100 wt % of an amorphous resin; where the amorphous resin-containing layer (B) has a porosity of 5% or below. Such multi-layered stretched resin film is successfully exempt from being waved or curled due to vehicle contained in offset printing ink during offset printing, and can thus ensure excellent printability.

Multi-layered stretched resin film

A multi-layered stretched resin film comprises a base layer (A) comprising more than 90 wt % of a polyolefinic resin and less than 10 wt % of an inorganic fine powder and/or an organic filler; and an amorphous resin-containing layer (B), comprising 0 to 85 wt % of a second polyolefinic resin, which may be the same or different than the first polyolefinic resin, and 15 to 100 wt % of an amorphous resin. The amorphous resin-containing layer (B) is disposed on at least one side of the base layer (A), and has a porosity of 5% or less. Such multi-layered stretched resin films are resistant to waving or curling caused by exposure to the vehicle component of offset printing inks during offset printing, and therefore have excellent printing properties.

A synthetic paper with a multi-layer structure comprising a biaxially stretched film of an olefinic polymer having a melting point (the peak temperature of the DSC curve) of from 130.degree. C. to 210.degree. C. containing from 5 to 40% by weight inorganic fine powders having a mean particle size of from 0.01 to 10 .mu.m as a base material layer (A) having adhered to at least one surface thereof a uniaxially stretched layer (B) having a surface roughness of from 0.3 to 1.5 .mu.m, with the uniaxially stretched layer (B) comprising a propylene .alpha.-olefin copolymer or a high-density polyethylene having a melting point (the peak temperature of the DSC curve) of from 120.degree. C. to 160.degree. C. which is at least 5.degree. C. lower than the melting point of the olefinic polymer of the base material layer (A) and from 8 to 65% by weight inorganic fine powders having a mean particle size of from 0.01 to 5 .mu.m, wherein the surfaces of the inorganic fine powders contained in the uniaxially stretched layer (B) are coated with the propylene .alpha.-olefin copolymer or the high-density polyethylene.
