摘要:
A labeled resin bottle containing a resin bottle and one or more labels placed thereon and fused therewith, wherein said resin bottle has a value of W/(V⅔) within a range from 0.1 to 0.5 m, wherein W is a base weight, and V is a fill-in volume, provided that when the value is 0.1 or larger and smaller than 0.3, the bottle has a major thick layer consisting of a polyolefinic resin having a stiffness of 5,000 kgf/cm2 or below, and wherein said label has a tensile elastic modulus of 5,000 to 30,000 kgf/cm2. The labeled resin bottle is capable of withstanding reduced bottle strength while thinning the resin bottle and reducing the amount of source resins used therefor.

摘要:
An in-mold label includes a thermoplastic resin film substrate layer and a heat-seal resin layer. The label has a label body and a separable part. Tearable perforations are provided between the label body and the separable part. The adhesion strength between the separable part and a thermoplastic resin container is from 80 to 270 gf/10 mm, when the label is stuck to the container during in-mold production of the container. A lubricant is applied to from 55 to 80% of the surface area of the heat-seal resin layer of the separable part. The wettability index of both the thermoplastic resin film substrate layer surface and the heat-seal resin layer surface is from 34 to 73 mN/m.
