To provide a stretched film of void-containing thermoplastic resin having an attractive force between sheets is 50 g or less. The stretched film of void-containing thermoplastic resin has no charge therein and can be processed secondarily with lesser electrostatic disturbance even in a low-humidity environment.

Stretched film of void-containing thermoplastic resin and process for producing the same

The invention provides a label for in-mold forming which tenaciously adheres to molded articles regardless of the materials of the molded articles, is usable under a wide range of molded-article molding conditions, and has an excellent print finish. The invention relates to: a label for in-mold forming, which comprises a resin film comprising a heat-sealable layer and a printing layer, wherein the heat-sealable layer has a rate of surface aperture of 6-30%, the printing layer has a dot skipping of 5% or lower, and the printing layer has a Bekk's surface smoothness (JIS-P-8119) of 650-20,000 seconds; and a molded article using the label.

In-mold molding label and molded product using the same

Disclosed is a stretched resin film having a liquid absorption coefficient of at least 5 ml/(m&#xb7;ms). The stretched resin film has good liquid absorbability with good seepage resistance. When stuck to objects with a water-base adhesive, it dries within a short period of time and attains good adhesiveness.

Stretched resin film and label comprising the same

A label for in-mold formation is provided which can be readily delaminated from the container by any one because of its excellent delamination initiation property and delamination transmission property as well as its low interlaminar strength, and which can be recorded with information such as pictures and letters on the inner side concealed by the label, and therefore, enabling effective utilization of the display area, or utilization of the delaminated label portion as a request form or a discount ticket, so called coupon. The present invention discloses a label for in-mold formation which includes a base layer (A) containing a thermoplastic resin, a layer (B) which enables delamination, and a heat seal layer (D) in this order; the aforementioned label for in-mold formation which includes an intermediate layer (C) between the layer (B) which enables delamination and the heat seal layer (D); and a resin molded product with a label to which the label for in-mold formation is attached to integrate with such a resin molded product by thermal fusion.

Label for in-mold formation

The invention relates to: a label for in-mold forming having excellent suitability for delabeling which comprises a thermoplastic resin film base layer (I) and a heat-sealable resin layer (II) and in which the heat-sealable resin layer (II) has an adhesion strength as measured at 23&#xb0; C. of 300 gf/15 mm or higher and an adhesion strength as measured at 90&#xb0; C. of 290 gf/15 mm or lower; and a labeled resin container having the label bonded thereto.

Label for in-mold forming having excellent delabeling property, and container with the label

Disclosed is an in-mold labeled thermoplastic resin container specifically so designed that the ratio of the product A of the Gurley stiffness (m&#xb7;kgf) and the 3% elongation load (kgf) of the label-edge part of the labeled area thereof to the product B of the Gurley stiffness and the 3% elongation load of the label-surrounding part of the non-labeled area thereof, A/B, is at most 0.6. The container has good drop impact fracture resistance and has good producibility, and it is lightweight.

Labeled resin container

The object of the present invention is to provide a biodegradable label for in-mold forming, which is excellent in water resistance, is printable to allow for printing letters, or the like, by various printing methods, and is biodegradable in a natural environment; and to provide a biodegradable container attached with this biodegradable label for in-mold forming. In the present invention, the gist of the first invention is a biodegradable label for in-mold forming, comprising a laminate film (a/b), having a film (a), comprising a biodegradable resin (A), and a film (b), comprising a heat-sealable biodegradable resin (B); and the gist of the second invention is a biodegradable container attached with this biodegradable label for in-mold forming.

Biodegradable label for in-mold forming and biodegradable container having the label attached thereto

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.
