Abstract
Official abstract text for this publication.
Provided is a method for producing a self-adhesive to be arranged on a package comprising a space to store contents and an opening by which the space and an outside communicate, wherein the opening is repeatedly openable and sealable by the self-adhesive that consists of a cross-linking material of a resin composition containing a (meth)acrylic acid ester copolymer resin having a glass transition temperature of −22.8° C. or more, and a crosslinking agent. The method comprises making the resin composition that contains the (meth)acrylic acid ester copolymer resin, and the crosslinking agent, the resin composition being either emulsion or dispersion; and cross-linking the resin composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a self-adhesive to be arranged on a package comprising a space to store contents and an opening by which the space and an outside communicate, wherein the opening is repeatedly openable and sealable by the self-adhesive that consists of a cross-linking material of a resin composition containing a (meth)acrylic acid ester copolymer resin having a glass transition temperature of −22.8° C. or more, and a crosslinking agent, the method comprising: making the resin composition that contains the (meth)acrylic acid ester copolymer resin, and the crosslinking agent, the resin composition being either emulsion or dispersion, and the emulsion or dispersion having a viscosity of 3,500 to 5,500 mPa·s; and cross-linking the resin composition. 2. The method for producing a self-adhesive according to claim 1 , wherein said cross-linking is carried out on a surface of the package. 3. The method for producing a self-adhesive according to claim 1 , wherein said self-adhesive has a thickness of 0.03 mm to 3 mm. 4. The method for producing a self-adhesive according to claim 1 , wherein said self-adhesive has a density of 0.1 g/cm 3 to 1.0 g/cm 3 . 5. The method for producing a self-adhesive according to claim 1 , wherein the viscosity is measured at ambient temperature. 6. A method for producing a self-adhesive to be arranged on a package comprising a space to store contents and an opening by which the space and an outside communicate, wherein the opening is repeatedly openable and sealable by the self-adhesive that consists of a cross-linking material of a resin composition containing a (meth)acrylic acid ester copolymer resin having a glass transition temperature of −22.8° C. or more, and a crosslinking agent, the resin composition being a resin composition foam, the method comprising: making the resin composition that contains the (meth)acrylic acid ester copolymer resin, and the crosslinking agent, the resin composition being either emulsion or dispersion, and the emulsion or dispersion having a viscosity of 3,500 to 5,500 mPa·s; foaming the resin composition, to make the resin composition foam; and cross-linking the resin composition foam. 7. The method for producing a self-adhesive according to claim 6 , wherein said cross-linking is carried out on a surface of the package. 8. The method for producing a self-adhesive according to claim 6 , wherein said self-adhesive has a thickness of 0.03 mm to 3 mm. 9. The method for producing a self-adhesive according to claim 6 , wherein said self-adhesive has a density of 0.1 g/cm 3 to 1.0 g/cm 3 . 10. The method for producing a self-adhesive according to claim 6 , wherein the viscosity is measured at ambient temperature.
