The present disclosure is directed to providing a self-adhesive foamed laminate sheet which is excellent in air escapability even after exposure to heat and pressure. The self-adhesive foamed laminate sheet of the present disclosure includes a synthetic paper substrate and a self-adhesive foamed sheet. The self-adhesive foamed sheet is formed from a composition for a self-adhesive foamed sheet including a polymer, a crosslinking agent, and a wax agent.

Self-adhesive foamed laminate sheet

The present disclosure is directed to provide a package which enables repeated opening and sealing of an opening, and can be favorably closed by bringing a pair of resin adhesive parts into contact with each other while preventing sticking of materials to each resin adhesive part. A package of the present disclosure comprises a main body having an internal space and an opening in communication between the internal space and an outside; and a pair of, i.e., two, resin adhesive parts which are disposed so as to be capable of being brought into contact with each other for sealing the opening. Here, the 90-degree peel force between the pair of resin adhesive parts is 0.02 N or more, the coefficient of dynamic friction of each of the two resin adhesive parts is 1.50 or less, and the tack force of each of the two resin adhesive parts is 1.60 N or less.

Package

Provided is a laminated sheet including an upper paper layer and a release sheet layer, the upper paper layer including synthetic paper and an adsorbing layer, the synthetic paper, the adsorbing layer and the release sheet layer, in order, being laminated, wherein the adsorbing layer is a foam sheet of a resin composition, the resin composition containing crosslinking resultant of 100 parts by mass of a (meth)acrylic acid ester copolymer resin and 1 to 20 parts by mass of a carbodiimide crosslinking agent, the (meth)acrylic acid ester copolymer resin having a N-methylol group, a glass transition temperature of the (meth)acrylic acid ester copolymer resin being no more than &#x2212;10&#xb0; C., the release sheet layer consists of a thermoplastic resin sheet, and a rate of tensile elastic moduli is 0.1 to 10, the rate being calculated from a tensile elastic modulus of the upper paper layer and a tensile elastic modulus of the release sheet layer, and a peel strength of the adsorbing layer and the release sheet layer is 5 to 30 N/m, the laminated sheet using a new foamed resin layer having well-balanced properties, the amount of formaldehyde emitted from which is extremely small, as the adsorbing layer, the release sheet and the adsorbing layer having a proper release force.

Laminated sheet and method for producing the same

Under a thermomechanical analysis with heating from a room temperature to 150&#xb0; C., &#x3b1; is in a range of from &#x2212;2.5 to 2.5 percent, and &#x3b1;-&#x3b2; is in a range of from &#x2212;1.5 to 1.5 percent, where &#x3b1; is a ratio of a dimension of the thermoplastic resin sheet (A) after the heating to a dimension of the thermoplastic resin sheet (A) before the heating, and &#x3b2; is a ratio of a dimension of the release paper (C) after the heating to a dimension of the release paper (C) before the heating.

Electrophotographic recording sheet and label paper

A pressure-sensitive adhesion-processed sheet which can be easily stuck without forming blisters by air-entrapment, is less expensive, can be easily re-stuck, and has favorable working characteristics. The pressure-sensitive adhesion-processed sheet includes a sheet base material and a pressure-sensitive adhesive layer having plural small valleys and plural small peaks.

Pressure-sensitive adhesion-processed sheet

The object of the invention is to provide an electrophotography recording paper having excellent density, color tone, gradation, fixing properties and recording qualities, while having excellent water resistance and durability. The object may be obtained by constructing an electrophotography recording paperby laminating a recording layercomprising a synthetic resin film having a coating layeron at least one side of a base material layercomprising a paper material having a water resistance. The electrostatic capacity of the electrophotography recording paper is controlled at 10 pF/cmor more. It is desirable that the synthetic resin film as the recording layerbe a polyester film, particularly a polyethylene terephthalate film.

Electrophotography recording paper
