Sachets composed of metal barrier layers that can include both a sealant and an external protective coating material. The sealant provides heat sealing, and product formulation protection properties, while the barrier material functions to reduce the moisture vapor transmission rate (MVTR) into or out of the sachet.

A laminate comprising a heat-resistant polymer film, an inorganic substrate, and a polyamine compound layer formed using a polyamine compound, wherein the polyamine compound layer is formed between the heat-resistant polymer film and the inorganic substrate.

To ease and improve the production of objects, a method is described for producing an object (60) comprising a structural core (10) and an outer coating of polymeric material (52), comprising the steps of (i) coating with polymeric material (50) a lamina (10), wherein the lamina comprises a surface exhibiting macroscopic discontinuities (32) configured so that the polymeric material grips to them in order to form a multilayered piece; (ii) removing parts from the multilayer piece to obtain a contour corresponding to the object, the contour comprising an edge (B) along which a margin of the lamina remains uncovered by the polymeric material.

The present invention provides a decorative sheet having excellent work characteristics, weather resistance, and scratch resistance and a decorative material using the same. Disclosed are a decorative sheet including a base material and a surface-protecting layer, wherein at least one of the base material and the surface-protecting layer contains a white pigment, the surface-protecting layer is a cured product of a curable resin composition, and a Martens hardness of the decorative sheet is 9 N/mm.sup.2 or more and 25 N/mm.sup.2 or less; and a decorative material using the same.

A multilayer structure comprising solid layers and defining at least one gap that separates the solid layers to form an alternating pattern of the solid layers and the at least one gap in the structure.

Provided is a PSA sheet capable of suitably preventing bubble formation caused by outgassing. This invention provides a PSA sheet comprising a PSA layer that forms an adhesive face. In an aging test where the adhesive face is press-bonded to a glass plate and stored at 50° C. for 24 hours, the PSA sheet has at least 5% post-aging non-bonding area Sa, with Sa defined as the ratio of all areas non-bonding to the glass plate relative to the total area of the adhesive face. The non-bonding areas have parts linearly extending along the adhesive face.

Described are compositions comprising a defoamer mixture comprising mineral oil and hydrophobic particles such as for example wax particles; di- or monoalkyl sulfosuccinate having at least 9 carbon atoms in the alkyl group and certain ethylene oxide/propylene oxide block copolymers. Also described are aqueous dispersions of hydrophobic polymers comprising these compositions and the use of the aqueous polymer dispersions as an adhesive, for example for producing composite films from transparent polymer films.

In one embodiment, a film is described comprising a mixture of semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) midpoint as measured by differential scanning calorimetry of at least 25° C.; and plasticizer; wherein the film is oriented. In another embodiment, a film is described comprising a mixture comprising semicrystalline polylactic acid polymer, polymer having a midpoint Tg as measured by differential scanning calorimetry of at least 25° C., and plasticizer; wherein the mixture exhibits a single midpoint Tg and the single midpoint Tg ranges from 40° C. to 65° C.; and wherein the film is oriented and the oriented film exhibits a higher midpoint Tg ranging from 40° C. to 65° C. and a lower midpoint Tg ranging from 5 to 25° C.

The present disclosure provides adhesive articles that can be removed from surfaces without damage by having reduced or eliminated contribution of a core backing to peel force generated by the adhesive during removal. In some instances, this can be accomplished by a core that loses structural integrity in a direction normal to a plane defined by a major surface. In other instances, the contribution is reduced by compromising the interface between the core and a peelable adhesive layer.

The present disclosure generally relates to adhesive compositions and articles including at least one of polydiorganosiloxane polyoxamide copolymer, silicone polyurea block copolymer, and/or an addition cure silicone, a silicate tackifying resin, and inorganic particle filler. The filler is typically fumed silica. Some embodiments of the adhesive composition include at least one of a polydiorganosiloxane polyoxamide copolymer, a silicate tackifying resin in an amount of between about 10 wt % and about 70 wt %, and inorganic particle filler in between about 0.1 wt % and about 20 wt %; a silicone polyurea block copolymer, a silicate tackifying resin in an amount of between about 10 wt % and about 70 wt %, and inorganic particle filler in an amount between about 0.1 wt % and about 20 wt %; and an addition cure silicone, a silicate tackifying resin in an amount of between about 10 wt % and about 70 wt %, and inorganic particle filler in an amount between about 0.1 wt % and about 20 wt %.
