A multi-layer packaging film structure is disclosed. This packaging film structure includes a barrier web made up of a barrier web core layer, a barrier web skin layer, and a packaging sealant layer. Each of the aforementioned film layers is biodegradable and/or compostable. At least one of the film layers is made up of at least 1 weight percent of poly(3-hydroxypropionate). The packaging film structure may also include a print web or a paperboard substrate.

The present invention is directed to a gypsum board and a method of making such gypsum board. In one embodiment, the gypsum board comprises a gypsum core including a first gypsum core layer and a second gypsum core layer sandwiching a laminate layer. The laminate layer comprises two outer laminate layers sandwiching an inner laminate layer, wherein the two outer laminate layers have a higher elastic modulus than the inner laminate layer. The method of making the gypsum board includes steps of providing facing materials and corresponding gypsum slurries wherein the laminate layer is provided in-line during the manufacturing process of the gypsum board.

This invention relates to a process for reducing or eliminating organoleptic degradation in organoleptically sensitive foods packaged in flexible packaging, and packaged products thereof. This invention also relates to organoleptic flexible packaging made from polymeric films comprising oxidation-stable and non-migratory polysiloxane as slip additive. The oxidative-stability and non-migratory nature of the polysiloxane slip additive provides an organoleptic flexible packaging that is non-interactive with and inert to the organoleptically sensitive food packaged within, specifically: (1) coffee; (2) beer; (3) water; and (4) wine.

A barrier film for electronic devices exhibiting and maintaining excellent water barrier property. The barrier film for electronic devices features a water permeability (23° C., RH50%) that is set to be not more than 10.sup.−4 g/m.sup.2/day and a water content that is maintained to be not more than 2000 ppm.

A display device includes a display panel including a folding area and a non-folding area which is adjacent to the folding area, a support member facing the folding area and the non-folding area of the display panel and having a total planar area, and a light shielding layer between the display panel and the support member and having a total planar area which is smaller than the total planar area of the support member.

A waterproof sound-transmitting sheet, which interposes an adhesive layer composed of a material having micropores formed therein, thus smoothing the flow of the air between a waterproof sound-transmitting layer and a support layer. The waterproof sound-transmitting sheet includes a waterproof sound-transmitting layer formed of a film having elasticity, an adhesive layer having one surface adhered to one surface of the waterproof sound-transmitting layer, and a support layer having one surface adhered to the other surface of the adhesive layer; and the adhesive layer includes a substrate having a pore formed therein and an adhesive agent formed on both surfaces of the substrate.

The disclosure is directed to methods of manufacturing protective packaging materials, as well as the protective packaging materials produced using the disclosed methods. These packaging materials can be biodegradable, compostable, and/or recyclable.

A description is given of a method of making film laminates using a lamination adhesive comprising (a) at least one acrylic polymer A with anhydride groups which are reactive with primary or secondary amine groups; and (b) at least one compound B with at least two amine groups selected from primary and secondary amine groups. The acrylic polymer A has a molecular weight of from 3000 to 50000 and the lamination adhesive is free of organic solvents, free of water and free of compounds with isocyanate groups.

A greenhouse has a daylighting member supported by a frame. The daylighting member partitions a growing space for agricultural products from an outside world, and emits light, which has entered from a light incident surface on one side, from a light emitting surface on the other side. The daylighting member has a transparent substrate layer and a transparent light emitting layer provided closer to a light emitting surface side than the substrate layer. The light emitting layer has a refractive index of 1.54 or less, water absorbability, and an equilibrium moisture content of 10% or greater at 25° C. and a relative humidity of 80%.
