A radiative cooling film and a product thereof are provided. The radiative cooling film includes a carrier layer, a reflective layer and an emissive layer stacked together. A light shines on the radiative cooling film from the emissive layer. The emissive layer includes a polymer containing a CF bond. The carrier layer includes a polymer containing at least one of a CC bond and a CO bond. After disposing at 120 degrees centigrade for 30 minutes, a transverse direction heat-shrinkage rate of the carrier layer is less than or equal to 2%, and a machine direction heat-shrinkage rate of the carrier layer is less than or equal to 3%. A thickness of the radiative cooling film is in a range of 50 m to 170 m, and a thickness of the emissive layer accounts for 20% to 90% of the thickness of the radiative cooling film.

The invention relates to providing a method for obtaining a multilayer film for thermally inducible shrink labels, products thereof and use of such products. The invention provides a multilayer film for labelling, the multilayer film comprising a first skin layer, a second skin layer and a core layer between the first skin layer and the second skin layer, wherein at least one of the first skin layer and the second skin layer comprises cyclic olefin copolymer and the core layer comprises copolymer of ethylene and butyl acrylate or propylene terpolymer.

The present invention provides a multilayer packaging film characterized by an improved sealability even through contamination with excellent shrinkability good optics and strength without using internal layers of stiff resins and cross-linking, to flexible containers made therefrom, such as bags, pouches and the like, useful for packaging articles, in particular food items.

A method may include placing a bottom facer on a conveyor, placing a core layer on the bottom facer placing a top facer on the core layer, and pressing the bottom facer, the core layer, and the top facer in a hot press to form a panel, wherein the hot press causes the bottom facer to shrink relative to the top facer, introducing a warp into the panel such that, when installed, the warp compensates for an installation warp and the panel is flat upon installation.

A thermoplastic pipe and a method for producing a thermoplastic pipe are provided. The thermoplastic pipe includes a liner layer, a semi-consolidated core layer comprising a prepreg polymeric fabric layer, and a shrink wrap outer layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is randomly distributed across the fabric. The method includes producing a hollow inner liner layer, winding a prepreg comprising a polymeric powder scattered on a fabric over the hollow inner liner layer to produce a core layer, covering the core layer in a heat shrinkable wrap, and heating to produce a semi-consolidated core layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is randomly distributed across the fabric.

A laminate film, package formed from the laminate film, and method for constructing the laminate film are provided. The laminate film includes a barrier layer, sealing layer, bonding layer, and thermochromic ink layer. The thermochromic ink layer includes thermochromic ink such that the thermochromic ink is trapped between the barrier layer and sealing layer. The thermochromic ink has a first visual appearance and is adapted to permanently change to a second visual appearance upon exposure to certain pre-determined conditions during a sealing process and to maintain permanence of the second visual appearance during post-sealing processes. The package includes the laminate film, a substrate, and a packaged article. The edges of the laminate film are sealed to the substrate and form a seal. The seal forms a perimeter about the article and has the second visual appearance, including a different color, such that the integrity of the seal is quickly and confidently verifiable by an observer.

A glass substrate comprises a glass clad layer fused to a glass core layer. The glass core layer comprises a core glass composition having an average core coefficient of thermal expansion (CTE.sub.core) and the glass clad layer comprises a clad glass composition having an average clad coefficient of thermal expansion (CTE.sub.clad) that is less than the CTE.sub.core. A maximum tensile stress in the glass core layer is less than 15 MPa.
