This disclosure is related to the field of polymer interlayers for multiple layer glass panels and multiple layer glass panels having at least one polymer interlayer sheet. Specifically, this disclosure is related to the field of polymer interlayers comprising multiple thermoplastic layers which resist the formation of optical defects.

Disclosed herein are sealing solutions for sealing water-soluble films, in particular aqueous mixtures including one or more polymeric solvents such as polyols. Aqueous sealing solutions including a relatively dilute solvent for one or more polymeric components of the water-soluble film (e.g., water-soluble polymeric components thereof, such as polyvinyl alcohol (PVOH)) can exhibit one or more benefits, including a reduction in dissolution of the film by the sealing solution and an increase in seal strength. Also disclosed are sealed articles formed with the sealing solutions, for example water-soluble packets containing various liquid or solid compositions.

A sachet product that includes a biodegradable and/or home compostable sachet comprising a front film and a back film. In some examples, the front film and back film can include a middle layer that can contain paper with greater than 85% cellulose and an inner layer that can include different material, including but not limited to polyvinyl alcohol or polyhydroxylalkonate. The sachet can include a compartment adapted for storing a solid article where the solid article is an open cell foam. The open cell foam can include a water-soluble polymer and a surfactant.

A method of manufacturing a coextruded and/or laminated and biaxially oriented composite film and a resulting multilayered film which has improved processability and/or improved recyclability. For this purpose, the method and multilayered film provides a novel combination of the density of various layer components of the composite film and certain manufacturing parameters such as the stretching factors, relaxation factors, relaxation temperatures, and residual stretching factors.

A recording medium, including: an ink-receiving layer configured to receive an ink for inkjet recording; and a transparent sheet having a total luminous transmittance of 50% or more, wherein the recoding medium has a layered structure in which the transparent sheet and the ink-receiving layer are sequentially stacked, and the ink-receiving layer includes a gap-absorption-type ink-receiving layer including a composition including at least inorganic fine particles and polyvinyl alcohol having a weight-average polymerization degree of 2,000 or more and 5,000 or less and a saponification degree of 70 mol % or more and 90 mol % or less.

A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms, c)at least one crosslinking agent. A method of production and use thereof.

Polyester-based films contain certain copolyesters (A) and polyester plasticizers (B). The copolyesters (A) may be selected from those in which the force required to stretch a film of the copolyester (A) by itself, from 2× to 5×, increases by less than 200%. The polyester plasticizers (B) have a weight-average molecular weight of 900 to 12,000 g/mol, and contain (i) a diol component comprising residues of diols having 2 to 8 carbon atoms, and (ii) a diacid component comprising residues of dicarboxylic acids having 4 to 12 carbon atoms. These polyester-based films are particularly useful for preparing ultra-thin LCD or OLED polarizers, because they can be stretched very thin with a high stretch ratio at lower temperatures.

The present invention relates to the technical field of agricultural films and in particular refers to a multilayer plastic film for agricultural applications comprising light-emission shifting properties. Furthermore, the present invention relates to the use of the multilayer plastic film for, in particular perennial, agricultural applications.

A sealing film suitable for food packaging is disclosed, which adopts the following solution. The sealing film comprises, in sequence, a PET layer, a VMPET layer and a PE layer from outside to inside, wherein the PE layer comprises 100-110 parts of PE, 15-20 parts of EVA, 15-20 parts of EAA, 55-60 parts of HDPE and 10-15 parts of LLDPE in parts by mass. In this manner, the addition of HDPE and LLDPE into the PE layer is intended to enhance the tensile strength of the sealing film.
