Disclosed are recyclable flexible package and a method of recycling such packages. The flexible package includes a hollow body defining an interior chamber for holding an oxygen sensitive product. The body is formed of a laminated film formed of two layers of a single polymer material, e.g., polyethylene, and at least one interposed barrier layer, e.g., polyvinyl alcohol, that is resistant to the passage of oxygen therethrough and which is water-soluble. The single polymer constitutes at least 95% by weight of the laminated film, whereupon the package is suitable for recycling without requiring separation of the materials thereof by shredding the laminated film and subjecting those pieces to an aqueous wash to dissolve the barrier layer.

The present disclosure relates to a multi-layered design for an article of apparel such as swimwear. In particular, at least one layer may include a stretch resistant matrix made of a thermoplastic polymer, a silicone or other similar material to provide additional support and modesty to certain areas of the apparel, such as the bust area. Further, a method of manufacturing the article of apparel is also disclosed. According to aspects described herein, the layers may be integrated using techniques to increase the overall integrity of the apparel.

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.

Precursors and methods for manufacturing perforated composite parts are disclosed. An exemplary precursor (19) comprises structural fibres (24,28) embedded in a cured matrix material (24,26) and interposed between two removable plies (20). The precursor may also comprise a sacrificial fibre (28) extending through the removable plies (20), the matrix material (24,26) and between the structural fibres (24,28). An exemplary method comprises removing the removable plies (20) from the precursor (19) and removing the sacrificial fibre (28) from the precursor after removing the removable plies to form a through hole in the precursor (19) at a location of the sacrificial fibre (28).

Films including a water-soluble layer and a vapor-deposited organic coating are disclosed. The films can optionally further include a vapor-deposited inorganic layer. The films exhibit enhanced barrier properties.

The present disclosure belongs to the technical field of disposable toilet seat covers, and in particular to a novel portable toilet seat cover. The novel portable toilet seat cover comprises more than one unit layers, each unit layer comprises a surface layer, and a base layer. The surface layer is arranged at a first surface of the base layer, and the bottom layer is arranged at a second surface of the base layer; the surface layer is a release layer for preventing skin adhesion.

A laminate composite material (1), suitable for the packaging of food products and having a multilayer structure comprising: a first outer layer (21) of paper or plastic film; an inner layer (22) of adhesive; and an intermediate layer (23) interposed between the first and the second layer and made of sodium silicate (Na.sub.2O×SiO.sub.2).

A cementitious composite includes a first layer, a second layer, and a cementitious mixture disposed between the first layer and the second layer. The cementitious mixture includes (i) cementitious materials and (ii) a viscosity modifier and/or an accelerator. The cementitious materials provide a void fraction between 0.64 and 1.35. The void fraction is defined as the ratio of the volume of the voids within the cementitious mixture per unit area of the cementitious composite to the volume of the cementitious materials per unit area of the cementitious composite. The cementitious mixture is configured to absorb a mass of water that provides a maximum 28 day compressive strength of the cementitious composite. A ratio of the mass of the water relative to the mass of the cementitious materials of the cementitious mixture per unit area of the cementitious composite that provides the maximum 28 day compressive strength of the cementitious composite is between 0.25 and 0.55.

A water-soluble film comprising an integrated water-dispersible barrier against any permeation.
