Abstract:
A web of multi-dose cleaning products and method of manufacturing the same is disclosed. The web includes a carrier sheet including first and second pluralities of depressions, a first plurality of pouches, and a second plurality of pouches. Each of the pouches is positioned in a respective depression in the carrier sheet. The first plurality of pouches contain a first cleaning composition, and the second plurality of pouches contain a second cleaning composition. A first end of the carrier sheet is folded over a second end of the carrier sheet so that each multi-dose cleaning product is defined by at least an overlapping pair of the first and second pouches and an overlapping pair of the first and second depressions.
Abstract:
A water-soluble film, comprising a first water-soluble film, wherein the first water soluble film disintegrates in water within less than about 24 hours and dissolves in water within less than about 48 hours as measured by the MSTM-205 at 20° C. The disclosure provides a water-soluble film comprising a first water-soluble film that disintegrates in water within less than 24 hours and dissolves in water within less than 48 hours as measured by MSTM-205 at 20° C. The first water-soluble film optionally may be further characterized in that it does not disintegrate in water for at least about 1 hour and does not dissolve in water for at least about 1 hour as measured by MSTM-205 at 20° C. The disclosure further provides a water-soluble film comprising a first water-soluble film characterized in that the degradation and/or dissolution of the first water-soluble film is adapted to be activated by consumer handling.
Abstract:
Disclosed herein are capsules for delayed release of an ingredient contained therein, in particular water-soluble capsules for delayed release of water-sensitive, gas-generating compositions, other gas-forming compositions, or other cleaning compositions into an aqueous liquid medium. The delayed release capsules can incorporate one or more gas-relief pinholes for gas-generating water-sensitive or other gas-forming compositions contained in the capsules, such as inorganic bleach or other alkaline compositions intended for delayed release into a wash medium during a laundry cycle or perfumes. The pinholes permit gas generated or otherwise formed within the capsule, such as due to exposure to environmental water vapor, to escape from the capsule interior, preventing pressure build-up and capsule deformation during storage. The pinholes are sized to prevent or otherwise substantially limit the passage of liquids when submerged in a liquid medium (e.g., liquid water in an aqueous liquid medium). Related articles and methods for delivering the capsules in combination with a detergent or other laundry composition are also disclosed.
Abstract:
Disclosed are plasticized, water-soluble films having favorable cold-water solubility, wet handling, and thermoforming characteristics, and which can include a PVOH resin made up of blend of two or more PVOH polymers each having a monomodal molecular weight distribution, and the PVOH resin characterized by a viscosity in a range of about 13.5 cP to about 20 cP (or a corresponding weight average molecular weight), a degree of hydrolysis of about 84% to about 92%, a polydispersity index value in a range of about 1 to about 5, a residual water content of about 4 wt. % to about 10 wt. %, and a Resin Selection Index value in a range of 0.255 to 0.315; methods of making the films; compositions including PVOH resins for making the films; and pouch and packet articles made from the films.
Abstract:
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.
Abstract:
A water-soluble, halogen-resistant film-forming composition useful for packaging water treatment products is disclosed. The film can include an acid-stable, water-soluble polyvinyl alcohol polymer, an oxidizable organic material, a chelating agent, a free radical scavenger, and secondary additives such as plasticizers, lubricants, and surfactants. The resulting film has favorable solubility properties after having been exposed to halogenated (e.g., chlorinated and brominated) compositions such as water treatment and agricultural products for prolonged periods of time.
Abstract:
An edible film useful for packaging food additives is disclosed. The film generally includes an edible film-forming resin, a plasticizer, a compatibilizer, and optional secondary additives. The resulting edible film has favorable heat seal properties, being able to form an acceptable heat seal over temperature ranges of at least about 10° C.
Abstract:
Provided herein are water-soluble films comprising a water soluble polymer such as polyvinyl alcohol (PVOH) and high content of water-soluble starch, and related water-soluble film forming solutions, articles made therefrom e.g., pouches or packets, and methods of preparation and use of same.
