Water-soluble polyvinyl alcohol blend film, related methods, and related articles

Disclosed herein are water-soluble films including a polyvinyl alcohol (PVOH) resin blend and optionally one or more additional components such as plasticizers, fillers, surfactants, and other additives. Also disclosed herein are articles including the water-soluble film and containing a composition such as a household care composition. The PVOH resin blend includes a PVOH copolymer including one or more types of anionic monomer units such as a PVOH terpolymer and a PVOH polymer such as a partially or completely hydrolyzed PVOH homopolymer. When the PVOH copolymer and PVOH polymer are blended in particular proportions and/or selected with regard to various criteria related to the 4% solution viscosity of one or both of the PVOH polymer(s) and PVOH copolymer(s), the resulting water-soluble film formed from the PVOH resin blend exhibits substantially improved aqueous dissolution properties.

FOOD PACKAGING, PARTICULARLY FOR DAIRY OR CHEESE PRODUCTS, AND ASSOCIATED MANUFACTURING METHOD
20200317436 · 2020-10-08 ·

The invention relates to a food packaging (10), particularly for milk or cheese products (20), comprising two hollow shells (12, 14), each of the two shells (12, 14) having a plane of symmetry (S) and extending to a predetermined depth (p12, p14) and having predetermined thickness (e), the joining plane (16) being substantially orthogonal to the plane of symmetry (S), said packaging being characterized by the fact that at least one of the two shells (12, 14) has a depth (p12, p14), measured in said plane of symmetry (S), that is greater than or equal to its thickness (e) measured in the joining plane (16). The invention also relates to a method of producing a food packaging (10), in particular for milk or cheese products (20).

STIRRER COMPRISING A SEALED PACKAGE WHICH HOLDS THEREIN A LIQUID
20200270043 · 2020-08-27 ·

There is provided a pack (10) in the form of a stirrer for a hot or cold beverage. The stirrer comprises first and second films (13, 14) sealingly connected around a periphery to enclose a volume in which is disposed a liquid. The liquid is conveniently disposed in an elongate channel (15) formed in one of the films. Openable portions (17, 55) are provided at respective ends of the stirrer, one openable portion (17) allowing the liquid to flow out once opened and the other openable portion (55) acting as a vent. Each openable portion is opened by peeling apart the two films and has a stronger connection (52, 57) provided to limit the opening of the ends.
