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.

Easy-open media wrapper

A structure is described for forming a wrapper, e.g., for print media, where the structure includes a line of weakness for facilitating a user's tearing of the wrapper to access the contents. The line of weakness may include a first line of weakness portion that extends along a fold line of an envelope fold forming one of the front or rear or right sides of the wrapped package, as well as a second line of weakness portion that extends substantially perpendicularly to the respective longitudinal fold lines and a connecting line of weakness portion that extends between the first line of weakness portion and the second line of weakness portion and is disposed at a non-zero angle with respect to each. In this way, a tear initiated near the first line of weakness portion and may be propagated along the other portions to create an opening for accessing the product.
