폴리비닐 알코올 (PVOH) 수지 블렌드 및 임의로 1종 이상의 추가의 성분 예컨대 가소제, 충전제, 계면활성제, 및 다른 첨가제를 포함하는 수용성 필름이 본원에 개시된다. 또한 수용성 필름, 및 가정용 케어 조성물과 같은 조성물을 포함하는 물품이 본원에 개시된다. PVOH 수지 블렌드는 하나 이상의 유형의 음이온성 모노머 단위를 포함하는 PVOH 코폴리머 예컨대 PVOH 삼원중합체, 및 PVOH 폴리머 예컨대 부분적으로 또는 완전히 가수분해된 PVOH 호모폴리머를 포함한다. PVOH 코폴리머 및 PVOH 폴리머가 특정 비율로 블렌딩되고/되거나 PVOH 폴리머(들) 및 PVOH 코폴리머(들) 중 하나 또는 둘 모두의 4% 용액 점도와 관련된 다양한 기준에 관련하여 선택될 때, PVOH 수지 블렌드로부터 형성된 수득한 수용성 필름은 실질적으로 개선된 수성 용해 특성을 나타낸다. 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.
