Abstract: This invention relates to a water-degradable flexible bag for carrying goods purchased from retailers or wholesalers, and/or for packing consumer goods or hygienic products, comprised of at least two parallel walls bonded in their upper section by at least one sealing band in each side edge, a sealing band bonding the lower ends of the parallel walls and an opening at the end, opposite to the sealing band, wherein each of the parallel walls consists of a nonwoven polyvinyl alcohol resin fabric. In a different embodiment, the invention also relates to a water-degradable flexible gurney cover for covering patient care gurneys, wherein said gurney cover consists of a nonwoven polyvinyl alcohol resin fabric.

Abstract: The present invention describes a detergent composition in the form of a flexible sheet, which in turn is soluble in water, and the water-soluble detergent sheet. Said detergent composition in the form of a flexible sheet comprises a unique mixture of components, including: a water-soluble polymeric component, an anionic surfactant, a non-ionic surfactant, water and other components. Once mixed in the appropriate proportions, the components produce a flexible sheet with detergent characteristics that can be incorporated directly into a clothes-washing recipient, said recipient ranging from a simple bowl to an advanced automatic washing machine. Once the detergent sheet comes into contact with water inside the washing recipient, the sheet dissolves and releases the active ingredients and complementary ingredients contained therein.

Abstract: A water-soluble shopping bag and a preparation method thereof. The water-soluble shopping bag consists of the following components according to the following parts by weight: 100 parts of polyvinyl alcohol, 8-20 parts of a composite plasticizer; 10-30 parts of a polysaccharide and the derivative thereof; 1-5 parts of a processing aid, 0.1-0.5 parts of a film slipping agent and 0.5-3.0 parts of a film anti-blocking agent. The preparation method comprises the following steps: mixing the components according to the parts by weight, extruding the mixture to form pellets after mixing, then performing blow molding to form a film, and then preparing various types and sizes of water-soluble shopping bags. The water-soluble shopping bag has higher bearing capacity and cold water solubility, is suitable for use in water-free environment, and dissolves upon contacting water without producing pollution after being used.
