Abstract

The invention provides a degradable water-soluble label material and a preparation method thereof. The degradable water-soluble label material comprises a modified polylactic acid film, soluble glue and release backing paper from top to bottom, the modified polylactic acid film comprises the following components: polylactic acid, modified plant cellulose fibers, polyethylene wax, and sodium stearate; wherein the modified plant cellulose fibers are plant cellulose fibers processed by hydrogen peroxide; and the preparation method of the soluble glue comprises the following steps: adding amylose,polyvinyl acetate and polyvinyl alcohol into water, adding calcium chloride, and heating to 120 DEG C until the volume density reaches 1.02-1.05 g/cm<3>.

Description

technical field [0001] The invention belongs to the field of film materials, and in particular relates to a degradable water-soluble label material and a preparation method thereof. Background technique [0002] Water-soluble label materials are widely used in candy wrapping, sticky cake liners, or made into sausage casings, and have a large market in the food industry; they can also be used in the mass consumer daily chemical industry. Water-soluble label materials need to be water-soluble, non-toxic, and capable of rapid degradation. Contents of the invention [0003] The invention provides a degradable water-soluble label material with impact resistance and a preparation method thereof, which solves the problem that current products cannot be degraded quickly and thus cause environmental pollution. It not only has the functions and characteristics of traditional labels, but also can be split and degraded in the natural environment through the action of microorganisms i...
