Problems solved by technology

At present, there are many kinds of medical wrapping papers used in the market, most of which are cheap wrapping papers. There is no medical wrapping paper specially designed for high-efficiency protection, especially for the anti-seepage technology. Packaging paper still has the problems of unsatisfactory anti-seepage effect, poor printing performance, low paper strength and low internal bond strength of paper

Abstract

The invention discloses anti-seepage medical wrapping paper. The anti-seepage medical wrapping paper comprises the following raw materials of, in percentage by mass, 30% of bleached sulfate softwood pulp, 45% of bleached sulfate hardwood pulp, 1% of casein, 2% of starch, 3% of soybean protein, 1% of polyvinyl alcohol, 3% of synthetic resin emulsion, 6% of polyvinyl alcohol, 4% of a binder, 5% of inorganic particles, 6% of a flatting agent, 2% of emulsified silicon oil, 2% of a higher alcohol fatty acid ester complex, 3% of polyoxyethylene polyoxypropylene pentaerythritol ether, 3% of polyoxyethylene polyoxy propanol amine, 1% of polyoxypropylene glycerol ether, 2% of polyoxypropylene polyoxyethylene glyceryl ether and 3% of polydimethylsiloxane. A production method of the anti-seepage medical wrapping paper comprises a first step of pulp mixing and blending, a second step of screen part dehydrating, a third step of sizing and a fourth step of drying treatment.

Description

technical field [0001] The invention relates to the technical field of wrapping paper technology, in particular to an anti-seepage liquid medical wrapping paper and a manufacturing method thereof. Background technique [0002] In the transportation process of medical devices, auxiliary materials and other products, due to the particularity of medical devices, auxiliary materials and other products, it is necessary to carry out efficient protection during the transportation of medical devices, auxiliary materials and other products. Therefore, it is necessary to use anti-seepage liquid medical packaging Paper protects medical devices, auxiliary materials and other products to ensure that they are corroded or polluted during transportation, which will affect the performance of medical devices, auxiliary materials and other products. At present, there are many kinds of medical wrapping papers used in the market, most of which are cheap wrapping papers. There is no medical wrapp...
