[0024] A breathable wrapping paper is prepared from 73% by mass of slurry, 37% of modified fiber solution, and 3% of papermaking auxiliary agent. Among them, the slurry is mixed with 40% by mass of wood pulp and 60% by mass of bamboo pulp; the fiber solution is composed of 20% by mass of modified polyester fiber solution and 80% by mass of modified polyester fiber. Lactic acid fiber solution is mixed.

[0025] A method for preparing air-permeable wrapping paper, comprising the following steps:

[0026] Step 1. Fiber modification treatment: a. Add water to the polyester fiber to form a 5% solution, add 1% chitosan, and use a deflagging machine with a gear speed of 2000r / min for 30 minutes, and then use a machine with a speed of 250r / min. Refining with a refiner for 15 minutes to obtain a modified polyester fiber solution; b. add water to the polylactic acid fiber to form a 10% solution, add sodium alginate with a mass percentage of 10%, and use a mixer with a rotation speed of...

Abstract

The invention belongs to the field of special paper and specifically relates to air-permeable packaging paper and a preparation method thereof. The air-permeable packaging paper is prepared from the following materials in percentage by mass: 60-90% of pulp, 4-37% of fiber solution and 0.03-3% of a papermaking additive. The preparation method of the air-permeable packaging paper comprises the following steps: fiber modification, papermaking, gluing and drying. According to the preparation method, the air-permeable packaging paper capable of guaranteeing medical equipment under sterile state inthe whole life cycle can be made through modification of a fiber solution. The air-permeable packaging paper not only can meet the requirement of sterilizing packaged products by penetrating through paper but also can screen the invasion of external bacteria and achieve a bacteria-blocking effect.

Description

technical field [0001] The invention belongs to the field of special paper, and in particular relates to an air-permeable wrapping paper and a preparation method thereof. Background technique [0002] In order to regulate the production and use of medical consumables, the State Drug Administration promulgated the "Supervision and Management Measures for Disposable Sterile Medical Devices", which put forward higher requirements for the disposable packaging of medical consumables, requiring Wrapping paper not only meets certain strength and sterility, but also has good air permeability. [0003] The aseptic packaging papers on the market all have the defects of poor air permeability and poor antibacterial effect, making it difficult to ensure the sterility of medical consumables throughout their life cycle. The invention patent with the publication number CN1528978A discloses a waterproof and air-permeable paper, which is prepared from fiber pulp and heavy oil. The wrapping p...
