Degradable vegetable fiber packaging bag and preparation method thereof

Patent Name Degradable Plant Fiber Packing Bag and Its Preparation Method Patent Applicant Xu Hua Principal Applicant Address 200442 Room 202, Block 1, 201 Building, Hualing Road, Dahua Xincun, Shanghai, China Inventor Xu Hua Application (Patent) No. 200410016217.8 Date of Application 2004.02 .11 Approval Date Approval Notice No. 1654197 Date of Validation Notice 2005.08.17 Instruction CD-ROM D0533 Main Classification Number B31B19/00 Classification Number B31B19/00; D21B1/16; D21F1/00; D21H11/12 Distribution Original Priority Number Abstract The present invention relates to a degradable vegetable fiber packaging bag and a preparation method thereof, using plant fiber as a main raw material, (1) recycling wheat straw, storing it in a pit of a cement brick wall structure, and containing 40% lime And lime water of 60% water is injected into the pit so that the wheat straw is soaked in the lime water, and then the plastic pit covers the pit; the wheat straw and the lime water generate a chemical reaction in the pit, and the sebum of the wheat straw is removed automatically; Wheat straw, ground by a refiner slurry, into the slurry pool back. (2) Select the cotton yarn and woven it into a mesh roll cloth with a weaving machine. (3) An ordinary paper machine is used to convey the above slurry to the feed trough of the paper machine so that the slurry gradually flows into two rollers at the front end of the paper machine, and at the same time, the woven cotton gauze is transported to the middle of two rollers. The two rollers sandwich the cotton gauze in the slurry that is gradually fed in, so that the cotton gauze is combined with the slurry, and then the filter paper and the drying system are used to make the blank paper. (4) Cut the blank paper to make a roll blank and make a packaging bag. Disposal after use of this package can be naturally degraded, which is conducive to environmental protection. Sovereignty items 1. A degradable plant fiber packaging bag and a preparation method thereof, characterized in that the plant fiber is used, and wheat straw, ie, straw, beech grass, reed, bamboo and cotton are used, and one or more kinds of plant fibers are used The main raw materials are prepared according to the following methods: (1) The remaining wheat straw after wheat harvesting is collected and stored in a pit of a cement brick wall structure, and lime water containing 40% lime and 60% water is injected into the ground. In the pit, the wheat straw is soaked in lime water, and then it is sealed with a plastic film to make it impermeable; wheat straw and lime water react chemically in the pit, and the sebum of wheat straw is stripped off by itself. The degreasing process takes 7 to 10 days; the wheat straw soaked in the lime water is taken out of the pit, grinded into slurry by a refiner, and put into the slurry pool for use; the yarrow, reed, and bamboo are also used. In the same way, degreasing and refining are carried out. Before the degreasing of bamboo, the surface of the bamboo is to be shaved to form bamboo fiber; (2) the cotton yarn is selected, and the fabric is woven into a web-like roll cloth; (3) The above-mentioned pulp is used in an ordinary paper machine. The material is conveyed to the feeder of the paper machine so that The material gradually flows into the two rollers at the front end of the paper machine. At the same time, the woven cotton gauze is transported to the middle of two rollers. The two rollers sandwich the cotton gauze among the gradually-input pulp, making the cotton gauze and Slurry is put together, and then it enters the water filtration and drying system together, and the blank paper is made by flattening and drying. (4) The blank paper is cut according to the size of the required sack shape, and the automatic folding machine is used. The automatic folding machine is used to make the sewing machine to make the billets. According to the size specifications of the pouch, the upper and lower bags of the pouches are sealed to form a rectangular shape, and then the redundant portions of the pouches are cut off. A degradable plant fiber sack-shaped packaging bag is thus formed. International Application International Publication Entering Country Date Patent Agency Shanghai Patent & Trademark Office Co., Ltd.
