Embodiment Construction

[0017] A novel wrapping paper, made of the following components in parts by weight, 6 parts of glycerin, 40 parts of cornstarch, 8 parts of propylene glycol, 10 parts of glass fiber, 100 parts of fir powder, 4 parts of bentonite, 2 parts of citric acid fat; Made with the following crafting steps:

[0018] 1) Dissolve or disperse cornstarch in deionized water, stir at 55°C until it is completely gelatinized to obtain a cornstarch solution; add 40U / mL cellulase to the cornstarch solution, adjust the pH of the solution to 5.5, and Control the temperature to 60°C, react for 1.5 hours, adjust the pH value of the starch solution to 8.5, keep the temperature constant, add 80U / mL alkaline protease, and react for 3.5 hours to obtain the modified starch solution;

[0019] 2) Grind bentonite into powder, stir into 10 times the weight of clear water, mix well, add p-aminobenzoic acid and aminocaproic acid, adjust the temperature to 70°C, react for 2-3 hours, and dry, that is Obtain modif...

Abstract

The invention discloses novel packaging paper, which is prepared from the following components by weight: glycerin, corn starch, glass fibers, cunninghamia lanceolata powder and bentonite. According to the present invention, the novel packaging paper has advantages of wide raw materials, mild reaction, no toxicity, environmental protection and the like, and the green chemistry concept in the modern requirement is met; compared with the general packing paper, the produced packaging paper of the present invention has high tensile strength and high folding resistance, and is suitable for a variety of occasions; and the produced packaging paper has high printing adaptability, is suitable for a variety of surface printing, and further has characteristics of extremely high tensile resistance, complete degradation, and significant bacterial inhibition effect.

Description

technical field [0001] The invention relates to the field of paper production, in particular to a novel wrapping paper. Background technique [0002] Wrapping paper refers to the paper used for packaging with high strength, low moisture content, low air permeability, no corrosion, certain water resistance, and beautiful to use. The paper used for food packaging also requires hygiene, sterility, and Contamination impurities, etc. Paper and cardboard have always been the dominant materials in packaging materials, accounting for more than 40% of the packaging materials used. However, traditional paper and cardboard have low tensile strength and folding endurance, and are easily damaged by the packaged items, resulting in the failure of transportation. Contents of the invention [0003] The object of the present invention is to provide a new type of wrapping paper. [0004] The present invention is realized through the following technical solutions: [0005] A novel wrappi...
