Embodiment 1

[0044] A kind of manufacture method of the low-quantity food wrapping paper that adds nanocellulose, it is characterized in that, comprises the following steps:

[0045]1) Using imported sulphate softwood pulp, imported sulphate hardwood pulp and domestic bleached or natural aseptic bamboo pulp without fluorescent whitening agent as fiber pulp, it is obtained after hydropulping and long-fiber viscous beating treatment. The pulp with a concentration of 5.5% and a fiber number average length of more than 1.5 mm; the step 1) the beating degree is controlled at 70°SR, and the wet weight is required to be greater than 4.5g;

[0046] 2) adding nanocellulose to the mixing tank, and adding a wet strength agent, a dry strength agent and an antibacterial agent, and mixing with the slurry in step 1); the weight ratio of each component in the step 2) is pulp: Nanocellulose: wet strength agent: dry strength agent: bactericide = 100:2.5:1.2:0.6:0.015.

[0047] 3) Purify and screen after pu...

Embodiment 2

[0054] A kind of manufacture method of the low-quantity food wrapping paper that adds nanocellulose, is characterized in that, comprises the following steps:

[0055] 1) Using imported sulphate softwood pulp, imported sulphate hardwood pulp and domestic bleached or natural aseptic bamboo pulp without fluorescent whitening agent as fiber pulp, it is obtained after hydropulping and long-fiber viscous beating treatment. Slurry with a concentration of 7.0% and a fiber number-average length of more than 1.5mm; the step 1) beating degree is controlled at 60°SR, and the wet weight requirement is greater than 4.5g;

Embodiment 3

[0064] A kind of manufacture method of the low-quantity food wrapping paper that adds nanocellulose, is characterized in that, comprises the following steps:

[0065] 1) Using imported sulphate softwood pulp, imported sulphate hardwood pulp and domestic bleached or natural aseptic bamboo pulp without fluorescent whitening agent as fiber pulp, it is obtained after hydropulping and long-fiber viscous beating treatment. The slurry with a concentration of 6.5% and a fiber number average length of more than 1.5mm; the step 1) the beating degree is controlled at 65°SR, and the wet weight requirement is greater than 4.5g;

[0066] 2) adding nanocellulose to the mixing tank, and adding a wet strength agent, a dry strength agent and an antibacterial agent, and mixing with the slurry in step 1); the weight ratio of each component in the step 2) is pulp: Nanocellulose: wet strength agent: dry strength agent: bactericide = 100:3.0:1.0:0.8:0.013.

Abstract

The present invention selects kraft softwood pulp, kraft hardwood pulp and domestic bleached or uncolored aseptic bamboo pulp as raw materials, adds nano-cellulose to the pulp, adds nano-cellulose to the surface sizing agent, and surface-coats Nano-cellulose is added to the liquid, thereby significantly improving the strength of the paper, effectively improving the use experience of the paper and preventing the breakage of food packaging paper such as hamburgers during use, leakage of fillings, oil leakage and other bad experiences. In addition, through pulping, beating, and adding various chemical additives that meet the GB9685-2016 standard, the fine control of the process flow has been improved, and a low-weight food packaging paper with high temperature resistance, oil resistance, anti-sticking, and anti-sticking has been prepared. It can replace traditional waxed paper and coated paper materials to ensure that the food in contact with it is healthier, safer and more environmentally friendly.

Description

technical field [0001] The invention relates to food wrapping paper, in particular to a low-quantity inner wrapping paper added with nanocellulose and used for foods such as hamburgers. Background technique [0002] Due to the rapid development of the food and consumer goods industry, it provides a good opportunity for the development of packaging materials. The research and development and production of food-grade packaging paper products with safety, environmental protection, sustainable development and high added value are the current papermaking enterprises to change the product structure. The key way to develop and benefit is to use imported pulp board to develop and produce high value-added white, natural hamburger and other food packaging paper, which is a product that conforms to the current research and development, production, development, benefit, and social responsibility concepts of papermaking enterprises. [0003] At present, food packaging such as hamburgers ...
