Embodiment 1

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

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

[0046] 2) Add nanocellulose to the slurry mixing tank, and add wet strength agent, dry strength agent and antibacterial agent, and carry out slurry mixing with the slurry in step 1); In the step 2), the weight ratio of each component is pulp: Nanocellulose: wet strength agent: dry strength agent: fungicide=100:2.5:1.2:0.6:0.015.

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

Embodiment 2

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

[0055] 1) Using imported kraft softwood pulp without fluorescent whitening agent, imported kraft hardwood pulp, and domestic bleached or unbleached aseptic bamboo pulp as fiber pulp, it is obtained after hydropulping and long-fiber viscous beating A slurry with a concentration of 7.0% and an average fiber number length of more than 1.5mm; said step 1) the beating degree is controlled at 60°SR, and the wet weight is required to be greater than 4.5g;

[0056] 2) Add nanocellulose to the slurry mixing tank, and add wet strength agent, dry strength agent and antibacterial agent, and carry out slurry mixing with the slurry in step 1); In the step 2), the weight ratio of each component is pulp: Nanocellulose: wet strength agent: dry strength agent: fungicide=100:4.0:0.8:1.0:0.01.

Abstract

According to the invention, sulfate softwood pulp, sulfate hardwood pulp and domestic bleached or natural-color sterile bamboo pulp are used as raw materials, nano-crystalline cellulose is added intopaper pulp, nano-crystalline cellulose is added into a surface sizing agent, and nano-crystalline cellulose is added into a surface coating solution, so that the strength of the paper is remarkably improved, the use experience of the paper is effectively improved, and the bad experience that food packaging paper such as hamburgers is broken, stuffing leaks out and oil seeps in the use process is prevented. Besides, through repulping, pulping and addition of various chemical additives meeting the GB9685-2016 standard, refined control over the technological process is improved, the high-temperature-resistant, oil-proof, anti-sticking and low-weight food packaging paper is prepared, traditional waxing paper and PE-coated paper materials can be replaced, and it is guaranteed that food making contact with the packaging paper 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 for foods such as hamburgers added with nanocellulose. Background technique [0002] Due to the rapid development of the food 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 changes in product structure for paper companies. Enterprises The key way of development and benefit is to use imported pulp board to develop and produce food wrapping paper with high added value such as white and natural color hamburger. [0003] At present, food packaging such as hamburgers mostly uses waxed paper, coated paper and other materials. Due to the impact of environmental degradation of wax and coated film; food migration safety hazards; fo...
