Description
Technical field
The invention belongs to wrapping paper fields, and in particular to a kind of tealeaves fragrance wrapping paper and its preparation process.
Background technique
The main purpose of tealeaves fragrance wrapping paper is that tea culture is introduced into paper, so that common wrapping paper reflects
The form and taste of tealeaves enhance comforts of use and interest, while can guarantee that cosmetics, food etc. are being store as commodity
Fortune and the hygienic quality in use process and quality and flavor.
Therefore tealeaves fragrance wrapping paper that is beautiful, meeting cosmetics, food packaging safety requirement is developed, makeup can be met
Product, food packaging safety hygienic requirements, while promoting the security level of cosmetics, food packaging, have higher economic benefit and
Social benefit.
About tealeaves fragrance wrapping paper, there is not been reported on the market at present.
Summary of the invention
In conclusion developing a kind of all using natural polymers, copied by the pretreatment to tealeaves, compounding
It makes, producing with the good tealeaves fragrance wrapping paper of tealeaves form and fragrance, intensity height, printing adaptability is very to have reality
Meaning.Tealeaves fragrance wrapping paper be it is a kind of tealeaves is added in paper pulp, tealeaves is evenly spread in paper pulp, and is kept
Certain form and intensity, while guaranteeing the intensity and printing performance of page, there is the wrapping paper of special tea perfume made of manufacturing paper with pulp,
It can be used for the extra packages such as cosmetics, food.Tealeaves fragrance wrapping paper also retains tea other than the performance for meeting wrapping paper
The mode of appearance and its fragrance of leaf, and hygienic, sterile, pollution-free impurity etc., are the speciality paper with high added value.
In order to achieve the above object, the technical solution adopted by the present invention is that:
A kind of paper of tealeaves fragrance, is obtained by method comprising the following steps:
Nano-cellulose tealeaves dispersion liquid containing tealeaves blade is added in paper making pulp, is manufactured paper with pulp molding by wet process, it is dry
A kind of paper of tealeaves fragrance is obtained afterwards.
Further, the nano-cellulose tealeaves dispersion liquid containing tealeaves blade is by the component including following mass parts
It obtains:
10-40 parts of tealeaves
100 parts of water
0.1-2 parts of nano-cellulose
1-20 parts of acid fiber by polylactic.
Further, after using nano-cellulose to tealeaves pretreatment, match with total chlorine free bleaching Time of Fluff Slurry and bamboo pulp and copy, benefit
With three kinds of fibers (cotton pulp+softwood pulp+bamboo pulp) interpenetrating networks form, can while Paper bulk is high, improve tealeaves with
The binding force of fiber improves page characteristic.
Further, using bacteria cellulose, Cationic Konjac Glucomannan, nano-cellulose ternary system, improve at
Paper retention performance and uniform performance improve paper strength, and utilize the special of Cationic Konjac Glucomannan and nano-cellulose
Performance improves the antibiotic property of paper.
In conjunction with the above two o'clock, paper pulp used when wet process is manufactured paper with pulp, quality proportioning can be as follows:
30-80 parts of paper making pulp
20-70 parts of tealeaves dispersion liquid
1-10 parts of bacteria cellulose
