Part, oriental wormwood 4-20 parts, rough gentian 5-21 parts, radix scutellariae 4-26 parts, polygala 4-23 parts are added to big fire heating in 5 times of deionized waters and boiled
10-30min, after switch to small fire and endure 12-24h slowly until solution boils dense fluids, after be cooled to room temperature thick liquid be made；
(2) by ultra-low density polyethylene 5-12 parts, carboxymethyl chitosan 1-15 parts, tea oil 2-13 parts, sodium alginate 5-11 parts,
Tartaric acid 2-10 parts, which are added to, to be heated to 50-100 DEG C in 5 times of deionized waters and is melted, and is stored at room temperature cooling 30-60min, after
Macromolecule glue 5-50 parts, dimethyl maleate 2-10 parts are added, rear 200-1000rpm/min stirrings, what is be uniformly dissolved is super
Low density polyethylene (LDPE) solution；
(3) added under stirring into the ultra-low density polyethylene solution of preparation paper pulp 1-40 parts, nano aluminium oxide rubber powder 2-10 parts,
Pearl powder 5-20 parts, polymethyl methacrylate 2-10 parts, polyvinyl alcohol 2-10 parts, mucopolysaccharide 6-30 parts, interleaving agent 1-8 parts rise
Temperature adds acid or alkaloid substance adjusts pH value to 6-8, then 100-500rpm/min 30-60 to 30-50 DEG C of stirring 15-60min
DEG C insulated and stirred 20-60min, it is rear to stand room temperature cooling, obtain mixed solution；
(4) step 3 mixed solution, ultra-low density polyethylene solution, step 1 concentrated solution and residue is added into high-speed mixer to go
Ionized water, 1000-3000rpm/min stir, and being sufficiently stirred makes it well mixed, obtains pulp liquor；
(5) by pulp liquor 2000-5000rpm/min homogeneous scattered 10-20min again, acid or alkaloid substance regulation pH value are added
It is rear to stand room temperature cooling to 6-8, then 1000-5000rpm/min 20-40 DEG C insulated and stirred 20-40min, after will mix paper pulp
Liquid adds banbury, is transferred to after banbury 10-30min in extruder, melting extrusion pulp liquor, is most passed through afterwards at 150-200 DEG C
Room temperature is naturally cooled into wrapping paper material.
(6) wrapping paper material is put into bag and turns paper producing apparatus one production line, produced wrapping paper, pass through brush after wrapping paper production
Film machine is in top layer brush layer of polyethylene film.
