Abstract
The invention discloses a kind of with cellulose modified vegetables and fruits Corrugated fiberboard, and manufacturing method is that waveform is made in corrugating media by Corrugating Machine, then respectively bonds one layer of modified kraft in corrugating media upper and lower surface.
Description
Technical field
The present invention relates to corrugated paper technical field more particularly to a kind of corrugated paper is packed for cellulose modified vegetables and fruits
Plate.
Background technique
Paper and cardboard as conventional packaging material, be developed so far be still modern packaging material one of mainstay.In
State, paper packing material accounts for 40% or so of packaging material total amount, and in terms of development trend, the dosage of paper wrapper can be increasing.According to
Chinese packaging net report, although Chinese paper product usage amount growth is swift and violent, existing product structure and demand in the market
Structure is incompatible therewith, is mainly shown as that quality scale is low, breed structure is unreasonable.Currently, Chinese paper and board product product
Kind is less, not as good as the half that developed country can produce paper kind.Meanwhile product technology content is lower, second-rate, Packaging Box passes
The packaging function of system cannot fully meet consumer demand.
Although corrugated case is with light-weight, cushion performance is good, modeling structure plasticity is strong, the advantages such as nuisanceless are widely applied
In vegetable and fruit packaging, but the fresh and live agricultural product of high moisture content this for water fruits and vegetables, there are still deficiencies for common corrugated case
Place.Fruit and vegetable food moisture content is high, packs its moisture with corrugated case and is easy to evaporate, scatters and disappears, causes fruits and vegetables to wilt, weightless, product
Matter decline.During transportation, the fresh of fruits and vegetables how is kept, is always the technical problem for failing to be satisfactorily resolved.
In the prior art, it is that fruit insures, but is using due to insuring liquid that fruit surface is smeared insurance liquid by most of fruit quotient
When be difficult to clean, can do harm to huamn body, thus should not large area move back extensively;It is just needed on packing case for this problem
Certain modification is carried out, in particular for certain modification is carried out in production process to corrugated paper body paper, to prepare safe nothing
Poison is suitble to the corrugated case of preserving fruit and vegetable utilizing.
Summary of the invention
The object of the invention is to remedy the disadvantages of known techniques, provides and a kind of is packed for cellulose modified vegetables and fruits
Corrugated board.
The present invention is achieved by the following technical solutions:
A kind of cellulose modified vegetables and fruits Corrugated fiberboard, manufacturing method are by Corrugating Machine by corrugating media system
Then waviness respectively bonds one layer of modified kraft in corrugating media upper and lower surface.
A kind of manufacturing method with Modified Cellulose Modified vegetables and fruits Corrugated fiberboard, the modified kraft
Preparation method is:It is formed a film using spray liquid in brown paper surface spray, forms the modified kraft with a thickness of 40-50 μm, it is natural
It is put into vacuum oven after air-drying with 50-60 DEG C of drying.
The preparation method of the preparation method of modified kraft, the spray liquid is as follows:Cellulose acetate is dried in vacuo
It goes within 90-120 minutes after moisture removal for use;Dehydrated alcohol and acetic acid are mixed to form solution in equal volume, are heated to 50-60 DEG C, so
After be added cellulose acetate, control solid-to-liquid ratio is 1:(2.5-3), with 300-400 revs/min of speed stirring until cellulose acetate
It is completely dissolved, reaction solution is centrifuged 10-15 minutes with 8000-8500 revs/min of speed then, supernatant is taken, obtains spray liquid.
A kind of manufacturing method with Modified Cellulose Modified vegetables and fruits Corrugated fiberboard, the tool of the corrugating media
Manufacturing method is as follows:
(1)It is small that immersion 3-4 in suitable deionized water will be added after the mass mixings such as needle-leaved wood fibre and broad-leaved wood fiber
When, it is then placed in hydrabeating machine lever lever arm load 50-55N after discongesting 30-40 minutes and is beaten, controlled certain
Slurry concentration and beating degree obtain mixed slurry;
(2)A certain amount of cellulose acetate, cationic starch, alkyl ketene dimer are added to above-mentioned mixed slurry
In, copy paper is carried out after mixing evenly, copies quantitative 30-40g/m with standard sheet former2Page, squeezing drying, be then placed in
In vacuum oven with 40-50 DEG C of processing 6-8 hours to obtain the final product.
The specific manufacturing method of corrugating media, step(1)Described in the certain slurry concentration and beating degree of control be
Refer to that control slurry concentration is 1.8-2%, beating degree is 70-80 ° of SR.
The specific manufacturing method of corrugating media, step(2)Described in the additive amount of cellulose acetate be mixed slurry
2.5-3%, the additive amount of cationic starch are the 1-1.5% of mixed slurry, and the additive amount of alkyl ketene dimer is mixed slurry
2-2.5%.
It is an advantage of the invention that:The present invention is modified by the preparation process of corrugated board, first in corrugating media
Suitable cellulose acetate is added in preparation, due to light, degradable advantage, so that manufactured corrugated paper has good bullet
Property, it is cooperateed with cationic starch, alkyl ketene dimer, so that corrugating media dredging with good sizability and centainly
It is aqueous;Again by being modified in the brown paper of corrugating media upper and lower surface, obtain cellulose acetate table and be sprayed film formation surface changing
Property corrugated board, there is certain hydrophobicity, while the breathable and moisture that will not scatter and disappear has common corrugated board to compare,
Manufacture be more suitable into the corrugated case of fruits and vegetables, can be avoided fruits and vegetables and cause moisture loss during transportation, breathes freely simultaneously,
Fruits and vegetables cell eupnea can be kept, the freshness of fruits and vegetables is maintained, while there is good mechanical property, improves cracky
Disadvantage.
For the present invention by reasonable process modification, it is simple to obtain manufacturing process, low in cost, to human body and environmentally friendly
Corrugated board can be made fruits and vegetables and transport dedicated corrugated case, to the of good preservation effect of fruits and vegetables, have very strong marketing
Property.
