The accompanying drawing that will specifically combine in this utility model embodiment below, to the technical scheme in this utility model embodiment
It is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than complete
The embodiment in portion.Based on the embodiment in this utility model, those of ordinary skill in the art are not before making creative work
Put the every other embodiment obtained, all should belong to the scope of this utility model protection.
Refer to Fig. 1, for the structural representation of a kind of packaging board that this utility model embodiment provides, described packaging
Include with cardboard:
Intermediate layer 10, including at least one of which corrugating medium 11；
Being fitted in the extexine 20 of both sides, described intermediate layer 10, described extexine 20 includes being located close to described intermediate layer 10
The craft paper 21 of side, and it is positioned at outside, the kraft paper 22 with surface water-resistance, described kraft paper 22 blocks with described cattle
Paper 21 is bonded by binding agent.
Intermediate layer 10 uses corrugating medium to be formed, and can include one layer or multilamellar corrugating medium, can be according to the tool of product
Body requires to select the number of plies of corrugating medium.Corrugating medium has shock-absorbing capacity, has anti seismic efficiency, uses the core paper that the number of plies is more
The number of plies can improve anti seismic efficiency and the fastness of Packaging Box.
The kraft paper 22 being positioned at outside in extexine 20 has surface water-resistance, the most surface treated Corii Bovis seu Bubali
Paper, its paper surface water absorption (i.e. COBB value) is substantially reduced, and water is not easy to penetrate, and has preferable water resistance.
In the present embodiment, kraft paper 22 can use 40g/m2The kraft paper of gram quantity.After surface finish processes, its paper table
Face water absorption is substantially reduced, and general kraft paper absorbs 30 grams of moisture content in 60s, and this kraft paper that the present embodiment is after treatment
Absorbing about 17 grams moisture content in 60s, water-resistance improves.
In extexine 20, the craft paper 21 near intermediate layer can be fine dried noodles craft paper, coated craft paper, one side craft paper
Or two-sided craft paper, specifically can select according to product requirement.
Kraft paper 22 and the craft paper 21 in extexine 20 with surface water-resistance are bonded by binding agent, and binding agent is cattle
Form the bonding film 23 with water proofing property between mulberry paper 22 and craft paper 21, refer to Fig. 1.Kraft paper 22 passes through with craft paper 21
Binding agent close adhesion, can guarantee that the structural strength of extexine；Binding agent forms bonding film 23 between kraft paper and craft paper,
Having certain water proofing property, can improve the water resistance of cardboard further, when the kraft paper in outside damages, external water also difficulty penetrates
The bonding film formed, makes cardboard or carton still can keep good intensity.
In the present embodiment, optionally, binding agent can use polyethylene (PE), it is possible to is closely glued with craft paper by kraft paper
Close, and the PE layer formed has water proofing property.Binding agent can be specifically Low Density Polyethylene (LDPE), is also called the poly-second of high pressure
Alkene, its molding processibility is good.
Preferably, described binding agent can use the mixed adhesive that polyethylene is formed with reinforcing agent, at polyethylene adhesive
Middle addition reinforcing agent, it is possible to strengthen adhesion, makes bonding more firm, improves the structural strength of cardboard.
Accordingly, this utility model embodiment also provides for a kind of Packaging Box, uses cardboard as above, and cardboard includes
Intermediate layer and extexine, intermediate layer uses corrugating medium, and extexine of fitting in the both sides in intermediate layer, described extexine includes being positioned at
The craft paper of close side, intermediate layer, and it is positioned at the kraft paper in outside, kraft paper is bonded by binding agent with craft paper.It is positioned at
The kraft paper in outside has surface water-resistance, and water is not easy to be penetrated cardboard by cardboard outer, makes carton have preferable water proofing property
Energy.This carton can be used for ordinary packing carton it can also be used to the special carton of cold chain, applies in cold chain transportation, is condensate in paper
The globule outside case be not easy wet fall cardboard, there is preferable moistureproof and waterproof performance, cold chain transportation standard can be met.
Hereinafter the manufacture method of this utility model packaging board is described in detail.This utility model packaging board is first
Make formed extexine, then with corrugating medium laminating produce cardboard.
Wherein, refer to Fig. 2, for the flow process of manufacture method of a kind of cardboard extexine that this utility model embodiment provides
Figure, makes cardboard extexine, specifically includes following steps in the present embodiment:
S1: adhesive solids thing is added in compounding machine head, melt described adhesive solids thing by heating up, make bonding
Agent is liquefied；
The kraft paper with surface water-resistance is ready to craft paper, binding agent is added in compounding machine head, pass through
Screw rod high speed rotating heat also extrudes to zero-clearance to the first end of film, and after temperature reaches to a certain degree, adhesive solids thing is slow
Slowly start to melt, finally liquefy.
Preferably, described binding agent is the mixed adhesive that polyethylene is formed with reinforcing agent, adds in polyethylene adhesive
Enter reinforcing agent, it is possible to strengthen adhesion, make bonding more firm, improve the structural strength of cardboard.Concrete, low-density can be used to gather
Ethylene.
S2: flowed out by die orifice equably by the binding agent of liquefaction, contacts with kraft paper to be bonded or craft paper；
By the extruding of screw rod, produce certain pressure in making film head and make the binding agent of liquefaction equably from die orifice stream
Going out, the binding agent of liquefaction, after die orifice flows out, contacts with paper.
S3: by counter-pressure cylinder and cooling cylinder pressing, described kraft paper is fitted tightly with described craft paper；At bonding processes
In, chill roll makes the binding agent fast cooling of liquefaction, makes binding agent solidify, kraft paper is fitted tightly with craft paper together with.
After to be fit, by winder, the extexine product being combined is rolled into paper roll again standby.
The extexine that will produce above, produces cardboard with a watt spinulose tree fern core paper on corrugated paper board assembly line.Then can enter
One step, according to customer requirement size die cut paper sheet, is fabricated to carton.
The packaging board of this utility model offer and Packaging Box, the extexine of cardboard is by the cattle with surface water-resistance
Mulberry paper and craft paper are composited, and the kraft paper in outside makes water be not easy to penetrate, and have good waterproof and dampproof performance, apply
In cold chain transportation, the outside globule condensed of carton is not easy to penetrate cardboard, is difficult to the case that collapses, can keep the structural strength of carton；System
It is made the printable surface of carton, easily bonds, and environmental protection is easily reclaimed.
Above packaging board provided by the utility model and Packaging Box are described in detail.Used herein
Principle of the present utility model and embodiment are set forth by specific case, and the explanation of above example is only intended to help
Understand method of the present utility model and core concept thereof.It should be pointed out that, for those skilled in the art,
On the premise of this utility model principle, it is also possible to this utility model is carried out some improvement and modification, these improve and
Modification also falls in this utility model scope of the claims.
