Description
Technical field
The present invention relates to the film technique of chemical technology field, more particularly to a kind of paper cup material.
Background technology
Paper cup material is generally made up of polyethylene (PE) film of body paper and film on body paper surface.Paper cup material has quality
Lightly, antiseep, the advantages that printing is attractive in appearance, easy to process, the dixie cup prepared using paper cup material, available for holding tea, fruit
The multiple beverages such as juice, coffee, milk, soya-bean milk, congee, dixie cup because of its health characteristic such as light, be widely used in daily life and
In office.
In polyethylene film into the processing technology on body paper surface, reasonably controlling the degree of cohering of body paper and polyethylene film is
Committed step, if cohering between body paper and polyethylene film is spent small, polyethylene film delamination can be caused, causes finished product dixie cup to go out
The phenomenon of existing seepage；If cohering between body paper and polyethylene film is spent greatly, in the recovery processing technique after dixie cup is discarded,
Polyethylene film is difficult to be separated with paper substrate, causes the string in body paper to hardly result in efficient recycling, causes a large amount of treasured
The waste of your plant resources.Therefore, reasonably the degree of cohering between control body paper and polyethylene film has in dixie cup production process
There is important realistic meaning.
The content of the invention
It is an object of the invention to provide the film technique in a kind of dixie cup production process so that the paper cup material of preparation has
Appropriate degree of cohering, it both can guarantee that PE film not delaminations and can ensured that body paper efficiently recycles.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of film technique of paper cup material, comprises the steps：

Film, the body paper printing surface of high speed conveying is then obtained into film with polyethylene film via the compound disk roller progress to run at high speed is compound
Paper, the extruder barrel section temperature is 150-350 DEG C, die head section temperature is 310-350 DEG C, and the pressure of the compound disk roller is
100-130kg/m2；
(4) cool down
Leaching membrane paper is cooled down using circulating water cooling device, the temperature of cooling water is 10-15 DEG C；
(5) wind
Leaching membrane paper after cooling is delivered to rolling-up mechanism and forms leaching membrane paper paper web, leaching membrane paper is controlled in wrapup procedure
Winding tension is 15-40kg/m2；
(6) paper web storage conveying
Leaching membrane paper paper web is packed, and storage region is transferred to by exclusive trail car, is received by subsequent processing.
Preferably, the body paper first carries out fluorescent material and content of beary metal detection before unreeling structure is loaded.
Preferably, the body paper first carries out degerming mould proof processing before unreeling structure is loaded using ultraviolet or alcohol.
Preferably, the polyethylene particle first carries out impurity content detection before use.
Preferably, it is described unreel or wrapup procedure in, unwinding tension or winding tension are carried out according to the thickness of paper
Adjustment.
Preferably, the step (1) to (6) is in 6-7kg/m2Air pressure under implement.
Preferably, the temperature of the machine barrel first paragraph of the extruder be 150-180 DEG C, the temperature of second segment be 210-240
DEG C, the 3rd section of temperature be 260-290 DEG C, the 4th section of temperature be 310-350 DEG C, die head section temperature be 310-350 DEG C.
Relative to prior art, the beneficial effects of the invention are as follows：
In film technique of the present invention, unreeled and winding tension, melting temperature, corona current, compound pressure by strictly controlling
The parameters such as the temperature of power, the thickness of PE films and cooling water so that have between the body paper and PE films of the PE-coated paper material produced
There is appropriate degree of cohering, the dixie cup finished product prepared using PE-coated paper material of the present invention had both been not in delamination, the phenomenon of seepage,
Be advantageous to the high efficiente callback of string in discarded dixie cup again.
The present invention simultaneously also prevent well and avoid in corona process due to electric current is excessive and caused by paper perforate
Body paper smooth surface caused by phenomenon and corona are bad, the phenomenon so as to influence with PE degree of cohering.
