Abstract
The invention discloses a high-fastness aluminum plating polypropylene (PP) film and a production process thereof in the field of film production. The film is formed by processes of PP homopolymerized, PP random copolymer and anti-sticking agent mixing and stirring, extrusion plastifying, compound forming, casting, longitudinal stretching, transverse stretching, corona, take-up and the like, so that the thickness of the film is decreased; according to the corona treatment surface, the PP copolymer which is taken as a major ingredient is combined with an anti-sticking agent in a specific ratio, so that relatively high corona treatment performance can be maintained, an aluminum-plating layer is difficult to drop, and the film can be applied to various fields such as food packaging, flower packaging and medicine packaging.
Description
Technical field
The present invention relates to a kind of film and production technology thereof, particularly a kind of its production technology of polypropylene film.
Background technology
The English meaning of bidirectional stretching polypropylene film is Biaxially Oriented Polypropylene, is called for short BOPP.Its production is that the melt of macromolecule polypropylene is at first processed sheet material or thick film through long and narrow head; Then in the stretching-machine of special use; Under the speed of certain temperature and setting; Simultaneously or the stretching on vertical both direction (vertically, laterally), carried out of substep, and the film of processing through suitable cooling or heat treatment or special processing (like corona, coating etc.).
Because the standard day by day of food products market, the specification requirement in packaging for foodstuff field at present is increasingly high, is increased sharply for quantity demand rapid growth, the quality requirement of the vacuum aluminum-coated BOPP film that is applied to packaging for foodstuff high-barrier purposes.Common BOPP aluminizer is done thinner and thinner from the consideration thickness of downstream client cost; But its most important performance---the bad problem of the fastness of aluminizing never is significantly improved, and in its application process, exists because the problem that aluminium coated comes off and causes barrier property to weaken and then shorten the food security shelf life greatly always; Detect according to the moistened surface tension force of GB14216-1993 standard existing film.The moistened surface tension force that obtains is generally about 40mN/m, and the moistened surface tension force of metallized film must not be lower than 42mN/m, and this just makes and BOPP film of the prior art surface aluminium coated poor adhesive force comes off easily.And the thickness of common BOPP film is thicker, generally between 18 ~ 25 microns, because the thicker production cost that must cause of its thickness uprises, if thickness is crossed thin problem such as can cause in drawing process, occurring easily breaking.
Summary of the invention
The purpose of this invention is to provide a kind of high fastness aluminize polypropylene film and production technology thereof, solve deficiency of the prior art, make the film surface fastness height of aluminizing; The aluminium coated difficult drop-off; Enhancement film barrier property, and the thickness of reduction film reduce production costs.
The objective of the invention is to realize like this: a kind of high fastness polypropylene film of aluminizing, comprise upper epidermis, sandwich layer and top layer down,

Step 4
Composite molding; The output of extruder one, extruder two, extruder three links to each other with die head through runner one, runner two, runner three respectively in said three units; In die head, the material of No. three extruders output is carried out composite layered, output composite sheet ° after die head adjusts corresponding articles thickness;
Step 5
The casting sheet; To cooperate the mode of water-cooled to carry out cooling and shaping through sharp cooling roll by the composite sheet of die head output;
Step 6
Longitudinal stretching; Cooled composite sheet is carried out longitudinal stretching on hot-rolling; Accomplish longitudinal stretching through preheating → stretching → typing; Said longitudinal stretching preheat temperature is 130 ° ~ 150 °, and said longitudinal stretching temperature is 130 ° ~ 140 °, and said longitudinal stretching setting temperature is 135 ° ~ 145 °;
Step 7
Cross directional stretch; Film behind the longitudinal stretching is carried out cross directional stretch in the mode of hot blast heating; Accomplish cross directional stretch through preheating → stretching → typing; Said cross directional stretch preheat temperature is 170 ° ~ 180 °, and said cross directional stretch temperature is 150 ° ~ 160 °, and said cross directional stretch setting temperature is 160 ° ~ 170 °;
Step 8
Corona; Through electrode bar film surface is carried out corona treatment;
Step 9
Rolling; Through winder form film is carried out rolling.
The interior temperature of die head is 240 ° in the said composite molding step.
The temperature of sharp cooling roll and water is 32 ° in the said casting sheet step.
Longitudinal stretching is than 400 ~ 500% in the said longitudinal stretching step.
Cross directional stretch is than 850 ~ 950% in the said cross directional stretch step.
