Abstract
The invention discloses a color biaxially-oriented polypropylene (BOPP) extinction film which comprises a layer A, a layer B and a layer C. The layer A and the layer C are surface layers, the layer B is a core layer, and the surface layer A comprises 97-99.5% of homopolymerization propene polymer (PP) or a random PP and 0.5-3% of anti-adhesion agent. The core layer B comprises 95-100% of homopolymerization PP and 0-3% of antistatic agent and 0-2% of slipping agent. The surface layer C comprises 95-99.5% of common extinction material and 0.5-5% of color extinction color master batch. The color BOPP extinction film is manufactured through steps of material mixing, melt extrusion, casting, vertical stretching, transverse stretching, dragging and side cutting, rolling, slitting, finished product forming and the like. The BOPP extinction film reduces solvent pollution caused by film printing and pre-coating, machine expenses and cost and is environment-friendly. The color of the film does not fade and is firm and pretty compared with printing.
Description
Technical field
The present invention relates to a kind of colored BOPP Extinctive thin film and production technology thereof, belong to coloured packaging field.
Background technology
The production of BOPP film 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.).The BOPP film is a kind of very important flexible packing material, the BOPP film is colourless, do not have smell, tasteless, nontoxic, and have high tensile, impact strength, rigidity, obdurability and the good transparency.
Because the BOPP Extinctive thin film is a kind of semitransparent thin film, kind is single, and in the plastic colourprinting industry being increases color through BOPP being carried out the colored printing of full version, not only take time and effort, and cost is high.
Summary of the invention
The present invention is directed to the problem in the background technology, researched and developed a kind of colored BOPP Extinctive thin film and production technology thereof, purpose is: increase the diversity of color, reduce full version printing, improve the packing quality.
Technical solution of the present invention: a kind of colored BOPP Extinctive thin film, comprise three layers of A, B, C, wherein A, C layer are the top layer, the B layer is a sandwich layer, it is characterized in that:
Top layer A is: 97～99.5% homopolymerization PP or random PP+0.5～3% antitack agent;
Sandwich layer B is: 95～100% homopolymerization PP+0～3% antistatic additive+0～2% slipping agent;
Top layer C is: the colored delustring color masterbatch of 95～99.5% normal dull material+0.5～5%.
