But, for the production of the smooth Biaxially oriented polypropylene fresh flower of height packing film, easily card, easily broken frequent generation on high-speed bag making machine, impact has the smooth BOPP fresh flower of the height packaging film of good coefficient of friction, the production of cannot raising speed on high-speed bag making machine, production efficiency is low, and production cost is high; For being used in, fresh flower packing is upper, and transparency and third dimension are desirable not enough.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of transparency high, third dimension is strong, and on high-speed bag making machine, production efficiency is high, and cost is low, does not block, constantly high smooth Biaxially oriented polypropylene fresh flower packing film and production technology.
The technical scheme that technical solution problem of the present invention adopts is: a kind of high smooth Biaxially oriented polypropylene fresh flower packing film, it is characterized in that on transparent sandwich layer all compound corona layers, below compound non-corona layer; Transparent sandwich layer is made up of 98% polypropylene and 2% HMW erucyl amide opening agent; Corona layer and non-corona layer are by the bead compatilizer composition of 98% polypropylene and 2%.
High smooth Biaxially oriented polypropylene fresh flower packing film and production technology, is characterized in that:
A. batching: the HMW erucyl amide opening agent of 98% polypropylene and 2% is put into C mixer, the bead compatilizer of 98% polypropylene and 2% is put into A mixer and B mixer stirs simultaneously; The material stirring is sent into respectively in B extruder, A extruder and B extruder and is extruded; The material of extruding is delivered to respectively in B filter, A filter and B filter and is filtered, and filters out impurity;
B. the material having filtered is sent in compounding machine compound simultaneously;
C. it is raw that the raw material after compound are sent in casting life casting, and carry out thickness measuring;
D. the casting life of thickness measuring is sent into longitudinal stretching machine, carry out longitudinal stretching; Carry out cross directional stretch by transverse drawing mill more afterwards and become film;
E. stretched film enters hauling machine and draws and secondary thickness measuring;
F. the film of two thickness measurings is through carrying out sided corona treatment to corona layer in electric spark processor;
G. film after treatment is bundled with winder rolling;
H. the film after rolling is put into the Ageing Treatment that Ageing Treatment device carries out 72 hours;
J. the film that Ageing Treatment is good is cut packing cutting in packing machine.
The invention has the beneficial effects as follows: this invention has improved transparency greatly, effectively improve the anti-animal migration of slipping agent, resistance to blocking and the smoothness of film, reduced coefficient of friction, make product can adapt to high-speed production requirement, production efficiency is high, and cost is low.
