It meets environmental protection requirements and has no pollution ^ 2. Printing is safe and easy to manage. 3. Harmless to human health. The advantages of electroplated aluminum foil are: 1. Excellent gas and water barrier properties, suitable for food packaging with high freshness requirements. 2. With metallic luster and beautiful appearance, it can be used as gift wrapping paper after printing. Due to the biaxially-stretched polypropylene film, it is used in printing processing and electric keys. Its market volume is large, and water-based inks and electroplated weaves have the above-mentioned development trend of industrial and financial keys. Developed on the double-sided stretch polypropylene film of water-based inks. At present, the biaxial extension film has a weak surface tension and is difficult to print on oily inks. It is applied to food and X industry packaging. The disadvantages of printing are as follows: 1. The operation is dangerous and prone to fire. And explosion. 2. Environmental pollution. 3 _ Because of the use of toluene, methyl ethyl ketone, ethyl acetate, etc., often organic solvents are harmful to human health. ^ Also used in electroplating products, because the adhesion strength with aluminum foil is poor, so general electroplating manufacturers need to apply a layer of adhesive before plating 'The quality can meet the requirements. This product is usually used in food packaging and gift wrapping paper. In order to solve the above problems, the applicant's company has been manufacturing biaxially stretched polypropylene film for many years.

(Please read the precautions on the back before filling out this page.) An organic or inorganic anti-adhesive with an average particle size of less than 4 U is required. If the particle size is larger than 4, the surface is rough, which affects the printing and plating quality. Generally, the added amount is in the range of 0.05 to 0.4% by weight. ⑶ Antistatic agent: Including diethoxylated ammonium, ethyl acetate Ammonium oxide (Esterficated eth〇XyUted am, ne), glyceryl monostearate (Glycer〇1 M〇〇〇stearate).

Description of the invention () Manufactured by the biaxial extension method, and its manufacturing method system will gather The acrylic resin is heated and melted by an extruder, and then the T-type mold is extruded and cooled to form a polypropylene sheet. After preheating by a roller, the polypropylene sheet is extended longitudinally by 4 to 7 times at a speed ratio of two rounds. After the longitudinal extension, the polypropylene plate is clamped by a chain monk and preheated in the horizontal extension furnace, so that the loaded acrylic plate reaches the softening temperature and then is extended horizontally (the chain is stretched in a figure eight to extend). The horizontal extension ratio is 7 ~ 10 times, after the two-way extension, the polypropylene potassium plate has a thickness of I2 ~ Π0 u. In the biaxial stretching film production process, the flame treatment is selected on one surface. The so-called flame treatment refers to the biaxial extension during the process. The polypropylene film is cooled by a cooling meal, and A flame treatment device is used above the cooling wheel to generate liquefied natural gas by combustion: ~ 10mm flame, the surface of the film is irradiated with the flame to oxidize the surface of the film, thereby greatly increasing the surface energy of the film, and promoting the performance of water-based inks and aluminum foils. Long-term adhesion on the surface and excellent adhesion strength 'The biaxially stretched polypropylene film treated with this surface has the following characteristics: Extremely strong surface tension and surface tension with excellent long-term stability; excellent surface flatness; Suitable for water-based ink printing; In order for the biaxially stretched polypropylene film used in the present invention to be used for water-based ink printing and air-plating, it is necessary to perform silk processing on the biaxially stretched polypropylene. The present invention is performed multiple times according to the flame button condition and the quality of the combustion gas foot. According to the test results, it was found that the 6 1 'combustion gas is more suitable for the quality and treatment conditions of the combustion gas with the following parameters: using liquefied natural gas to burn a NG) methane content> 85%, and the flame-rolled tritium layer obtained by using methane combustion Contact with the surface of the polypropylene film to generate polar groups such as _CQ, _ pool 2. Among them, the higher the content of sintering, the more polar groups are called. This polar group has the printing adhesion to water-based inks and the chain of electroplating products. The better the adhesion of the foil, the content of methane in the combustion gas needs to be 45. 2. Polarization voltage: 0 · ΐ ~ 0.8KV, the optimum voltage is 0.2kv. Polarization voltage < (MKV is easy to slip film when finished product is coiled, poor coiling.

Cooling wheel temperature < 20 ° C 'The cooling wheel is prone to water droplets, which affects productivity and quality. Cooling wheel temperature > 50 ° C, the cooling of the film is not complete. 4_ Flame temperature: 700 ~ 900, it is the optimal temperature of 76CTC. Flame temperature < 700 ° C, the surface tension of the finished product is low, and the adhesion of water-based ink and aluminum foil Weak strength.

After mixing with a mixer, it enters two auxiliary extruder and is extruded in three layers at an extruder temperature of 2000 ~ 280 ° C. Τ-type die Out, the cooling wheel is used to cool and mold the acrylic sheets in the temperature range of I5 ~ 60 ° C. After the polypropylene sheets are molded, it enters the longitudinal stretching device and is preheated at a temperature setting of 13 ~ 155 " c. Then make 5 times longitudinal extension, and then temper and cool after extending. After cooling, enter the transverse extension device, preheat it at a temperature setting of 150 ~ 190 ° C, and then make 9 times lateral extension, and then extend it again. Tempering and cooling, after the lateral extension device is selected, one surface is selected for corma treatment, so that this surface is suitable for ordinary oily ink printing.

Description of the invention () The effect of the invention: 1. Biaxially stretched polypropylene film suitable for the production of the water-based ink printing of the present invention, and its biaxially stretched polypropylene The wetting tension of _ is better than that of conventional oil-based ink printing products. Because of the high surface tension of the film and the good adhesion to water-based inks, it is very suitable for water-based ink printing processing. 2. Custom oily ink printing products. _ The lower the wet tension is, the lower the surface tension is. It is used for water-based ink printing. After printing, water-based ink will be bad and easy to fall off, and some colors cannot be printed. Water-based ink printing. 3. The method for manufacturing a biaxially stretched polypropylene film suitable for heat-sealable electroplating of the present invention, the adhesion of the biaxially-stretched polypropene film electroplated aluminum foil and the film obtained is pasted with a siphon tape Then test by tearing by hand, the test result is very good adhesion, the aluminum box does not fall off. 4 · Because the film surface has high surface tension and does not contain additives that will ooze out, the adhesion of electroplated aluminum foil and film is excellent, and the bonding strength after bonding with other plastic materials is very suitable for electroplating products. And good quality.
