The present invention is a propylene polymer containing a lubricant and an antistatic agent, which is obtained by adding a specific inorganic filler and molding the polymer, thereby achieving slipperiness, anti-blocking properties, and antistatic properties without impairing transparency. This invention relates to an improved propylene polymer film. In general, propylene polymer films have excellent transparency, but are inferior to opaque films in slipperiness, blocking resistance, and antistatic properties. To compensate for these shortcomings, antiblocking agents, lubricants, and antistatic agents are added. It is essential to do so. Among these film modifiers, the use of various inorganic fillers as anti-blocking agents has long been known, and as film materials, lubricants and antistatic agents are generally used in combination with inorganic fillers. . However, the blocking resistance is insufficient,
In order to further improve this, when the amount of these inorganic fillers added is increased, the cause is not necessarily clear, but it seems that the lubricant or antistatic agent used in combination is adsorbed by the inorganic filler, resulting in slipping. , the effect of improving antistatic properties is reduced. Therefore, it becomes necessary to add a large amount of lubricant or antistatic agent,
Due to the large fluctuation in addition accuracy, quality stability of slipperiness and antistatic properties may be compromised.
The problem arises that it leads to an increase in prices. Therefore, as a result of intensive studies to improve this drawback, the inventors of the present invention found that by using an inorganic filler with a BET specific surface area of 200 m 2 /g or less and an apparent specific gravity of 0.2 or more as an anti-blocking agent, the lubricant and The present invention was made based on the discovery that a film with excellent slipperiness and antistatic properties can be obtained without significantly increasing the amount of antistatic agent added. That is, the present invention is a propylene polymer film characterized by comprising each of the following components (a) to (c) and produced by a conventional method. (a) Propylene polymer 100 parts by weight (b) Lubricant, antistatic agent, or both 0.01~
5 parts by weight (c) 0.05 to 5 parts by weight of an inorganic filler with a BET specific surface area of 200 m 2 /g or less and an apparent specific gravity of 0.2 or more The propylene polymer film of the present invention has excellent slip properties without impairing transparency. It has improved anti-blocking and anti-static properties, and can be used in conventional film fields such as packaging, agriculture, containers, construction materials, rain gear, etc., regardless of whether it is unstretched, stretched, shrunk or laminated. Available for use. It can also be used in sheet fields such as trays and plates. Propylene polymer used in the present invention (component (a))
In addition to crystalline homopolymers of propylene (polypropylene), these include crystalline multi-component copolymers of two or more elements in which propylene is copolymerized with 30% by weight or less of other olefins such as ethylene, butene, pentene, hexene, etc. Polypropylene and copolymers of propylene and other olefins may be added with unsaturations such as styrene, vinyl acetate, maleic anhydride, (meth)acrylic acid, or their esters in amounts that do not significantly alter the film properties of these polymers. It also includes copolymers in which monomers are grafted together or mixtures of these polymers. Furthermore, as the lubricant and antistatic agent (component (b)) used in the present invention, all those commonly used in polyolefin films can be used. That is, lubricants include (a) hydrocarbon-based lubricants such as fluid, natural or synthetic paraffin, microwax, polyethylene wax, and chlorinated polyethylene wax; (b) fatty acid-based lubricants such as stearic acid and lauric acid; (c) Fatty acid monoamides or bisamides such as stearic acid amide, palmitic acid amide, oleic acid amide, ethyl acid amide, methylene bis stearamide, ethylene bis stearamide, (di)butyl stearate, hydrogenated castor oil, ester-based products such as ethylene glycol monostearate,
(e) Alcohol-based soaps such as cetyl alcohol and stearyl alcohol, (f) Metal soaps such as lead stearate and calcium stearate, and (g) mixtures thereof, but especially fatty acid monoamide-based or bisamide-based soaps. is preferred. On the other hand, antistatic agents include (a) primary amine salts, tertiary amines, quaternary ammonium compounds,
Cationic products such as pyridine derivatives, (b) sulfated oils, soaps, sulfated ester oils, sulfated amide oils, olefin sulfate ester salts, fatty alcohol sulfate ester salts, alkyl sulfate ester salts,
Fatty acid ethyl sulfonate, alkylnaphthalene sulfonate, alkylbenzene sulfonate,

Non-ionic materials such as polyethylene glycol,
(d) Amphoteric ones such as carboxylic acid derivatives and imidazoline derivatives can generally be used, but nonionic ones, especially polyoxyethylene alkylamine, polyoxyethylene alkylamide, their fatty acid esters, and fatty acid esters of glycerin are particularly useful. etc. are preferred. In addition, the inorganic filler (component (c)) used in the present invention
has a BET specific surface area of 200 m 2 /g or less and an apparent specific gravity of 0.2 or more, and its types include calcium carbonate, magnesium carbonate, kaolin, pyrofluorite, talc, montmorillonite, silica, mica, chlorite, and seri. site, barium sulfate,
Examples include calcium sulfate and zeolite. The BET specific surface area of such an inorganic filler is 200 m 2 /g
In the above cases, as shown in the comparative examples later, the slipperiness and antistatic properties are significantly deteriorated regardless of the apparent specific gravity, and the BET specific surface area is 200 m 2 /g.
Even if the apparent specific gravity is below 0.2, deterioration of slipperiness and antistatic properties is still observed. The BET specific surface area mentioned here is measured by a method in which nitrogen gas is adsorbed onto the sample surface under liquid nitrogen temperature (described in "Powder Measurement" co-authored by Oher and Dara Abaal, translated on page 123 of the industrial book). represent something. Moreover, the apparent specific gravity was measured in accordance with JISK-6220. The blending ratio of each component (a) to (c) above is (a) component
The amount of component (b) is 0.01 to 5 parts by weight, preferably 0.04 to 2 parts by weight, and the component (c) is 0.05 to 5 parts by weight, preferably 0.1 to 3 parts by weight, per 100 parts by weight. The amount of component (b) to be blended is determined depending on the required level of slipperiness or antistatic properties. Regarding component (c), if it exceeds 5 parts by weight, the deterioration of transparency will be noticeable, and if it is less than 0.05 parts by weight, no blocking improvement effect will be obtained.
Moreover, the slipperiness also deteriorates. In addition to these components (a) to (c), various auxiliaries such as antioxidants, neutralizers, antifoam agents, flame retardants, dispersants, and ultraviolet absorbers may be added as appropriate to improve the strength of the film of the present invention. Low, medium, and high density polyethylene, ethylene-vinyl acetate copolymer, Ethylene-
Other thermoplastic resins such as (meth)acrylic acid (ester) copolymer, maleic anhydride grafted polyethylene, acrylic acid grafted polyethylene, and nylon can also be added and blended. The present invention is a film made of the above-mentioned components and produced by a conventional method. Generally, the inflation method and the T-die method are known as methods for producing films, and the film of the present invention may be produced by either method. Next, the present invention will be specifically illustrated with examples. However, in the example below, the film transparency is ASTM
D-1003, and the film slipperiness is ASTM D.
-1894, each was measured in accordance with the static friction coefficient measurement method. Further, the antistatic property of the film was measured by the following method. That is, sample dimensions: 40 mm x 40 mm (effective area 32 mm x 32 mm) Measuring equipment: Static Honest meter TYPE S-4104 manufactured by Shishido Shokai Co., Ltd. Measuring method: Measure the sample in a room at 23 ± 2°C and 50 ± 5% RH. was fixed on a rotating disk rotating at 1550 rpm, and a voltage of 10 KV was applied to the sample for 2 minutes while rotating the rotating disk. After the voltage was turned off, the decay curve was recorded on a recorder-type mV meter for 3 minutes while the rotary disk was kept rotating, and the half-life was read, and the antistatic property of the film was determined based on the half-life. Further, the blocking property of a film is expressed by the maximum shearing load required to peel off two films that have been brought into close contact with each other under load.
Specifically, two films are stacked so that the contact area is 10cm2 , placed between two glass plates, and 50g/
Conditioning is performed by applying a load of cm 2 . Thereafter, the film is peeled off at a tensile speed of 500 mm/min using a Schottper type tensile tester, and the maximum load is measured. Experimental Example 1 At a melt flow rate of 7.0 g/10 minutes, 100 parts by weight of propylene-ethylene random copolymer powder with an ethylene content of 5.0% by weight, 0.10 parts by weight of 2,6-di-t-butyl-p-cresol, and a lubricant. 0.06 parts by weight of erucic acid amide and 0.4 parts by weight of various inorganic fillers were added and mixed, and granulated at 240°C. In addition, among the above components, 0.2 parts by weight of Electro Slipper TS3, which is a blend of nonionic surfactants manufactured by Kao Soap Co., Ltd., was added as an antistatic agent in place of the lubricant erucic acid amide. In addition, granulation was performed in the same manner as above, except that the amount of each inorganic filler added was reduced from 0.4 parts by weight to 0.25 parts by weight. Each of these two types of granules has a screw diameter of
Using an extruder with 35 mm and L/D of 28, the die temperature

A film with a thickness of 30μ was produced by extrusion onto the surface of a casting drum (hard chrome plating) in which cooling water at 25°C was circulated.
In addition, each component of the two types of granules described above, excluding only the inorganic filler, was granulated to produce a film with a thickness of 30 μm at a die temperature of 230°C. Regarding these films, those containing a lubricant were measured for transparency and slipperiness, and those containing an antistatic agent were measured for transparency and antistatic properties. The results are shown in Table 1.
