Embodiment

[0084] Hereinafter, the present invention will be described using Examples and Comparative Examples. In addition, each measurement value in the detailed description of invention, an Example, and a comparative example was measured by the following method.

[0085] (1) Ethylene unit content and 1-butene unit content of polypropylene (unit: weight %)

[0086] IR spectrum measurement was carried out, and the ethylene unit content was determined according to the method for (i) random copolymer described on page 616 of Polymer Handbook (published by Kinokuniya Shoten in 1995). IR spectrum measurement was performed, and the 1-butene unit content was determined according to the method described on page 619 of Polymer Handbook (published by Kinokuniya Shoten in 1995).

[0087] (2) Melting temperature (unit: ℃)

[0088] Using a differential scanning calorimeter manufactured by Perkin Elmer, about 10 mg of the test piece was melted at 220°C in a nitrogen atmosphere, and then rapidly co...

[0106] Production of polypropylene (A-1)

[0107] Using the catalyst described in Example 1 of JP-A-2008-208362, propylene was polymerized to obtain a propylene homopolymer (melting temperature 164° C., MFR 9 g / 10 minutes, shear viscosity 278 Pa·s. PP(A-1)) powder. With respect to 100 parts by weight of PP (A-1), 0.002 parts by weight of calcium hydroxide (manufactured by Suzuki Industry Co., Ltd.) and 0.15 parts by weight of Irganox 1010 (manufactured by Ciba Specialty Chemicals) were added, and melt-kneaded to obtain PP (A-1). 1) Particles.

[0109] Production of polypropylene (A-2)

[0110] Using the catalyst described in Example 1 of JP-A-2008-208362, propylene, ethylene, and 1-butene were copolymerized to obtain a propylene-based copolymer (propylene-ethylene-1-butene terpolymer, Ethylene content 0.9% by weight, 1-butene content 3.4% by weight, melting temperature 148°C, MFR 7g / 10min, shear viscosity 350Pa·sec. Hereinafter referred to as PP (A-2)) powder. With respect to 100 parts by weight of PP (A-2), 0.007 parts by weight of calcium hydroxide (manufactured by Suzuki Industries, Ltd.), 0.09 parts by weight of Irganox 1010 (manufactured by Ciba Specialty Chemicals), and 0.05 parts by weight of SUMILIZER GP (manufactured by Sumitomo Chemical Co., Ltd.) were added parts, and melt-kneaded to obtain PP (A-2) pellets.

A ) of 2 to 12 g / 10 minutes, 60 to 90 parts by weight of component (A) as polypropylene; and the melt flow rate (MFR) measured at 190°C and a load of 21.18N B ) of 15 to 100 g / 10 minutes, 10 to 40 parts by weight of component (B) as high-pressure low-density polyethylene (wherein the total amount of component (A) and component (B) in the above composition is set to 100 parts by weight.).

Description

technical field [0001] The present invention relates to a polyolefin-based resin composition for a vapor-deposition film that exhibits excellent vapor-deposition strength before and after heat-sealing when it is formed into a film and heat-sealed after vapor-depositing a metal or a metal oxide, including the vapor-deposition film. A polyolefin film for vapor deposition using a polyolefin-based resin composition, and a vapor deposition film having a layer containing the polyolefin film for vapor deposition and a layer containing a metal or metal oxide. [0002] Here, the vapor-deposited film is a laminate obtained by vapor-depositing a metal or a metal oxide on a film, and having a film and a layer containing a metal or a metal oxide. In addition, the polyolefin film for vapor deposition is a polyolefin film used as a vapor deposition film by vapor-depositing a metal or a metal oxide. In addition, the polyolefin resin composition for vapor deposition is a polyolefin resin comp...
