Problems solved by technology

[0015] However, in the conventional modifiers disclosed in Patent Documents 1 to 3, it takes time for the polyolefin-based resin to exhibit the anti-fogging effect, and when the additive amount is increased in order to improve these, there is a risk of damage to the heat-sealable tape. problems with adverse effects

no. 1 Embodiment approach

[0050] First, a description will be given of a first embodiment of a modifier for a polyolefin resin (hereinafter referred to as a modifier) ​​for concretely realizing the present invention.

[0051] Examples of the ester compound used in the modifier of the present embodiment include those selected from the group of partial esters of dihydric alcohols having 2 to 4 carbon atoms and aliphatic monocarboxylic acids having 8 to 22 carbon atoms. at least one. These may be used alone or in combination of two or more.

[0052] Among the partial esters of dihydric alcohols with 2 to 4 carbon atoms and aliphatic monocarboxylic acids with 8 to 22 carbon atoms, specific examples of dihydric alcohols with 2 to 4 carbon atoms include ethylene glycol, Alcohol, Propylene Glycol, Butylene Glycol, etc. In addition, specific examples of aliphatic monocarboxylic acids having 8 to 22 carbon atoms include caprylic acid, nonanoic acid, capric acid, undecylic acid, undecylenic acid, lauric acid, ...

no. 2 Embodiment approach

[0082]Next, a second embodiment of the polyolefin-based resin composition (hereinafter referred to as the resin composition) for realizing the present invention will be described. The resin composition of the present embodiment contains the modifier of the first embodiment described above in a polyolefin resin. The resin composition of this embodiment contains the modifier of 1st Embodiment in the ratio of 0.45-5.0 mass % in a resin composition. When the total content ratio of the polyolefin resin and the modifier of the first embodiment is 100 parts by mass (100 mass %), it is preferable to contain the polyolefin resin in a ratio of 99.55 to 95.0 parts by mass (mass %), and to The modifying agent of the first embodiment is contained in a ratio of 0.45 to 5.0 parts by mass (mass %). By limiting to this range, especially antifogging property and antistatic property can be further improved. In addition, film forming stability when the resin composition is molded into a film ca...

no. 3 Embodiment approach

[0087] Next, 3rd Embodiment which concretely demonstrates the modified polyolefin resin film (henceforth a film) of this invention is demonstrated. The film of the present embodiment is obtained by molding using the resin composition of the second embodiment. The film of the present embodiment contains the modifying agent of the first embodiment in a ratio of 0.45 to 5.0% by mass in the film. By limiting to this range, especially antifogging property and antistatic property can be further improved. In addition, film formation stability can be improved.

[0088] A known method can be used for the molding method of the film of this embodiment, and examples of the molding method include inflation molding such as air-cooled inflation molding, air-cooled two-stage inflation molding, and water-cooled inflation molding, and use as a T-die. T-die molding of straight manifold type, coat hanger type, and a combination of them. The film of the present embodiment can be formed by any o...

Abstract

Provided is, for example, a modifier that is for a polyolefin resin and that can provide excellent anti-fogging properties to the polyolefin resin without adversely affecting the inherent heat-sealing properties of the polyolefin resin. The modifier for a polyolefin resin according to the present invention is characterized by containing an ester compound and a nonionic surfactant, wherein the mass ratio (ester compound) / (nonionic surfactant) of the contained amount of the ester compound with respect to the contained amount of the nonionic surfactant is 10 / 90-30 / 70. The ester compound is at least one selected from the group consisting of partial esters of divalent alcohols having 2-4 carbon atoms with aliphatic mono-carboxylic acids having 8-22 carbon atoms. The nonionic surfactant is at least one selected from the group consisting of partial esters of tri- to hexavalent alcohols with aliphatic mono-carboxylic acids having 8-22 carbon atoms, specific ester compounds, and specific ether compounds.

Description

technical field [0001] The present invention relates to a modifier for polyolefin resins, a polyolefin resin composition containing the modifier, a modified polyolefin resin film containing the modifier, and a resin layer containing the modifier on at least one surface. Laminated films of modifiers. Background technique [0002] Films obtained by molding polyolefin-based resin compositions are widely used as representative packaging materials. However, polyolefin-based resin itself has a hydrophobic property, so there is a problem that electrostatic charging, fogging, and the like occur. [0003] In order to solve this problem, for example, modifiers for polyolefin resins disclosed in Patent Documents 1 to 4 are known. [0004] Patent Document 1 discloses a modifier comprising partial esters of polyhydric alcohols and aliphatic monocarboxylic acids, nonionic surfactants such as alkyldiethanolamines, alkali metal salts of alkylsulfonic acids, alkylaryl Alkali metal sulfoni...
