Problems solved by technology

[0005] However, although polyester resin is excellent in non-absorbing performance, it has the disadvantage of being poor in the performance of inhibiting the permeation of moisture contained in the content, that is, the moisture barrier property.

Embodiment 1～4

[0145] Melt-knead polyester resin (A), cyclic olefin copolymer resin (B) and ethylene-based ionomer resin (C) in the proportions shown in Table 3 to prepare a resin composition for packaging body molding. Material.

[0146] This molding material was molded into a stretch-blow container (bottle), and the moisture barrier property (moisture loss rate) and the adsorption property of DL-α-tocopheryl acetate (vitamin E acetate), which is a fat-soluble vitamin, were measured. (recovery rate), and the adsorption (recovery rate) of 3-methyl-4-isopropylphenol which is an alkylphenol-based compound. In addition, a drop test of the molded stretch-blow container (bottle) was performed. The results are shown in Table 3.

Embodiment 5

[0161] Melt-knead polyester resin (A), cyclic olefin copolymer resin (B) and vinyl ionomer resin (C) in the proportions shown in Example 1 of Table 3 to prepare a resin composition consisting of Packaging molding materials.

[0162] With respect to this molding material, stretch blow molding containers (bottles) were molded in the same manner as in Examples 1 to 4, and the adsorption (recovery rate) of benzalkonium chloride as a quaternary ammonium compound and the adsorption (recovery rate) of benzalkonium chloride as a terpenoid compound were measured. Adsorptivity (recovery rate) of l-menthol, hinokitiol and oryzanol, and adsorption property (recovery rate) of stearyl glycyrrhetinate. The results are shown in Table 4.

[0163] As can be seen from Table 4, the molding material of the present invention can effectively suppress the adsorption of the above-mentioned components.

Embodiment 6

[0167] Melt-knead polyester resin (A), cyclic olefin copolymer resin (B) and vinyl ionomer resin (C) in the proportions shown in Example 1 of Table 3 to prepare a resin composition consisting of Packaging molding materials.

[0168]With respect to this molding material, a stretch-blow container (bottle) was molded in the same manner as in Examples 1 to 4, and a sensory evaluation was performed on the adsorption of aroma components in lemon oil. The results are shown in Table 5.

[0169] From the evaluation results, it can be seen that there is no attenuation of aroma, and the adsorption of aroma components in lemon oil can be effectively suppressed.

Abstract

Disclosed is a material for forming a packaging body, which constitutes at least a part of a packaging body coming into contact with an aqueous composition containing a lipophilic substance and comprises a resin composition containing (A) a polyester resin, (B) a cyclic olefin copolymer resin, and (C) an ethylene ionomer resin, wherein the content of the component (A) is from 60 to 85% by mass, the content of the component (B) is 10% by mass or more, and the total content of the component (B) and the component (C) is from 15 to 40% by mass. Also disclosed are: a packaging body, at least a part of which comprises the material for forming a packaging body; a product obtained by filling the packaging body with an aqueous composition containing a lipophilic substance; and a method for preventing the adsorption of a lipophilic substance contained in an aqueous composition using the material for forming a packaging body.

Description

technical field [0001] The present invention relates to a material for forming a package, a package formed using the material for forming a package, a product formed by filling the package with an aqueous composition, and a method for preventing the absorption of fat-soluble substances contained in the aqueous composition. method. Background technique [0002] It is well known that fat-soluble vitamins such as vitamin E or its derivatives are adsorbed by resins. Conventionally, non-absorptive materials such as glass have been used instead of resins for containers and packaging materials containing fat-soluble vitamins. [0003] In addition, the above-mentioned adsorption phenomenon does not necessarily occur for all resins, so after confirming the presence or absence of adsorption, resins with no or little adsorption can be used as container packaging materials. However, when resin is used as a container packaging material, it is necessary to check whether it is adsorbable ...
