た。特に内容物の入った容器のまま電子レンジ等で加熱
調理する際には、一層不快臭が助長されるので食品容器
として満足されうるちのではなかった。Polyolefin resin compositions made by adding talc or calcium carbonate to polyolefins are used as food packaging containers because they are heat resistant or easily incinerated. however,
Polyolefin resins, talc, and calcium carbonate themselves do not have unpleasant odors, but polyolefin resin compositions in which talc and calcium carbonate are mixed with polyolefin resins have unpleasant odors, which is problematic when used as food packaging containers. In particular, when the container containing the contents is heated in a microwave oven or the like, the unpleasant odor is further promoted, so that the container is not satisfactory as a food container.
本発明の目的は、ポリオレフィン樹脂にタルクや炭酸カ
ルシウムを混合しているにかかわらず不快臭のない食品
包装容器を提供することにある。An object of the present invention is to provide a food packaging container that does not have an unpleasant odor even though talc or calcium carbonate is mixed with the polyolefin resin.
〔問題点を解決するための手段］
本発明者らは、上記の目的を達成すべく鋭意研究した結
果、本発明に到達した。[Means for Solving the Problems] The present inventors have conducted extensive research to achieve the above object, and as a result, have arrived at the present invention.

らなる不快臭のない食品包装容器である。That is, the present invention provides talc and/or calcium carbonate 1
0-80% by weight and polyolefin resin 90-20% by weight
This food packaging container is free from unpleasant odors and is made of a resin composition containing 0.05 to 5 parts by weight of an antistatic agent and/or a lubricant per 100 parts by weight of the composition.

った容器が得られない。The ratio of polyolefin resin and inorganic filler is 10 to 80% by weight of inorganic filler and 90 to 20% by weight of polyolefin resin.
If the polyolefin resin is 90% by weight or more, the heat resistance will be poor when heated in a microwave oven or the like, and if it is less than 20% by weight, thermoforming will be difficult and a container with uniform wall thickness will not be obtained.

重量部未満では不快臭の防止効果が殆ど得られず、また
１０重量部を越える添加では添加剤の臭いが強くなり逆
に不快臭を生じるので好ましくない。These antistatic agents and lubricants may be added alone or in combination. The amount added is in the range of 0.05 to 5 parts by weight, preferably in the range of 0.1 to 3 parts by weight, based on a total of 100 parts by weight of the inorganic filler and polyolefin resin. 0.05
If it is less than 1 part by weight, the effect of preventing unpleasant odor will hardly be obtained, and if it is added in excess of 10 parts by weight, the odor of the additive will become strong and cause an unpleasant odor, which is not preferable.
