``Means for Solving Problems'' Therefore, in the present invention, the
We have attempted to solve the above problem by making ELILINER from a chlorinated vinyl composition consisting of vinyl chloride resin, 40 to 120 parts of phthalate ester, and 2 to 2 degrees WL of epoxidized soybean oil. Ta.

以下、不発明の塩化ビニル組成物乞詳しく説明する。The uninvented vinyl chloride composition will be explained in detail below.

不発明の塩出ビニル組成物に用いられる塩化ビニル樹脂

The vinyl chloride resin used in the uninvented chlorinated vinyl composition has a degree of polymerization of 1,300 or more and 3,000 or less.

When the degree of polymerization of this resin is less than 1300, the heat resistance of the resulting chlorinated vinyl composition becomes opaque. Furthermore, if the degree of polymerization exceeds 300 (L), the degree of processing of the vinyl chloride composition becomes high and it becomes difficult to process it into a liner. As the vinyl chloride resin, one produced by a suspension polymerization method is preferably used.

Since it is odorless, it is preferably used because it does not reduce the commercial value of coffee, which is sensitive to aroma, and beverages that tend to have odors. ESO is also desirable in that it acts as a stabilizer to prevent thermal degradation of the resulting vinyl chloride composition.

For the sum of J, phthalate ester'& 40~12
It is desirable to add 0 weight IJits and epoxidized soybean oil in a range of 22 to 20 parts by weight. When the amount of phthalate ester added is less than 40 mt, the mt of epoxidized soybean oil added is 20 mt in order to make the resulting vinyl chloride composition have appropriate flexibility. If the if part is exceeded, the resulting composition will have an M odor, making it unsuitable as a liner material.

Also, the amount of phthalate added is 120! On the other hand, if the amount exceeds 2 parts by weight, the amount of epoxidized soybean oil added must be 2 parts by weight or less, which is not preferable because the resulting vinyl chloride composition will have insufficient heat resistance.
