<p>PROBLEM TO BE SOLVED: To prevent the contained amount from being reduced due to adsorption of fat-soluble vitamins to container, by using a plastic containing polyethylene naphthalate in the parts in contact with the composition in the container in which composition containing fat-soluble vitamins filled. SOLUTION: In containers containing such fat-soluble vitamins as vitamin-E, vitamin-A, etc., a plastic containing polyethylene naphthalate is used in the parts in contact with the composition, to make it possible to prevent the fat- soluble vitamins from being adsorbed to the parts in contact with the composition. This plastic sheet containing polyethylene naphthalate to be used is most preferable to consist of polyethylene naphthalate only. For enhancing the formability, as required, a resin to which polyethylene telephthalate is added, and the like, or copolymer of polyethylene telephthalate and polyethylene naphthalate may be used.</p> |
