Blow-molded container, fuel container, blow-molded bottle container, and production method of blow-molded container |
摘要 |
Provided is a blow-molded container exhibiting inhibited coloring, odor, and generation of defects such as gelation and streaks which are caused on melt molding, and having a superior appearance. Also provided is a blow-molded container that has a favorable self-purge feature in production and satisfactory qualities such as strength, and can be produced at low cost. The blow-molded container includes a first layer containing an ethylene-vinyl alcohol copolymer (I), wherein the first layer contains a saturated carbonyl compound (II) having 3 to 8 carbon atoms, the saturated carbonyl compound (II) is a saturated aldehyde (II-1), a saturated ketone (II-2) or a combination thereof, and the content of the saturated carbonyl compound (II) in the first layer is 0.01 ppm or greater and 100 ppm or less. |
