Deep-drawing packaging container, deep-drawing package, and method for production of the packaging container or the package

摘要

A deep drawing packaging container comprising: a top film made of a first heat shrinkable multilayer film; and a bottom film made of a second heat shrinkable multilayer film, the deep drawing packaging container being formed by deep drawing, so that a drawing ratio (D 1 ) of the top film and a drawing ratio (D 2 ) of the bottom film satisfy conditions:
D 1 = 1.1 to 4.0;
D 2 = 1.5 to 5.0; and
(D 2 /D 1 ) = 1.05 to 4.55,
wherein a hot-water shrinkability (S M1 ) in a longitudinal direction and a hot-water shrinkability (S T1 ) in a transverse direction of the first heat shrinkable multilayer film and a hot-water shrinkability (S M2 ) in a longitudinal direction and a hot-water shrinkability (S T2 ) in a transverse direction of the second heat shrinkable multilayer film satisfy conditions:
S M1 = 5 to 40%;
S T1 = 5 to 40%;
S M2 = 2 to 25%;
S T2 = 2 to 25%;
(S M1 /S M2 ) = 1.2 to 12; and
(S T1 /S T2 ) = 1.2 to 12
(where the hot-water shrinkability is a shrinkability (%) after immersing the heat shrinkable multilayer film before drawing in hot water of 90°C for 10 seconds).
