Title:
MULTILAYER FILM AND CONTAINER
Document Type and Number:
WIPO Patent Application WO/2007/102336
Kind Code:
A1
Abstract:
Disclosed is a multilayer film excellent in heat resistance, sealing strength,
transparency, moisture impermeability and flexibility. Also disclosed is
a container. Specifically disclosed is a multilayer film comprising five layers
mainly composed of an ethylene/α-olefin copolymer. The densities of
the first layer and the third layer are both more than 0.950 g/cm3 but
not more than 0.970 g/cm3; or alternatively, the density of the first
layer is 0.0935-0.950 g/cm3 and the density of the third layer is more
than 0.950 g/cm3 but not more than 0.970 g/cm3, or the density
of the first layer is more than 0.950 g/cm3 but not more than 0.970 g/cm3
and the density of the third layer is 0.925-0.950 g/cm3. The densities
of the second layer and the fourth layer are both not more than 0.920 g/cm3,
and the density of the fifth layer is 0.925-0.940 g/cm3. A container
(16) is formed by using this multilayer film (10) in such a manner that the first
layer serves as an outer layer (17) of the container and the fifth layer serves
as an inner layer (18) of the container.
