A paper container is produced that has gas barrier properties, by employing a
laminate
having at least a (I) paper layer 101, a (II) gas barrier layer 103,
and an (III) epoxy-group-containing resin composition layer 104. The
(III) epoxy-group-containing resin composition layer consists of a resin composition
that contains a polyolefin (a) having a melt flow rate of 0.1100 g/min and
an epoxy-compound (b) which has two or more epoxy groups in the molecule and has
a molecular weight of 3000 or less, epoxy-compound (b) being added in an amount
of 0.015 parts by weight with respect to 100 parts by weight of polyolefin
(a). This (III) epoxy-group-containing resin composition layer has good adhesion
with the (II) gas barrier layer, thus a laminate can be produced without employing
a dry laminate adhesive agent or an extrusion laminate anchor agent. Accordingly,
it is possible to avoid a deterioration in the work environment or an odor remaining
in the final product from the use of organic solvents. As a result, a paper container
having a good adhesive strength between the layers and superior gas barrier properties
can be obtained.
