Abstract

A container molded from a fluid permeable plastic material wherein the wall of the molded container is made resistant to fluid transmission. A label has a barrier-coating resistant to fluid transmission and also has a heat-sensitive adhesive surface. The label is applied to the container during the molding of the container. The label is placed in the mold and then plastic heated to a temperature sufficient to activate the adhesive is introduced into the mold and forced against the wall of the mold and also against the label to form the container and at the same time to cause the label to adhere to the container thus formed. The formed container has a side wall with abruptly curved portions at upper, lower, and spaced side edges of the label to provide the container with a generally continuous outer surface at the junctions of the label edges with the side wall. The label becomes an integral part of the container and resists fluid transmission through the label area.
