Abstract: A fluorinated polypropylene container having a wall defining an interior and an exterior of the container, at least a portion of the wall having a plurality of layers including a first layer including polypropylene, and a second layer on the first layer, the second layer includes polyethylene and having a fluorinated surface facing an interior of the container.

Abstract: A container incorporating post-consumer recycled (“PCR”) plastic and a method of making that type of container. The container utilizes a layer of polypropylene or EVOH or a film of fluorinated polyethylene toward the interior from the recycled plastic to prevent contaminants from the latter entering the container's contents. When utilizing EVOH, the container usually has an additional layer of polyethylene or polypropylene covering the EVOH to prevent its deterioration by moisture. Making the container involves first composing a resin including the recycled plastic. Forming the various layers listed above produces a container that includes recycled plastic and a barrier to limit the migration of contaminants from the recycled material to the container's contents. This permits the use of the resulting containers for food. For a fluorinated polyethylene film, fluorination can occur either during or after the container's formation.

Abstract: A plastic container having a thin outer layer that protects against stress concentration effects arising from either surface irregularities or flexing when dropped and a method of making that container. The outer layer helps avoid bottle failure resulting from cracks that start at such areas of stress. The outer layer may incorporate both the stress inducing irregularities and the properties to minimize possible, resulting catastrophes. The surface irregularities giving birth to stress include edges of in-mold-applied labels, ridges, stippling, and grip bumps. Dropping the container gives rise to flexing which can also induce stress concentrations. The outer layer, to accomplish the protective function, should display lesser brittleness or, in some cases, lesser density than the bulk of the container wall. Making the container involves forming the bulk of the wall with a first, inner, structural plastic.

Abstract: A container with improved crease-crack resistance and a method of making that type of container. The container utilizes a layer of a soft plastic on its exterior to control cracking at outward creases. When the container holds motor oil, the oil itself may plasticize the stiff material on the container's interior to preclude inward crease cracking. In this case, the stiff layer should have a sufficient thickness that an adequate amount of material remains unaffected by the oil and does not lose its rigidity or jeopardize the container's structural integrity. Where the contents do not provide the requisite improvement in inward crease cracking or would completely soften the stiff layer, then the container has a separate, soft, third layer of plastic on the interior of the container. The softness of this layer protects against inward crease cracking. It may also protect the stiff layer from softening by the bottle's contents.

Abstract: A polyester or copolyester container is made with a heat activated high barrier copolyester label applied to the container sidewall. The process for producing the high barrier container that is a hollow polyester or copolyester body with a barrier label effectively applied to its outer sidewall, includes forming the container by an extrusion blow method, injection blow method, orientation-blow method, or orientation blow-heat set method and applying the barrier label via an "in-mold" technique utilizing a heat-activatable high barrier copolyester resin as the adhesive.
