Abstract: A non-durable flexible container can include a first film wall including a first portion comprising at least one first structural support member defined in the first film wall, and a second portion that is free of a structural support member. The container can further include a second film wall including at least one second structural support member defined in the second film wall, wherein at least a portion of the first structural support member is adjacent to at least a portion of the second structural support member to define a seam region, and a side of the seam region defines an edge of the non-durable flexible container. The container can also include a closed produce volume defined between first and second film walls; and a seam projecting outwardly from the seam region at an intersection of the first and second film walls.

Abstract: Non-durable self-supporting flexible containers with easily variable sizing. Line ups of flexible containers have similar sizes, shapes, and constructions, but hold differing amounts of fluent product at unexpected fill heights.

Abstract: A method for manufacturing a three-dimensional object includes steps of: a) providing a digital description of the object as a set of voxels; b) sequentially creating an actual set of voxels corresponding to the digital set of voxels; wherein at least one voxel comprises a composition comprising between about 35 and about 100 wt. % of a polymer selected from the group consisting of nonionic PEG homopolymers, PEG copolymers, and mixtures thereof; the polymer having an average molecular weight of between about 1,000 and about 95,000 AMU; and between about 0 and about 65 wt. % of a filler, wherein the filler is a solid at a temperature of above about 75 C, wherein the composition has a Melt Flow Index of between about 0.1 and about 50 g/10 min when measured at 70 C under a 1.2 kg load using a half-die according to ASTM D1238-13.

Abstract: A carousel-like continuous molding system includes an arrangement of inclined feed channels. Each of the feed channels has a controllable valve therein positioned upstream of an inlet to an associated mold cavity. The valve is controllable so that adjustments may be made in real time to achieve or maintain delivery of molten polymeric material to the mold cavity at constant pressure.

Abstract: A carousel-like continuous co-injection molding system includes an arrangement of upper and lower inclined feed channels. Each of the feed channels has a valve therein positioned upstream of an inlet to an associated mold cavity. The valve is controllable so that adjustments may be made in real time to achieve or maintain delivery of molten polymeric material to the mold cavity at constant pressure.

Abstract: A method of forming a flexible container can include folding a web or sheet to define one or more gussets in one or more regions of the flexible container. The gusset can be a continuous gusset or can be an interrupted gusset, having a seal disposed in the gusset.

Abstract: Flexible containers with product dispensing visibility. The containers may include: a multiple dose product volume; a structural support frame that supports the product volume in a stand-up orientation; a dispenser; and a flow channel in fluid communication with the product volume and the dispenser. The flow channel may be made from flexible materials forming a sealed leg of a gusset. Fluent product may flow from the product volume, through the flow channel, and out the dispenser when the container is externally compressed. The sealed leg of the gusset has a first side and a second side. The first side of the sealed leg of the gusset has opaque decoration that overlays substantially all of the flow channel, and the second side of the sealed leg of the gusset has one or more non-opaque portions that overlay the flow channel.

Abstract: A low constant pressure injection molding machine forms molded parts by injecting molten thermoplastic material into a mold cavity at low constant pressures of 6,000 psi and lower. As a result, the low constant pressure injection molding machine includes a mold formed of easily machineable material that is less costly and faster to manufacture than typical injection molds.

Abstract: Disclosed herein is a method of injection molding at low, substantially constant melt pressures. Embodiments of the disclosed method now make possible a method of injection molding that is more energy—and cost—effective than conventional high-velocity injection molding processes. Embodiments of the disclosed method surprisingly allow for the filling of a mold cavity at low melt pressure without undesirable premature hardening of the thermoplastic material in the mold cavity and without the need for maintaining a constant temperature or heated mold cavity. Heretofore, it would not have been expected that a constant pressure method could be performed at low pressure without such premature hardening of the thermoplastic material when using an unheated mold cavity or cooled mold cavity.
