An apparatus comprising: (a) a mandrel; (b) an internal guide spaced apart from the mandrel; (c) an external guide extending around all or a portion of the internal guide and being spaced apart from the mandrel; wherein a pipe extends between the internal guide and the external guide and then over the mandrel so that the mandrel changes one or more dimensions of the pipe.

Mandrel and support assembly

The disclosure provides for a method including: a) forming a layered tubular member () by placing one or more outer layers () about an inner layer () and joining at one or more seams () along a length of the layered tubular member, wherein the one or more outer layers include a first resin impregnated therein; b) applying the first resin or a second resin at the one or more seams; c) creating one or more fillets () along the one or more seams with the first resin, the second resin, or an adhesive; and d) curing the first resin, the second resin, and the adhesive so that the layered tubular member, the first resin, the second resin, and the adhesive form a composite structure having a tubular shape.

Tubular composite structures and methods of molding such structures

The present disclosure provides a flexible container. In an embodiment, the flexible container includes a first multilayer film and a second multilayer film. Each multilayer film comprises a seal layer. The multilayer films are arranged such that the seal layers oppose each other and the second multilayer film is superimposed on the first multilayer film. The multilayer films are sealed along a common peripheral edge. The flexible container includes a fitment. The fitment comprises a base. The base comprises a polymeric blend of from 60 wt % to 90 wt % ethylene/&#x3b1;-olefin multi-block copolymer and from 40 wt % to 10 wt % high density polyethylene (HDPE). The flexible container includes a fitment seal comprising the base located between the multilayer films. The base is sealed to each multilayer film at a portion of the common peripheral edge.

Flexible fitment for flexible container

The present disclosure provides a seal bar. In an embodiment, the seal bar comprises a base member having a flat front surface and a flat recessed surface a distance (d) behind the front surface. The front surface defines an x-axis, X. The flat recessed surface has a first endpoint (A), wherein an axis that is perpendicular to the flat recessed surface at the first endpoint (A) defines a first y-axis (Y). The seal bar has a concave surface extending the distance (d) between the first endpoint (A) and a point (B) on the flat front surface. The concave surface defines a quadrant arc segment of an ellipse between the first endpoint (A) and the point (B).
