A reclosable pouch that includes a receptacle having a storage chamber and a mouth in communication with the storage chamber, a hermetically sealable closure attached to the mouth, the closure including a first zipper strip and a second zipper strip, the first and second zipper strips being fused together in first and second zones situated at respective ends of the closure, a slider mounted to the closure, and a respective pair of round projections arranged back to back on first and second walls of the receptacle. The round projections are separate and distinct from each other and from zipper terminations of the first and second zippers, and the respective pair of round projections prevents further travel of the slider at opposing ends of the closure upon contact with sidewalls of the slider.

A battery separator comprises a co-extruded, microporous membrane having at least two layers made of extrudable polymers and having: a uniform thickness defined by a standard deviation of <0.80 microns (?m); or an interply adhesion as defined by a peel strength >60 grams.

A resin end-face butt joint, a method for welding the joints, and a piping member ensure a sufficient clamping margin with the clamp of an ordinary welding machine, and ensure an appropriate distance between the centers even when joints having short tubular welding ring parts are welded. It is also possible to align the centers by positioning the centers along the same axis. The resin end-face butt joint includes multiple welding ring parts which communicate with a flow path within a joint base part and which are provided on the joint base part. Fastening parts are coaxial with at least one of these welding ring parts at the outer end of the joint for the purpose of clamping a welding machine.

According to an aspect of the present disclosure, an adjustable induction foil sealing device is used to hermetically seal a container. The device can be adjusted to accommodate differently sized containers. The device includes a power supply cabinet, first and second rail assemblies and an adjustment assembly coupling the rail assemblies together and coupling the rail assemblies to the cabinet. Each rail assembly has an induction sealing coil and conductive contacts. The contacts on the rail assemblies are in electrical contact with the contacts on the cabinet. The adjustment assembly is configured to adjust the relative positions of the rail assemblies relative to each other and relative to the cabinet, while maintaining the electrical connection of the contacts.
