Abstract: Resorbable implants, coverings and receptacles comprising poly(butylene succinate) and copolymers thereof have been developed. The implants are preferably sterilized, and contain less than 20 endotoxin units per device as determined by the limulus amebocyte lysate (LAL) assay, and are particularly suitable for use in procedures where prolonged strength retention is necessary, and can include one or more bioactive agents. The implants may be made from fibers and meshes of poly(butylene succinate) and copolymers thereof, or by 3d printing molding, pultrusion or other melt or solvent processing method. The implants, or the fibers preset therein, may be oriented. These coverings and receptacles may be used to hold, or partially/fully cover, devices such as pacemakers and neurostimulators. The coverings, receptacles and implants described herein, may be made from meshes, webs, lattices, non-wovens, films, fibers, foams, molded, pultruded, machined and 3D printed forms.

Abstract: A microporous membrane is made by a dry-stretch process and has substantially round shaped pores and a ratio of machine direction tensile strength to transverse direction tensile strength in the range of 0.5 to 5.0. The method of making the foregoing microporous membrane includes the steps of: extruding a polymer into a nonporous precursor, and biaxially stretching the nonporous precursor, the biaxial stretching including a machine direction stretching and a transverse direction stretching, the transverse direction stretching including a simultaneous controlled machine direction relax.

Abstract: A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane.

Abstract: A compostable laminated packaging film comprises a first cellulosic layer having a first major surface and a second major surface opposite the first major surface, the first major surface of the first cellulosic layer configured to face away from a product to be packaged. A second cellulosic layer has a first major surface and a second major surface opposite the first major surface, wherein the first major surface of the second cellulosic layer is configured to face toward a product to be packaged. The second major surface of the first cellulosic layer and the second major surface of the second cellulosic layer have been surface-treated to enhance adhesion properties. A compostable polymer layer and an optional adhesive layer are disposed intermediate the first cellulosic layer and the second cellulosic layer.
