The present invention relates to a multilayer, polyolefin-based packaging film which does not contain any polyamides or polyesters and to a method to manufacture such film through the Triple Bubble technology. The present invention also relates to the use of such film for packaging products, especially food products and to the packages obtained with such film.

A needle shield remover for a medicament delivery device is presented that has a metal tubular body, a proximal part, a distal part, and a substantially circular cross-section, where the tubular body is arranged with a slot extending from a distal end of the body, at least half the length of the body, towards a proximal end, such that at least the distal part of the body may flex radially outwards to exert a radially inwardly directed clamping force on a needle shield accommodated by the body.

Methods and systems herein relate to forming an upper dental appliance chassis including at least two upper appliance button protrusions; forming a lower dental appliance chassis including at least two lower appliance button protrusions and at least two vertical displacement bite pads; injection overmolding a first thermoplastic on the upper dental appliance chassis to provide a first reformable thermoplastic layer integrated with the upper dental appliance chassis that exposes the at least two upper appliance button protrusions to form an upper dental tray; and injection overmolding a second thermoplastic on the upper dental appliance chassis to provide a second reformable thermoplastic layer integrated with the lower dental appliance chassis that exposes the at least two lower appliance button protrusions and the at least two vertical displacement bite pads to form a bottom dental tray.

In one example embodiment, disclosed is a biaxially oriented multilayer film, which may include a first tie layer and a second tie layer, wherein each has an inside surface and an outside surface. The film's core layer may consist of: (i) at least 50 wt. % high-crystalline polypropylene; (ii) both cyclic olefin copolymer and polypropylene homopolymer, or, polypropylene heterophasic copolymer; (iii) and, optionally, additives, wherein the core layer is between the inside surface of the first tie layer and the inside surface of the second tie layer. The film may also include a first skin layer on the outside surface of the first tie layer and a second skin layer on the outside surface of the second tie layer, wherein shrinkage is less than 3.5% in a transverse direction for the biaxially oriented multilayer film after subjecting the biaxially oriented multilayer film to 135° C. for 7 min at 1 atm.

A method of joining overlapping thermoplastic geomembrane components in which a first thermoplastic geomembrane component and a second thermoplastic geomembrane component are positioned in overlapping relationship between a pair of complementary molding surfaces, with one or more of the complementary molding surfaces being defined by an electrically conductive metal susceptor. Heat is generated in the metal susceptor and transferred by thermal conduction from the metal susceptor to overlapping portions of the first and second thermoplastic geomembrane components to locally melt and coalesce a portion or more of the thermoplastic material of the first thermoplastic geomembrane component and a portion or more of the thermoplastic material of the second thermoplastic geomembrane component. The molten thermoplastic material of the first and second thermoplastic geomembrane components forms a zone of coalesced thermoplastic material that, upon cooling, forms a solid weld joint.
