Abstract: The instant invention relates to processes for producing tamper-evident overwrapped packages as well as the products which are produced. These processes utilize various energizing sources to create tamper-evident patterns between the package surface and the underside of the clear overwrap film closure. Tamper-evident patterns can also be created between heat-sealed overlapping sections of the overwrap film.

Abstract: A method and apparatus for automated smoking to replicate a predetermined draw profile of a smoking article is disclosed. In preferred embodiments, the smoking apparatus is digitally controlled and includes simulated flexible lips which are closed during puff phases of a recorded draw profile and which are open during smolder phases of a recorded draw profile. The apparatus can also include an automatically acting lighter and an improved control system for a human mimic smoking machine.

Abstract: The invention is directed to a packaging composite for barrier sealed cigarette or other smoking article packages. The composite includes a foil layer, exterior and interior skin layers of heat-sealable thermoplastic polymer, first and second biaxially oriented polypropylene homopolymer layers located between the exterior skin layers and the foil layers, and first and second adhesive layers coupling the polypropylene layers to the foil layer on each side thereof. The package laminate has a thickness of between 1.5 and 2.5 mils.

Abstract: The invention provides a packaging laminate which is heat sealable to polypropylene, high density polyethylene or linear low density polyethylene to provide a strong seal which is cleanly peelable at the heat seal interface under hand pressure. The laminate has at least two layers. A heat sealable surface layer is composed of a melt blend comprising between about 55 and 95 wt. % of a substantially linear polyolefin and between about 5 and about 45 wt. % of a polyolefin rubber. The second layer is a heat stable layer which is structurally stable at temperatures in excess of 350.degree. F. or greater and which has sufficient thickness to provide structural stability during heat sealing.

Abstract: In one aspect, the invention provides a simple, readily manufacturable, low tar cigarette with individual puff deliveries similar to those obtained from conventional cigarettes which have a higher total smoke delivery such as a full flavor cigarette. The low tar cigarette includes a tobacco rod segment having a length of 53 mm. or less abutting a filter segment having an overall length of at least 31 mm. wherein the filter segment includes a synthetic fiber filter plug and provides a smoke delivery reduction of at least 55% and wherein the cigarette has an average puff count of 6.5 or less. In another aspect, the invention provides nonconventional smoking articles which have an elongated nonsmokable mouthend portion, i.e.

Abstract: Molten polymer streams are separately metered to the individual capillaries of a combined orifice, rendering the yarn produced less dependent on the capillary dimensions.

Abstract: Two molten streams of polyester polymer are extruded at different speeds to intersect below the spinneret. The spinning speed is relatively high, and the resulting filament has shrinkage peaks and valleys along its length. When a number of such filaments are relaxed in a yarn bundle, the yarn spontaneously develops crimp.
