The present disclosure provides a biodegradable and compostable multilayer film. The biodegradable and compostable multilayer film comprises a sealant product side layer comprising at least one slip additive and having a pre-determined co-efficient of friction, an outer surface layer, and at least one intermediate layer disposed between the sealant product 5 side layer and the outer surface layer. The biodegradable and compostable multilayer film of the present disclosure has good mechanical properties and is non-reactive with tobacco based products, medicines, and food products to be packaged.

A multilayer film can comprise: a plurality of layers, preferably 4 layers to 128 layers, comprising: a polymer A layer comprising a polycarbonate copolymer and a polymer B layer comprising a semi-crystalline polyester; wherein a differential solubility parameter (Δδ.sub.AB) of polymer A towards polymer B (Δδ.sub.AB) is greater than or equal to 2.6 MPa.sup.1/2; and an interdiffusion region between each polymer A and polymer B. The multilayer film has a dynamic flexure of greater than or equal to 200,000 cycles, as determine by bending 180° on a 10 mm radius cylinder at a rate of 1 hertz. The multilayer film has a total thickness of 40 μm to 70 μm, a transmission at 360 nm to 750 nm of greater than or equal to 89% and a haze of less than or equal to 1%.

Backing films for adhesive tapes are presented, as well as adhesive tapes comprising such backing films, which may include tapes used in construction such as seam sealing tapes, roofing tapes, and flashing tapes. The backing film comprises a core layer, a first skin layer, and optionally a second skin layer, where the backing film has a coefficient of thermal expansion of less than 90 ppm/° C. measured in at least one direction within the plane of the film, and, in some embodiments, a Young's modulus of less than 550 MPa as measured in at least one direction. In some embodiments, the backing film has a coefficient of thermal expansion of not more than 91.8 ppm/° C. and a Young's modulus of not more than 540 MPa as measured in any direction within the plane of the film. In some embodiments, the core layer comprises a polyolefin, and skin layers comprise a thermoplastic elastomer.

The apparatus (100) includes a die head (118) for extruding a main comestible material to form an extrudate body. A plurality of nozzles (160, FIG. 7) is located within the die head for introducing a comestible fluid into the extrudate body to form a plurality of filled capillaries. A control system (182) is capable of selectively connecting at least one of the nozzles to any one of at least two different fluid filling sources (150A, 15 OB). The control system may be capable of connecting each of the nozzles independently to different fluid sources or the nozzles may be arranged into two or more groups of flu idly interconnected nozzles that can each be independently switched between different fluid sources. The apparatus can be used to form products in which the fillings in the capillaries are varied or in which an image is formed in cross section. The apparatus can also be used to switch production between products having different fillings without stopping extrusion.

A blow molding method includes a primary blow molding step that molds a preform (200) in a primary blow mold (300A) that includes a primary temperature control section (330) to obtain an intermediate molded article (202), a shrinkage step that discharges blow air from the intermediate molded article to shrink the intermediate molded article, and a secondary blow molding step that blow-molds the intermediate molded article (204) that has shrunken in a secondary blow mold that includes a secondary temperature control section (430) to obtain a final molded article. The primary blow molding step cools a first intermediate molding region of the intermediate molded article that follows a neck using a first primary temperature control section, and the shrinkage step shrinks a second intermediate molding region of the intermediate molded article of which the temperature is controlled by a second primary temperature control section.

The present invention relates to an odor control material consisting of a water-insoluble particulate odor control agent and a thermoplastic water-soluble carrier matrix encapsulating the odor control agent. The carrier matrix dissolves when in contact with an aqueous solution, such as urine and the odor control material is obtained by means of thermoforming. The invention relates also to a method for the preparation of the odor control material and the use of the odor control material in absorbent products. The present odor control material minimizes dusting problems caused by particulate odor control agents in production processes.

The invention relates to a ringed tubular sheath which comprises a longitudinal strip which can be easily detached by a user, in particular manually. More specifically, the invention relates to a ringed tubular sheath comprising a sheath body (1) and a longitudinal strip (6) which are made of materials that substantially do not adhere to one another, the longitudinal strip (6) comprising, on each of its longitudinal sides, an upper projection (2, 8) and a lower projection (3, 9), between which a respective longitudinal edge (5, 7) of the sheath body (1) is fitted, this sheath being distinctive in that the longitudinal strip (6) is substantially in the shape of an arc of a ringed tube. The invention also relates to a manufacturing method and to the use of such a sheath.

Disclosed are various embodiments of an extruded expandable barrier, and various processes and systems for manufacturing the same. Using various extrusion processes to form an extruded expandable barrier allows for a reduction in tooling costs while also allowing more flexible barrier designs. Such designs can be specifically tailored for a particular cavity or cavities to ensure that the barrier fills the cavity after expansion. In addition, design changes can occur with little to no tooling changes.

A fishing rod that includes an elongated, tapered rod blank at least a portion of which is quadrilateral in cross section, the quadrilateral portion of the rod blank diminishing in cross-sectional area toward a tip end of the rod blank, the quadrilateral portion of the rod blank comprising a sandwich-structured composite of a core disposed between facings, the core less dense than the facings, the quadrilateral portion of rod blank less stiff in a casting direction than transverse to the casting direction; fishing line guides mounted at intervals along the length of the rod blank; a reel seat mounted at the base end of the rod blank; and a handle mounted at the base end of the rod blank adjacent to the reel seat.
