An optical cable and method for forming an optical cable is provided. The cable includes a cable jacket including an inner surface defining a channel and an outer surface and also includes a plurality of optical fibers located within the channel. The cable includes a seam within the cable jacket that couples together opposing longitudinal edges of a wrapped thermoplastic sheet which forms the cable jacket and maintains the cable jacket in the wrapped configuration around the plurality of optical fibers. The method includes forming an outer cable jacket by wrapping a sheet of thermoplastic material around a plurality of optical core elements. The method includes melting together portions of thermoplastic material of opposing longitudinal edges of the wrapped sheet such that a seam is formed holding the sheet of thermoplastic material in the wrapped configuration around the core elements.

Methods may include modifying the crystallization properties of a polymer composition including a polyolefin and a nucleating agent with the structure:

##STR00001## wherein R1 and R2 are independently hydrogen, alkyl, alkenyl, or aryl with the proviso that at least one of R1 or R2 is a carbon chain having 1 to 12 carbons with at least one of the carbons in the carbon chain covalently bound to the polyolefin, and wherein the alkyl, alkenyl, or aryl may be substituted with one or more carboxylate groups; and M is a metal selected from Group I of the Periodic Table.

There is provided container sealing apparatuses and methods for sealing openings of containers with film. The apparatuses comprise: a pressing member configured to press a film into contact with a container; and a sealing beam source configured to emit one or more sealing beams, each of said sealing beams being incident on the container and/or the film, each of said sealing beams being incident local to a respective part of the pressing member which engages the container so as to join the film to the container; the container sealing apparatus being configured to move the container relative to the pressing member, such that a region of the container which is engaged by the pressing member changes.

A biaxially-oriented film for thermoforming is disclosed including at least 75% by weight polyethylene and at least 95% by weight polyolefins, based on the total mass of the film. The polyethylene has an elongation at break of at least 7 in the stress-strain diagram, wherein the stress-strain diagram is measured at a temperature of 10° C. below the melting point of the polyethylene and the melting point is determined by differential scanning calorimetry using a heating rate of 10° C. per minute. A process for producing such films and to the use thereof are disclosed. A process for producing shaped bodies from such films and to the shaped bodies themselves are disclosed.

A method for manufacturing a foamed plastic molded body with a film layer coating by using a tool mold with at least one tool cavity to form a shaping mold cavity, including A) heating at least one tool cavity of the tool mold; B) applying a granulate to the at least one heated tool cavity; C) fusing the granulate in the heated tool cavity to form a liquid film layer; D) applying the liquid film layer to a foamed plastic molded body to form a film layer coating on the surface of the plastic molded body by fusing the liquid film layer with the surface of the plastic molded body; and E) cooling the at least one tool cavity and ejecting the plastic molded body coated with the film layer.

The present disclosure relates to a recyclable, padded paper mailer that is water resistant, heat sealable, and provides padded protection. The mailers in accordance with this disclosure find utility as padded mailing envelopes such as e-commerce mailers, bubble packaging pillows, or any other protective shipping packaging.
