Curved heat shrink tubing and methods of making the same are described herein. An example method includes inserting heat shrink tubing into a tube, curving the tube, and deforming the heat shrink tubing, inside of the tube, to have a curved shape along a length of the heat shrink tubing where a first length of the heat shrink tubing along an outer radius of the curved shape is longer than a second length of the heat shrink tubing along an inner radius of the curved shape.

The present invention provides a multilayer packaging film characterized by an improved sealability even through contamination with excellent shrinkability good optics and strength without using internal layers of stiff resins and cross-linking, to flexible containers made therefrom, such as bags, pouches and the like, useful for packaging articles, in particular food items.

Provided are molds for polar anisotropic ring-shaped bonded magnet molded articles which enable the production of bonded magnet molded articles with a high degree of roundness and only slight distortion, without the need for mold modification and preparation of a test mold, and a method of preparing such molds. The present invention relates to a method of preparing a mold for a polar anisotropic ring-shaped bonded magnet molded article, the method including: 1) determining the shrinkage length (Tc) of a desired polar anisotropic ring-shaped bonded magnet molded article using the following equation: Tc=Tx(1/1002/100); 2) determining the radius (Dm) of a magnetic pole portion of a mold cavity using the following equation: Dm=D/(12/100); and 3) defining the outer peripheral shape of the mold cavity from the Tc, the Dm, and the number (P) of magnetic poles of the molded article.

A method for expanding an end of a pipe made of plastics having shape memory with the aid of an expander tool having a tool head having an expansion member arranged to be insertable inside the end of the pipe. The method includes steps of measuring the temperature of the pipe to be expanded, adjusting at least one of the expansion control parameters of the tool head on the basis the measured temperature of the pipe, and expanding the end of the pipe utilizing the adjusted expansion control parameter of the tool head. The expander tool includes a temperature sensor for measuring temperature of the pipe to be expanded and/or ambient temperature, and an electronic control unit for adjusting at least one of the expansion control parameters of the tool head on the basis the measured temperature value.

A method and apparatus for forming a tool is provided. A number of members comprised of a thermoplastic material is positioned within a hollow portion of a structure. The tool is formed within the hollow portion of the structure with the number of members positioned within the hollow portion of the structure. Heat is applied within a selected range to the number of members to reduce a size of each of the number of members. The number of members is removed from the tool such that the tool is left with a number of voids.

The inventors have discovered that certain hot melt adhesives can be used to form a stable stacked pallet that can limit the need for additional packaging materials e.g. inter-layer and pallet wrap.

Provided are a heat-shrinkable polyester-based label, and a package which each have a solvent-bonded portion where no solvent permeation-through is caused even when a film of the label is small in thickness. Provided are, in particular, a heat-shrinkable polyester-based label and a package which each have a solvent-bonded portion giving a high peel strength stably even through a high-speed tubing step, or even when the film is a heat-shrinkable polyester-based film in which a PET-bottle-recycled material is used in a large proportion. The label is a heat-shrinkable polyester-based label that is a tubular label in which both end portions of a heat-shrinkable polyester-based film are bonded to each other with a solvent composition. In this label, the solvent composition is a solvent composition containing at least 1,3-dioxolane and/or tetrahydrofuran (THF), and a polyester, and the end portion bonded has a peel strength of 2 N/15 mm or more.

A heat shrinkable tube has a hollow tubular shape and includes an outer peripheral surface, an inner peripheral surface, and a plurality of protruded portions provided on the inner peripheral surface and extending in directions intersecting with each other.

A method of assembly includes providing a sensor having an electronic sensing unit operable to emit or receive light rays and a clear substrate attached to the electronic sensing unit. The method also includes providing a tubular protective wrap having a central orifice. The protective wrap has a transparent film layer and an interstitial layer. The interstitial layer is disposed on an interior surface of the film layer proximate the orifice. The method additionally includes disposing the protective wrap about the electronic sensing unit. The method further includes shrinking the protective wrap via application of heat such that the interstitial layer contacts at least a portion of the sensor with the film layer superposed over at least a portion of the clear substrate.

A moisture wicking heat shrink sleeve for aircraft cabin moisture control incorporates a heat shrinkable tube of predetermined length receivable over a structural member. A moisture absorbing layer is adhered to a surface of the heat shrinkable tube with the heat shrinkable tube and adhered moisture absorbing layer configured for radial contraction from a first expanded condition to a second contracted condition upon application of heat.
