Void-containing polyester shrink film
InactiveUS20050119359A1Improve performanceHigh opacitySynthetic resin layered productsLabelsPolyesterVolumetric Mass Density
Disclosed are polyester shrink films comprising a voiding agent dispersed within a continuous polyester phase. The voiding agent comprises at least one first polymer and at least one second polymer, in which the polymer components have selected physical properties such as glass transition temperature, melting point, tensile modulus, surface tension, and melt viscosity. The resulting shrink films have high opacity, a low coefficient of friction, lower density, low shrink force, and good printability. The films are useful for sleeve label and other shrink film applications, and their lower density allows them to be readily separated from soft drink bottles, food containers and the like during recycling operations. Also disclosed is a process for separating a void-containing polyester from a mixture of polymers.

High-start spring energized stapler
ActiveUS20070175946A1Enhanced handle travelGreat leverageStapling toolsNailing toolsRest positionEngineering
A spring energized stapler includes a “high start” design wherein a striker has a rest position above the staple track. A handle is pressed to energize a power spring while the striker remains stationary. At a predetermined position of the handle, the striker is released to eject a staple. A subassembly of a cage and the power spring provides a preload to the power spring in the rest position. The subassembly is separately movable from the handle to allow a handle pressing end to move farther than the striker's distance of travel. The handle includes a movable pivot location to enable enhanced motion of the handle pressing end. Alternatively, an optional lever links the striker to the power spring to provide leverage upon the power spring. A release latch may be mounted in front of the striker to be engaged by the lever or the handle.
