Peelable Pouches
Appearances matter, even in the medical industry.
So when operating room doctors at an Austin, Tex. hospital expressed their desire for a new style of peelable chevron header pouch — used to seal three-dimensional objects intended for use during surgery — flexible packager Rollprint Packaging responded with its new Duet product.
The Duet pouch is manufactured by heat sealing a strip of DuPonts Tyvek high-density polyethylene film to a polyester/ extrusion-coated sealant to create the first side of the structure. The next step is to three-side, heat-seal the Tyvek/film combination to a layer of polyester/poly. At the bottom, the polyester/extrusion-coated layer extends slightly beyond the polyester/poly film side, creating access tabs at both corners where a dual chevron-opening feature has been created.
According to Rollprint Packaging, the dual chevron at the outer edge makes it easier for operating room personnel — used to having only one opening option — to open and remove such objects as trays, tubing and various kits without flaps potentially compromising the aseptic presentation.
Marking application for medical lasers
For surgeons using medical laser equipment to perform painstaking high precision surgical techniques and soft tissue surgery, marking labels are a critical component for indicating the remaining number of reuse cycles of the reusable light conductors in the laser equipment.
For this reason, Dornier MedTech, a Kennesaw, Ga.-based laser design company, selected Victrex APTIV film, made with PEEK polymer from Victrex, for the marking labels in its high-quality solid-state lasers.
According to Victrex, APTIV film offers high dimensional stability, excellent mechanical properties and a maximum continuous use temperature of up to 220°C, making it ideal for the steam sterilization resistance (conducted at an average temperature of 134°C) necessary for reusable medical instruments. In addition, the film provides resistance to aggressive media such as cleaning and disinfecting agents used in demanding laser surgery environments, and can be readily printed upon using laser marking as well as a number of other conventional printing techniques.
Resin enables flexible prosthetic foot design
Life may have gotten a little easier for those crippled by landmine explosions, thanks to the new Niagara Foot highperformance prosthetic foot, designed as part of a landmine victims relief program by Ont.-based Niagara Prosthetic & Orthotics International Ltd.
Featuring flexibility made possible by DuPonts Hytrel thermoplastic polyester elastomer, the Niagara Foot is capable of supporting an individual weighing up to 80 kilograms of plastic molding. A key aspect of its design lies in its keel — a single, Sshaped part, injection molding part from Hytrel 8238, that acts like a spring to provide energy storage and return to the wearer while walking. According to DuPont, while a number of other materials, including poloxymethylenes (POM) and polyamides, were unable to carry an 80 kilogram load without deformation — as required by ISO 10328 standards — Hytrel 8238 exceeded this load during tests carried out at Queens University in Kingston, Ont.
