An Ohio company that offers document services is entering the in-mold labeling market with what might be a major technology play. Competitive in-mold offerings generally use identical materials such as polycarbonate label with a polycarbonate part or a polystyrene label with polystyrene part. Compatible melt indexes are critical, creating complications when a plastic is highly filled. “A lot of work goes into matching the like label with a part to insure it bonds well and looks good,” says David Coughlin, director of operations of Industramark, which is being introduced at the National Plastics Exposition this week in Chicago. “This truly is a challenge and a good part of the reason why in-mold labels have not taken off outside of prime labeling applications that are typically only polypropylene.” Working with Fusion Graphics, also of Dayton, OH, Industramark has developed a 7 mil micro porous film. “We do not depend on like chemistries for bonding but rather the plastic (any thermoplastic) being molded flows into the micro bonds and makes a permanent bond to the label. Based on our relationship with Fusion Graphics and their patent position, we have a novel solution that makes other in-mold products obsolete and very complex.”
Labels are not new to Industramark’s parent, Standard Register. They accounted for 13 percent of revenues last year. In response to a question from Design News, Industramark did not provide information on the material used for its in mold labels. A patent awarded to Robert Freund of Waynesville, OH in 2007 describes a new IML technique based on a precipitated silica-filled microporous sheet material. If properly coated, the material is well suited to the IML task, according to the patent. The novel system also requires special inks. The technique is said to not only to improve quality of graphic images, but also to cost less. A wide range of materials, including thermosets, can be used.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
