Compared to other Plexiglas formulations, bio-based Rnew-maker Altuglas says it has greater melt flow and lower processing temperatures. Its properties, including impact resistance and chemical resistance, can be tailored, and it can be first extruded, then thermoformed with a high degree of detail, as shown here.

Beth, I also live in the country and I also see plastic litter on the roadside. In fact, I carry a trash bag, pick it up and bring it back to recycle. I can't understand littering, either: I used to go backpacking and the rule I learned is make it look like you were never there. At least if plastic trash is biodegradable it won't take an extremely long time for the plastic to break down and become harmless constituents of the ecosystem.
A green plastic films manufacturer stopped by the PackExpo booth of my company about four years ago, with some sample preformed bags. They wanted to test their bags on our equipment. We were happy to run the test right there.
The bags were incredibly stiff and "hard" compared to regular LDPE packaging material. This material sounded like cellophane when handling it (lots of LOUD crackling crunching noise). The material was also very, very fragile. It had no stretch, no give. Stress it just a bit, and it rapidly tore.
It was green (made from corn), and would degrade readily, but it wasn't very usable for packaging. There's still a lot of work to be done in the field to make a usable green material for packaging.
Cool slide show, Ann. I particularly liked seeing the BASF materials being used in food packaging applications. All you have to do is take a walk (I live out in the country and it's still a problem) and it's an eye opener to see the cups, bottles, and fast food trash littering the sides of the road. Given that it's harder to change people's behavior (although I can't understand littering, but that's a totally separate issue), it's comforting to know progress is being made on creating products that will be a bit easier on the environment.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
