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.

Tim, this material is specifically targeted for large-scale agricultural applications, as an alternative to poisonous sprays like Roundup and genetically modified (GM) crops. So is black petro-based plastic, but this material has even more benefits, since it can be plowed under, saving time and cost of removal, and saving the damage done if not removed.
Hopefully, this film is available to be applied in a large scale application. Many large scale farm plants have been genetically engineered to specifically resist herbicides (ie Round Up Ready Corn). This allows the farmers to spray the entire field to kill weeds while retaining their cash crop. If this film allows for the farmer to reduce the amount of herbicide and geneticallly engineered seed, it would only be a net gain to consumers.
Chuck, that appears to be lettuce or some other leafy vegetable. The thin film is mulch, which you put down around your crop plants to help keep down weeds and retain moisture in the soil. Many people use large sheets of black petro-based plastic, which is highly effective but does not biodegrade quickly and can leave harmful residues. I'm a gardener, not a largescale farmer, but I suspect it's put down before or during planting not after and holes punched through for the plants.
Tim, you are correct, it was the same material. In the instance I described, the bags in question were pre-formed to run on the type of machinery that packages sliced bread.
Can you imagine that material when making your kids' lunch sandwiches?
These may have been the same bags that Frito Lay introduced for their Sun Chips in 2010. They were so noisy and had a such a bad feel that the Sun Chip sales actually fell about 10% during the year that they were on the market. It would be great to see a non-noisy solution that would be bidegradable.
TJ, thanks for that input. I heard from several manufacturers of bioplastics and/or recyclable plastics (the BASF Ecoflex/Ecovio peanuts bag is both) that they had spent considerable time and effort getting feedback from users to overcome exactly the unpleasant characteristics you described. The BASF peanuts bag, for example, is not noisy like cellophane when you manipulate it and that specific problem was cited as one they had worked to overcome. So things have changed quite a bit in four years and these materials now exist--I've seen them--but they haven't yet been adopted in quantities that make them visible to end-users.
And of course, making so-called green materials from food crops, especially corn, is now a no-no.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
Design engineers play a big role in selecting both suppliers and materials for their designs. Our most recent Design News Materials Survey says they continue to be highly involved, in some ways even more than the last time we asked to peek inside their cubicles.
Daihatsu is one of the first carmakers to customize car exteriors using 3D printing's mass customization capabilities. Effect Skins -- small exterior bumper and fender panels in different colors and textures -- can be ordered for its Copen convertible.
Several new products in this group of new adhesives, coatings, and sealants are formulated to protect sensitive electronic components, or to seal components of commercial and military aircraft. Others are designed to operate in tough, messy, dirty oil & gas operations, or for rotary applications and motors.
