Plastics Today
Plastic injection processing has experienced massive change in the last 20 years. The days of molding by time and pressure have given way to molding by position, peak pressure and process repeatability. Don Paulson, RJG and John Bozzelli were major pioneers in the development of decoupled and scientific molding, as the procedures were developed and given structure. Plastic injection as an art gave way to plastics processing as a science of repeatability and standardization.

 In mechanical systems with moving components, friction can increase energy consumption and lead to surface degradation of the components. Minimizing friction is therefore an important aim, and the proper selection of materials for use in these systems is key to achieving it. Polytetrafluoroethylene (PTFE) is one of several materials that have intrinsically low friction, and can be used as an alternative to liquid lubrication in situations where such lubrication is not effective (e.g., in high-vacuum or ultraclean environments).

The market for plastic caps and closures is still growing, driven by changing population demographics, new technology and trends like improved packaging sustainability. The sector is an important one for Dow Chemical Co., which launched a new brand for its portfolio of polyethylene resins for cap, closure and fitment applications at the Plastics Caps & Closures conference in Chicago.

A new U.S. study has revealed that plastic bottle makers can use up to 50 percent recycled PET (rPET) content in hot-fill bottles without causing a "significant adverse impact" on the containers' integrity. Research by design and technology company Plastic Technologies (PTI) of the US delved into the issue of rPET because the company said brand owners continued to look for ways to lower their carbon footprints.

The U.S. plastics industry remains one of the few manufacturing sectors with a trade surplus, according to the latest edition of an annual report from the Society of the Plastics Industry Inc. SPI officials said the report — which analyzes trade data from 2015 – "paints a complex, but ultimately positive and promising, portrait of the U.S. plastics industry." The industry's trade surplus fell 32 percent to $7.1 billion in 2015, largely because of lower selling prices for plastic resin. As in previous years, all of the industry's surplus comes from resin, with trade deficits continuing in plastic products, molds and machinery.

Jack Piper and his colleagues at Dresden Optics Pty. Ltd. in Australia want to put a new face on the business of eyeglasses. At the same time, they believe strongly in environmental stewardship and a circular economy. And so they’re doing their modest bit to drive that concept forward – one set of recyclable glasses at a time. The company's co-founders – Bruce Jeffreys and Jason McDermott – describe themselves as frustrated glasses – wearers. Because, they note, glasses are annoying. "You lose them, you break them. You scratch them. You forget them. They're fragile, expensive and hopelessly inconvenient."

French automobile manufacturer Renault has begun using a bio-based engineering plastic for the outer mask of the speedometer-tachometer combo for the dashboard of the Clio. Renault’s fourth-generation Clio supermini was introduced in 2012, but has been subject to a mid-cycle refresh in June 2016. The material for the dashboard part has been supplied by the Japanese chemical firm Mitsubishi Chemical Corporation (MCC). Renault is the first European car maker to use MCC’s Durabio bio-based engineering plastic.

Innovia Films is expanding its portfolio of peelable biaxially oriented polypropylene (BOPP) films to help alleviate the frustration of consumers trying to pry open plastic packaging. Propafilm RCP, which is now available in 52 and 60 microns, is a proven, easy-to-open, food packaging film range that now includes heavy duty, high barrier and snap wrap options. The main benefit of using Propafilm RCP is that its seals are a breeze to open.

For a while now, superbugs have been a problem in the science world. This is due to their resistance to antibiotics. But here's good news: Experts are currently testing a new approach that uses star-shaped polymers to fight and kill drug-resistant bacteria. According to Science Alert, 25-year-old Shu Lam was the one who developed a star-shaped polymer that can fight and kill six various superbug strains without the need for antibiotics. Lam is a Ph.D. candidate at the University of Melbourne.
