CR-39: An Unlikely Path for an Innovative Plastic Eyeglass Material (Part II)

In our last post, we traced the unlikely path of plastic resin compound CR-39 from a wartime aviation innovation to a promising material for a very different purpose: the production of eyeglasses.

This time, we’ll look at some of the technical challenges Dr. Robert Graham had to overcome before he was able to perfect the use of CR-39 for optical […]

CR-39: An Unlikely Path for an Innovative Plastic Eyeglass Material (Part I)

As described in earlier posts on this blog, the Second World War marked a major turning point for the development of the modern plastics industry. Shortages of important materials and manufactured products, including glass, steel, and rubber, among others, led entrepreneurs in the United States to develop new materials that could be produced cheaply and in large volumes and […]

The Past and Future of the Humble Drinking Straw

Straws have been in the news a lot lately. Although straws make up only a very small portion of plastic waste, they are a public symbol of the environmental impacts of the plastics industry. In this article, we’ll examine the history of straws and the benefits provided by using plastics to make straws. We’ll end by taking a look […]

Trends in Flexible Packaging

In 2018, one of the fastest areas of packaging growth was in the realm of flexible packaging. For those who are unfamiliar with the term, flexible packaging refers to packaging that (unsurprisingly) can easily change in shape. Compared to traditional hard-sided packaging products, flexible packaging requires significantly less material.

Typically, flexible packaging takes the form of a stand-up pouch, and […]

Ocean Clean Up Project Launches Plastic Clean Up Vessel

September 2018 was an exciting time for “Ocean Cleanup”, an ambitious project aiming to remove floating plastic from the Great Pacific Garbage Patch, an infamous gyre of floating plastic waste collected by currents in the East Pacific Ocean. The project aims to collect floating plastic materials by mimicking longshore currents that transport debris along natural shorelines.

After several years of […]

Will Self-Destructing Plastics Revolutionize Recycling?

In countless posts on this blog, we’ve extolled the benefits of plastics – they are strong, impermeable, mouldable, and, critically, long-lasting.

One of the greatest strengths of plastics materials is that they are stable for remarkably long periods of time – they don’t break down quickly when exposed to light, heat, or air. That’s a good thing in an era […]

Earl Tupper and the Container of the Future

The 1950s were heady times in the world of plastics technologies. Plastics were part of a new wave of futuristic technologies that were predicted to change the world. At a time when flying cars and personal robots seemed just around the corner, its no surprise that the atmosphere was right for the introduction of new, plastics-based conveniences to everyday […]

Could Two Natural Polymers Lead to a New Plastics Packaging Future?

The use of plastic films to protect food from spoilage has revolutionized the global food production system. As previously reported on this blog, the environmental impact of throwing food away when it has gone bad is often much greater than the impact of the plastics used to package the food. For example, one company reports findings that only 11% […]

Will Southeast Asia Recycle More in Response to China’s Import Ban?

As soon as China broke the news that it would no longer accept the world’s plastics waste for recycling, analysts suggested that countries in southeast Asia, such as Indonesia and Thailand, might ramp up imports as the price of plastics waste began to fall with falling demand. Perhaps, many thought, not much would need to change with the current […]

Despite Bans, Single Use Plastics Are Here to Stay in Some Industries

In recent years, the plastics industry has been impacted by a series of bans enacted by governments at all levels. This year, Seattle became the first American city to ban disposable straws and utensils. In Australia, of course, plastic bags have been banned in Western Australia and Queensland, and are no longer provided by some major stores, including Coles […]
