We use products made from plastic every day. However, did you ever think about the material and how it’s produced? Did you ever pay attention to the research that’s underway in the plastics industry? If not, this article is for you.
Here, we highlight 3 innovations currently happening in the plastics industry:
1. Fully recyclable toothpaste tubes
By introducing a recyclable toothpaste tube, Colgate is doing their part to contribute to the green movement.
Often, it’s not possible to recycle traditional toothpaste tubes because at least some part of the tube has a thin layer of aluminum too.
However, this tube uses HDPE (high-density polyethylene), which is a substance typically used in the production of plastic bottles. To get the right malleability required for squeezable toothpaste tubes, the team at Colgate had to test a number of composite and layering options until they arrived at the desired outcome.
2. Biodegradable bioplastics for food packaging
Scientists at the Kaunas University of Technology in Lithuania have devised a biodegradable plastic that can decompose in a couple of years with a compost bin.
Once it’s made public, the applications of this material will include replacements for plastic storage bags and shopping bags, single-use packaging for goods, etc.
However, scientists had to face a lot of challenges. For example, they were working with cellulose, which is required to be made semi-transparent or transparent to match current plastic packaging products. Unfortunately, cellulose burns upon being exposed to heat.
But thankfully, scientists were able to find the right composites required to transform the cellulose into fluid plastic, creating a nontoxic, transparent package safe for foodstuffs.
3. Bacteria that can break down plastics
In 2005, a bacterium referred to as Ideonella sakaiensis was discovered. Now, it has been shown to consume polyethylene terephthalate (PET) film with a thickness of around 0.2 millimeters in a month.
Since scientists previously believed that PET was nonbiodegradable due to its origin in petroleum, this discovery may have a major impact on the future of plastic disposal and recycling.
Currently, scientists are conducting studies to find out the conditions required for their enzymes to properly break down the materials.
PTMS has good cost-effective, efficient, and reliable in the production of custom injection molding
The injection machines of PTMS can run every type of resin from high temperature to filled materials, a commodity to engineered grades. They only work with high-quality plastic resin suppliers within the industry.
