We have long known that plastic bags are a big problem, but they are also incredibly popular.
Plastic bags are made from polyethylene, a material which has been around for thousands of years.
When you get plastic into your body it can clog your pores, which can cause problems, such as heart disease and cancer.
But now scientists are beginning to understand how the materials work.
They are using the same principles of chemistry that work in the plastics we buy and drink to work out how they work in nature.
This makes a huge difference in the way we can tackle plastic pollution.
In the US, for example, the US Environmental Protection Agency is using a new type of polymer called polyethylenimine (PEI), which can bind with marine plastic to form a protective membrane that traps water and protects the body from the chemical.
The membrane can also act as a sealant to prevent water from entering the lungs.
But this is only part of the story.
It is possible to produce membranes that can form on other types of polymers as well.
For example, PEI can form a membrane on polyethylenes which are used to make PVC pipes, which make up most of the plastic used in the plastic bags we use to fill our plastic bags.
And PEI is also a very strong material that can withstand the extreme heat and pressure that polyethylens are subjected to.
In fact, a new research paper published in the journal Science Advances suggests that PEI may be as effective as polyethyleneglycol (PEG) as a membrane when it comes to protecting against marine plastic pollution, says Dr Jocelyn Hickey, a researcher at the University of Queensland.
“The membranes we’ve shown to be effective are made of two parts.
One is a protein and one is a lipid, and they act as membranes that bind with the marine plastic,” Dr Hickey says.
“So the protein has the ability to bind with it and then the lipid is able to bind to it, which makes it even more resilient.”
So how do they work?
Researchers have been studying the chemistry of polyethylenoic acid (PEA), a common polymer used in polycarbonate plastics, for decades, so it is no surprise that it is now one of the most common ingredients in plastics.
“Polyethylene is used in plastics, and it’s a relatively common component in our environment,” Dr Ian Walker, a plastic scientist at the Australian National University, told the ABC.
“But it’s also been known to be a chemical, and we’ve found a number of molecules that have the ability and properties to bind together with it, and so it’s actually pretty simple to work with.”
So far, PEAs have only been used in small amounts to treat wounds in the body.
But Dr Walker says that using them to treat marine plastic will have significant health benefits.
“These are really small molecules that are actually very active in the environment,” he says.
And because they are able to do this, they are very efficient at preventing the formation of polychlorinated biphenyls (PCBs) – chemicals that are known to pollute the environment.
These are chemicals that have been linked to cancer and other health problems.
“They are incredibly important to plastics because they act like the ‘residue’ of these chemicals, and that’s why we’re going to need to be really careful when we use them,” Dr Walker adds.
The researchers believe PEAs can be used in a number other applications, including in medical applications.
Dr Hicky is particularly excited about the possibility of using PEAs as a treatment for marine plastic.
“We’re actually working on it now,” she says.
It may be years before PEAs will be able to replace plastic bags, but there is a good chance that they could eventually be used as a way to reduce pollution.
“It’s possible that we’ll be able take plastic bags off the road and put them into these membranes,” Dr Mandy Geddes, a plastics expert at the Queensland University of Technology, says.
She says the membrane could be applied to make products that filter out plastic pollution such as drinking straws, but she also cautions that PEAs should be used sparingly.
“I would be worried about people eating them, as they can be very irritating,” she adds.
The paper, published in Science Advings, also suggests that some PEAs might be used to treat heart disease, cancer, and other conditions that are linked to the plastic we use in our everyday life. “
Even though we know it can protect the body, it is still a risk.”

Dr Walker agrees that PEA could be used safely, but he says there are still some important safety issues that need to
