Phthalates are a group of chemicals used to make plastics more flexible and harder to break. They are often called plasticizers. Some phthalates are used as solvents (dissolving agents) for other materials. They are used in hundreds of products, such as vinyl flooring, adhesives, detergents, lubricating oils, automotive plastics, plastic clothes (raincoats), and personal-care products (soaps, shampoos, hair sprays, and nail polishes).
Phthalates are used widely in polyvinyl chloride plastics, which are used to make products such as plastic packaging film and sheets, garden hoses, inflatable toys, blood-storage containers, medical tubing, and some children’s toys.
How People Are Exposed to Phthalates
People are exposed to phthalates by eating and drinking foods that have been in contact with containers and products containing phthalates. To a lesser extent exposure can occur from breathing in air that contains phthalate vapors or dust contaminated with phthalate particles. Young children may have a greater risk of being exposed to phthalate particles in dust than adults because of their hand-to-mouth behaviors. Once phthalates enter a person’s body, they are converted into breakdown products (metabolites) that pass out quickly in urine. ...
Dining out more at restaurants, cafeterias and fast-food outlets may boost total levels of potentially health-harming chemicals called phthalates in the body, according to a study out today. Phthalates, a group of chemicals used in food packaging and processing materials, are known to disrupt hormones in humans and are linked to a long list of health problems.
The study is the first to compare phthalate exposures in people who reported dining out to those more likely to enjoy home-cooked meals. People who reported consuming more restaurant, fast food and cafeteria meals had phthalate levels that were nearly 35 percent higher than people who reported eating food mostly purchased at the grocery store, according to the study. ...
In the past few years, researchers have linked phthalates to asthma, attention-deficit hyperactivity disorder, breast cancer, obesity and type II diabetes, low IQ, neurodevelopmental issues, behavioral issues, autism spectrum disorders, altered reproductive development and male fertility issues. ...
Phthalate exposures can produce a variety of adverse effects in laboratory animals; especially on the development of the male reproductive system, and therefore there are implications for human health. Animal data on the cumulative effect of mixtures of several phthalates showed an increase in the reproductive effects in the organism exposed. Phthalates are produced in high volume and they are used in numerous industrial and consumer products. Phthalates appear in biomonitoring surveys, such as NHANES, that provide evidence of widespread human exposure. Phthalates are also found in the environment and wildlife species. EPA is concerned with phthalates based on toxicity, particularly to the development of the male reproductive system, prevalence in the environment, widespread use and human exposure and recent work focusing on the potential cumulative effect of mixtures of phthalates. ...
That’s why, in January, she launched Stasher, a line of sandwich bags made entirely of silicone, a natural substance made of sand, rock, and oxygen. The silicone bags work just like regular plastic bags – they’re pinch-press and air-tight – but unlike Ziploc bags, they’re completely biodegradable. They’re also petroleum-free and contain no PVC, latex, or phthalates.
The bags are easy to clean and can be reused for at least 3 years and can be frozen, which means they’re less likely to wind up in landfills, or worse, lying around on the side of the highway.
The bags’ non-porous surface inhibits bacterial growth. A 3-D pocket allows for extra storage, and a see-through window allows you to see what is inside the bag. You can even label them with dry-erase markers. ...

I think we're killing ourselves slowly, without Russia ever lifting a finger.
PS - you did see there's a writing contest up, didn't you?
if we are/were having issues with our oil supply, you would think that discontinuing the use of plastic in packaging and areas that we don't actually need to use it for Would be one of the top priorities.
What are the characteristics of atmospheric fibrous microplastics?
After chemical characterization, it appeared that 29% of the fibers evaluated in TAF are plastic, with the majority constituting cellulosic or natural origin [5]. The length distribution of fibers collected larger than 50 μm was assessed. On measuring fiber length, smaller size classes [200–400 μm] and [400–600 μm] were predominant whilst fibers in the larger size ranges were rare. Few fibers measuring between 50 μm (observation limit) and 200 μm in length have been detected. The diameter of the fibers varied mainly between 7 and 15 μm.
What are the characteristics of fibrous microplastics in indoor environments?
According to chemical characterization, 67% of indoor fibers were made of natural material, primarily cellulosic, while the remaining 33% of fibers contained petrochemicals with polypropylene being predominant [6]. A similar size distribution was determined for indoor air, outdoor air and TAF with slight differences. These differences between compartments lie in the size of the longest observed fibers: while fibers in the range of 4,650–4,850 µm can be found in dust fall, no fiber longer than 3,250 µm is observed in indoor air, which is almost double the size of the longest fibers in outdoor air (1,650 µm). Larger fibers are observed in dust fall because they settle more rapidly and accumulate on the floor. While fibers under 50 μm were not counted due to the observation lower limit, the size distribution pattern suggests that much smaller fibers might be present.

Are airborne fibrous microplastics breathable?
The likelihood that airborne fibrous MPs enter our respiratory system will be dependent upon size. First, it is important to discriminate between the terms inhalable and respirable. Particles and fibers able to enter the nose and mouth and deposit in the upper airway are inhalable, whilst those able to reach and deposit in the deep lung are respirable. Deposition in the airway is a function of aerodynamic diameter and within the respiratory zone, deposition falls off above 5 μm diameter [11]. ...
a Salt Lake City-based entrepreneur and her partner have developed a proprietary process that turns recycled waste plastic into crude oil that is so advanced that it can be made into gasoline, kerosene and diesel easier than the oil that comes straight out of the ground.
The company’s commercial-scale facility was moved to Salt Lake City in 2012 and now has enough capacity to convert 20,000 pounds of non-recycled plastic to 60 barrels of oil per day — all with zero emissions.
About 70 to 80 percent comes out as oil, while about 10 to 20 percent comes out as natural gas that is recycled to keep the system heated so you don’t use any additional outside energy,” she said. The remaining small percentage is “char” waste — dirt and residue on the plastic. ...

Even milk is usually in plastic containers these days. Just because you buy milk in a glass bottle does not mean it is safer, the organic certification only means that nonorganic stuff on the land has not been added in the last five years. But some farmers are more picky than the minimum, there is some good organic out there.

This is why I like living outside the city. Friend of mine from church is an organic farmer with a few cows. Milk goes from the cow to the stainless steel milking pail to glass jars to the refrigerator. No phthalates, no packaging, etc. I trade him homebrew for milk; works out pretty darn well.
And the cream you can skim off the top makes a heck of a pumpkin pie.
And you would be positively right..we will never (not in our lifetimes) get away from plastic.

Thursday, March 22, 2018 On Wednesday, Washington Gov. Jay Inslee signed the first state law to ban toxic fluorinated chemicals in food packaging, such as microwave popcorn bags, pizza boxes and fast-food wrappers. The ban – conditioned on the state identifying a safer alternative – is a major defeat for the chemical and packaging industries, which have quashed similar proposed bans in other states.
For decades, chemical companies covered up the mounting evidence that PFAS chemicals were harmful to human health and the environment. Under pressure from the EPA, some PFASs were phased out, but the replacement chemicals, including those used in food packaging, are very similar in structure and may be no safer. A recent analysis by the Environmental Defense Fund shows the FDA has rubber-stamped several dozens of PFAS chemicals for use in food packaging.

a reply to: mysterioustranger,
Makes it hard to reduce waste if you can't use them more than a few times. Recycling hubs aren't readily available in rural areas either. No pick up available and you have to drive quite a ways to drop off the recyclables yourself. But also just everything you buy has phthalates in it. Anything made with plastic. From TV's to cell phones to baby toys...if there's plastic in it the chemicals to make plastic more flexible is in it as well. And those chemicals could be causing health issues.

Glass! Yes! I've been looking into silicone products lately (haven't completed all the research though). They are made from sand, rock, and oxygen. So far I haven't found anything bad about them health and environment wise. Fairly new and costly though.

They cost around $10-13 dollars each (quite steep) but, they last for over 3000 uses and can be used in the freezer, microwave, are dish washer safe and are biodegradable. I don't know why we are not switching over to this stuff. As you said, sand is not going to run out anytime soon.
At least we are looking for and coming up with alternate solutions to the plastic debacle. There are a couple companies that offer these bags now...it's a start.
Thanks for the responses..
