By KENNETH BRYANT and LESTER KANE | ESPN.COM This is the question that will come up as more plastic sealant companies come under scrutiny: Does it work?
The issue has been a constant topic for some plastic-sealing companies, as a new study by the University of California-Berkeley found that the majority of sealants tested failed to meet industry standards for protecting plastics.
In fact, the study found that of the 15 plastic sealants studied, 17 had reported failure rates of at least 50 percent.
That is far higher than the 20 percent failure rate that has been cited in previous studies.
The study was done by the UCLA Environmental Research Institute, which has done research into plastic safety for decades.
It examined the use of various plastic sealings for different applications.
The results, released this week by the organization, are surprising because they were based on a small sample of plastic-sensor products tested.
The authors concluded that some plastic sealing products are “not suitable for use for sealant applications,” and that some of them can actually damage plastic seals.
In the study, the authors said that the best way to make sure that a sealant is not damaging plastic seals is to “have a close look” at the product and then “use a small amount of a protective material that is a low-risk alternative.”
In the end, they said, the best sealant would be “to use the lowest-risk, low-cost alternative that will work for your application.”
That might sound like a cop-out.
The problem is that plastic-pandemic sealant has come under fire for being too expensive, and too complex for consumers to understand.
It has also come under attack for failing to protect plastics, with some scientists arguing that the process is “unethical” because the seals are supposed to be “unbreakable.”
The study, published in Environmental Science & Technology Letters, looked at 10 types of plastic sealors and found that about 60 percent failed to protect against contamination by the common bacteria E. coli O157:H7.
That rate is well below industry standards, according to the authors, who also found that only about 30 percent of the products tested were safe for people with certain medical conditions.
They also found no evidence that the plastic-coating process could be safely used on plastic bags or other plastic items, even though it has been shown to protect bags and other plastics from bacteria.
While there is little information available about how much of the sealant products are safe for consumers, the researchers did find that the “quality control process of the market” should “improve substantially.”
The report found that a single-use plastic seal on a bag is more likely to damage a plastic bag than a single use plastic seal for a plastic product.
The researchers said this should be a concern because a single application of a seal could damage hundreds or thousands of bags and products.
The researchers also found plastic-soaked or plastic-laced bags are more likely than other bags to damage plastic, which could lead to higher cost to consumers.
The scientists found that plastic bags made from polyvinyl chloride, a chemical commonly found in some plastic packaging, were more likely “to damage plastic than those made from a non-polymer plastic material.”
The researchers found that while the researchers analyzed the use data of each seal, it was not possible to measure how often the product was actually used for sealants.
That may not mean much for consumers who are unaware of the use information on the packaging.
In other words, we don’t know the true use rates of the plastic seal products, which may not be the most accurate way to determine how many seals are actually used.
What’s also worrisome is that consumers are not necessarily aware that they need to use a product to protect plastic from bacteria, because they have been told by retailers and manufacturers that it works.
“Many consumers do not know that a product may be unsafe for plastic,” the researchers wrote.
“Consumers who do know are not aware of how they can safely use a seal, or whether their use of a product could potentially harm plastics.”
This is not the first time that the issue has come up in the plastics industry.
In 2011, a Consumer Reports study found a failure rate of more than 50 percent of plastic plastic sealable products tested that were tested for bacterial contamination.
That study was published in the journal Consumer Reports.
