Aluminum containers in US, Europe may be more durable than plastic
Posted On July 4, 2021
A new report from the US Department of Agriculture (USDA) has found that aluminum containers used for domestic use may be the most durable of all plastics used for food containers.
The study, published in the journal Food and Chemical Toxicology, analyzed 1,844 of the world’s largest aluminum containers from 12 countries, which are used for a range of purposes from cleaning to storing and transporting vegetables, fruits, milk, meats, fish, eggs, and dairy products.
While some of the plastic containers had been used for many years, there were some that were newer.
The analysis found that of the containers tested, 70% were made of plastic and 40% were plastic containers with a coating of aluminum.
This is a much higher percentage of aluminum containers than most other plastics used by the food industry, the study found.
According to the study, aluminum containers are generally made of either an aluminum-based plastic (30% to 40%) or polyethylene (50% to 60%).
However, some of these are made of a metal-based polymer (15% to 20%), which is not as common.
The majority of the aluminum containers tested were made with a combination of plastic (80%) and aluminum (15%).
It’s important to note that the study was done on plastic containers, so it’s possible that some of them may not be the best choice for your kitchen, the authors write.
“The results indicate that while aluminum containers may be less durable than most of the other plastics that food companies use, there is a very large amount of variation in aluminum consumption,” they write.
The findings come at a time when aluminum containers have become increasingly popular as a way to store food and other items.
to the American Association of Analgesic Chemists, aluminum is used in the manufacture of products such as dishwashers, dishwasheets, and dishwasher foam, among others.
The chemical, which is a byproduct of the reaction of aluminum with water, has been used to coat food and detergents for decades.
“In addition, the use of aluminum has resulted in increased awareness among consumers and the use for food packaging and containers,” the AACC states on its website.
The aluminum-coated aluminum containers that the researchers tested may also be less prone to cracking and breaking over time.
In fact, some researchers have noted that a number of the food-related food containers in the study were cracked and damaged over time due to the aluminum coating, according to the AP.
But these containers were all manufactured using the same technology, and the study authors note that they did not measure the durability of the individual pieces of aluminum used for each individual container.
The researchers found that the aluminum container with the most aluminum content was manufactured using polyethylenimine (PEI), which has been widely used for over 50 years.
It’s known to have strong anti-corrosion properties and is known to help reduce bacteria and yeast growth in foods, according the AACS.
The report’s authors recommend that manufacturers of food containers and food packaging materials be aware of the risk associated with aluminum, noting that “the increased prevalence of aluminum-containing foods and containers is an emerging public health concern.”
Aluminum is also used in many other food products, including salad dressing, bread, cereal, cookies, and chocolate.
“We are concerned that the increased use of the polymer and polyethylenes in food packaging may result in aluminum toxicity for consumers and that these materials may also have adverse health consequences for consumers, including increased risk of cancer,” the researchers write.
