What You'll Learn
Plastic sandwich bags contain PFAS 'forever chemicals'
Plastic sandwich bags are an issue due to their negative impact on the environment and human health. They are made from polyethylene, a synthetic polymer derived from fossil fuels, and their production releases harmful greenhouse gases, contributing to climate change. Plastic bags can take over 1000 years to decompose, breaking down into microplastics that are ingested by marine life, leading to starvation and ecological disruption.
Moreover, plastic sandwich bags often end up in landfills, as recycling processes are complex and not widely accessible. The chemicals in these plastics can leach into food and water, causing health issues such as cancer, hormonal imbalances, and reproductive problems.
Most significantly, plastic sandwich bags have been found to contain PFAS (per- and polyfluoroalkyl substances), also known as "forever chemicals." PFAS are added to packaging to prevent food from sticking and as a grease-proofing agent. Mamavation, an EPA-certified laboratory, tested 11 popular plastic sandwich bags, and 81% showed indications of PFAS. The detected levels ranged from 9 to 34 parts per million (ppm), while the FDA allows up to 2,000 ppm for certain types of PFAS in food-contact plastic.
PFAS are detrimental to human health and are linked to cancer, liver problems, thyroid issues, birth defects, kidney disease, and decreased immunity. They are persistent and toxic, affecting hormonal health and posing risks to vulnerable areas like breast tissue and the lymphatic system. The EPA has found that virtually no level of exposure to certain PFAS in drinking water is safe, and independent research reveals widespread exposure through food.
To reduce PFAS exposure, consumers are encouraged to opt for reusable or biodegradable alternatives to plastic sandwich bags. While plastic bags might be slightly cheaper, the cost to the environment and human health is significant.

Plastic sandwich bags are bad for the environment
Plastic sandwich bags are detrimental to the environment. Firstly, they are made from polyethylene, a synthetic polymer derived from fossil fuels such as crude oil, natural gas, or coal tar. These non-renewable resources undergo chemical processes to become plastic, releasing harmful greenhouse gases that contribute to climate change. Plastic's environmental impact extends beyond its production; it persists in the environment for over 1000 years, breaking down into microplastics that are ingested by marine life, leading to starvation as their stomachs fill without providing nutrients. This plastic pollution also affects human health, with chemicals like PFAS (per- and polyfluoroalkyl substances) leaching into our food and water. PFAS are used to prevent sticking and as grease-proofing agents, but they are toxic and persistent, impacting hormonal health and leading to serious issues like cancer, liver damage, and a compromised immune system.
PFAS "forever chemicals" are pervasive, found in 81% of popular plastic sandwich bags tested, including brands like Boulder, Complete Home, and Target. While Ziploc and Debbie Meyer bags did not show PFAS markers, the presence of these chemicals in most bags highlights the urgency of switching to sustainable alternatives. Plastic sandwich bags are often cheaper than their eco-friendly counterparts, but their environmental and health costs are significant. Consumers are increasingly seeking sustainable options, and businesses can tap into this market by offering custom paper sandwich bags or reusable solutions like Bee's Wrap.
The issue of plastic waste is not limited to sandwich bags, with at least 14 million metric tons of plastic ending up in our oceans annually. Plastic pollution has devastating consequences for marine life and humans alike, and reducing plastic usage is crucial. While recycling is an option for plastic sandwich bags, the process is complex, and most recycling facilities are not equipped to handle them. Even when accepted, the bags must be clean and dry, which is often overlooked, leading to landfill disposal.
The negative environmental impact of plastic sandwich bags is undeniable, and the presence of toxic PFAS chemicals further exacerbates their harm. To protect our planet and our health, it is essential to transition to sustainable alternatives. By choosing reusable or biodegradable options, we can reduce plastic waste, minimize the release of greenhouse gases, and safeguard ourselves from the detrimental effects of PFAS contamination.

Plastic sandwich bags are harmful to humans
The chemicals used in the production of plastic sandwich bags, such as polyethylene, are of particular concern. These chemicals can leach into food and water, causing potential health issues. Studies have linked these chemicals to serious health problems, including cancer, hormonal imbalances, and reproductive difficulties. The presence of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals," in plastic sandwich bags further exacerbates the problem. PFAS are added to packaging to prevent sticking and as a grease-proofing agent. However, they are highly persistent and toxic, with potential negative impacts on hormonal health.
The manufacturing and disposal of plastic sandwich bags also contribute to environmental harm. The production of polyethylene, the main component of plastic bags, involves the use of non-renewable resources such as crude oil, natural gas, or coal tar, leading to the release of harmful greenhouse gases and contributing to climate change. Additionally, the recycling process for plastic sandwich bags is complex, and not all recycling facilities are equipped to handle them, resulting in a high likelihood of these bags ending up in landfills or the ocean.
The health risks associated with PFAS exposure are significant. PFAS have been detected in the blood of a vast majority of Americans, indicating widespread exposure. The potential health consequences of PFAS include liver damage, a weakened immune system, and certain types of cancer. The exact health effects of PFAS are still being studied, but the available evidence suggests that there may be no safe level of exposure to these "forever chemicals."
To reduce the harmful impacts of plastic sandwich bags, individuals can switch to reusable or biodegradable alternatives, such as paper sandwich bags, glass containers, or steel and cast-iron cookware. While recycling plastic sandwich bags is an option, it is important to note that they must be clean and dry, and even then, not all recycling centers can process them. Overall, the negative consequences of plastic sandwich bags on human health and the environment highlight the importance of transitioning to more sustainable alternatives.

Plastic sandwich bags are hard to recycle
Secondly, the recycling process for plastic sandwich bags is intricate, and not all recycling facilities are equipped to handle them. Even if a local recycling center accepts these bags, they must be meticulously cleaned and dried before disposal, which many users often neglect, ultimately leading to landfill accumulation.
Additionally, the presence of PFAS (per- and polyfluoroalkyl substances) in plastic sandwich bags further complicates recycling. PFAS are added to packaging to prevent food from sticking and as a grease-proofing agent. However, these toxic "forever chemicals" can migrate into food and liquids at high levels. While the FDA allows up to 2,000 parts per million (ppm) of PFAS in food-contact plastic, studies have found levels ranging from 9 to 34 ppm in sandwich bags. The EPA has also concluded that there is virtually no safe level of exposure to certain PFAS in drinking water.
The inability to recycle plastic sandwich bags contributes to the growing problem of plastic waste. Annually, approximately 14 million metric tons of plastic end up in our oceans, breaking down into smaller pieces that marine animals mistake for food. This ingestion leads to starvation as the plastic fills their stomachs without providing any nutrients.
To address this issue, individuals can switch to reusable or biodegradable alternatives, such as Custom Paper Sandwich bags, reducing their environmental impact and minimizing the challenges associated with recycling plastic sandwich bags.
