Cling Film: The Invisible Health Risks in Your Kitchen
Table of Contents
An authoritative warning comes from France: the use of cling film for food can result in invisible but concrete risks for health. The alarm is raised by Christophe Mercier-Thellier, renowned microbiologist, who invites us to abandon this common tool in kitchens due to the presence of perhaps perilous chemicals.
According to the expert,some components of the obvious film,such as phthalates and PVC,could act as endocrine disruptors,altering the normal hormonal balance of the body.
What does cling film really contain?
November 20, 2025 marks a turning point in the debate on safety of materials in contact with food. Many transparent films commonly on the market are made in polyvinyl chloride (PVC), a plastic material made flexible by the addition of chemical additives.
Phthalates and other plasticizers make the film easier to handle, but can migrate to food with time.
Even small quantities can have effects on the endocrine system.
The daily and widespread use of cling film increases the risk of chemical contamination.
Be careful with fatty foods: the risk increases
The danger grows when the film comes into contact with fatty foods such as butter, cured meats and cheeses. Fats facilitate dissolution and transfer of chemical compounds in food.
Potential effects:
- Accumulation in the human body
- Possible hormonal and reproductive alterations
- Increased risk in sensitive individuals,such as children and pregnant women
Despite the limits imposed by the EFSA (European Food Safety Authority),several studies indicate that domestic use remains a significant source of exposure.
The expert’s appeal: “Enough with cling film”
During a recent television broadcast in France, Mercier-Thellier openly stated that the transparent film should be eliminated fully. A statement that contrasts with the common perception of a “harmless” tool if used occasionally.
“It’s time to choose chemical-free and safer alternatives for your health.”
The debate is open and more and more consumers are starting to wonder what are the truly safe alternatives.
