Experts note that migration is generally more likely when cling film comes into contact with fatty foods, such as butter, cheese, processed meats, and other high-fat products. Fat can increase the transfer of certain chemical compounds from plastic into food.
Potential concerns discussed in scientific research include:
- Increased overall exposure to certain plasticizers.
- Possible effects on the endocrine system with long-term exposure.
- Greater caution for vulnerable groups, including children and pregnant women.
The European Food Safety Authority (EFSA) regulates the use of food contact materials and establishes safety limits for substances that may migrate into food. However, researchers continue to study long-term exposure from everyday household products.
The Expert’s Recommendation
During a recent television appearance in France, Christophe Mercier-Thellier recommended reducing or avoiding the use of traditional PVC cling film whenever practical.
He encouraged consumers to choose food storage materials that do not rely on plasticizers, particularly for fatty foods or foods stored for extended periods.
As awareness grows, many consumers are exploring alternative storage methods that may reduce unnecessary exposure to certain chemicals.
