Food wrappers themselves do not directly make people fat, but concerns are often raised about chemicals from some packaging materials entering food, especially when exposed to heat. The bigger issue is usually the type of processed food inside the wrappers rather than the wrapper alone.
Packaged snacks, sugary foods, and fast foods are often high in calories, unhealthy fats, and additives. Some studies have also discussed chemicals like BPA and their possible health effects. Honestly, overall eating habits matter much more than just worrying about wrappers, though safer packaging awareness is definitely increasing now.
