Chemical Composition: Silicone is generally considered to be safer for food contact compared to many types of plastic. Silicone is a synthetic rubber made from silicon, oxygen, carbon, and hydrogen. It does not contain harmful chemicals such as BPA (bisphenol A), phthalates, or PVC (polyvinyl chloride), which are commonly found in some plastics and are known to leach into food.
Durability and Stability: Silicone tends to be more durable and heat-resistant than many types of plastic, making it suitable for a wider range of temperatures, including freezing and high-heat cooking. It is less likely to degrade or leach chemicals when exposed to heat, sunlight, or certain types of food compared to some plastics, which can release toxins when exposed to heat or UV radiation.
Non-Porous and Easy to Clean: Silicone is non-porous, meaning it does not absorb flavors or odors from food and is less likely to harbor bacteria compared to some plastics, which can develop scratches and cracks over time, providing a breeding ground for bacteria.
Environmental Impact: Silicone is generally considered more environmentally friendly than many types of plastic because it is more durable and can be recycled. However, it's worth noting that silicone is not biodegradable and may still contribute to environmental pollution if not disposed of properly.
In summary, while both silicone and certain types of plastic can be used safely for food contact, silicone is often considered a safer and more durable option due to its lack of harmful chemicals, resistance to heat and degradation, non-porous nature, and ease of cleaning. However, it's essential to choose high-quality silicone products from reputable manufacturers to ensure safety and avoid any potential risks.
