What is Food Grade Silicone Sealant?

What is Food Grade Silicone Sealant?

Have you ever encountered the term ‘food grade’ and wondered what it meant? Is it edible? No! Then, does it mean it’s safe enough to be near edible items? Absolutely. Food grade silicone sealant is specifically formulated to be safe for use in contact with food and beverages. They’re designed to meet strict regulatory standards and requirements for applications where there is a possibility of incidental contact with food, such as in food processing, packaging, and kitchen environments.

These silicone sealants are made from high-quality silicone materials that are non-toxic and do not contain any harmful substances that could leach into food. They’re free from chemicals like lead, PVC, phthalates, and other hazardous compounds, ensuring they do not contaminate food or compromise its safety. These sealants are characterized by their excellent temperature resistance, flexibility, and waterproof properties, making them ideal for use in environments with exposure to moisture, heat, and various cleaning agents.

So, are all silicone sealants food-grade?

No, not all silicone sealants are food-grade. As introduced above, food-grade sealants are non-toxic and free from harmful substances, ensuring food safety. Whereas, standard silicone sealants may not be suitable for food-related use, as they often contain additives or chemicals that pose contamination risks.

To avoid the risk of using non-food grade sealants where they’re not suited and jeopardize your and your family's health, you must identify the minute difference between them.

How do you identify if a silicone sealant is food-grade?

It’s pretty simple, in order to identify food-grade sealants, check product labels for ‘food grade’ or ‘safe for food contact.’

Usually, you’d find it on the sides or the neck of the packaging. Also, ensure that your chosen indoor silicone sealant complies with food safety regulations like FDA guidelines.

Note- In environments with potential food contact, always use designated food-grade silicone sealants to maintain food safety and consumer confidence. Don't compromise on quality and safety when it comes to food applications.
