FDA-approved, food-grade silicone rubber products are commonly used in applications where food or consumables are present, such as food processing, beverage bottling and manufacturing, dairy production, meat packing, and pharmaceutical applications. FDA silicone rubber products are also found within most food packaging equipment, such as table-top packaging machinery. All FDA-approved products are handled and packaged in a Class 100 cleanroom environment and subjected to rigorous testing to meet the demands of challenging food and beverage applications.

This material selection guide will provide an overview of FDA standards for food-grade materials and some of the typical applications for each material, helping you to identify the ideal food-grade gasket or seal for your application. 

Finding the ideal food-grade gasket or seal material can be vital to an application. It requires a basic understanding of requirements for FDA approval, along with the material properties that best suit the specifics of your use case. Food-grade materials must be hypoallergenic, non-toxic, flexible, tasteless, odorless. They should also prohibit bacterial growth and have a wide operating temperature range.

Silicones have many desirable properties but can cost more than other polymers. That’s why some engineers and product designers avoid them. At the same time, newer materials such as thermoplastic elastomers are interesting but even more expensive.For example,using it to make tight&leak proof seal is the best choose. 

Chaojie manufactures silicone air tight & leak proof seals for all types of plastic containers & steel tiff ins.
