Food grade rubber sheets, this seemingly ordinary material, play a crucial role in our daily lives. You may find it in kitchenware, catering equipment, and even baby products. But how much do you know about it? Today, let’s delve into this important material – the standards and characteristics of food grade rubber sheets.
Food grade rubber sheets are rubber products specifically designed for food contact. They are mainly made from natural rubber and processed through a series of complex procedures. These rubber sheets must meet the relevant national standards for food contact materials to ensure their safety and reliability.In simple terms, food grade rubber sheets are the guardians of the safety of the food we consume.

Let’s take a closer look at several key indicators of food grade rubber sheets.
First is the specific gravity. The specific gravity of food grade rubber sheets is usually between 1.4 g/cm³ and 1.8 g/cm³. This parameter determines the density of the rubber sheet, directly affecting its performance and durability.
Second is the tensile strength. High-quality food grade rubber sheets should have a tensile strength of 5 MPa to 10 MPa. This value reflects the material’s tensile resistance. A high tensile strength means the rubber sheet is less likely to break under stress and is more durable and reliable.
In addition, elongation is also a key indicator. The elongation of food grade rubber sheets should be between 250% and 400%. This data indicates the extent to which the rubber sheet can be stretched. A higher elongation ensures the material’s flexibility and elasticity, providing good adaptability in various application scenarios.
Finally, hardness. The hardness of food grade rubber sheets is usually between 50 Shore A and 80 Shore A. The hardness is moderate, neither too hard to cause cracking nor too soft to affect the usage effect.
In addition to the above physical parameters, the chemical properties of food grade rubber sheets are equally important. This material is non-toxic, odorless, and chemically stable. It does not react with any acids, bases, or salts at room temperature. These characteristics ensure that food grade rubber sheets can maintain stable performance in various complex environments, ensuring food safety.
Why do we need such strict standards for food grade rubber sheets?
The reason is simple. Food safety is related to everyone’s health. Any material that directly or indirectly contacts food must undergo strict testing and certification to ensure that it does not release harmful substances and does not affect the quality and safety of food. For this reason, food grade rubber sheets need to undergo multiple process inspections during production, from raw material selection to finished product delivery. Every link needs to be strictly controlled.
It is worth noting that food grade rubber sheets are not only used in household kitchenware but also widely applied in the food processing industry, medical equipment, and infant products, among other fields. Whether it’s the anti-slip pad on a cutting board, the protective layer on a food conveyor belt, or products like baby pacifiers and soothers, they all rely on the application of food grade rubber sheets. These applications fully demonstrate the importance of food grade rubber sheets in ensuring food safety.
