Lab tests

What the silicone is tested to.

Name: GNSeal reusable silicone cover
Brand: GNSeal

A GNSeal cover stays on the pan, over the food, from the freezer to the oven. These are the standards its silicone is tested to, what each one checks and, just as plainly, what the tests do not cover.

Material

Silicone

The food-grade silicone the covers are moulded from.

Tested by

SGS

A third-party laboratory.

The standards

What each test checks.

Scope

What the reports cover.

SGS tested the food-grade silicone the covers are moulded from. These are material tests: they apply to the silicone itself — not to GNSeal as a company, and not to an individual finished cover.

That is why we say the silicone is tested to these standards, and claim no more than the reports show.
