Silivac Technical Verification & Safety Standards

Silivac pouches are independently tested by SGS laboratories to verify compliance with recognized global food-contact standards. These test reports demonstrate Silivac silicone remains stable during the extended heating cycles used in sous vide cooking.

Understanding Our Certifications

German LFGB (Europe’s Strictest Standard)

The LFGB is significantly more stringent than the FDA. To pass, our silicone was subjected to a 24-hour soak at 100°C in both distilled water and acidic simulants.

  • The Result: The extractable components were so low they were categorized as "n.d." (Not Detected).

  • What it means: This proves Silivac pouches will not leach chemicals into your food, even in highly acidic environments like citrus or vinegar-based marinades.

U.S. FDA 21 CFR 177.2600

This U.S. regulation sets safety requirements for rubber articles intended for repeated use with food.

  • The Result: Our material showed a total extractive of only 0.323 mg/in².

  • What it means: This is nearly 60 times lower than the legal limit of 20 mg/in², confirming the material is exceptionally stable for repeated kitchen use.

 

 

Material Integrity

  • Platinum-Curing: Platinum-cured silicone is commonly used in medical and infant products because the curing process produces fewer residual byproducts, reducing the risk of “blooming” (white residue) or odors when heated.

  • Thermal Stability: Engineered to withstand sous vide temperatures without losing structural integrity or shedding microplastics.

  • Non-Reactive Surface: Silicone is chemically stable and does not react with fats or oils, helping preserve the natural flavor of your ingredients.
