Silivac makes the first silicone pouches engineered specifically for sous vide cooking, replacing single-use plastic bags with a reusable, platinum-grade silicone alternative. The patented vacuum-seal system includes a handheld pump and ultra-thin 0.4mm walls that stay submerged without weights, delivering reliable heat transfer while meeting FDA and German LFGB food-safety standards.

Problem
Traditional sous vide cooking relies on single-use plastic vacuum bags, which can leach chemical additives and microplastics into food during prolonged heating. Existing silicone bag alternatives are typically designed for storage, not cooking—they are too thick, trap air, float in the water bath, and fail to create a proper vacuum seal, forcing home cooks to use workarounds like magnets and weights.
Solution
Silivac provides a reusable, platinum-grade silicone pouch specifically engineered for sous vide cooking, paired with a rechargeable handheld vacuum pump. The bags feature a patented double-seal system: the top seal secures the bag above the pump valve, while the bottom seal maintains the vacuum so food stays fully submerged without clips or magnets. At just 0.4mm thick, Silivac is two times thinner than other silicone bags, enabling faster and more even heat transfer for precise results. The pouches are independently tested by SGS laboratories, showing extractable components below detection limits under the German LFGB standard and nearly 60 times lower than the U.S. FDA limit, confirming they are safe for repeated high-heat use.
Target Audience
Primary customers are home cooks and sous vide enthusiasts who want a safer, reusable alternative to plastic vacuum bags and are frustrated by the performance limitations of existing silicone bags on the market.
