The Silivac Solution
Delivering reliable sous vide results without plastic.
Vacuum Seals
Includes our handheld pump to easily remove air and keep food fully submerged during cooking.
Ultra-Thin
Thin enough for efficient heat transfer, responsive temperature control, and precise results.
Patented Double Seal
The top seal secures the bag above the pump valve, while the bottom seal maintains the vacuum.
Platinum-Grade Silicone
Independently tested by SGS laboratories to meet FDA and German LFGB food-contact safety standards.
We believe the tools that touch your food should be made with the same care as the food itself.
How It Works
-
Add Your Food
-
Close Top Seal
-
Remove Air & Double Seal
-
Submerge & Cook
Submersion Without Compromise
Confidence that your cook will stay fully submerged + peace of mind that nothing unwanted touches your food.
Thinner Bags, Faster Heat Transfer
At 0.4mm, Silivac is two times thinner than other silicone bags. Heat reaches your food faster for more even, more precise results.
Easy to Clean
45° angled corners mean no trapped food. Flip it inside out, hand wash or toss it in the dishwasher.
We Love Sous Vide. We Don't Love Plastic.
Why Silicone is Safer
Silivac believes cooking tools should support both performance and peace-of- mind.
-
Heat Safe
Silivac’s platinum-cured silicone is heat-stable and non-reactive, independently tested to remain stable from -40°F to 450°F.
Heat and long cooking times can increase the migration of small compounds from plastic into food, even in bags designed for sous vide.
-
No Bad Stuff
Because our platinum-cured silicone is a single, pure material, it doesn't rely on the "hidden" chemical softeners found in many plastics.
Because many plastics rely on stabilizers and softeners, even BPA-free bags can allow small amounts of additives to migrate into food when heated.
-
Sustainable
Silivac can be used hundreds of times without losing structural integrity or shedding microplastics, even after repeated high-heat cycles.
Plastic vacuum bags are typically designed for single use and discarded after cooking, creating plastic waste.
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.

"I tried every silicone bag on the market and they all had the same problem: too thick, and they floated. Silivac is genius, and the cute designs make me smile every time I cook."

"Their silicone bags are easy to use, cook food evenly, and most importantly, allow me to sous vide safely without plastic. These bags are a game changer!"

"Before Silivac, I tried nearly every silicone bag on the market for sous vide. They were all too thick and floated in the water. So when I found Silivac, I could appreciate how genius this product is."

"I love cooking sous vide but hated how many plastic bags it required. Silivac bags are a fantastic alternative. They're easy to clean in the dishwasher, store compactly when rolled up, and perform perfectly for sous vide."

How We Got Here
We love sous vide cooking for its ability to set it, leave it, and consistently get good results. But one part never quite sat right with us: cooking food for hours in plastic.
As we learned more about microplastics and long-term exposure, we started paying closer attention to the materials in our kitchen. We tried silicone bags, but most are designed for storage, not sous vide. Air gets trapped, bags float, and nothing works the way it should.
For us, it's not just about the food. It's about who we're feeding. So we built something better: an ultra-thin, platinum-grade silicone pouch paired with a small vacuum pump that actually holds a seal when submerged. No workarounds.
Our goal is to give you a safer way to sous vide, so you can feel good about the food you eat.

Frequently Asked Questions
Yes. Silivac is independently tested by SGS laboratories to withstand the long cooking times and temperatures required for sous vide. The platinum-cured silicone remains stable under heat and is safe for use from -40°F to 450°F.
Silivac is designed for use in a water bath or freezer, not for vacuum storage at room temperature. Silicone is naturally air-permeable, which means small amounts of air can pass through the material over time. As a result, the vacuum seal will gradually loosen if stored at room temperature.
Two patterned silicone bags (quart size) and one rechargeable vacuum pump. Everything you need to start cooking.
It takes about 30 seconds once you’ve done it once. Close the top seal, turn on the pump to remove air, and then close the bottom seal. We include a quick-start guide with every bundle.
Cleaning your Silivac pouch is easy, and there are a couple of ways to do it.
Step 1: Flip the pouch inside out and wipe away any food residue.
Step 2: (Choose one cleaning method):
Hand wash: Flip the pouch back, fill it with warm water and a few drops of dish soap, seal it, and gently shake. Rinse thoroughly.
Dishwasher: Place the pouch in the dishwasher, ensuring it is upright so water can enter the bag.
Step 3: (Drying):Place the pouch over a rack, container, or bottle to air dry. Please ensure the pouch is fully dry before storing.
Silivac is rated for over 1,000 uses. Platinum-grade silicone is extremely durable across extreme temperatures.
