Kirkland Vacuum Sealing Bags: How to Use & Best Practices

Kirkland Signature vacuum sealing bags are a reliable, cost-effective way to preserve food longer, prevent freezer burn, and streamline meal prep. These bags work with most standard vacuum sealers and are designed to create an airtight seal that locks in freshness. Whether you’re portioning meat, storing leftovers, or marinating sous-vide, this guide walks you through the best methods for getting a perfect seal every time.

Ingredients

Kirkland Signature vacuum sealing bags (any size, e.g., 8″ x 12″ or 11″ x 16″)
Food to be sealed (e.g., raw meat, vegetables, dry goods, or leftovers)
Paper towels (for drying food surfaces)
Optional: vacuum sealer machine (compatible with textured bags)

Instructions

Prepare your food: If sealing raw meat, pat it dry with paper towels to remove excess moisture. For liquids like soups or stews, freeze them in a silicone mold or ice cube tray first until solid (about 2 hours) to prevent liquid from being sucked into the machine.
Cut the bag to size: Cut a piece of the roll long enough to hold your food, leaving at least 3 inches (7.5 cm) of extra bag material on the open end for sealing. Remember that one end is already sealed on the pre-made bags; if using a roll, seal one end first.
Place food inside: Put the food into the bag, leaving the open end clean and dry. Wipe any moisture or crumbs from the interior of the bag near the open edge—this ensures a strong seal.
Position the bag in the sealer: Place the open end of the bag into the vacuum sealer channel, ensuring it lies flat and the textured side faces the vacuum nozzle (if your machine requires orientation). Close the lid.
Vacuum and seal: Select the “Vacuum & Seal” function on your machine. The sealer will remove air and then heat-seal the bag. Wait for the indicator light to signal completion before opening the lid.
Check the seal: After sealing, inspect the bag to ensure the seal is straight and intact. Press gently on the bag—if you feel air escaping, re-seal the bag using the “Seal Only” function, placing the seal line just below the previous one.
Label and store: Write the contents and date on the bag with a permanent marker. Refrigerate or freeze according to your storage plan.

Tips

Don’t overfill: Leave at least 1-2 inches (2.5-5 cm) of headspace between the food and the open end. Overfilling can cause the bag to wrinkle and prevent a proper seal.
Freeze liquids first: For soups, sauces, or marinades, freeze them in a tray or container before vacuum sealing. This prevents the liquid from being pulled into the machine, which can damage it and ruin the seal.
Use the “Moist” setting if available: Some vacuum sealers have a “Moist” or “Gentle” mode for wet foods. If your machine has it, use it for raw meat or marinated items to avoid over-vacuuming.
Double-seal for extra safety: For long-term freezer storage (over 6 months), run the “Seal Only” function a second time, about 1/4 inch (0.6 cm) below the first seal. This creates a backup seal in case the first one fails.

Serving Suggestions

Use vacuum-sealed portions for sous-vide cooking—place the sealed bag directly in a water bath at your desired temperature.
Seal individual portions of cooked grains, roasted vegetables, or proteins for quick weekday meals; simply reheat in boiling water or a microwave-safe bag.
Vacuum-seal dry goods like coffee beans, nuts, or flour to extend their shelf life and keep them fresh.

Variations

Marinating: Place meat and marinade in the bag, vacuum seal, and refrigerate. The vacuum process forces the marinade into the meat faster than traditional methods—typically ready in 30 minutes instead of hours.
Cheese storage: Vacuum-seal hard cheeses like cheddar or gouda to prevent mold and drying. Wrap the cheese in parchment paper first to allow it to breathe, then seal the bag.
Vegetable blanching: Before freezing vegetables, blanch them in boiling water for 1-2 minutes, then shock in ice water, dry thoroughly, and vacuum seal. This preserves color and texture.

Storage and Reheating

Refrigerator: Vacuum-sealed cooked foods keep 3-4 days (same as any refrigerated leftovers). Raw meat can be refrigerated for 1-2 days before cooking.
Freezer: Vacuum-sealed raw meat and poultry can be frozen for 6-12 months, and cooked dishes for 2-3 months, without freezer burn. Always label with the date.
Reheating: For sous-vide, reheat sealed bags in a water bath at 140°F (60°C) for 15-30 minutes, depending on thickness. For reheating in the microwave, transfer food to a microwave-safe container first—do not microwave the vacuum bag unless it’s specifically labeled safe.
Thawing: Thaw vacuum-sealed raw meat in the refrigerator overnight, or in cold water for faster thawing. Never thaw at room temperature.

Frequently Asked Questions

Can I reuse Kirkland vacuum sealing bags? Yes, if the bag is intact and clean after use. Wash with warm soapy water, rinse well, and dry completely before reusing. Do not reuse bags that have held raw meat or fish unless you wash them thoroughly in hot, soapy water—but for safety, it’s best to use them only once for raw proteins.

Why is my bag not sealing properly? The most common cause is moisture or food particles on the sealing area. Ensure the open end is dry and clean. Also, check that the bag is placed flat in the sealer channel and that the lid is fully closed. If the seal is still weak, try using the “Seal Only” function to create a new seal just below the previous one.

Can I use these bags in a sous-vide water bath? Yes, Kirkland bags are BPA-free and safe for sous-vide cooking. Make sure the water temperature is within the bag’s rated range (typically up to 212°F/100°C). Always cut the bag open before serving.

How do I vacuum seal liquids without making a mess? Freeze the liquid first in a tray or ice cube tray, then transfer the solid blocks to the bag and vacuum seal. Alternatively, use the “Moist” setting on your sealer, but freezing is the most reliable method.

Are these bags safe for microwave reheating? Most vacuum bags are not microwave-safe. Check the packaging for a microwave-safe label. If not indicated, transfer food to a microwave-safe dish before reheating.

What is the maximum shelf life of vacuum-sealed food? Vacuum sealing extends shelf life by removing oxygen, but it does not make food shelf-stable. Refrigerated items still follow the 3-4 day rule, and frozen items last 6-12 months for meat, 2-3 months for cooked dishes. Always check for signs of spoilage before eating.
