The fastest way to open a vacuum sealed bag

The easiest method is to find the small notch or slit usually molded into one of the top corners of the bag, then pull the two layers apart along the sealed edge. If there is no notch, use sharp kitchen scissors or a sealing knife to cut along the top edge—stay as close to the seal as possible so you do not cut into the food or item inside. Once you have opened the top 2 to 3 inches, you can peel the layers apart by hand.

Do not try to tear the bag open with your hands alone. Vacuum sealed bags are designed to be airtight and extremely strong, and pulling hard will either exhaust you or tear a hole in the middle of the bag, spilling contents everywhere. A small cut at the sealed edge takes five seconds and works every time.

Key Takeaways

  • Look for a small notch or slit molded into the top corner of the bag—this is the intended opening point and requires only a gentle pull to separate the layers.
  • If no notch exists, use kitchen scissors or a sealing knife to cut along the top sealed edge, staying as close to the seal as possible to avoid cutting the contents.
  • Cut only 2 to 3 inches along the seal, then peel the bag open by hand rather than trying to tear it.
  • Never pull hard on the bag itself—the vacuum seal makes the material too strong to tear by hand and you risk puncturing the middle instead.

Using the notch if your bag has one

Many vacuum sealed bags come with a small notch or tear-line molded into one of the top corners. This notch is the manufacturer's intended opening point. Locate it by running your thumb along the sealed edge at the corners—you will feel a slight indent or small slit.

Once you find the notch, grip one layer of the bag on each side of the notch between your thumb and forefinger. Pull the layers apart gently and steadily. The seal will separate cleanly along the top edge. You should be able to open 6 to 8 inches of the seal this way without any tool. If the notch is very small or hard to find, a fingernail or the edge of a butter knife can help you get a grip on the layers.

Cutting open bags without a notch

If your bag has no notch, you will need to cut the seal. Use a pair of sharp kitchen scissors or a sealing knife—a short, thin blade designed for opening packages. Position the blade along the very top of the sealed edge, parallel to the seal itself.

Cut slowly and deliberately along the seal from one corner toward the other, staying as close to the sealed edge as possible. This keeps your blade away from the food or item inside. You only need to cut 2 to 3 inches to create an opening large enough to peel the bag apart by hand. Once you have made the initial cut, grip the two layers and pull them apart gently. The rest of the seal will usually separate without further cutting.

Avoid cutting perpendicular to the seal (straight down into the bag) because this risks hitting the contents. Also avoid using a knife with a long blade—the extra length makes it harder to control and easier to cut too deep into the bag.

Opening bags with delicate contents

If the bag contains something fragile—fresh herbs, baked goods, or electronics—take extra care when peeling the layers apart. After you have cut or opened the seal, peel slowly and watch for any sharp edges on the plastic that might snag the contents.

For very delicate items, you can widen the opening slightly before reaching in. Make a second small cut along one of the side seals, perpendicular to the top seal, to create an L-shaped opening. This gives you more room to remove the contents without bending or crushing them. Once the item is out, you can discard the bag or, if you plan to reseal it, set it aside carefully so the cut edges do not curl or tear further.

What to do if you tear the bag in the wrong place

If you accidentally puncture the middle of the bag instead of the seal, the vacuum is broken and the contents will no longer be protected from air. Remove the item when ready and transfer it to a new vacuum sealed bag, a freezer bag, or an airtight container, depending on what you are storing.

If the tear is small and you caught it right away, you can sometimes salvage the bag by sealing it again with a vacuum sealer or a heat sealer, but this works only if the tear is near an edge. A hole in the middle of the bag cannot be reliably resealed and will continue to let air in. For food, a torn bag means the contents will lose quality faster, so use them sooner rather than storing them long-term.

Tools that make opening easier

A sealing knife is a short, flat blade specifically designed for opening vacuum bags and other sealed packages. It costs $5 to $15 and gives you much better control than a regular kitchen knife because the blade is shorter and the handle is designed for this task. If you open vacuum bags regularly, one is worth having in your kitchen drawer.

A package opener or safety cutter is another option—these have a small, retractable blade that you roll along the seal. They are safer than knives because the blade is protected and you are less likely to cut yourself or the contents. A basic one costs $3 to $8.

For most home cooks, sharp kitchen scissors are sufficient and you probably already own them. The key is keeping them sharp—dull scissors will slip and tear the bag instead of cutting cleanly.

Frequently Asked Questions

Can I open a vacuum sealed bag without cutting it?

Yes, if the bag has a notch or tear-line molded into the top corner. Grip the two layers on either side of the notch and pull them apart gently. If there is no notch, you will need to cut the seal to open it safely.

Will opening the bag ruin the vacuum seal on the rest of it?

Yes. Once you open the bag, the vacuum is broken and air enters. If you want to store the remaining contents, transfer them to a new bag or an airtight container. You cannot reseal a bag that has been opened by cutting or peeling.

What is the best tool to use?

Sharp kitchen scissors work well for most people and cost nothing if you already own them. A sealing knife or safety cutter gives you better control and is worth buying if you open vacuum bags frequently. Avoid long kitchen knives because they are harder to control and more likely to cut the contents.

Can I open a vacuum sealed bag with my teeth?

Not safely. Vacuum bags are very strong and your teeth can slip, causing you to bite your lip or cheek. You can also swallow small pieces of plastic. Always use scissors or a knife instead.

What if the notch is too small to grip?

Use a fingernail, the edge of a butter knife, or a small flathead screwdriver to pry the two layers apart at the notch. Once you have separated them slightly, you can grip the layers with your fingers and pull the rest of the seal open.
