Bag Sealers

Plastic Bag Sealing Machines: What You Need to Know

Bag sealers – also known as heat sealers or impulse sealers – remove the primary way air and moisture might contaminate a sealed food item by melting the plastic of the bag opening into a permanent seal. Once you've packaged your food in an appropriate heat-sealable bag, simply press the opening tabs between the heat elements of your plastic bag sealer, and it will secure the food against contamination. This process has several benefits:

• Storing air-sensitive food
• Confidently selling to-go food
• Marketing premade food for sale

Plastic sealing machines are safe and user friendly, requiring only an electrical outlet and countertop space upon which to work. The operator need only place the target opening between the heating elements, press down, and wait a few seconds for the heating elements to delicately melt the plastic together.

Common Questions About Bag Sealers

What is an impulse sealer used for?

Impulse bag sealers are used to create a strong seal on plastic bags to keep air, moisture, and other contaminants from affecting the quality of the product inside. Heat sealer machines function by quickly heating an element on either side of the machine's opening that can then be pressed firmly onto a sealable plastic bag to melt both sides of the bag together. This eliminates the weakest point in most bags: an unreliable seal across the opening. Reclosable zipper openings are not as secure as a heat-sealed package, and imperfect seals can lead to products losing their freshness before a customer gets to enjoy them.

The tighter seal provided by a plastic bag sealing machine reduces the amount of air and moisture that can get to your product, leaving it fresher than it would otherwise be. This is very valuable when storing products for long periods of time or sending products away from your kitchen in delivery or pick-up business models.

If your customers have to tear into a sealed bag to get their food, they know it hasn't been adulterated between your establishment and their dining room table. There are many ways to reassure your customers their food has been packaged securely, but a heat sealer machine is one of the most efficient as they work with a quick press, have flash heating, and beep to signify the bags are ready.

What utilities do I need to use a manual bag sealer?

These machines are easy to move and easy to operate. You'll need an electrical outlet and sufficient counterspace to set it up. Consult the product specification page for the individual model before making a purchase. Most of our heat sealers use a standard 120-volt outlet, meaning you won't need any special electrical work to get one up and running. Because of their small size, you can easily move your impulse bag sealer to storage when you don't need it.

Are plastic sealing machines safe?

The heating elements cool very quickly after use, so the danger of burns is minimal as long as operators are cautious. The heating elements do get very hot, so you want to make sure you only hit the appropriate part of a heat sealing bag and not any fingers or exposed flammable materials.
