Heat Sealers


We pride ourselves on delivering the most effective heat sealing machinery, including impulse heat sealers and continuous heat sealers to suit your needs. Our wide range of packaging machines are integral to businesses across the world.

Whether you’re looking for specialist medical heat sealers, industrial sealers or commercial sealing machines, we are here to offer advice and ensure you’re left with the right sealing machine to suit your needs.

What Are The Different Kinds of Heat Sealers?
There are three main types of heat sealers: manual, semi-automatic, and automatic. Each has its own advantages and disadvantages that you should consider before deciding which is the best type of heat sealer for your needs.

Manual Heat Sealers
Manual heat sealers, also known as an impulse heat sealer, are the most basic and affordable type of heat sealer. Impulse sealers are easy to use and require very little training to operate. However, they are also the slowest type of heat sealer and can be somewhat inconsistent in their sealing quality. If you have a small business with low sealing volume, a manual heat sealer may be the best option for you.

Semi-Automatic Heat Sealers
Semi-automatic heat sealers are faster and more consistent than manual heat sealers. They also tend to be more expensive. If you have a medium-sized business with moderate sealing volume, a semi-automatic heat sealer may be the best option for you. They are mostly automated, but are rarely suitable for heavy-duty use, such as medical, industrial or regular commercial use.

Continuous Heat Sealers
Continuous heat sealers, also known as automatic sealers, are the fastest and most consistent type of heat sealer. They are also the most expensive. If you have a large business with high sealing volume, an automatic heat sealer may be the best option for you.

Continuous heat sealers are typically used for commercial and industrial applications.

What Are The Best Brands of Heat Sealers?
While there are many brands of heat sealer available, Hawo heat sealers are the most reliable, particularly their automatic sealers. If you’re looking for a high-quality, heavy-duty heat sealer, Hawo is the brand for you. They also offer affordable, reliable consumable parts, including heating elements, flat tubing and more.

Another popular brand of heat sealer is Minipack. Minipack also offers a wide range of sealing machines, from manual to automatic, making them a good choice if you’re not sure which type of heat sealer is best for your needs.

If you need any help deciding which heat sealer is best for your business, don’t hesitate to contact Valdamark. Our team of experts are always on hand to offer advice and guidance to ensure you’re left with the perfect packaging solution to suit your products and production facilities.

What Are Impulse Heat Sealers?
Impulse heat sealers are the most popular type of heat sealer. They work by passing an electric current through a heating element, which then heats up and melts the plastic film.

The impulse sealer has a sensor that detects when the correct amount of heat has been reached, at which point it cuts off the current and allowed the element to cool. This process creates a strong, consistent seal.

What Are Foot Operated Impulse Sealers?
Foot operated impulse sealers are a type of impulse heat sealer that is activated by a foot pedal, rather than a button. This allows the operator to keep both hands free to feed the material into the sealer.

What Are Continuous Heat Sealers?
Continuous heat sealers, or continuous bag sealers work in a similar way to impulse heat sealers, but instead of having a heating element that is turned on and off, they have a constantly heated sealing bar. This makes them much faster than impulse sealers, as there is no need to wait for the element to cool down between seals. However, they are also more expensive.

Are Constant Heat Sealers the Same As Continuous Sealers?
No, constant heat sealers are not the same as continuous sealers.

A constant heat sealer has a heating element that remains at a constant temperature, meaning it can seal multiple bags in quick succession.

A continuous sealer, on the other hand, has a sealing bar (or multiple sealing bars) that is heated and cooled in cycles, meaning it can only seal one bag at a time, but will typically seal them extremely quickly.

What Are The Advantages of Heat Sealers?
There are many advantages of heat sealers, which is why they are so popular. Some of the main benefits include:

  • Heat Sealers are fast and efficient
  • They create a strong, consistent seal
  • Most Heat / Bag Sealers are easy to use, and require very little training
  • They are available in a range of sizes and styles to suit your needs, your own bag sizes and more.


What Are Industrial Heat Sealers?
Industrial heat sealers are high-quality heat sealers that are designed for heavy-duty use. They are often used in industrial and commercial settings, such as food production, pharmaceuticals and more. Industrial heat sealers are usually larger and more powerful than standard heat sealers, and can seal thicker materials.
