Pouch and Bag Continuous Band Sealing Machines

Continuous band sealing machines, also known as heat sealing machines, are sophisticated pieces of equipment offering efficient, reliable and versatile sealing solutions across various sectors, particularly in the food and drink, pharmaceutical and chemical industries. Our pouch and bag sealing machines function by continuously feeding bags through a conveyor belt, that can operate both vertically or horizontally, and pass through heated sealing jaws, fusing the thermoplastic material together to create a tight seal. Through precise temperature control, all sealing is highly consistent and of high quality, with easily adjustable temperatures to work with different material thicknesses and types.

What Is a Continuous Band Sealing Machine?

A continuous band sealing machine is a type of equipment used to seal bags or pouches containing various types of products. It is commonly used in the food, pharmaceutical and chemical industries to ensure that products are properly contained and protected from outside elements.

A bag sealer can also be known as a pouch, sack or Doypack sealing machine. It relies on the melting of two polymer layers, such as polyethylene and polypropylene to form a bond. These layers can be a single unsupported layer or monolayer, or they can be more than one layer called a laminate. The Autopack range of continuous heat sealers can handle any heat-sealable packaging material.

A bag and pouch sealing machine is effectively used where the operator presents the top of a bag, pouch, Doypack or sack to be sealed between two heated jaws. The operator will press a foot pedal and the pressure and heat seal the polymer layers together.

This is where a continuous band sealing machine can streamline operations with a more automated process with these machines heat-sealing the packs as they move through the heat sealer – usually supported on a conveyor. This allows for the operator to continually feed the sealer and so increase the throughput or do another task – such as filling the bag, pouch, Doypack or sack.

Types of Heat and Band Sealing Machines We Provide

Autopack provides two types of vertical continuous band sealing machines. The standard vertical SV30 and the SV30USD machines will run all types of bags, pouches, Doypacks and sacks.

Vertical Band Sealer Machines

A vertical band sealer is best suited for products that need to be filled as they are being sealed, such as liquids or powders, highly benefiting food and chemical industries.

Horizontal Sealing Machines

A horizontal sealing machine is ideal for flat items, and the height and weight of your packed bags will determine the size of the heated sealer. The horizontal machines will continuously move along your bags allowing for streamlined sealing.


Our Sealing Machines

The SV-30US is the most popular sealing machine in the Autopack range. The SV-30US will run the widest range of pack styles and materials, with an easy setup and robust design. Advanced design features allow for retail high-quality leakproof seals to be produced time and time again on this machine.

Our Industries

View our wide range of innovative industrial packaging machines to speed up and automate your production line.

The Autopack heat sealers use heated elements behind a continuously moving heated band to heat the bag, pouch or Doypacks. The heater elements are spring-loaded and easily adjusted to provide the ideal pressure for a wide range and thicknesses of packaging materials and the hot seal then runs over an adjustable cooling block, smoothing out any spots to give you a perfect retail finish at 10-, 15 – or 20 mm wide seal options.

Each continuous pouch sealing machine comes in stainless steel as standard and with a fully synchronised conveyor that is controlled by the sealing head. One speed dial controls both the sealing head and conveyor at the same time so the packs travel down the sealing conveyor in perfect balance to give uniform parallel seals.

  • Changeovers between different materials of bags, pouches, Doypacks and sacks are easy, thanks to the external spring-loaded knobs that allow you to alter the sealing and cooling pressures.
  • Utilise the latest digital technology in temperature control. The cooling block allows the operator to rapidly raise or lower the seal temperature.
  • Easily adjustable sealing height of the machine controlled from the front panel for precise applications.
