Collection: Heat Sealers

The right heat sealer depends on the packaging material, seal width, bag or film size and production volume. Impulse sealers are well suited to everyday packaging operations, while constant heat and automatic sealers can be more appropriate for demanding materials or higher-volume production environments.

Impulse sealers apply heat only during the sealing cycle, making them efficient for many everyday bag and film sealing applications. Constant heat sealers maintain a continuous operating temperature and are better suited to materials or applications requiring sustained, higher-temperature sealing.

Heat sealers can be used with a variety of compatible thermoplastic bags, films and packaging materials. Compatibility depends on the material composition, thickness and sealer specification, so always check that the machine is suitable for the packaging material you intend to use.

Choose a heat sealer with a sealing length suitable for the maximum width of the bags or film you regularly use. You should also consider material thickness and required seal width to ensure the machine provides a reliable seal for your packaging application.

Yes. Benchtop impulse heat sealers are a practical choice for warehouses, fulfilment centres and dispatch operations that regularly seal compatible bags and films. They provide quick, repeatable sealing without requiring the heating element to remain continuously hot between sealing cycles.

Automatic impulse heat sealers are useful when businesses need to increase packing speed or perform repetitive sealing throughout the working day. Hands-free operation can help streamline the process, particularly in production, fulfilment and higher-volume packing environments.

Handheld and portable heat sealers are useful when packaging is too large or awkward to bring to a fixed benchtop machine, or when sealing needs to take place at different locations. They can provide greater flexibility across warehouses, manufacturing facilities and industrial packing operations.

Yes. Selecting the correct heat sealer can make bag and film sealing faster and more consistent than less specialised manual methods. For businesses processing larger volumes, automatic or heavy-duty equipment can further improve throughput and help create a more repeatable packing process.

Consider the material being sealed, maximum bag or film width, material thickness, required seal quality and daily production volume. You should also consider whether you need a benchtop, handheld, automatic or floor-standing machine and whether replacement elements or other accessories are readily available.

Southgate supplies heat sealers for UK warehouses, manufacturers, fulfilment centres and industrial packaging operations. The range includes impulse, automatic impulse, handheld and portable, and constant heat sealers, alongside heat sealer kits, rollers and accessories.
