Impulse Heat Sealer IS400C With Integrated Cutter

Our Impulse Heat Sealer IS400C provides a practical way to seal polythene bags and lay flat tubing up to 400mm wide, which equals approximately 15.75 inches.

The 400mm measurement refers to the maximum usable length across the sealing bar. Therefore, the machine can accommodate suitable bags or lay flat tubing measuring up to 400mm wide. It does not refer to the physical width of the complete machine.

The integrated cutter also allows users to trim excess film or cut lay flat tubing after sealing. Consequently, businesses can create bags in the required length while completing both sealing and trimming work at one packing station.

Impulse Heat Sealer IS400C Specifications

The maximum film capacity refers to two layers of film, each measuring up to 150 microns thick. However, sealing performance can vary according to the film material, thickness, cleanliness and selected heat setting.

Impulse Heat Sealer IS400C 400mm Sealing Capacity

The 400mm figure describes the maximum length of the sealing bar. As a result, the Impulse Heat Sealer IS400C can create a seal across bags and lay flat tubing measuring up to 400mm, or approximately 15.75 inches, wide.

For example, users can position the open edge of a suitable 350mm-wide bag across the sealing bar and close the arm to create a complete seal. Likewise, they can use lay flat tubing up to 400mm wide to manufacture bags in custom lengths.

The material must sit fully across the sealing bar without creasing or extending beyond its usable length. Therefore, check the actual width of the bag or tubing before ordering the machine.

Where the material measures exactly 400mm wide, position it carefully so the complete opening remains within the sealing area.

Impulse Heat Sealer IS400C Integrated Cutter

The integrated cutter distinguishes this machine from a standard heat sealer without a cutting function.

After creating a seal, users can operate the cutter to trim unwanted material. Consequently, the Impulse Heat Sealer IS400C suits lay flat tubing because it can help create individual bags from a continuous roll.

The cutter can also remove excess film above a completed seal, helping produce a neater and more consistent finish.

However, the blade remains a sharp component. Therefore, keep fingers away from the cutting path, operate it only as instructed and supervise inexperienced users appropriately.

Creating Bags with the Impulse Heat Sealer IS400C

Lay flat tubing provides a flexible way to create bags in different lengths. The Impulse Heat Sealer IS400C can accept suitable tubing up to 400mm wide.

To create a bag:

1. Select lay flat tubing no wider than 400mm.
2. Pull out the required length.
3. Position the tubing flat across the sealing bar.
4. Lower the sealing arm to create the first seal.
5. Allow the seal to cool briefly.
6. Use the integrated cutter to separate the section.
7. Insert the product through the open end.
8. Seal the remaining open end.

This process allows users to adjust the bag length according to the product. Therefore, one roll of tubing can package several products with similar widths but different lengths.

Always allow enough extra material for the seals and easy product insertion. Furthermore, make sure the item will pass through the tubing without stretching or damaging the film.

Sealing Pre-Made Bags with the Impulse Heat Sealer IS400C

The machine can seal suitable pre-made polythene bags up to 400mm wide.

First, place the product inside the bag without overfilling it. Next, remove excess air where appropriate and ensure the open edge lies flat across the sealing bar. Then lower the arm firmly for the required sealing cycle.

Keep the product and any loose contents away from the sealing area. Otherwise, trapped material, moisture, dust or creases may prevent the machine from creating a complete seal.

After sealing, inspect the seal across its full width. If necessary, adjust the sealing control gradually and test another empty bag before continuing.

Impulse Heat Sealer IS400C Adjustable Sealing Control

Different films may require different sealing times. Therefore, the Impulse Heat Sealer IS400C includes an adjustable sealing control that allows users to match the sealing cycle to the material.

Start with a low setting when testing a new bag or tubing specification. Then increase the setting gradually until the machine creates a continuous seal without burning, shrinking or excessively distorting the film.

A setting that is too low may produce an incomplete or weak seal. Conversely, an excessively high setting may melt through the material or damage the sealing components.

Once you find a suitable setting, record it for future batches using the same film. However, recheck the seal whenever the film specification, thickness or supplier changes.

How to Use the Impulse Heat Sealer IS400C

Position the machine on a stable, level and heat-resistant work surface. In addition, allow enough space around the sealing arm and cutter for safe operation.

Before sealing:

1. Inspect the power cable, plug and machine.
2. Check the sealing strip and cutter for visible damage.
3. Connect the machine to a suitable 230V power supply.
4. Select a low initial sealing setting.
5. Place a clean test piece across the sealing bar.
6. Lower the arm firmly and evenly.
7. Allow the sealing cycle to complete.
8. Raise the arm and inspect the finished seal.
9. Adjust the setting gradually where necessary.

Impulse technology applies heat during the sealing cycle. Consequently, users should avoid repeatedly operating the machine faster than its recommended duty cycle.

Always follow the operating instructions supplied with the machine.

Checking Impulse Heat Sealer IS400C Seal Quality

A suitable seal should run continuously across the material without gaps, burns or excessive distortion.

Check that:

• The seal covers the complete bag width
• Both film layers have bonded together
• No creases cross the sealing area
• The film has not burned through
• The seal remains closed under normal handling
• The product has not become trapped within the seal
• The cutter has produced a controlled edge

If the seal separates easily, increase the setting slightly and repeat the test. However, if the film melts through, reduce the setting and allow the machine to cool before testing again.

A successful test seal does not automatically confirm suitability for every application. Therefore, businesses should also assess the complete package under the expected filling, storage and transport conditions.

Impulse Heat Sealer IS400C Film Thickness Capacity

The Impulse Heat Sealer IS400C can seal suitable film up to 2 x 150 microns. This means the sealing area may contain two film layers, each measuring up to 150 microns or 0.15mm thick.

However, maximum capacity does not guarantee compatibility with every heat-sealable material at that thickness. Film formulations, additives and surface contamination can affect the result.

Accordingly, test the actual bags or tubing before beginning a production run. If you remain unsure, contact us with the material type, thickness and width.

Impulse Heat Sealer IS400C for Packing Areas

The tabletop format suits packing benches, warehouses, production rooms and fulfilment areas.

The 400mm sealing bar offers additional capacity compared with the smaller 200mm and 300mm models. Consequently, businesses can seal a wider range of medium-sized and larger bags or lay flat tubing.

The machine measures approximately 610mm x 220mm x 110mm, which equals approximately 24.02 x 8.66 x 4.33 inches. Therefore, allow enough bench space for the complete machine, sealing arm and materials.

Furthermore, the machine weighs approximately 6.12kg, or 13.49lb. Although users can reposition it when necessary, place it securely during operation and avoid moving it while connected or hot.

Impulse Heat Sealer IS400C Safety Information

The sealing element and surrounding components may become hot during use. Therefore, keep fingers, clothing and combustible materials away from the sealing area.

The integrated cutter also contains a blade. Consequently, only trained or appropriately supervised users should operate the machine.

Before cleaning, inspecting or replacing components:

1. Switch off the machine.
2. Disconnect it from the power supply.
3. Allow it to cool completely.
4. Follow the supplied maintenance instructions.
5. Use only compatible replacement components.

Do not use the machine if the power cable, plug, casing, sealing bar or cutter appears damaged. Instead, remove it from service and arrange appropriate inspection or repair.

Maintaining the Impulse Heat Sealer IS400C

Regular inspection helps maintain consistent sealing performance.

Keep the sealing area clean and remove loose pieces of film after the machine has cooled. Additionally, inspect the sealing element, PTFE strips and cutter for wear or damage.

Do not scrape the sealing surface with sharp tools. Furthermore, do not allow melted film to build up because residue may affect later seals.

Consumable sealing components may require replacement during the machine’s working life. Therefore, follow the maintenance instructions and use compatible replacement parts designed for the IS400C.

Store the machine in a clean, dry location when not in use. Keep the sealing arm lowered only where the manufacturer’s instructions recommend it.
