Hawo HPL ISZ Impulse Heat Sealer 300mm
This manual impulse heat sealer is perfect for welding materials such as polyethylene, polypropylene, PVC, and polyamid. Thin Pe laminated paper and aluminium composite foil welding can also be done. For a constant manual bag sealer see the Hawo HPL WSZ range.
The market leading design focuses around optimal seal quality. This portable heat sealer allows the operator to easily work in small spaces. Or when sealing on site.
It's also intended for those that produce their own packaging and want more manoeuvrability.
Perfect for when the items being packaged may vary in size. Or be awkward to seal.
As well as these excellent ergonomic features this sealer is designed with a 'built to last' mentality. No 'heat up time' is standard here. Allowing this unit to perform for the most demanding of sealing projects.
This impulse sealer is easy to handle thanks to a separate impulse power supply box.
The welding process is automatic and can be adjusted to suit your temperature requirements. It can even be adjusted after you close the tong.
These heat sealers can also be used in conjunction with on of our table mountings as an extra. These allow for the best usability and ease of storage.
This machine can be used in some medical packaging environments but where ISO 11607 packaging validation is required look here for suitable solutions.

Frequently Asked Questions
• What exactly is the Hawo ISZ Impulse Heat Sealer 300mm and what makes it a standout product?
The Hawo ISZ Impulse Heat Sealer 300mm is a professional, handheld impulse sealing tong designed for the reliable and efficient sealing of various flexible packaging materials. Its standout features include its portability, immediate readiness for use (no warm-up time), and the ability to produce a strong, consistent ceramic sealing weld, making it a market leader for optimal seal quality.
• How does Hawo's impulse sealing technology work in this 300mm model?
The Hawo ISZ Impulse Heat Sealer utilizes impulse sealing technology, meaning the ceramic sealing jaw only heats up for a brief moment when the tongs are closed and pressure is applied. This "impulse" of heat creates a strong, hermetic seal, and then the sealing jaw cools down quickly, which contributes to energy efficiency and user safety.
• Is the Hawo ISZ Impulse Heat Sealer 300mm truly portable for on-site sealing?
Absolutely! The Hawo ISZ 300mm is explicitly designed with mobility in mind. It's lightweight and easy to handle, coming with a separate transformer box for its power supply, allowing operators to easily work in small spaces or when sealing on site, giving you ultimate flexibility.
• What types of materials can the Hawo ISZ Impulse Heat Sealer 300mm effectively seal?
This versatile Hawo sealer is perfect for welding a wide range of thermoplastic materials, including polyethylene, polypropylene, PVC, polyamide, thin PE-coated paper, and even aluminium composite foil, ensuring you can tackle diverse packaging needs.
• What's the typical sealing width provided by the Hawo ISZ 300mm heat sealer?
The Hawo ISZ Impulse Heat Sealer 300mm produces a consistent and robust 3mm (0.12 inch) wide sealing seam, which is ideal for creating strong and secure closures on your packaging.
Relevant products you may want to consider:
• For what kind of products or items is the Hawo ISZ Impulse Heat Sealer 300mm particularly well-suited?
This Hawo sealer is excellently suited for packaging items that vary in size or are awkward to seal, such as large industrial products, machinery components, spare parts for shipping, office supplies, food, photographic agents, and even medical products where ISO 11607 validation isn't strictly required.
• Can I use the Hawo ISZ 300mm for creating my own custom-sized bags or pouches?
Yes, definitely! Since it's a handheld tong, the Hawo ISZ 300mm gives you the freedom to create custom-sized bags or seal at any point along a film, which is incredibly useful for users who produce their own packaging and require more maneuverability.
• How do I adjust the sealing time on the Hawo ISZ Impulse Heat Sealer 300mm for different film thicknesses?
The sealing time on the Hawo ISZ 300mm is infinitely adjustable directly on its "W.I.N.G" impulse power pack. This allows you to fine-tune the heat applied to suit various material thicknesses, ensuring an optimal and reliable seal every time. You can even adjust it after you've closed the tong.
• Is there a specific "warm-up" period required before I can start sealing with the Hawo ISZ 300mm?
No, that's one of the best things about the Hawo ISZ 300mm! There's absolutely no heat-up time required; the unit is ready to perform instantly, making it incredibly efficient for demanding sealing projects.
• Can the Hawo ISZ 300mm be used as a static, benchtop sealer if needed?
Yes, it can! While designed for handheld flexibility, the Hawo ISZ 300mm can also be used in conjunction with an optionally available table mounting clamp, transforming it into a static table model for added usability and ease of storage in a fixed workstation.
Relevant products you may want to consider:
• How do I ensure an optimal and consistent seal when using the Hawo ISZ Impulse Heat Sealer 300mm?
To achieve an optimal and consistent seal, it's crucial to correctly adjust the sealing time on the impulse power pack according to the material thickness. Ensure the material is flat and free of wrinkles in the sealing area. The automatic impulse process ensures the seal is completed correctly once the tongs are closed.
• Is it suitable for sealing delicate items that might be sensitive to excessive heat?
Because the Hawo ISZ 300mm is an impulse sealer, the heat is applied only for a short, controlled duration, and the jaws cool quickly. This precise control helps prevent excessive heat exposure to delicate items, making it a safer option for heat-sensitive contents compared to constant heat sealers.
• What is the maximum film thickness that the Hawo ISZ 300mm can seal effectively?
The Hawo ISZ Impulse Heat Sealer 300mm is designed to seal a film thickness tolerance of 2 x 0.5 (0.02 inches), which translates to effective sealing of various common packaging films.
