Heat Sealer
Heat Sealer (Product Code: SLE/ET/08) is a table-top laboratory sealing instrument used to make controlled heat seals on plastic films and flexible packaging samples for seal and package testing. Two temperature zones are held by an auto-tuned PID controller up to 200 °C with 0.1 °C resolution, and a pneumatically moved jaw closes against a fixed jaw to form a 150 mm × 20 mm seal. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to packaging laboratories and colleges looking for laboratory instruments in India.

What Is the Heat Sealer Used For?
Seal quality depends on temperature, pressure and contact time, and a laboratory heat sealer lets each of these be repeated from one sample to the next. The operator places two layers of film between the jaws, the pneumatic jaw closes against the fixed jaw, and the heated zones fuse a strip 150 mm long and 20 mm wide. Because the PID controller works to 0.1 °C resolution, seals made on different days can be compared with confidence.
Packaging developers use it to find the lowest temperature that gives a sound seal on a new laminate, and quality laboratories prepare seal strips that are later pulled apart on a tensile tester to judge seal strength. Start low and raise the temperature in small steps, keep the jaw faces free of melted residue, and let the zones stabilise after every change. It also suits film and pouch exercises in engineering and packaging courses.
What to Specify When Ordering
- Mains supply at your site (listed supply: 230 V, 60 Hz, single phase, 15 A)
- Compressed-air availability for the pneumatic jaw (discuss with us)
- Whether the 150 mm × 20 mm seal size suits your sample format
- Quantity and delivery location
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab in Ambala, Haryana, supplies this heat sealer to flexible-packaging developers, film converters, packaging test laboratories and engineering institutes in India and international markets.
Questions about jaw faces, controller settings or site services such as compressed air can be raised with us before ordering. The ScienceLab company profile has more about the business.

- Computerised Tensile Tester — can pull sealed strips apart when seal strength is checked.
- Static and Kinetic Friction Tester — checks the slip of the same packaging films.
- Inclined Plane Tester — measures film friction from the slip angle.
- Melt Flow Index Tester — characterises the melt flow of sealant polymer grades.

Frequently Asked Questions
What seal size does the Heat Sealer produce?
The Heat Sealer produces a seal 150 mm long and 20 mm wide between one fixed jaw and one pneumatically moved jaw, which suits strip samples for peel and seal-strength testing of films and laminates.
What temperature control does the Heat Sealer have?
The Heat Sealer uses an auto-tuned PID controller with a temperature range up to 200 °C and a resolution of 0.1 °C, serving two temperature zones so that sealing conditions can be repeated closely.
How are the jaws operated?
On the Heat Sealer one clamping jaw is fixed and the second is moved by pneumatic action to close on the film. Confirm compressed-air availability at your laboratory with us when you request a quotation.
What power supply does the Heat Sealer need?
The Heat Sealer is listed for a 230 volt, 60 Hz, single-phase supply rated at 15 amperes. Confirm your site’s voltage and frequency with us before ordering so any difference can be resolved before dispatch.
Is the Heat Sealer a bench unit?
Yes. The Heat Sealer is table-top mounted with a daylight of 50 mm, so it sits on a laboratory bench beside other packaging test instruments rather than needing floor space.
Who supplies the Heat Sealer?
The Heat Sealer is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to packaging, film and engineering laboratories in India and international markets.
What does a quotation request need?
For a Heat Sealer quotation, state the quantity, delivery location, your mains supply and whether compressed air is available on site. Send these details through the contact page or add the product to the enquiry cart.
