One Point Heat Seal Tester – Touch Screen

Presto Instruments' One Point Heat Seal Tester – Touch Screen is a precision laboratory heat sealer designed to test single-point heat sealing performance on flexible packaging materials. With an intuitive touch screen HMI and PID temperature controller, this heat seal tester helps QC teams and manufacturers determine ideal sealing parameters — ensuring seals meet required strength and safety standards.

As a trusted laboratory testing instrument manufacturer and Supplier in Ghana, Presto Instruments designs the One Point Heat Sealer to meet industrial standards—a reliable choice for pharmaceutical, food, cosmetic, and FMCG packaging quality control.

What is a one-point heat sealer touch screen?

The One Point Heat Seal Tester– Touch Screen is a laboratory-grade heat seal tester used to create and evaluate a localized heat seal at one precise point—such as a corner, spout, or specific spot on a bag or pouch—applying controlled heat, pressure, and dwell time to study how a flexible packaging material seals under real-world conditions.

Unlike conventional bar-type sealers, this single-point heat sealing instrument is purpose-built for testing small pouches, corner seals, and tricky geometries that are hard to seal uniformly. Its touch screen HMI replaces manual knobs with a graphical, menu-driven panel—letting operators set, monitor, save, and recall parameters in a few taps, making it a preferred packaging testing instrument for modern QC labs.

How Does the One-Point Heat Seal Tester Work in Ghana Industries?

The heat sealer applies controlled heat and pressure to a single, defined point on the packaging material:

Sample (film, laminate, or pouch) placed at the sealing location.
Temperature, pressure, and dwell time set via touch screen.
A PID controller + Pt-100 RTD sensor heats the head to the exact temperature.
Heated head presses the sample for set dwell time, fusing the layers.
Head releases automatically; sample removed for seal-strength evaluation.
Touch screen logs parameters in real time for repeatable results.
Ramp rate: 15°C/minute
ASTM F2029.

Technical Problems It Solves

Inconsistent localized seals: Bar sealers can't isolate a single contact point — this instrument tests exactly that spot, eliminating guesswork on corners and irregular geometries.
Poor traceability: The touch screen automates parameter setting and logging, eliminating manual knobs and logbooks entirely.
Temperature drift is a problem. A PID controller with a Pt-100 RTD sensor helps to get the sealing condition every time.
Standards non-compliance is a concern. Our setup follows ASTM F2029. This way, we are sure our in-house data will pass audits.

Key Features

The touch screen interface is really easy to use because it has menus instead of manual knobs. This makes it a lot faster to set up.
The PID temperature control is very good at keeping the temperature stable and precise. This means you get results every time you use it.
The Pt-100 RTD sensor is very accurate. It senses the temperature all through the cycle.
You can test areas with the single-point sealing capability. This is something that standard bar sealers cannot do.
You can see what is going on with the data visibility feature. It shows you the temperature, time, and pressure over time.
The safety features are very important because they keep the operator safe while sealing.
Presto is a manufacturer, and they support this product. They are experts and leading manufacturers.
The rapid heating ramp rate is very fast. It can heat up to fifteen degrees Celsius per minute. This is double the speed of a sealer.
This product is ASTM F2029 compliant.
The Automatic Test History Log. It writes down data like the date and time and sample ID by itself
