How to evaluate the heat sealing performance of paper plastic composite bags for stir fried products? Adopting the Three Springs Stone Heat Sealing Tester

The two things that stir fried products are most afraid of during storage and transportation are moisture and odor. As the mainstream packaging form, the sealing quality of paper plastic composite bags directly determines the shelf life and flavor stability of products. In order to evaluate the sealing performance of the bag body under different temperature, pressure, and time conditions, heat sealing performance testing is particularly crucial.

So, how to scientifically and accurately find the optimal heat sealing parameters for paper plastic composite bags? This is exactly where the RFY-05 paper plastic composite bag heat sealing tester for Sanquan Zhongshi fried goods products comes into play.

Why use a heat sealing tester? How important are heat sealing parameters?

The heat sealing quality of paper plastic composite bags is affected by various factors, such as material structure, type of heat sealing layer, heat sealing pressure, and heat sealing temperature.

If the temperature is not sufficient, the seal cannot be fully melted;

If the pressure is insufficient or uneven, it can lead to virtual sealing of the edge;

If the time is too short and the composite layer has not fully fused, it will be opened.

These issues directly lead to packaging leakage, cracking, and poor air tightness, thereby affecting the freshness and quality of fried products.

Therefore, conducting systematic heat sealing tests on packaging materials before production is a way for food companies and packaging factories to ensure reliable sealing.

RFY-05 Stir fried Products Paper Plastic Composite Bag Heat Sealing Tester - How to Achieve Accurate, Stable, and Highly Repetitive Heat Sealing Simulation?

The RFY-05 heat sealing tester developed by Sanquan Zhongshi is specifically designed for food packaging materials such as paper plastic composite bags. Its testing mechanism uses hot pressing sealing method:

Place the sample between the upper and lower hot heads, seal it by setting the temperature, pressure, and time, and find the optimal heat sealing combination parameters through multiple experiments, providing clear guidance for mass production.

Its core advantages are mainly reflected in the following aspects:

1. PID precise temperature control to achieve stable heat sealing

The RFY-05 paper plastic composite bag heat sealing tester for Sanquan Zhongshi's stir fried products adopts digital PID temperature control technology, which heats up quickly, controls temperature accurately, and can quickly reach the set value and maintain stability, providing reliable temperature conditions for the experiment.

2. Imported pressure sensing system to ensure true and controllable pressure

Pressure control directly affects the sealing effect.

The pressure sensing system used in this instrument greatly improves the accuracy of pressure regulation, further ensuring the accuracy and repeatability of test results.

3. The time accuracy has been improved to 0.01s, meeting the higher requirements of packaging enterprises

The heat sealing time is a key factor affecting the sealing fastness.

The RFY-05 paper plastic composite bag heat sealing tester for Sanquan Zhongshi's stir fried products supports a precise time setting of at least 0.01s, and is equipped with a unique contact timing method, making the testing time more accurate and the response more sensitive.

4. The heating of the hot head is uniform, and the upper and lower temperatures are independently controlled

Adopting an aluminum can sealed hot head structure to ensure consistent temperature distribution on the heating surface;

The upper and lower hot sealing heads can independently set the temperature and adapt to different structures of paper and plastic materials, providing flexibility for more complex sealing designs.

5. High degree of automation, more user-friendly operation

• Dual control mode of manual/foot pedal

• Automatic control testing process

• The heat sealing clip approaches smoothly, ensuring accurate reproduction of heat sealing in a short period of time

• All of this allows experimenters to conduct repeated tests more easily and reliably.
