Film Free Shrink Tester vs Traditional Shrink Testing: Which is Better?
Shrink testing is a crucial step in the quality control process of packaging materials. It determines the amount of force required to shrink a material to its final size and shape. Traditionally, these tests were conducted using hot water baths and rulers to measure the amount of shrinkage.
However, with new technologies, a newer method called Film Free Shrink Testing has emerged. This method uses a digital device and a non-contact measurement system, which eliminates the need for hot water baths, lab technicians, and rulers.
Here we compare the two methods to determine which is better:
1. Accuracy.
Traditional shrink testing is highly accurate and has been used for years by the packaging industry. Measurements are taken manually by trained lab technicians, and the numbers are recorded and reported.
Film Free Shrink Testing uses modern technology, and the accuracy is equally impressive. The digital device takes measurements with precision, and the data is stored and analyzed automatically, eliminating any room for human error.
2. Speed.
Traditional shrink testing is a labor-intensive process that takes time. The packaging material needs to be cut, shaped, and then tested in a hot water bath. The entire process can take hours, if not days, to complete.
In contrast, Film Free Shrink Testing is fast and efficient. The device can test a complete wrap in minutes. The data is recorded instantly, making reporting and analysis faster and more efficient.
3. Cost.
Traditional shrink testing requires a lot of equipment, including hot water baths, rulers, and skilled lab technicians. This can add up to high costs for packaging companies.
Film Free Shrink Testing, on the other hand, eliminates the need for hot water baths and lab technicians, reducing costs for packaging companies.
4. Flexibility.
Traditional shrink testing is limited in terms of material size and shape. The hot water bath can only accommodate certain sizes and shapes, and the final testing requires manual measurements.
Film Free Shrink Testing is more flexible, as it can test any material size and shape. The device can be programmed for different test specifications, and the final results are automatically recorded and analyzed.
5. Safety.
Traditional shrink testing involves hot water baths, which pose safety risks for lab technicians. Accidents can occur, and the potential for burns is high.
In contrast, Film Free Shrink Testing is completely safe. There is no need for hot water baths or manual handling of the material, eliminating any safety risks.
In conclusion, both methods have their advantages and disadvantages. While traditional shrink testing has been used for years in the industry and is highly accurate, it is a slow and expensive process that involves safety risks.
On the other hand, Film Free Shrink Testing is faster, more efficient, and eliminates safety risks. It may be more expensive initially for packaging companies to invest in the technology, but it can save money and time in the long run.
Ultimately, the choice between the two methods comes down to the specific needs of the packaging company and their priorities in terms of speed, accuracy, and cost.
