How To Do Quality Control Of Stretch Film?

In the production process of stretch stretch film, online monitoring is an important link to ensure the quality of stretch stretch film and reduce waste. In order to meet the needs of different materials and stretch wrap films, stretch wrap film manufacturers use advanced detection technologies such as ultrasonics and lasers to improve the production efficiency of stretch wrap film product quality.

The ISRA VISION inspection system has good defect image resolution at very high production speeds. The detailed defect image can accurately identify the defects of the stretch film and find out the cause of the defect, thereby reducing the quality defects in the production process of the stretch film and improving the quality of the stretch film. In addition, some special defects such as gels that can slow down production can be found and removed before further processing. Advanced recognition software has a self-learning function that can compare the form, shape, contrast and other characteristics of defects. Operators can use identification software to make adjustments to the process to prevent the defect from recurring.

For stretch film manufacturers who want to save time and money, powerful software tools can be configured for inspection systems. Stretch film manufacturers can use enterprise data mining software packages to perform raw material analysis, process improvement and process optimization based on statistical reporting date/time, batch number, defect type, stretch film type or shift statistics of defect data. Defect data for each machine can be shared in different locations. The advantage is that stretch film manufacturers can quickly obtain accurate quantitative information. Based on data trends, corrective actions can be taken in an unresponsive manner, and maintenance schedules can be optimized to increase machine uptime and reduce scrap rates.

The automatic optical inspection system has become an important monitoring method to ensure 100% qualified stretch wrapping film. New technology web inspection technology uses line scan cameras to identify defects on webs or sheets. Images are acquired by high-resolution digital cameras, and high- and low-contrast defects are reliably detected with dedicated optical modules. Afterwards, the recognition software identifies these defects in the stretch wrap film and classifies them into gels, black spots, dirt, wrinkles, air bubbles, etc. To sum up, the process of on-line detection of stretch wrapping film is really important. In order to produce high-quality stretch wrapping film, product testing must be done well.
