Appearance visual inspection includes projects such as the flatness and transparency of food composite bags. It is mainly used to detect whether there are obvious abrasions and pinhole in the performance of the composite bag, and whether there is pollution at the seal. The appearance check method is as follows:
① The inspection of "Bags". Place the center of the food composite bag and sway gently at the 40W solar light. Through the reflection light on the surface of the composite bag, you can clearly find out whether the surface of the composite bag is scratched or traces. Most of the drawing phenomenon is caused by the guidance roller of the bag making machine, so it is necessary to ensure that the guide roller is clean. In addition, no rotation of the guide roller will also cause the composite bag to cause drawing failure.
② Check the flatness of the composite bag. Put a composite bag on a flat desktop. If the surface of the composite bag is curved and tilted out or arched inward, it means that the flatness of the composite bag is poor. On the contrary, this shows that the flatness is good. Some: The temperature of the bag is high to destroy the stress of the inner layer of the composite bag; the structure composition is unreasonable; the material itself is uneven.
