Film Slitting MachineThere are foreign objects such as dust and small insects in the film roll.
The slitting process of the film requires unwinding the mother roll and then slitting and rewinding, which creates conditions for the entry of external foreign objects. Therefore, the cleanliness and purification of the production workshop environment play a very important role in ensuring the quality of the film.
In addition, contamination from paper scraps on the film end face, dirty hands of operators and packers contaminating the film roll, uneven sizes at both ends of the paper tube, bruises, poor packaging, etc., are also quality issues that are prone to occur during the slitting process. We must pay attention to every detail during operation and packaging, such as neatly placing and tightly adhering the film to the paper tube before starting the slitting machine, ensuring the film does not extend beyond the end face of the paper tube, maintaining cleanliness of the operators' hands, and ensuring the hygiene of the slitting area. The packaging and handling process should be done with care, ensuring stability when unloading the film roll, avoiding impact on the film surface. The sealing of boxes, sealing paper caps, sealing paper wraps, and label application during the packaging process must strictly follow the specified requirements, positions, and dimensions, without arbitrary actions, to ensure the quality of the film products at every stage.

Although each quality index of the film has an upper and lower tolerance limit, and the tolerance is the acceptable limit of product quality, it does not mean that our products can continuously be at or near the upper and lower limits of tolerance during the slitting process. When we find that the product is continuously at or near the quality tolerance limits, it indicates that there must be an abnormal situation in production operations or equipment. We must take immediate corrective measures to eliminate influencing factors and ensure the continuous stability and improvement of product quality.
On the surface, slitting is the process of dividing a film of a certain width into several equal or unequal width products through the action of a cutting knife. The slitting process is relatively simple, but often contains mysteries within its simplicity. In actual production, slitting operations are a very important link in film production. The quality of slitting directly affects the quality of the film and the quality of use for the user. Therefore, the quality of slitting must not be underestimated during the film production process. Only by fully recognizing the importance of the slitting process and grasping the basic essentials of slitting can we minimize consumption, ensure the best product quality, fully meet customer needs, and provide the most reliable guarantee for the quality of film products.
