To reduce defective products and waste products, we must first understand the main reasons for the formation of defective products and waste products. The film coating process is not good for the car, the cloth, the film, and the color film. The tension controller fails, the film edge sticks, the film edge breaks, and the diaphragm breaks.

2. The process causes the ends of the product to be reinforced. Or release film, leak coating. Or the product change standard, the circular weaving cloth waste silk breaks the film, the continuous joint in the color film. Printed film surface ink lines, etc., will form waste.

3. Plastic packaging manufacturers said that every detail in the operation can be done to reduce the number of defective products and waste products. Changing coating materials, changing standards, changing coating ratios, climate change, etc. will also form a coating quality shake.
