In the film production process, the film masterbatch coloring is a very important part. If the production process is not rigorous enough, it is easy to cause a low product pass rate. So what should we pay attention to in this process?

1. The proportion of film masterbatch and raw materials used for fixing : different proportions will affect the color and cover rate;

2. Fixed production process: changes in process parameters need to be evaluated, otherwise product quality will be affected;

3. Fixed mixing time: color masterbatch and raw material specific gravity, particle shape is different, such as mixing time is not fixed, will lead to the color masterbatch raw material in the mixing tank uneven distribution or segregation stratification;

4. Prevent static electricity: plastic in the mixing process due to friction generated static electricity, resulting in uneven distribution;

5. Stoppage: it is necessary to empty the raw materials in the barrel and reduce the temperature of the barrel to avoid the thermal oxidation and decomposition of the raw materials for a long time, causing the film to turn yellow and produce black spots;

6. Material selection: try not to choose raw materials containing BHT antioxidants, because blocked phenolic antioxidants in high temperature, high humidity, there are oxides in the alkaline environment, prone to automatic oxidation reaction, resulting in plastic surface discoloration (generally pink or light yellow);

7. Storage: Store the film masterbatch in a dry, ventilated and clean environment with an ambient temperature below 50 ° C to avoid pollution.

If you need to use masterbatch coloring in the production process of film products, then we need to comply with the above precautions!
