The reasons and the solutions of poor transparency of composite packaging film

Reason:

1. The surface temperature of the cooling roller is too high

2. The surface is too rough

3. The pressure of compound roller is insufficient

4. The initial adhesive force of AC agent is poor.

Solution:

1. Decreasing temperature properly.

2. Replace with a clean cooling roll

3. Increase compound pressure

4. Use a high viscosity AC agent

5. Adjust the extrusion process parameters
