Polymer Type |
| Thermoplastic |
Advantages |
| Superior clarity. Excellent barrier properties. Suitable for food packaging applications. Recyclable. |
Disadvantages |
| Very susceptible to heat degradation. Excessive shear heat should be avoided - therefore low screw speed and back pressure required. For optimum clarity, mould temperature should be kept between 10°-50°C ( 50°-120°F ). |
