Essential Advantages
Microwavability
Suntec™ S films are generally superior in heat resistance to other polyolefine heat-shrink films, which tend to deform and melt if subjected to microwaving together with the wrapped product.
Suntec™ S grade M710S, in particular, resists film interface melting and re-fusion under re-heating and microwaving, and provides the optimum in microwavability.
Note!
For any microwaving of an Suntec™ S-wrapped product, avoid heating the film above 100 °C, and perform advance trials to ensure the absence of pinhole formation or other sign of film softening or deformation.
With Suntec™ S, secondary stress shrinkage under microwaving is low, with little
or no resultant deformation of the plastic container.
