PP
Why? Typical rigid containers have stiff walls, are not flexible at all when handled. They usually have simple curves only. The key requirement for rigid film materials is to integrate seamlessly on this substrate and provide optimal no-label look.
Label must be sized so it can be placed between the curves at the top and bottom of the bottle in order to avoid long-term lifting and darting. Rigid films will not conform to curvatures.
For this container type, we would recommend the following materials: VANISH™, PP Clear or PP White.
