Storage & Handling
- Storage
All films should be stored in a dry environment at a temperature under 30° C. If properly stored, the film will maintain consistent performance over a period of up to 6 months from the date of production and should be converted prior to this time. A prolonged period of storage may cause problems of thickness profile and blocking on account of the elastic memory of thermoplastic film. It is a fact that polypropylene films age with time and will exhibit deterioration in the wetting tension levels. For this reason it is recommended that film stocks are evaluated for ink adhesion prior to printing and if necessary retreated during conversion process to ensure optimal adhesion or inks and adhesives. It is also advisable to allow the film to reach room temperature at least 24 hours prior to use. Sealing9 properties of film deteriorate when corona treatment is present. Aways check the treated side when using the film.
