Rolls are each one protected by a bubble LDPE film, packed suspended on plastic shoulders and delivered in wooden cranes suitably treated, stamped and certified for sanitation.
MANIPULATION
The ETFECT sheet shall be carefully moved, not dragged on the round to avoid scratches and loss of the printing. Take care that fast movements can generate electrostatic charges on the material surface which can held to printing losses and to sparks.
INSTALLATION
As far as the mechanical resistance is concerned, the installation shall be made in order to avoid possible alternate swinging induced by wind which can produce cracks and fragile breaks on the bending zones.
INSPECTION CERTIFICATE
Each production lot will be inspected in internal laboratory for:
- Mechanical uniaxial characteristics by means of a Zwick&Roell dynamometer
- Optical and radiometric properties by means of a Perkin Elmer spectrophotometer.
- Each roll can be provided with the map of eventual defects exceeding 0,8 sqmm.
- Each roll can be provided with the synoptic of thickness measure and tolerance
WARRANTIES
ETFECT film exposure life to solar radiation is still unknown, as the first installations of middle 80’s are still existing, so a real warranty cannot be given, but an expected life of more than 20 years is considered realistic.
