Package & Storage
* EVA film roll is wrapped with PE film, sealed by Aluminum foil bag, and packed into Carton
box.No more than two-layers piling-up is permitted.

* Stored in ventilated environment at less than 30°C temperature and 60% humidity;
Avoid direct exposure to heat, light, rain, heavy stress or impaction by hard objects.

* Shelf life: suggest to using up the EVA film within 3 months to get the best function. After
opening package, keep the balance in ventilated environment at less than 30°C temperature
and repacked, and use it up within 2 days.
