Packaging & Availability
- Packaging
- Bobbins are individually wrapped with stretched plastic fi lm for protection, improved handling and to allow optimum transfer from bobbin to bobbin. Nominal weights for R and C bobbins are respectively 21 and 25 kg.
- Two pallet confi gurations are available:- Bulk Pack: standard packaging, consists of individual bobbins.- Creel Pack: bobbins are connected together for continuous unwinding and no bobbins handling for operators.
Storage & Handling
- Storage
Storage in a cool and dry warehouse into the original packaging is formally recommended. More precisely ideal storage condi-tions are a temperature between 15°C and 35°C and a relative humidity comprised between 35% and 75%. If these conditions are maintained, the glass fi bre product should not undergo signifi cant changes when stored for extended periods of time. It is also strongly recommended to condition it in the workshop for at least 24 hours before use to prevent condensation.For an optimal processing it is recommended to use the pro-duct in ambient conditions (20°C-23°C and a relative humidity of 60%-65%).
