The above data can only be regarded as typical physical properties, not guarantee values.Application Type of BOA,TOA-C and OA-1 can be applied in the process of printing and laminating, TOA-S and OA-2 in laminating without printing. BOPA films are humidity sensitive, which may cause printing or laminating defect in high humidity absorption and impacting the usage satisfaction, thence, users are recommended to process the unpacked film rolls quickly, pack the printed films with aluminum metallized films, and laminate them without delay. To obtain products’ good quality, BOPA is not suggested being processed in the humidity over 75%RH.
