As to our agreement to do a testing with IPSUN base paper 210 gsm but it seem difficult to have it for this project because they have much increased their selling price to customers. As a result, currently mill have contacted SUNPAPER, as an option, who is the associated mill of IPSUN Group to work with them. Further, They have ordered the paperboard for their trial. If the paperboard is workable, then mill will consider it to replace IPSUN paperboard for your testing. Please kindly consider whether or not SUNPAPER can be considered and accept also please kindly feel free to let us know your comments if any.
