Our range of Special Papers include Kraft Union and VCI Anti-Rust papers. Our Kraft Union paper is a waterproof paper. It is constructed with a layer of bitumen sandwiched between two layers of kraft paper. This therefore creates a tough paper, which is ideal for lining packing cases. In addition to this, if offers excellent moisture protection. 2 sizes are available, both at 120GSM. Our VCI Anti-Rust paper is pure kraft paper impregnated with an active inhibitor. This therefore protects ferrous metals from rusting or tarnishing during transportation and storage. 2 sizes are available. In addition to 50GSM, a 55GSM paper is also available. Ordering your Special Papers from Springpack really couldn't be easier! Don't forget, we deliver the next working day if your order is placed before 3:30pm.
