A non-wicking grade of heavy-duty, recyclable paper is manufactured for wrapping tin plate coils and sheets. The technical requirements of this material are demanding, for it needs to be waterproof, rust inhibiting and able to physically protect the wrapped coils and sheets.
The wrapping paper is used to provide protection to the steel plates during transportation and storage. As well as a non-wicking, water-resistant finish, the paper also receives a vapour phase inhibitor coating to provide corrosion protection for the sheet steel.
A laminated strengthened paper is manufactured where water resistance is imparted by a combined application of Mystolene PS at the wet-end and a size press application of Mystolene MAS. The wrapper combines Mystolene treated paper and a reinforced plastic film, which after use can be easily separated for recycling.
