2 product ranges 1. S-Class (Sustainable Range) 2. R-Class (recycled Range
Sometimes confused with synthetic paper, Rockstock is neither synthetic nor pulp or fibre based and is termed "Rich Mineral Paper". Rockstock has qualities of both pulp and synthetic papers, but more importantly it is much more environmentaly friendly than either of the two. The printing qualities and exclusive feel make Rockstock a paper product not seen the likes of previously.
Due to its absorbency attributes, it has superior handling and printing qualities.
It is also water, mist, grease, anti-moth and insect proof*, freezer grade, and can be heat sealed(certain products apply).
As it is food grade*, Rockstock is suitable for thermoforming food trays, containers and in mould labelling.
Rockstock has unusual physical strength and high fold durability.
In addition of up to 81% ground-up mineral waste or CaC03, Rockstock contains a small amount of a non toxic photodegradable PE resin.
