“Stone paper”的意思、由来-开放百科全书

Stone paper, also known as limestone paper, rock paper, bio-plastic paper, mineral paper and rich mineral paper, is a type of strong and durable paper-like material manufactured from calcium carbonate bonded with small amount of resin high-density polyethylene (HDPE). It is used for stationery, leaflets, posters, books, magazines, bags, packaging, wallpaper, adhesives, tags, in-mould labels, plates, trays, containers, and maps among other uses.

History

The process for creating stone paper was first developed by Taiwan Lung Meng Tech Co. in Taiwan during the late 1990s,^[1]

Properties

Stone paper has a density range of 1.0-1.6g/cm³, which is equal to, or slightly higher than ordinary paper, and a texture somewhat like that of the outer membrane of a boiled egg. It may be recycled with Number 2 plastics or remade into rich mineral paper again, and is not biodegradable but is photo-degradable and compostible under commercial conditions.{{citation needed|date=August 2018}} It is suitable for stationery, bags, packaging, adhesives, greaseproof paper, wrappers, containers and many other applications.

The {{definition span|RPD and RBD papers|explain=What're RBD & RPD?|date=December 2015}} have a number of advantages over traditional paper made from wood pulp. Stone paper collects no static charge, is acid-free with a neutral pH, has no grain, is water, grease, and insect resistant, and tears with difficulty due to a latex-like texture.

Because it is not made from fibers, stone paper possesses a smoother surface than most traditional paper products, eliminating the need for a coating or lamination. The source of the calcium carbonate is waste material collected from marble quarries and offcuts which are ground and reduced to fine white calcium carbonate powder. The production of stone paper uses no water, acid, bleach or optical brighteners. It can be recycled endlessly, but only if recycled separately at civic amenity sites^[2]^[3]

Stone paper is compatible with inkjet or solid ink printers e.g. Offset, Letterpress, gravure, flexographic, but does not respond well to very high temperature laser printers.^[4]
