KS18 Clamshell box PREMIUM
A tightly closing premium clamshell box; a more elaborate version of the known "Solander Box". Manufactured whilst using the finest book binding methods, this classical drop-back clamshell box is produced from solid conservation board with a complete fabric lining. Special emphasis has been given to ageing resistant and environmentally compatible (less-polluting) materials. Delivery assembled and upright.
These boxes are most suitable to store and preserve works of art, books, manuscripts, prints and printed matter, drawings and photographs in a protected environment. Manufactured whilst using the finest bookbinding methods, this classical premium quality, tightly closing, acid-free clamshell cassette is available in any individual size.
The upper and lower cabinets of the box are made of KLUG conservation board of 2 mm thickness, are cut to mitre and glued together. The book cover is made of 1.5 mm conservation board. The cover lining fabric is made of natural linen „Lino Auster 405“. The inner liner consists of 0.5 mm natural white conservation board, available either with or without alcaline (carbonate) buffer. The dispersion glue used for manufacturing the clamshell cassette is free of plasticizers.
The boxes are delivered assembled and upright.
State-of-the-art, computer-aided manufacturing methods enable us to produce clamshell boxes accurate to the millimetre. We deliver from single unit orders up to serial unit orders
This traditional, premium quality, bookbinding clamshell cassette is made from solid board material and meets all the requirements for long-term, permanent and protective archival storage. board materials used are ageing resistant in accordance with the technological requirements of ISO 9706:2010, ISO 16245:2012, ANSI/NISO Z.39.48:1992 and DIN 6738:2007 standards, and PAT tested in accordance with ISO 18916:2007.
The linen fabric used for lining is not dyed, to avoid colour pigments bleeding in the case of water damage. The paper lamination on the cover fabric lining is pH-neutral and impregnated with a starch derivative glue. The slightly alkaline PVAc dispersion glue used to gum the lamination paper with the cover lining fabric is free of softeners and plasticizers.
The dispersion glue used for the board material is based on an ethylene venyl acetate copolymer (EVA), is pH-neutral and free of plasticizers
