This archival tape is used extensively in libraries and archives for mending tears in paper.
An archival quality pressure sensitive, thin, transparent paper tape made from a special acid and wood free paper and long lasting non yellowing adhesive. Once burnished down it virtually disappears into the paper, leaving a mend that both looks and feels like the original page. Both the adhesive and paper are buffered with Calcium Carbonate making the tape slightly alkaline (pH ~9.2) to counter any acids in the paper it is applied to.
We recommend that the tape be burnished upon application with a bone folder to achieve the optimum in transparency. Suitable for mending tears in pages, hinging light weight photographs and prints and reinforcing folds in maps and other papers. Can be used as for labels, and will stick to Mylar.
Paper weight is 20gsm, with a solvent, acid, and phthalate-free non-yellowing archival adhesive which will remain permanently elastic and not dry out.
This product has passed the Photo Activity Test (PAT) ISO 18916.
