Filmoplast P1 tape

In respect of Gary Saretzky's enquiry about Filmoplast P1 this
tinted self adhesive tape product was discontinued in Europe a
little over 2 years ago after the discovery that tea was the
principal component behind the stained finish.

What drew us to the composition query in the first place was that
selective tests showed a marginal drop in pH in the tinted products
as against the conventional versions.

My understanding from sources at the time at Neschen's UK operation
was that the company had no plans to reintroduce the products using
alternative staining means. This may well have been due in part also
to the fact that neither the P1 or P91 versions had gained the same
commercial respect as the company's other approved archival
products.

Whether one likes the idea of a pressure sensitive adhesive product
(archival or otherwise) or not, the fact remains that both
Filmoplast P and Filmoplast P90 continue to hold the title of market
leaders in the library field.

For some ephemeral material both tapes provide a beneficial service
and unlike most of the generally used commercial self-adhesive tapes
they are in the main part removable using water, a spirit based
solvent or a combination of both.
