The PH7-70 is a white, single sided acid free (pH7- neutral) adhesive paper tape. It is a self-adhesive tape and has a high initial grab, with excellent temperature resistance. This has previously not always been achieved by acid free tapes. PH7–70 acid free tape uses a water based acrylic adhesive that does not yellow as it ages.

Ideal for hinging artwork and prints to picture mounts, other applications include book repair and conservation, dust sealing and other archival/conservation uses.
