TS stocks both packing tape (under the workroom counter) and book tape (in the processing supplies cupboard). When you’re considering which tape to use, keep in mind the cost of book tape ($.63 per yard) vs. packing tape ($.05 per yard).
Book tape
is thick and acid-free. It’s a good choice for mending library materials as it won’t yellow over time.
Packing tape isn’t quite as thick, but it’s the right choice for packing boxes and your other wide-tape adhesive needs.
