A type of multipurpose tape that only has very mild adhesion until you heat it or compress it, something you do to change the amount of adhesion.. The problem with a lot of heavy duty tapes are that if you aren't careful they stick to themselves and you end up having to throw it away.

Mind reading tape! Man, that is cool! |

I understand the heating . . . not the compression part, though. |

erm... that would be Pressure Sensitive Tape. You press it hard and it sticks hard. See link. |

Where I work (in a library) we use a special type of sticky backed plastic <obligatory Blue Peter flashback> </obligatory Blue Peter flashback> to cover books which is only slightly adhesive at first to enable repositioning, but which bonds permanently over time (it takes about 1/2 an hour to stick fast). Perhaps this could be produced in thin strips. |

The basis for heat - and pressure sensitive adhesives which may be incorporated into tapes is that of micro-encapsulation. Very small droplets of one component is encapsulated and dispersed within a matrix of the other component. This is the basis of the adhesives of the pressure sensitive type. |

A "glue stick" which looks like a lipstick and is applied the same way (to paper you wish to stick, not the lips) is a microencapsulated product. |

It is an old technique, old enough to have textbooks written on the subject, and the patents have probably expired. |
