Double Sided Transfer Tape
Transfer tape is tailored for uniting two entities that are then once stuck - not meant to come apart again. Very aggressive adhesive, small width rolls.
Double sided transfer tape is used in situations where once the connecting objects are fixed or stuck together, they are not intended to come apart. Aggressive adhesive that can be used on a range of materials including: metals, plastics, woods and paper. Objects such as books or folders would be a prime example of where double sided transfer tape would be used as it would totally seal the pieces of paper together without leaving any visible evidence that the pieces were separate to begin with. Could be used in many other situations where the use of glue may be impractical.
