Patent ID: 7494707

Claim:
A splicing tape for flying splice for joining the end of an old, outgoing reel to the start of a new reel to be introduced to replace it, said splicing tape having an adhesive coated on only one side of a backing, said adhesive comprising at least a) from 40-70 percent by weight of polyisobutylene and b) from 30-50 percent by weight of at least one tackifying resin, wherein c) the molecular weight distribution, defined as the plot of frequency over the molecular weight of the polyisobutylene features two relative maxima, d) one relative maxima between a weight average molecular weight M w of 40,000 g/mol and a weight average molecular weight M w of 200,000 g/mol and e) a second relative maxima between a weight average molecular weight M w of 1.0×10 6 g/mol and a weight average molecular weight M w of 3.5×10 6 g/mol, and said splicing tape having a cleavable system on a side of the backing opposite the adhesive.
