Abstract
A label having a thermoplastic polymer film and an ink layer formed on at least one surface thereof, the ink layer being removable in alkaline hot water, can easily be recycled after separated or without being separated from the bottle into polymer pellets with improved purity. The recycled polymer pellets are extremely suitable for the effective use of resources because they contain substantially no ink and can therefore find various applications.
