ABSTRACT:
This invention presents a series of synthetic based cold seal adhesives which are capable of forming a strong bond at room temperature, yet which may be reeled up without blocking and stored for extended periods of time. Such adhesives can be used in place of the natural rubber based cold seal adhesives currently used, and thus, can be employed in any packaging application where cold seal properties are desirable.
