Abstract
The present invention is a cold seal composition having certain rheological properties. The composition comprises from about 10 wt-% to 100 wt-% of at least one homogeneous ethylene/.alpha.-olefin interpolymers. The novel adhesive compositions of the present invention may be coated onto a variety of substrates, resist blocking upon being supplied as a roll-good, and exhibit a wide range of bond strengths, amenable to a variety of cold seal bonding applications.
