Shrink wrap label coating to facilitate recycling
The present invention discloses a method of enabling the easy separation of labels, including wrap around labels and sleeve labels, particularly shrink sleeve labels, from containers during recycling through the use of a specially formulated coating to be applied in the seam area. The coatings ensure proper bonding, and shrink properties, of the labels, and have been designed to help de-bonding of the seam in a hot caustic wash step, or a solvent wash step. The method does not rely on floatation separation and therefore may be applied to any container/label material combination regardless of their specific gravity differences.

Coating liquid, coating film, and composite material
There is provided a coating liquid capable of forming a coating film that is excellent in adhesiveness to the surface of a base material such as a metal, glass, or a resin even though the coating film contains PVDF which exhibits a remarkable non-tackiness and that can exhibit various desired functionalities such as non-tackiness, an antifouling property, chemical resistance, a sliding property, water repellency, electrical conductivity, an antifungal/antimicrobial property, and a deodorizing property. The coating liquid contains a polar solvent such as N,N-dimethylformamide or N-methyl-2-pyrrolidone, a hydrophilic polymer such as a chitosan derivative or a cellulose derivative, and polyvinylidene fluoride.
