Although the adhesive force of the ink is increased, the process is increased, the yield is affected, and the cost is not reduced.
CN107459636a uses terephthalic acid, ethylene glycol, neopentyl glycol and polytetramethylene ether glycol to copolymerize and prepare shrink films, but the process of film preparation does not use a three layer coextrusion approach and does not demonstrate its improvement in UV ink adhesion.
