ABSTRACT:
In one embodiment, the invention relates to an ink-imprinted and reusable multilayer cling film of at least one layer for use in combination with a substrate having a rigid smooth surface comprising a non-vinyl flexible polymer cling film which has two smooth surfaces, is substantially free of added plasticizer and provides a 180.degree. peel force after application to glass of from about 30 to about 2500 gms after aging in a 140.degree. F. oven for 72 hours.
In another embodiment, the invention relates to an ink-printed and reusable multilayer cling film of at least two layers which can cling to substrates having a rigid smooth surface without the use of an adhesive material. For example, such multilayer cling film may comprise: (A) a first layer of at least one thermoplastic polymer film having an ink-imprinted upper surface and a smooth lower surface; and (B) a second layer which is a polymeric cling film having an upper surface and a lower surface and comprising at least one non-vinyl thermoplastic elastomer wherein the upper surface of the second layer is in contact with and adhered to the lower surface of the first layer.
In yet another embodiment, the invention relates to an article comprising a substrate having a rigid smooth surface and an ink-imprinted flexible polymeric cling film of at least two layers which are affixed to the smooth surface of the substrate without adhesive whereby the cling film is removably adhered to the substrate.
