BIODEGRADABLE MATERIAL FOR AN ADVERTISEMENT, AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a material for an advertisement that comprises a biodegradable film laminate in which a surface film layer, an adhesive layer, and a release layer are sequentially laminated, wherein said surface film layer consists of 5 to 40 wt % of a polylactic acid-based polymer and 95 to 60 wt % of aliphatic polyester. The invention also relates to a preparation method thereof. The material for an advertisement comprising the biodegradable film layer according to the present invention can be easily used for manufacturing a printed advertisement which is used for a short period of time and discarded. The material of the present invention exhibits a biodegradability in soil of 60% or more, as compared to cellulose, within 6 months of being discarded. Therefore, the material of the present invention discharges no noxious environmental hormones produced by conventional polyvinylchloride (PVC), thus protecting the natural environment and exhibiting a high level of friendliness to the human body and to the global environment.
