LAMINATED FUNCTIONAL FILM FOR SURFACE PROTECTION ENABLING THE FILM TO BE EASILY APPLIED ON OR REMOVED FROM THE ADHERED OBJECT OVER A WIDE RANGE OF TEMPERATURE

摘要

PURPOSE: A laminated functional film for protecting a surface of an adhered object is provided to achieve a self-adhesive property without the use of an adhesive agent, to exhibit little change over time in physical properties even at a temperature change, to allow the film to be easily applied on or removed from the adhered object over a wide range of temperature, and to be easily fed apiece from a stack. CONSTITUTION: The laminated functional film comprises: an inner layer directly contacting the adhered object and formed of a mixture containing 100 wt% of linear low density polyethylene(LLDPE) and 100 wt% of low density reinforced olefin; an intermediate layer formed of a mixture of 95 to 99.5 wt% of middle density polyethylene(MDPE) or high density polyethylene(HDPE) and a 0.5 to 5 wt% of a conductive polymer; and an outer layer formed of 100 wt% of low density polyethylene(LDPE), the respective layer materials being extruded in a discharge ratio of 3:4:3 in order to fabricate the film to a predetermined thickness. To avoid occurrence of blocking or to allow stacked films to be fed apiece, size-adjustable cellulose or fluff is optionally applied on the outer layer before the outer layer is solidified.
