Methods of adhering graphic film on an irregular substrate are disclosed. The methods includes providing a polymer film composite having two or more layers with at least one layer having a glass transition temperature of at least about 40°C, the polymer film composite having a first side and a second side, and an adhesive layer disposed on the second side. Then the method includes, positioning the adhesive layer against the irregular substrate, heating the polymer film composite, and pressing the heated polymer film against the irregular substrate.
la présente invention concerne des procédés d'adhésion de film graphique sur un substrat irrégulier. Ces procédés consistent à prendre un composite de film polymère possédant au moins deux couches dont une couche au moins possède une température de transition vitreuse d'au moins environ 40 C, ce composite de film polymère possédant une première face et une seconde face et une couche d'adhésif placée sur la seconde face. Puis ce procédé consiste à positionner la couche d'adhésif contre le substrat irrégulier, à chauffer le composite de film polymère et à presser le film polymère chauffé contre le substrat irrégulier.
