| 摘要 |
<p>The invention relates to a method for producing a laminate comprising at least two polymer layers, a layer (A) and a layer (B), which are fixed to each other by at least one aqueous-type adhesive polymer material layer (C). Said method is characterised in that: (a) it optionally consists of a step of pre-cleaning substrate layer (A) and/or substrate layer (B), by oxidising or reducing continuous atmospheric cold plasma processing pre-cleaning; (b) the plasma is either (i) oxidising or reducing when the layer is a polymer layer having a shore D of strictly between 35 and 60 or when the layer is a polymer layer having a shore D > or = 60 and the distance between the plasma source and the surface of the layer to be activated is < or = 3 cm, and (ii) the plasma is reducing when the layer is a polymer layer having a shore D > or = 60 and the distance between the plasma source and the surface of the layer to be activated is > 3 cm, substrate layers (A) and (B) being identical or different and formed by non-exudant polymers.</p> |
