ALDYNE™: surface treatment by atmospheric plasma for plastic films converting industry

Study of Surface Properties of Polyolefins Modified by Corona Discharge Plasma

“…The lowering of the surface energy of PO can be accomplished through reorientation of functional polar groups towards the bulk of the polymer, as well as through diffusion of low‐molecular weight additives, or bloomers towards the surface of PO. The improving of the strength of adhesion joints with PO represents a complex phenomenon, in which the elimination of layers of low‐molecular substances from polymer surface plays an important role,58,60 the low adhesive properties of PO are ascribed to its non‐polar character and to low values of the surface energy. The chemical changes, which result in the increase of the polarity and of the surface energy, are considered as the most important in the modification of PO 44.…”

Improving mechanical performance of thermoplastic adhesion joints by atmospheric plasma

“…These are characterized by exposition of the polymer surface to the action of different radiations such as ultraviolet light, γ-radiation, β-radiation, laser, non-thermal plasmas, etc. In the last years, atmospheric plasma has become an interesting alternative to chemical processes since it allows surface modification in a dry process, which leads to high environmental efficiency [13][14][15][16]. The action of the plasma gas can promote surface abrasion or etching due to removal of low molecular weight oxidized material (LMWOM) and this can produce changes in surface topography [17].…”

Surface Treatment of Polytetrafluoroethylene for Adhesion

“…39 Plasma treatment has been applied 40,41 to textiles with the objectives of increasing or decreasing hydrophilicity and improving dyability or printability of cotton, wool, and synthetic polymers. Air is substituted with a nitrogen-based gaseous mixture in the discharge area.…”
