| 摘要 |
<p>The invention is a new covering film for use in agriculture, consisting of one or more layers, having at least one layer comprising polyamide, be it homopolymer or copolymer. At least one layer comprises only polyamide. The polymers that make up the film layer/s can be homogeneous or heterogeneous and can be characterised by affinity or non-affinity of their polymeric structures from a molecular point of view, as well as by concentrations varying from 1 to 100%. It is possible to include additives, like slipping additives, antistatic agents, anti-drip agents, UV stabilizers, mineral fillers, bonding agents for adjacent layers, nucleant agents, crosslinking agents, nanocomposite additives, hollow and solid microspheres in glass, silica, zeolite, ceramic or other materials.</p> |
