Abstract
A polymer film, comprising at least one active layer made of a composition containing a polymeric substrate comprising at least one of the polyolefin polymer and polyamide 6, and a coniferous resin acid(s) dispersed in the polymeric substrate.
Claims14
An agricultural film comprising at least one active layer made of a composition containing:
- (a) a polymeric substrate comprising polyolefin polymer,
- (b) at least one coniferous resin acid dispersed in the polymeric substrate, and
- (c) one or more further polymer(s) for controlling the release rate of at least one coniferous resin acid(s), the one or more further polymer(s) selected from:
- (i) polyamide,
- (ii) inherently dissipative polymer (IDP),
- (iii) polyethylene-block-amide (PEBA), and
- (iv) polyether-polyamide block copolymer, wherein
- the amount of the one or more further polymer is 1%-90%, by mass, based on the mass of the at least one active layer, for covering silage.
