The invention belongs to the technical fields of agripast film preparation, and in particular to a kind of micro-porous permeable plastic foil and preparation method for urea fertilizer packaging.A kind of micro-porous permeable plastic foil and preparation method thereof for urea fertilizer packaging of the present invention, by thering is foaming agent and the strong mixing inorganic filler for absorbing material by microwave application to be added in resin load, sawdust generates microdefect under microwave radiation induction, by contacting, heat is transmitted and microwave energy input action is in foaming agent, and microdefect increases because of foaming, become larger, therefore micro-porous permeable effect is realized, the more conventional film of its air permeability effect is more preferable, it can continue the flatulence for generating inside discharge, and without carrying out MULTILAYER COMPOSITE, reduce cost, packaging bag excellent in mechanical performance, service life is longer. |
