    摘要: Disclosed in this invention is a composite stretch film for agricultural use, formed by bonding two stretch films together with an adhesive through hot rolling or UV curing such that primary stretch directions thereof cross each other. Compared to the existing single-layer agricultural films having the same thickness, the composite stretch film for agricultural use of the present invention is significantly improved not only in transverse and longitudinal tensile strength but also in transverse and longitudinal tear strength. Therefore, it is able to meet the requirements for use in agriculture with a lesser thickness and hence reduce the use cost. In particular, in case of the composite stretch film being made of a polyester material, it further offers the advantages such as highlight transmittance which changes mildly with time, better thermal insulation properties and better humidity-regulating capabilities. In particular, in case of it being made of a degradable polyester materials, it will further offer profoundly significant benefits in terms of energy saving and environmental protection.
