Problems solved by technology

[0009] However, the conventional perforated films have contradictory problems, that is, in order to achieve waterproof and heat retention, it is necessary to reduce the size of the holes, but this will cause the disadvantage of not being able to breathe fully, but if the size of the air holes is increased to ensure air permeability , there will be problems that reduce the waterproof and insect-proof effect and the heat preservation effect

Abstract

To prepare an agricultural film used for lining or outer covering for greenhouse cultivation, tunnel cultivation, or the like, and having excellent anti-fogging properties and moisture permeability. This agricultural film is characterized as having a plurality of micropores obtained by perforation processing of a thermoplastic resin film with a needle having spiny projections. The thermoplastic resin film having the plurality of micropores is characterized in that the shape of the micropores has a spiny form having the spiny parts. The film having the plurality of the micropores is characterized in that the total light transmittance of the film at 555 nm is preferably >=70%.

Description

technical field [0001] The present invention relates to an agricultural film for inner or outer covering of cultivation in plastic sheds and plastic tunnels, and in particular to an agricultural film excellent in anti-fog and moisture permeability. Background technique [0002] In the past, the method of accelerating the cultivation of crops was mainly to cultivate plants under the cover of agricultural films such as vinyl chloride resin films or olefin resin films, that is, cultivation in plastic sheds and cultivation in plastic tunnels. [0003] In such plastic shed cultivation and plastic tunnel cultivation, etc., the temperature and humidity in the plastic shed and plastic tunnel have a great influence on the growth of crops, so it is necessary to adjust it according to the climate. [0004] Especially in the cultivation of large-scale plastic greenhouses in recent years, in addition to the agricultural film for outer laying that is fixedly spread on the frame of the gre...
