0 a light, usually thin, soft plastic, often used for making bags or for keeping things dry or fresh:
These were placed randomly in a tunnel covered with a black polyethylene mesh and equipped with a microsprinkler system controlled by an electronic humidity sensor.
Also, opaque polyethylene film does not effectively suppress nutsedge unless a soil fumigant has been applied.
The trap interior contains an 18 cm polyethylene funnel which is suspended beneath the drainpipe by four chains.
However, the use of polyethylene mulch has several limitations and disadvantages.
In crops which experienced heavy rain, application of a synthetic fruit-set hormone enhanced fruit numbers as did the simple transparent polyethylene rain shelters.
Each stem was carefully covered with a polyethylene bag before it was cut to avoid adult bugs from escaping.
For chemical analysis, the soil was air dried and stored in polyethylene bags at room temperature.
Direct measurement of polyethylene glycol induced depletion attraction between lipid bilayers.
