李：在圍巾發(fā)運之前，先將其包在一個塑料薄膜袋中，然后用繩子把20條扎起來做一捆。
Natural grass mulch was less effective than straw mulch, but more effective than plastic-film mulch and clean tillage in soil cooling.
自然生草在降溫方面的效果不如覆蓋稻草處理明顯，但優(yōu)于覆蓋地膜和清耕（對照）。
Considering the positive effects of plastic-film mulch and negative impacts of plastic film residue synthetically, the evaluation model of effect of plastic-film mulch on crop yield was constructed.
綜合考慮地膜覆蓋技術對農作物產量的正面效應和地膜殘留對農作物產量的負面影響，構建了地膜覆蓋技術對農作物產量影響的評價模型，并以湖北省為例進行了評價。

HSS' transducer is a 28-micron-thick plastic film that flutters when exposed to an electric field (because it is "piezoelectric").
FORBES: Technology
Zach McCue of Clean Ocean Action, a coalition of more than 130 environmental organizations in New Jersey and New York, said the manufacture of thin-film plastic bags consumes millions of trees and barrels of oil, takes up space in landfills for a long time and is harmful to marine life, especially birds and sea turtles that ingest the bags, or pieces of bags, or get entangled in them.

塑料地膜
The results demonstrate that high concentrations of plastic film mulch had toxicity on wheat in accordance with variations in these physiological indexes of wheat.
結果表明,高質量分數(shù)塑料地膜的處理會對小麥早期幼苗的抗氧化酶系統(tǒng)產生毒害作用。
塑料薄膜
In some range the temperature keeping effect by non-woven fabrics was closed to that by plastic film. It also decreased the relative humidity in seedbed,which could approach to that in outside.
結果表明,相對于塑料薄膜,無紡布可有效調控床內的溫度,使溫度變化相對平緩,減少障礙性高溫出現(xiàn)的機率,減少煉苗的次數(shù),在一定范圍內其保溫效果與塑料薄膜相近;還可降低床內的相對濕度,使之與外界接近。
