Durability of mono-layer versus tri-layers LDPE films used as greenhouse cover: Comparative study
The mono-layer low density polyethylene LDPE films are often used as a cover for the greenhouses. Recently, there are few attempts for utilizing the tri-layers LDPE films as substitute for mono-layer film. The degradation and fracture behaviour with regard to abrasion of that new generation of polym...

The degradation and fracture behaviour with regard to abrasion of that new generation of polymeric greenhouse covers presenting a sandwich structure made of three layers of LDPE have been studied and compared with that obtained for monolayer film often used in North Africa for plasticulture devices. Surface analysis and mechanical properties have been analysed on samples having undergone natural conditions in the north of Africa (Algeria).
