Abstract
Few attempts are available in the literature on utilising the trilayer low density polyethylene (LDPE) film as new generation of greenhouse cover to substitute the monolayer film that is often used. This paper investigates and compares the degradation behaviour and durability of both covers. The covers are exposed to 7 months of natural withering. The results revealed that the degradation resistance of trilayer film is better than the monolayer film in terms of their mechanical and optical properties. The service lifespan, based on 50% reduction in the property criterion, of the trilayer film is found to be double the service lifespan of the monolayer film.
