    摘要: Film structures made from a polymeric blend comprising an ethylene/carbon monoxide (ECO) copolymer and an olefinic, particularly an ethylenic, polymer, e.g., LDPE, exhibit not only photodegradation, but also desirable tensile and dart properties. In one embodiment the film structure is a monolayer in which ECO copolymer comprises at least 40 weight percent with the remainder of the structure comprising at least one of LDPE, LLDPE and HDPE.
