摘要:
A polyolefin resin covering film having a first layer of a polyolefin resin and second and third layers which are provided on respective sides of the first layer and made of a polyolefin resin containing 20 wt. % or less of a polar group-containing vinyl monomer, in which the polyolefin resin covering film contains 6 to 50 wt. % of a IR absorber based on the weight of the covering film, and has a IR absorbance of 70 to 85 % at 27°C, which covering film is preferably used as a covering film of a green house or tunnel for protected horticulture to raise a strong-light produce.
摘要:
A polyolefin resin composition containing a polyolefin resin, 0.03 to 60 wt. % of a double hydroxide comprising lithium, aluminum and at least one element selected from the group consisting of alkaline earth elements, transition metals, Zn and Si, and 0.02 to 5 wt. % of a hindered amine compound, which has good weather resistance and useful as a material for the production of films, in particular, agricultural films.
