Abstract
PURPOSE:To obtain a packaging material, having excellent after ripening action, preventing action on dew condensation and absorbing action on stench components and improved transparency, and useful for retaining freshness of vegetables and fruits, by using a specific aluminosilicate as the freshness retaining agent for the packaging material. CONSTITUTION:An aluminosilicate having a chemical composition expressed by 10-35wt.% oxide of the formula M2/mO (M is group I or II metal of the periodic table; m is the valence of the metal M), 35-70wt.% SiO2, 15-35wt.% Al2O3 and 0-25wt.% H2O on the basis of oxide weight and X-ray diffraction pattern unique to X- or Y-type zeolite, <=0.2-3mum primary particle diameter and <=5mum secondary particle diameter measured under an electron microscope, 1.43-1.54 refractive index and >=20mg/l ethylene adsorptivity is used as a freshness retaining agent. A polymer, e.g. polyethylene, is then blended with 0.2-15wt.%, especially about 2-8wt.% above-mentioned aluminosilicate and the resultant blend is subsequently molded into films, trays, etc.
