Abstract: A polymer film for storing fruits and vegetables includes a first polymer resin material, a second polymer resin material, and an inorganic nano powder material. The first polymer resin material has a first molecular weight. The second polymer resin material has a second molecular weight. The first molecular weight is less than the second molecular weight. The first polymer resin material and the second polymer resin material are blended with each other according to a predetermined weight ratio so that the polymer film has a gas penetration rate between 3.5 g/m2/day to 35 g/m2/day. The inorganic nano powder material includes zinc oxide (ZnO). The inorganic nano powder material is dispersed in the first polymer resin material and the second polymer resin material in a plurality of granular forms, and an average particle size of the inorganic nano powder material is between 50 nm and 200 nm.

Abstract: A heat-insulating transparent PVC sheet is formed from a PVC substrate having a thickness of 0.02-2.0 mm and contains heat-insulation pastes evenly distributed over the PVC substrate, since the heat-insulation paste contains an essential component of wolfram cesium powder (WCs) with a chemical formula of CsXNYWO3-ZClC and having a particle size of 0.005-2 μm, the heat-insulating transparent PVC sheet has an excellent weatherability, and particularly before and after tested in 300-hour service life in line with ASTM G-154 specification, has a physical property of weatherability decay rate (%) small than 4%.
