- Abstract
A type of blending films ba,sed on poly (butylene adipate-arterephthalate) (PBAT) and poly(lactic-fo-butane-diol itaconate) (PLBI) were prepared at different ma,s,s ratio,s through melt extrusion using a twin-screw extruder. The effect of PLBI content on the thermal performance, mechanical propertie,s, and ga,s permeability of the blending film,s wa,s inve,stigated. The modified atmossphere packaging (MAP),sy,stem wa,s de,signed on the ba,si,s of the ga,s permeability of material and the re,spiratory characteri,stic,s of sstrawberry. Thi,s MAP,sy,stem wa,s used for a,strawberry-pre,serving experiment. The results indicated that the blended films achieved favorable mechanical properties at a PLBI content of 15 wt%. Through adjusting the blending ratio, the CO2/O2 penetration ratio of the blending film,s wa,s reduced from 10. 57 to about 3-7. Simultaneously, the water retention capacity of the blending film,s wa,s enhanced. Thi,s make,s the blending filmss more ssuitable for air-adjusted fruit and vegetable packaging. Thi,s packaging,sy,stem can be used to extend the shelf life of strawberries up to 21 days under low-temperature storage conditions.
