A series of study was conducted to explore a practical methodology for fabricating films providing suitable properties required for a particular application as fresh produce packaging. Targeted properties include high oxygen transmission rate (OTR) of greater than 10,000 cc!m2.day, optimum mechanical integrity, clarity (low haze of < 10%) and low film to film adhesion (no film blocking). Focus was on examining the advantages of co-extrusion process in designing multilayer film structure to achieve the best possible characteristics. Mettalocene PE(mPE)was selected as a base material for all films tested. low modulus of mPE films was effectively improved through an incorporation of 10wt% of HOPE,both for monolayer blended films and co-extruded three layer films containing blended HDPE/mPElayer at either core layer or inner layer. In addition to modulus, other mechanical properties as well as OTR, haze and film blocking were investigated as a function of layer arrangement, mixing method of HDPE/mPEblends and different melt flow HOPE resins. While monolayer blended HDPE/mPEfilms possessed enhanced mechanical properties over those of mPE, these films were hazy. Interestingly low haze of <10%was obtainable when the blended HOPI/mPE was designed as the core layer for co-extruded three layer films. However,these co-extruded films with mPE/(HDPEblended mPE)/mPE configuration exhibited undesirable fim blocking, as generally encountered in mPE blown film production. Thus, attempts were made to determine a practical approach in optimizing all required performance. Findings along with discussion and hypotheses were included in this paper
