      This work presents a production of nanocomposite films based on low-density polyethylene incorporated with organoclay including cloisite 15A, cloisite 20A and cloisite 30B by melt mixing method and packaging ultra-filtrated cheese in them then investigating of coliform load of cheese during 4 weeks storage in 4 ± 0.5°C, weekly. The result showed all nanocomposite films caused to reduction of bacteria load and some of them had antibacterial effect. Liner model was significant and nanocomposite film containing 3% cloisite 15A, 3% cloisite 20A and 0% cloisite 30B introduced as optimum point.

      Key Findings:

      • More mature fresh-cut zucchini has better quality under MAP conditions.
      • Passive MAP under high-permeability films improves fresh-cut zucchini quality.
      • Fresh-cut zucchini cultivars should be selected to reduce colour and firmness loss as well as preserving nutritional compounds.
    3. Active Packaging Films from Ethylene Vinyl Alcohol Copolymer and Clove Essential Oil as Shelf Life Extenders for Grass Carp Slice (pages 383–396)

      The active film obtained by adding 3% clove essential oil to EVOH copolymers could be used in the design of antioxidant active packaging for aqueous, acidic and alcoholic food products.

      A novel approach to simulate and study the short-span compression test and folding of paperboard is presented. A specific material model is used to predict the localized deformation observed from x-ray tomograph images.

      Series of shape memory polyurethane (SMPU) were synthesized and casted into films. The films with 1500 g mol−1 poly(ethylene glycol) (PEG) showed a phase transition temperature (switching temperature, Tm) between 20 and 27°C. SMPU prepared from 1500 g mol−1 PEG with 50/50 castor oil (CO)/PEG and 40/60 1,4 Butanediol (BDO)/(PEG + CO) ratios showed excellent shape memory properties. This film had higher oxygen permeability and showed up to 67% increase in Q10 value for oxygen permeability compared with low density polyethylene.
