This study is based on the application of advanced technologies for the design and development of food packaging, apples in this work, in order to improve the quality of the packaging.

The results obtained show that it is possible to use advanced technologies in the early stages of product design in order to obtain competitive products adapted to new emerging needs. The effect of composition on structural, morphological characteristics and, mechanical, barrier, antimicrobial and antioxidant properties was studied. The presence of rosehip seed oil [ The presence of rosehip seed oil in chitosan films led to the formation of flexible films with improved mechanical, gas and water vapour barrier properties and antioxidant activity.

Packaging Technology - "Packaging: A Quiet Revolution"

However, the increase of the manufacture and consumption increases the probability of exposure of humans and the environment to such nanomaterials; this brings up questions about the risks of nanomaterials, since they can be toxic.

For a risk assessment, it is crucial to know whether airborne nanoparticles of graphene and carbon nanotubes can be released from nanocomposites into the environment at their end-life, or whether they remain embedded in the matrix. In this work, the release of graphene and carbon nanotubes from the poly lactic acid nanocomposite films were studied for the scenarios of: i biodegradation of the matrix polymer at the disposal of wastes; and ii combustion and fire of nanocomposite wastes.

Thermogravimetric analysis in air atmosphere, transmission electron microscopy TEM , atomic force microscopy AFM and scanning electron microscope SEM were used to verify the release of nanoparticles from nanocomposite films. The three factors model was applied for the quantitative and qualitative risk assessment of the release of graphene and carbon nanotubes from nanocomposite wastes for these scenarios.

Safety concern is discussed in respect to the existing regulations for nanowaste stream.

Risk is estimated for kg nanocomposite wastes. Abstract Thermal, structural and physico-chemical properties of different composite edible films based on alginate and pectin with the addition of citral essential oil citral EO as an agent to improve barrier properties, were investigated. The obtained films were clear and transparent, with a yellow [ Thermal, structural and physico-chemical properties of different composite edible films based on alginate and pectin with the addition of citral essential oil citral EO as an agent to improve barrier properties, were investigated.

The obtained films were clear and transparent, with a yellow hue that increased with citral EO addition. Gas transmission rate GTR strongly depended on the polymer structure, gas type and temperature, with improvement in barrier performance for composite samples. Also, citral EO did not exert any weakening action on the tensile behavior. On the contrary, an increase of the elastic modulus and of the tensile strength was observed.

Lastly, water contact angle measurements demonstrated the dependence of the film wettability on the content of citral EO. Abstract Polylactic acid PLA films were coated by coaxial electrospinning with essential and vegetable oils clove and argan oils and encapsulated into chitosan, in order to combine the biodegradability and mechanical properties of PLA substrates with the antimicrobial and antioxidant properties of the chitosan—oil [ Polylactic acid PLA films were coated by coaxial electrospinning with essential and vegetable oils clove and argan oils and encapsulated into chitosan, in order to combine the biodegradability and mechanical properties of PLA substrates with the antimicrobial and antioxidant properties of the chitosan—oil nanocoatings.

It has been established that the morphology of the electrospun nanocoatings mainly depend on the average molecular weight MW of chitosan.

Food packaging

Oil beads, encapsulated into the main chitosan nanofibers, were obtained using high-MW chitosan Chit-H. Oil encapsulated in chitosan naoparticles resulted when low-MW chitosan Chit-L was used. The coated PLA films had higher antibacterial activity when the nanocoating contained clove oil rather than when argan oil was used, for both types of chitosan.

Nanocoatings containing Chit-H had higher antibacterial activity compared with those containing Chit-L, for both types of oil tested, due to the larger surface area of the rougher nanoscaled morphology of the coating layer that contained Chit-L. The chitosan—clove oil combination had higher antioxidant activity compared to the simple chitosan nanocoating, which confirmed their synergistic activities.

The low activity of systems containing argan oil was explained by big differences between their chemical composition and viscosity. The PLA foil is placed directly onto the metallic collector.

The Science and Technology of Flexible Packaging

Abstract New multifunctional materials containing additives derived from natural resources as powdered rosemary ethanolic extract were obtained by melt mixing and processed in good conditions without degradation and loss of additives. Incorporation of powdered rosemary ethanolic extract R into poly lactic acid PLA improved elongation [ New multifunctional materials containing additives derived from natural resources as powdered rosemary ethanolic extract were obtained by melt mixing and processed in good conditions without degradation and loss of additives.

Incorporation of powdered rosemary ethanolic extract R into poly lactic acid PLA improved elongation at break, rheological properties, antibacterial and antioxidant activities, in addition to the biocompatibility.

The good accordance between results of the chemiluminescence method and radical scavenging activity determination by chemical method evidenced the increased thermoxidative stability of the PLA biocomposites with respect to neat PLA, with R acting as an antioxidant. In vitro biocompatibility based on the determination of surface properties demonstrated a good hydrophilicity, better spreading and division of fibroblasts, and increased platelet cohesion.
