“…Incorporating nanoparticles could enhance the barrier properties of packaging films; however, this also affects the mechanical properties of films [16]. Lowering both OTR and WVTR to the minimum can significantly affect food quality [17].…”

In this research, ethyl cellulose films were prepared by a simple, easy, controlled one-pot method using either ethanol or ethyl lactate as solvents, the films being formed at 6 °C. Titanium dioxide nanoparticles were incorporated to improve the oxygen transmission and water vapour transmission rates of the obtained films. This method used no plasticizers, and flexible materials with good mechanical properties were obtained. The resulting solvent-free and transparent ethyl cellulose films exhibited good mechanical properties and unique free-shapable properties. The obtained materials had similar properties to those reported in the literature, where plasticizers were incorporated into ethyl cellulose films with an elastic modulus of 528 MPa. Contact angles showed the hydrophobic nature of all the prepared materials, with contact angles between 80 and 108°. Micrographs showed the smooth surfaces of the prepared samples and porous intersections with honeycomb-like structures. The oxygen and water vapor transmission rates were the lowest for the ethyl cellulose films prepared in ethyl lactate, these being 615 cm3·m−2·day−1 and 7.8 gm−2·day−1, respectively, showing that the films have promise for food packaging applications.

“…It can be noted that tested materials O 2 permeability is far below 19.7 cm 3 mm/m 2 24h. Values can be compared to synthetic films like poly (ethylene‐terephtalate), poly (vinil‐chloride), oriented polyamide/polypropylene, as well as biopolymer films derived from pectin, some of the composites pectin/alginate/whey protein concentrate or PuOC composite without PE layer 18,31,46–48 . Permeability and transmission rates for tested films are below values reported for chitosan, chitosan‐gelatin and chitosan‐gelatine‐starch films and far below values reported for commercially available bio‐based polymer materials Mater‐Bi P25 (based on aromatic/aliphatic biodegradable polyesters), PLA Nativia P30 (polylactic acid), Ecovio P50, Ecovio P30 (copolyesters of “ecoflex” and polylactic acid) 3,13 …”

Pumpkin seed oil cake/polyethylene film as new food packaging material, with perspective for packing under modified atmosphere

et al. 2020

Biopolymer packaging materials show increasing perspective in food packaging. Main limitation remains their high water sensitivity and poor water vapour barrier properties, compared to non polar materials of synthetic origin like polyethylene. In this paper, biopolymer layer obtained from by-product of oil industry (pumpkin seed oil cake) was laminated on polyethylene in order to obtain new packaging material that would preferably combine water barrier properties of polyethylene and oxygen barrier properties of biopolymer composite material and perform satisfactory mechanical properties. Obtained two-layer material showed good barrier properties for water vapour (7-8 g/m 2 24h), as well as oxygen (12-45 cm 3 /m 2 24h) and light. In addition, mechanical and water sensitivity tests were performed and results showed that new material inherited biopolymer film water sensitivity and mechanical properties with slight improvement. Measured tensile strength and elongation at break was 2-4 MPa and 150-250% in transversal direction and 6-8 MPa and 100-150% in longitudinal direction. Packing in modified atmosphere assay showed that new material can be used for this purpose with good control of oxygen concentration, while packing under increased concentration of CO 2 could be performed for shorter storage period. New two layer material shows promising properties for sensitive food packing under modified atmosphere conditions with reduced use of synthetic, oil-based materials.

Food packaging plays a crucial role in product storage, transportation and distribution. This study is dedicated to the development of high barrier blends for food packaging through the melt blending of polyethylene terephthalate (PET) and polyethylene 2,6‐naphthalate (PEN). The blends underwent comprehensive characterization involving chromaticity analysis, DSC, FTIR and XRD. Results indicated that the blend comprising 30 wt% PEN and 70 wt% PET exhibited superior structural properties, making it suitable for the production of beverage packing bottles. To evaluate the bottle properties, SEM, AFM, TG analysis and permeability testing were conducted. Comparatively, the barriers to O2, CO2, and water vapour of PEN/PET bottles were 3.52‐fold, 7.36‐fold and 2.25‐fold higher than PET bottles, and the mechanical properties and UV blocking properties have also improved. The PEN/PET bottles exhibited good thermal stability, with thermal shrinkage temperature and initial decomposition temperature at 87.5°C and 254°C, significantly higher than PET bottles (p < 0.05). Interestingly, the thermal shrinkage rate of PEN/PET bottles was measured at 87.5%, notably lower than that of PET bottles at 90.9%, indicating that PEN/PET bottles had good thermal stability. Additionally, beverage stored in PEN/PET bottles demonstrated lower dissolved oxygen content, suggesting promising applications for PEN/PET bottles in beverage packaging.
