“…Pristine PBAT fibers presented a WCA of (127 ± 1) degrees indicating a hydrophobic surface. This result agreed with previous studies 13,25 . When the percent of GT was equal or over 2% the drops were spontaneously absorbed by the fibers showing a superhydrophilic behavior typical of total a wetting state.…”

“…In view of the fact that there are different types of wounds, many products have been developed to repair different skin lesions 22 . Currently, studies involving antibacterial substances in the polymer matrix of PBAT are developed using the casting method 23,24 and electrospinnig 25 but these studies do not present applications in the area of biomaterials. In this sense, we carried out a study involving an approach different from the ones found in the literature, since we used the combination of PBAT with an aminoglycoside, GT, in order to develop a biodegradable and antibacterial curative system.…”

The development of biodegradable curative systems containing antibacterial drug are fundamental for the promotion of therapeutic actions, reducing the infections caused by microorganisms and being able to substitute conventional dressings which are not biodegradable polymers in their composition. Meeting those needs, poly (butylene adipate‐co‐terephthalate) (PBAT) and PBAT/gentamicin (GT) fibers were electrospun using different concentrations of GT. The physical–chemical, morphological, thermal, antibacterial, and biological properties of the PBAT and PBAT/GT fibers were characterized. The presence of GT modified the mean diameter, roughness, and wettability of the prepared fibers. The degree of swelling was altered with the addition of GT. PBAT/GT fibers showed antibacterial activity against Escherichia coli strains reaching an inhibitory activity above 90% in the films with 2%, 5%, and 10% of GT. In addition, the fibers did not present cytotoxicity according to ISO 10993‐5 standard. The obtained results reinforce that PBAT can be used as a curative system.

“…The antimicrobial activity against Klebsiella pneumonia and S. aureus strains indicate that these nanocomposite films can be used in food industry [ 249 ]. Nisin can also be incorporated into PBAT polymeric matrix to produce an antimicrobial packaging [ 250 ], with good results against L. monocytogenes .…”

This review presents a perspective on the research trends and solutions from recent years in the domain of antimicrobial packaging materials. The antibacterial, antifungal, and antioxidant activities can be induced by the main polymer used for packaging or by addition of various components from natural agents (bacteriocins, essential oils, natural extracts, etc.) to synthetic agents, both organic and inorganic (Ag, ZnO, TiO2 nanoparticles, synthetic antibiotics etc.). The general trend for the packaging evolution is from the inert and polluting plastic waste to the antimicrobial active, biodegradable or edible, biopolymer film packaging. Like in many domains this transition is an evolution rather than a revolution, and changes are coming in small steps. Changing the public perception and industry focus on the antimicrobial packaging solutions will enhance the shelf life and provide healthier food, thus diminishing the waste of agricultural resources, but will also reduce the plastic pollution generated by humankind as most new polymers used for packaging are from renewable sources and are biodegradable. Polysaccharides (like chitosan, cellulose and derivatives, starch etc.), lipids and proteins (from vegetal or animal origin), and some other specific biopolymers (like polylactic acid or polyvinyl alcohol) have been used as single component or in blends to obtain antimicrobial packaging materials. Where the package’s antimicrobial and antioxidant activities need a larger spectrum or a boost, certain active substances are embedded, encapsulated, coated, grafted into or onto the polymeric film. This review tries to cover the latest updates on the antimicrobial packaging, edible or not, using as support traditional and new polymers, with emphasis on natural compounds.

“…Such food packaging materials showed a drastic improvement in its thermal and mechanical properties. Zehetmeyer et al (2017) reported poly(butylene adipate-co-terephthalate) (PBAT) based biodegradable and antimicrobial electrospun films (Zehetmeyer et al, 2017). The electrospun films were produced with different contents of antimicrobial peptide nisin by electrospinning.…”

Food packaging is a multidisciplinary area that encompasses food science and engineering, microbiology, as well as chemistry, and ignited tremendous interest in maintaining the freshness and quality of foods and their raw materials from oxidation and microbial spoilage. With the advances in the packaging industry, they could be engineered as easy-to-open, resealable, active, as well as intelligent with the incorporation of sensory elements while offering desired barrier properties against oxygen and water vapor. In this regard, the use of the electrospinning approach allows producing nanofibrous packaging materials with large surface-to-volume ratios and enables the higher loading of active agents into packaging materials. Electrospun packaging materials have been produced from various polymers (i.e., synthetic and natural) and their (nano)composites, and were mainly exploited for the encapsulation of active agents for their use as active food packaging materials. The electrospinning process was also used for the deposition of electrospun fibers on films to enhance their performance (e.g., as reinforcement material, or to enhance barrier properties). They could be even engineered to provide nutraceuticals to food, or antioxidant, antimicrobial or antifungal protection to the packaged food. In this article, first, introductory descriptions of food packaging, barrier properties, and electrospinning are given. Afterward, active and intelligent food packaging materials are briefly discussed, and the use of electrospinning for the fabrication of active food packaging materials is elaborated. Particular interest has been given to the polymer-type used in the production of electrospun fibers and active properties of the resultant packaging materials (e.g., antioxidant, antibacterial, antifungal). Finally, this review paper concludes with a summary and future outlook towards the development of electrospun food packaging materials.
