In order to obtain casein edible films with great packing performance, gelatin as the reinforcing additive with different ratios were loaded via two methods including layer‐ by‐ layer and blending. A comparative study on structure properties between double layers and blending films made from casein and gelatin was obtained by scanning electron microscopy and Fourier transform infrared spectroscopy. The difference between the films' packing characters were conducted by water vapor permeability (WVP), optical property, and mechanical properties (including tensile strength (TS) and elongation (EAB)). The results showed that the degree of films roughness increased and the structural stability decreased as the increase of gelatin additive ratio in both double layers and blending films. Thickness and WVP both displayed a trend of increasing first then decreasing at the dividing of gelatin instead of casein in 50%. Importantly, WVP values in double layers film with a largest value of 6.95 gm−1Pa−1s−1 was higher than blending films, observably (P < 0.05). Additionally, TS in blending film was increased by 23.44% than double layers film under the gelatin additive proportion of 70%, and EAB value in double layers film was larger by 207.65% than blending film under the gelatin additive proportion of 10%.

“…TA B L E 3 Thermal properties of GEFs treated by cold plasma after plasma treatment is related to the effect of bombarding high-energy plasma species such as ions, electrons, radicals, and ultraviolet radiation on the film surface (Dong et al, 2018). Plasma etching effects would also increase the surface roughness of the films.…”

“…While cold plasma was initially industrialized to raise the energy levels of polymers and increase their adhesion and printing, it has lately appeared as a powerful tool for surface sterilization of food and food packing materials (Pankaj et al., 2015). Cold plasma processing can significantly reduce WVP due to increased twisting in the diffusion path (Dong et al., 2018). Plasma gaseous reactions can inactivate microorganisms adhered to the surfaces of the polymer over a short period.…”

Common packaging systems have the ability to delay the loss or adsorption of moisture between the food and the surrounding environment, but they cannot prevent the transport of moisture, fats, and other compounds inside the food package. Edible films and coatings can solve this problem. In addition, the addition of active compounds prevent spoilage of food, maintaining its quality during transportation and storage, and after decomposition, they are degraded to water, carbon dioxide, and inorganic compound in a short time without any toxic residue and environmental problems (Sobral et al., 2001). Currently, food packaging researches have mostly focused on biodegradable edible films and using of animal and vegetable protein sources (Tharanathan, 2003). The edible films made of proteins have good mechanical properties but high moisture permeability

“…When the plasma-treated samples are exposed to ambient environment; the newly added polar functionalities on the hydrogel films post-plasma treatment are gradually lost to the atmosphere. This phenomenon is generally referred to as hydrophobic recovery or ageing [61]. Figure 6 displays the progression in water CA values of the hydrogels with an ageing up to 10 days.…”

“…6, the water CA of the plasmatreated samples showed a slight upward trend after 10 days of storage. This observation could be rationalized by considering the rearrangement of the hydrophilic polar groups incorporated onto the hydrogel surface during plasma treatment and the subsequent reorientation of a part of these hydrophilic groups towards the bulk thereby reducing the acquired hydrophilic nature of the treated surface [61]. Subsequent to 10 days of exposure to air; trivial alterations were witnessed in the water CA values of the hydrogels.…”

Smart hydrogels comprising polyvinyl alcohol and carboxymethyl cellulose have been fabricated using a green crosslinker tetraethyl orthosilicate. The hydrogels were subjected to cold atmospheric plasma-treatment using pure Ar, pure NH 3 and a mixture of the two. Enhanced surface wettability was witnessed post-plasma treatment; irrespective of the plasma gas employed. An insignificant surface ageing of the hydrogels was marked upon exposure to air for 10 days. AFM analyses revealed the surface topographical changes at the nano level while the bulk attributes remained unaffected. The hydrogels displayed smart swelling features. The release of ibuprofen from the hydrogels in simulated gastric and intestinal fluids affirmed their potential towards oral colon-targeted drug delivery. The preliminary kinetics of drug release indicated the anomalous nature of drug transport mechanism. More so, drug release from plasma-treated hydrogels were predominantly governed by diffusion process rather than polymer chain relaxational process. The hydrogels demonstrated good biodegradability and could be efficaciously utilized as potential oral drug delivery candidates.
