Makrut lime essential oil (MLO) was investigated for ripening deceleration and suppression of fungal spoilage of Cavendish bananas stored at 30.0–37.6°C and 40%–60% relative humidity. The sorbitol‐plasticized composite of carboxymethyl cellulose and polyvinyl alcohol (CMC/PVA; 3:2) was used to distribute MLO droplets (0.5%–3.0%) as it exhibited the best overall tensile properties (15.36 ± 0.90 MPa, 14.9% ± 1.19, and 486.93 ± 81.67 MPa for strength, strain, and Young's modulus, respectively). After 7 days of storage of film‐wrapped Stage‐A1 bananas, growths of the molds on cutting wounds were dramatically suppressed. The 1.0% MLO/CMC/PVA film effectively controlled the spoilages of wounds and stalks. Ripening also occurred at slower pace (by about 2 days; 70.49% weight loss vs. that of the control) when Stage‐B3 bananas were encased in the 1.0% MLO plastic sleeve. However, the MLO coatings negatively affected the appearances and colors and promoted the senescence of the coated bananas at higher MLO concentrations. Compared to the CMC/PVA film, strengths and maximum strains of the 0.5% and 1.0% MLO films were significantly higher. The strength, strain, and modulus of the 1.0% MLO film were 19.50 ± 2.52 MPa, 24.75% ± 3.84, and 562.31 ± 49.71 MPa, respectively. Water vapor transmission rate of the 1.0‐MLO film was also the smallest one (2232 ± 50.91 g/m2·day).Highlights The 1.0% MLO/CMC/PVA film exhibited improved tensile properties. The water vapor transmission rate of the film was the lowest. The film effectively controlled the spoilages of wounds and stalks. Bananas encased in sleeves made from the film ripened at slower pace.

Polysaccharides-based sustainable and biodegradable packaging materials suitable for variable conditions are potential candidates for replacing petroleum-based polymers. However, the poor hydrophobicity of polysaccharide films seriously limits their practical applications. Inspired by the phase separation of pseudobilayer films through solution-method casting, a novel and facile strategy for preparing highly hydrophobic starch/gelatinbeeswax (HSGBW) film was developed using an extrusion blowing method suitable for industrial production. The increased extrusion blowing temperature enhanced the interaction between starch and gelatin (originally used to stabilize beeswax), leading to the destabilization of beeswax and its migration to the film surface, ultimately resulting in the formation of a wax-enriched hydrophobic layer. The resultant HSGBW film exhibited excellent hydrophobicity (water contact angle: ∼106°), outperforming starch-based materials reported to date as well as outstanding water resistance, UV-blocking, self-cleaning ability, moisture, oxygen, and oil barrier properties. The HSGBW film also exhibited excellent biosafety, storage stability, rapid dissolution at high temperatures (which offers convenience for packaging certain foods that expediently require high-temperature boiling), fully biodegradable performance, and easy recyclability. Owing to these multifunctional properties, the resulting film was applied in inner food packaging under different scenarios, as evidenced by the packaging of foods with high moisture content (cucumber dumpling stuffing), high fat content (highfat powdered milk), and high oil content (chili oil seasoning). From ecological and convenience viewpoints, this work demonstrated a facile strategy for manufacturing HSGBW film for packaging materials to replace petrochemical-derived plastics in many fields, especially inner food packaging, providing new opportunities for starch-based sustainable material designs.
