“…Increasing starch content has increased water absorption. Starch‐based materials tend to absorb water, because the hydroxyl group in starch can form a hydrogen bond with water 1,37 . In other words, water absorption is related to the amount of its penetration into the blends which increased with the starch content (the lack of a smooth and uniform continuous surface causes better water penetration, which can be seen in SEM analysis by increasing the starch wt% in the blends; see Table 3).…”

In this work, low‐density polyethylene/high‐density polyethylene/thermoplastic starch (LDPE/HDPE/TS) films were prepared with different compositions to obtain environmentally friendly materials. LDPE/HDPE/TS blends, at ratios of 95:5:15, 90:10:15, 85:15:15, 85:15:20, 85:15:25, and 85:15:30, were processed into thin films by a single‐step single‐screw extrusion. Fourier transform infrared spectra and scanning electron microscopy (SEM) micrographs confirmed the immiscibility of matrices and TS in the blend. In the SEM images, relatively good surface adhesion between matrix and starch was observed due to the presence of HDPE and glycerol in blends at low TS content. Differential scanning calorimetry analysis depicted an increase in the percentage of crystallinity with increasing HDPE. Starch presence in the blend had a more pronounced effect on the crystallization of HDPE when compared to LDPE with the long chain branching. Water absorption of the samples decreased with increasing HDPE and increased with TS content. The rheological properties of LDPE/HDPE/TS blends were investigated before and after biodegradation. Results were fitted with well‐known rheological models to achieve more valuable data about the effect of the composition as well degradation condition on the blend property. By adding HDPE in the blends, rheological properties close to the neat LDPE were obtained for LDPE/HDPE/TS films in the melt state.

Starch-based films are a valuable alternative to plastic materials that are based on fossil and petrochemical raw resources. In this study, corn and potato starch films with 50% glycerol as a plasticizer were developed, and the properties of films were confirmed by mechanical properties, surface free energy, surface roughness, and, finally, color and gloss analyses. Next, the films were overprinted using ink-jet printing with quick response (QR) codes, text, and pictograms. Finally, the print quality of the obtained prints was determined by optical density, color parameters, and the visual evaluation of prints. In general, corn films exhibit lower values of mechanical parameters (tensile strength, elongation at break, and Young Modulus) and water transition rate (11.1 mg·cm−2·h−1) than potato starch film (12.2 mg·cm−2·h−1), and water solubility is 18.7 ± 1.4 and 20.3 ± 1.2% for corn and potato film, respectively. The results obtained for print quality on starch-based films were very promising. The overprinted QR codes were quickly readable by a smartphone. The sharpness and the quality of the lettering are worse on potato film. At the same time, higher optical densities were measured on potato starch films. The results of this study show the strong potential of using starch films as a modern printing substrate.
