“…The glycerol effect on bionanocomposite film can also be indicated by a hydrogen bond competition among polymers and polymer-plasticizers when plasticizers are incorporated into the polymer matrix [22]. Similar results can be observed in other PVA film studies incorporating plasticizers such as sorbitol, propylene glycol, and polyethylene glycol [25][26][27]. Therefore, it can be assumed that PVA-based films will show a more dense and rigid form with increasing levels of CNC and less glycerol incorporation.…”

The current research is intended to optimize the formulation of bionanocomposite films produced from polyvinyl alcohol by adding glycerol (4–8%) and cellulose nanocrystals extracted from pineapple crown leaf (3–7%). The interaction between the bionanocomposite films characteristic, such as thickness, tensile strength, and elongation are determined using a response surface methodology with a central composite design. To show the practical relevance of the prediction model, the optimized bionanocomposite film composition required additional validation. Adding glycerol at 4% and cellulose nanocrystal at 3.52% was determined to be the film’s optimum parameters. Improved mechanical properties with a low thickness value and high elongation were found in the enhanced film formulation. The findings showed that an optimized bionanocomposite film formulation based on polyvinyl alcohol with glycerol and cellulose nanocrystals from pineapple crown leaves provided good model validation and could be utilized optimally in the food packaging application.

“…This study showed that the addition of high glycerol and NCC decreased the thickness, tensile strength, and elongation of the biocomposite film. Aprilia et al also reported that the irregular structure of the reinforcing material reduced composite strength because of the bonds’ inability to support the stress transfer of the polymer matrix [ 51 ]. The weakness in the interfacial areas would decrease the effect of stress transfer from the polymer matrix to the filler component, lowering the strength of the films [ 39 ].…”

This study employed response surface methodology to optimize the preparation of biocomposites based on whey protein isolate, glycerol, and nanocrystalline cellulose from pineapple crown leaf. The effects of different concentrations of nanocrystalline cellulose as a filler and glycerol as a plasticizer on the thickness, the tensile strength, and the elongation at break on the resulting biocomposite films were investigated. The central composite design was used to determine the optimum preparation conditions for biocomposite films with optimum properties. The regression of a second-order polynomial model resulted in an optimum composition consisting of 4% glycerol and 3.5% nanocrystalline cellulose concentrations, which showed a desirability of 92.7%. The prediction of the regression model was validated by characterizing the biocomposite film prepared based on the optimum composition, at which the thickness, tensile strength, and elongation at break of the biocomposite film were 0.13 mm, 7.16 MPa, and 39.10%, respectively. This optimum composition can be obtained in range concentrations of glycerol (4–8%) and nanocrystalline cellulose (3–7%). Scanning electron microscope images showed that nanocrystalline cellulose dispersed well in the pure whey protein isolate, and the films had a relatively smooth surface. In comparison, a rough and uneven surface results in more porous biocomposite films. Fourier transform infrared spectroscopy revealed that nanocrystalline cellulose and glycerol showed good compatibility with WPI film by forming hydrogen bonds. The addition of nanocrystalline cellulose as a filler also decreased the transparency, solubility, and water vapor permeability and increased the crystallinity index of the resulting biocomposite film.

Silica derived from variety of sources and its functionalized form has been studied as an antiblock additive in polypropylene (PP). Commonly inorganic antiblock additives are added to PP films to reduce the blocking and facilitate separation of polymeric films. However, such types of additives can cause a reduction of clarity in transparent films. In the present work, comparative analysis of silica obtained from various sources specifically from rice husk ash and its further functionalization/modifications using n-octyltriethoxysilane has been performed. Since silica synthesized via rice husk ash was obtained from waste (rice husk ash), this further solves the problem of ash disposal. The functionalized silica has been characterized using Fourier transform infrared (FTIR) spectroscopy, and thermogravimetric analysis (TGA). The morphological analysis and particle shape and size has been characterized by scanning electron microscopy (SEM). The melt flow index (MFI), yellowness index and other mechanical characterizations including tensile and impact strength was performed for 30–40 µm thick tubular quenched polypropylene (TQPP) films. These films were evaluated to have high transmittance (above 93%), high clarity (above 98%) and very low haze (less than 2%) indicating the high transparency and improved optical properties. The blocking force and optical properties are quite similar for TQPP film containing silica synthesized from rice husk ash and commercial grade silica and hence, proving silica synthesized from rice husk ash to be an effective substitute for commercial silica in TQPP films.
