“…Therefore, the presence of epoxidized palm oil (EPO) are believed to improve interfacial adhesion and brittleness of PLA/DSF bicomposites. The improvement of tensile strength of PLA biocomposite were also reported by Ali et al [6], Anuar et al [16] and Chieng et al [17]. This is because the intermolecular forces are reduced and polymer chain interaction increased with the addition of EPO which are enhance flexibility and extensibility.…”

The exploration of new biocomposites that are environmental friendly is gain attention due to depletion of petroleum resources and increasing global environmental concern. Therefore, the investigation of environmental friendly and sustainable materials requires to substitute the synthetic based materials. This project is conducted to investigate the effect of supercritical carbon dioxide on tensile properties of PLA/DSF biocomposite films. The PLA/DSF biocomposites are produced via solvent casting method. Then, the samples are treated under supercritical carbon dioxide (SCCO2) at 40 o C and at 200 bar pressure. From tensile properties, it was found that the tensile strength and modulus for untreated and treated PLA/DSF biocomposite are higher compared to net PLA which are 24.9 MPa and 23.5 MPa. Thus, the addition of durian skin fiber improved the mechanical strength PLA polymer. But, the presence of foams and pore in treated PLA/DSF biocomposites decreased its tensile properties by 1.4 MPa less compared to untreated samples as confirmed by morphological observations under scanning electron microscope.

“…Brittleness also affect the processability which can be modified with plasticizer. Plasticizer like epoxidized palm oil (EPO) was reported able to enhance the flexibility of polymer chain [6,7]. Natural-based plasticizer are more preferred which are categorized as non-tocixity and low migration rates [8].…”

“…EPO acts as a plasticizer to improve the flexibility of PLA biocomposites. Therefore, the porosity of the treated sample increased its degradation rate [10,23]. The weight loss experienced by the untreated PLA-DSF-EPO-CEO biocomposite after 80 days was 85.18% ( Fig.…”

“…This attempt could help in reducing the environmental pollution by decreasing the number of organic wastes. Besides, the processability of films can be increased with plasticizers that contribute to decreasing the glass transition temperature (Tg) and enhance the polymer chain flexibility [10]. This plasticizer also might overcome specimen's brittleness created by high intermolecular forces.…”

Biopolymer products that is biodegradable presently attracting an attention from researchers and industry. The biodegradable packaging based on polylactic acid (PLA), durian skin fibre (DSF), epoxidized palm oil (EPO) and incorporated with cinnamon essential oil (CEO) as antimicrobial agent have been developed and showed to be a promising field of research. This paper reported the effects of supercritical carbon dioxide on the degradation and antimicrobial properties of PLA biocomposite films produced via solvent casting. The biocomposites underwent supercritical carbon dioxide (SCCO2) treatment at two different conditions under 40 °C temperature and at 100 bar and 200 bar pressure. Water absorption test showed that the untreated PLA biocomposite absorbed most water as compared to treated PLA biocomposite with SCCO2 at 5.1%. This is due to the hydrophilic nature of the fibre that absorbed water molecules. Soil burial test showed that the treated PLA biocomposite possessed the highest value of weight losses after 80 days with 97.8%. Biocomposite with the presence of CEO demonstrated antimicrobial activity against both gram-positive and gram-negative bacteria. This showed that SCCO2 significantly improved the properties of PLA biocomposite films. The supercritical fluid treatment of PLA biocomposite could be an alternative for active packaging industries to ensure that the packaging product meets the requirement by consumers as well as being an eco-friendly product. ABSTRAK: Produk biopolimer yang biodegradasi pada masa ini menarik perhatian dari penyelidik dan industri. Pembungkusan biodegradasi berasaskan polilaktik asid (PLA), serat kulit durian (DSF), minyak kelapa sawit terepoksi (EPO) dan ditambah dengan minyak pati kayu manis (CEO) sebagai agen antimikrobial telah dibangunkan dan menjadi bidang penyelidikan. Artikel ini melaporkan kesan karbon dioksida superkritikal terhadap sifat-sifat degradasi dan antimikrobik dari filem biokomposit PLA yang dihasilkan melalui pemutus pelarut. Biokomposit telah menjalani rawatan superkritikal karbon dioksida (SCCO2) pada dua keadaan yang berbeza di bawah suhu 40 °C pada 100 bar dan 200 tekanan bar. Ujian penyerapan air menunjukkan bahawa biocomposite PLA yang tidak dirawat menyerap kebanyakan air berbanding komposisi lain dengan 5.1%. Ini disebabkan sifat hidrofilik serat yang menyerap molekul air. Ujian penanaman dalam tanah menunjukkan bahawa biocomposite PLA yang dirawat mempunyai nilai kehilangan berat tertinggi setelah 80 hari dengan 97.8%. Biokomposit dengan kehadiran CEO menunjukkan aktiviti antimikrobial terhadap bakteria gram-positif dan gram-negatif. Ini menunjukkan bahawa SCCO2 meningkatkan sifat-sifat filem biocomposite PLA. Rawatan cecair superkritikal PLA biocomposite boleh menjadi alternatif bagi industri pembungkusan untuk memastikan produk pembungkusan memenuhi keperluan pengguna serta menjadi produk mesra alam.

“…Plasticizer from natural resources such as rubber seed oil, olive oil, corn oil, soybean oil, palm oil and neem oil are widely used due to their lower toxicity, low cost, renewable resources, biodegradability, good lubricity and lower volatility [6]. Ali et al [7], Chieng et al [8] and Al-Mulla et al [9] studied the effect of epoxidized palm oil (EPO) incorporated into PLA on mechanical properties. They found that the flexibility was increased about 16% and elongation at break of PLA also was improved from 60 to 100% when 5 wt.% of EPO was added.…”

Packaging is an essential component in food industries. Packaging protects food from spoilage between processing and usage by the consumer. In this study, biocomposites of poly(lactic acid) (PLA) reinforced with durian skin fibre (DSF) were prepared by extrusion and compression moulding. Epoxidized palm oil (EPO) was added into PLA/DSF biocomposite as a plasticizer. The results showed that the thermal stability of PLA/DSF biocomposite with EPO has not much difference compared to without EPO. The degradation time of PLA/DSF biocomposite also faster after it was disposed to the landfill as it took around 65 days to degrade. Fourier transform infrared (FTIR) confirmed the stability of EPO where the oxirane group of EPO existed in the PLA/DSF biocomposite. Therefore, PLA/DSF biocomposite with addition of EPO can be effectively used for food packaging application.
