GIST OF ARTICLE
• Utilization of oil palm empty fruit bunch (EFB) fibre waste for packaging industry (focusing on plastic film with blow film processing)
• Incorporate use of palm cooking oil (PCO) to improve processing efficiency.
JUSTIFICATION TO STUDY
• Environmental awareness
• Utilise of local natural resource
• Improve blow film process difficulties of EFB based material.
BACKGROUND
• Increasing environmental awareness to biodegradable packaging.
Biodegradable : * can be decomposed in soil * may act as fertiliser and soil conditioner. * facilitates better yield and crops
• Amount of oil palm EFB waste generated generated by palm oil industry in Malaysia ~ 8 million tons per year -> utilise natural resources
BACKGROUND
• Characteristics of good packaging films: Good oxygen barrier
Prevent microbial spoilage during extended storage
Good tensile strength
Able to maintain structural integrity
BACKGROUND
• Oil palm empty fruit bunch (OPEFB) Cellulose (majority)
Hemicellulose
Lignin
• Packaging film Combination of OPEFB + PE = semibiodegradable
Easily processed on conventional thermoplastic extrusion blow film machine.
ADVANTAGE: • Lower density • Greater deformability • Lower cost per unit volume
BACKGROUND
• Difficulties to current biopolymer processing Not easy with increasing biodegradable material
Resistance to flow is increased in the extruder.
• Solution to difficulties addition of lubricant oil (Ref : R.N. Taranathan, 2003)
Use of vegetable oil
• Plasticizer that improve film quality
• Pro-oxidant to accelerate film degradation
EXPERIMENTAL METHOD
• MATERIAL Matrix : LDPE (Titanlane) • Supplier : Titan Polyethylene (M) Bhd. • Grade : 260 for blow film process • Melt flow index (MFI=5.05g/10min) • Density : 0.8498 𝑔/𝑐𝑚3
