Sustainability in Packaging - Using Wood Flour and Biopolymers to Reduce the Content of Fossil-Based Polymers in Packaging Applications(PPT)

摘要

'Green' filler potential ; Conversion by injection molding hot runner possible ; Increase in tensile stiffness from 58% up to 105% ; Increase in flex stiffness from 54% up to 77% ; No significant effect on impact properties ; Drop in elongation - loss of toughness > PP ; Drop in elongation - loss of toughness > at 15% woocl/PLA ; No significant effect of wood on PLA brittleness ;Melting enthalpy decreases with increasing wood loading ; Difficult thermoforming ; Use of additive to improve processibility of PLA > Biomax~R ; Use of compatibilizers for improved mixing (maleated olefins) ; Use of coupling agents for improved stress transfer between wood and polymer matrix.
