Coir Fibre-Low Density Polyethylene Composite As A Packaging Material

The overall goal of current research was to produce a polymer composite consisting of coir fibre (CF) ie. coconut palm fruit fibre and low density polyethylene (LDPE) that would be suitable for food packaging application. CF and LOPE coupled with and without maleated polyethylene ( MAPE) material...
