CONCLUSIONS
Using PPA :
*Allowing higher LLDPE ratios to be used in the LDPE/LLDPE blends
*Allowing higher outputs at equivalent die pressures
*Allowing low melt temperatures at equivalent die pressures
* Increase the physical properties of the film by increase the concentration of LLDPE in an LDPE/LLDPE resin blend to decrease resin costs
