Abstract
The present invention is directed to degradable blends containing polylactide, a degradable impact modifier, and a degradable plasticizer for use in packaging films. The degradable impact modifier can be a degradable, non-toxic elastomer or a degradable, non-toxic, non-elastomeric polymer having a low glass transition temperature, such as polycaprolactone and poly(ethylene glycol). The degradable plasticizer can be any plasticizer having a relatively low molecular weight, a high degree of miscibility with polylactide, and non-toxicity. The film has excellent flexibility and impact strength for packaging applications.
