Kuna tofauti kubwa katika mali za kimwili za plastiki za PP na PE; plastiki za PP kwa ujumla ni ngumu zaidi, wakati plastiki za PE ni laini zaidi. Tofauti hii inasababisha usambazaji usio sawa wa joto na shinikizo vinavyotokana na usindikaji, ambavyo kwa upande wake vinaathiri ubora na mali za pellets.<\/p>

Mashine za kutengeneza granules za plastiki<\/a><\/strong> kwa kawaida huhitaji kurekebishwa na kuwekwa kwa ajili ya aina tofauti za plastiki. Ikiwa PP na PE zimechanganywa kwa ajili ya pelletizing, hii inaweza kusababisha uharibifu wa mashine au uchakavu wa mapema, na kuongeza gharama za matengenezo ya vifaa.<\/p>

Ufanisi unaweza pia kuathiriwa kutokana na matatizo ya ubora na kushindwa kwa mashine za kutengeneza granuli za plastiki wakati wa mchakato wa pelletizing. Wakati na gharama zaidi zinahitajika kurekebisha au kubadilisha vifaa, jambo ambalo hupunguza ufanisi.<\/p>
