Re: [GreenYes] plastics recycling education
The APC or APR is supposed to be able to help you with technical questions

Have you tried calling?

The different types of resins have different viscosities.

Blow molding uses literally a process that blows air into the mold -- 
injection molding injects the melted resin into the mold.

Check with SPI.

Best of luck!
