The food and drug administration fda has stated that ethylene vinyl acetate is safe when used in food production packaging or transportation and it s not an especially dangerous material.
Ethylene vinyl alcohol evoh is a formal copolymer of ethylene and vinyl alcohol because the latter monomer mainly exists as its tautomer acetaldehyde the copolymer is prepared by polymerization of ethylene and vinyl acetate to give the ethylene vinyl acetate eva copolymer followed by hydrolysis.
Polypropylene pp also known as polypropene is a thermoplastic polymer used in a wide variety of applications.
It is produced via chain growth polymerization from the monomer propylene.
