    PET

PREFERRED

PET and PET co-polymer resins which have a crystalline melting point between 225 and 255C

Materials of a lower melt point or non-crystalline materials become sticky in the reclaimers’ pre-extrusion dryer and prevent the material from flowing through the process. Materials of a higher melt point remain solid in the reclaimers’ extruder and cause blockages in melt screens. Both conditions greatly hinder the ability of the reclaimer to operate.

Bio-Based PET Resins

Bio-based PET resin, in which the MEG or PTA components are sourced from biological materials such as sugar cane residue, is fully compatible with petroleum-based PET in the recycling process. Bio-based PET should not be confused with PET containing bio- or oxo-degradable additives.

Recycled PET (rPET) Content

The use of postconsumer PET in all packages is encouraged to the maximum amount technically and economically feasible.

DETRIMENTAL

None listed.

RENDERS NON-RECYCLABLE

Look-alike packaging made of other, non-compatible resins in the PET supply stream. Non-crystalline PET structures with melting points outside the Preferred range.

REQUIRES TEST RESULTS

Blends of PET and other resins designed to enhance properties in the intended first use with unknown residual effects in future uses of the recovered resin.
