## 1. Executive Summary & Core Engineering Scope
PCR colour and clarity limits by percentage: 30% entry, 50% credible-claim standard and the point where clear PET needs tint or frost, 100% on select formats. Natural PCR runs grey to beige, PET carries a cast; how to specify base tone, masterbatch, ΔE band, odour and specks.

The honest answer is that colour starts to move at the first percent and clarity at about half. What matters is not the threshold but how the specification is written around it, so a 50% PCR range stays consistent from lot to lot instead of drifting between beige and grey. Here is the percentage-by-percentage picture and the six spec lines that hold it together.

For most PP and HDPE formats, 30–100% PCR is achievable : 30% is the cost-effective entry , 50% the credible-claim standard and 100% possible on select bottles, jars and tubes. Colour is affected at every level because natural PCR PP and HDPE run grey to beige and shift lot to lot ; clarity in PCR PET falls as haze rises, so clear designs above about 50% are tinted, frosted or opaque . Mid and dark tones hide the base; white and pastel need a virgin-rich outer layer or a sprayed coat , plus a wider ΔE tolerance agreed under D65 before the golden sample is signed.

Post-consumer recycled resin is a blend of whatever was collected, washed and re-pelletised. Its base tone, odour and clarity vary by lot in ways virgin resin does not. Natural PCR PP and HDPE come out grey to beige; PCR PET carries a grey or yellow cast, and haze and black specks rise with the recycled share. None of this is a defect. It is the material, and the specification has to describe it rather than hope it away.

The practical consequence is that "match my existing virgin white" is not a realistic brief above about 30%, and "match it exactly" is not realistic at any percentage. The realistic brief is: design on the base the resin gives you, colour it with masterbatch dosed to a signed standard, and agree how far a lot may drift.

Two format notes. Multilayer barrier tubes for oxygen-sensitive actives keep their five-layer EVOH structure (OTR about 0.2 against 150–300 for single-layer PE) and make the recycled-content claim on the cap and carton instead. And recycled content does not change compatibility: ethanol above about 30% still rules out PET whether or not it is recycled; see the compatibility matrix .
