Does Ice cream in a plastic tub have microplastics?
The short answer
Lower than most food-storage scores, for one reason: it is frozen. Cold is the strongest mitigating condition there is. What works against it is fat — ice cream is one of the fattiest things in the shop, and many polymer additives are fat-soluble.
Why Ice cream in a plastic tub scores 37
Frozen storage for the entire life of the product, which suppresses migration substantially
Very high fat content, which is the counterweight — lipophilic additives partition into fat
Paperboard tubs are polyethylene-lined, so "cardboard" packaging here is still polymer at the contact face
Scraping with a metal spoon against the tub wall is direct abrasion, repeated over the tub's life

What material touches the contents, over how much surface area, for how long. Glass and steel score near zero here; a film pressed against fatty food scores near the top.
Heat, abrasion, flexing, repeated opening, reuse beyond design life. The same bottle scores differently in a fridge and in a hot car.
What a laboratory actually counted, for this product or its category. A high number here means real particles were measured, not that the material looks suspicious.
How this specific polymer behaves — brittleness, fat solubility of its additives, thermal stability, whether it is a polymer named in existing restrictions.
What happened before you bought it. Retort sterilisation inside the pack, hot-filling, and pressurised brewing all happen at the most migration-favourable moment.
What we don't know
Frozen fatty food against polymer has barely been studied. The two drivers here point in opposite directions — cold suppresses, fat promotes — and nobody has measured which wins. That genuine uncertainty is why this is grade C and not something more confident.

Each with the finding we use it for and the limitation that finding carries — because a study quoted without its boundaries is how this subject got so noisy.
- peer-reviewed2023
Hussain 2023 (Nebraska) — Three minutes of microwaving released up to 4.22 million microplastic and 2.11 billion nanoplastic particles per square centimetre of container surface.
Limitation: Polypropylene and polyethylene containers with water and acetic acid, not real food. The headline figure is the worst case in the study, per cm², not per meal.
- report2026
Earth Action 2026 — Estimated roughly 1,000 tonnes of microplastics migrate from packaging into food and drink annually — about 130 mg per person per year — with PET bottles responsible for around a third, and found UV exposure can raise release up to 100×.
Limitation: An industry-funded modelling exercise, not a laboratory study, and not peer-reviewed. We use it for the relative ranking of formats rather than for any absolute number.
- peer-reviewed2020
Du 2020 — Take-out containers released 3–29 microplastic particles each, with polypropylene containers the most common source.
Limitation: Counts particles above the detection limit of the method used, so it says nothing about the nanoplastic fraction, which other work suggests dominates by number.
