Juice Bottles: Clear PET, Cold Fill, and the Hot Fill Trap
By Joe Joo · 8PCK · Shantou · Updated 26 October 2026
Juice is sold on colour and clarity, which means PET. It is also the category where hot fill quietly deforms standard bottles.
Juice bottles are clear PET with a wide neck for filling speed. The specification question is not the bottle, it is the fill temperature.
The free Bottle Spec Checker tests whether your neck fits the closure and whether the wall survives a pump stroke.

Cold Fill Versus Hot Fill
Most juice in PET is cold-filled and preserved by pH, preservative or chill chain. Above about 60 °C standard PET deforms — heat-set PET or PP/HDPE is the alternative.
Cold Fill
Standard PET; the default.
Hot Fill
Heat-set PET or PP; different mould and price.
Necks and Closures
28/410 for 250–500 ml with a tamper-evident cap; 38 mm where filling speed matters. The orifice is none for juice — it is poured, not dosed.
Where It Fails
Thin walls buckle on a fast filling line, and a bottle that looks fine empty can deform when filled cold at high speed.
