Crystal clarity and design freedom make PET preforms the go-to for premium cosmetics.
A 24 mm, 11 g preform blown to a 200 ml oval bottle achieves haze < 0.5 % and gloss > 90 GU - rivalling flint glass - while surviving 1.2 m drop tests critical for e-commerce channels.
UV-block masterbatch at 330 nm protects retinol or vitamin C serums from photodegradation, extending shelf life 40 %.
Matte varnish, soft-touch lacquer or metallisation are applied post-blow, allowing MOQs as low as 10 k units for indie brands. 100 % rPET grades now reach colour L* > 90, giving prestige labels a fully recyclable story without sacrificing premium shelf appeal.
