PET shines at ProFood Tech
from Packaging World
Historically it’s been challenging to use a lugged metal closure on a hot-filled PET container because, unlike glass, whose durable neck finish readily accepts such closures, a PET neck finish is subject to deformation when it’s exposed to the high temperature inherent in hot filling. But recent developments have overcome these challenges, and sure enough the Francesco Rinaldi container in the middle has a metal lugged closure. The key advantage to such a closure is that when it is removed by the consumer, the “pop” sound of vacuum release is part of the experience.
