Tamper-Evident PET Preforms for Jars – Secure, Reliable & Food-Grade

At Gil Pack, we specialize in tamper-evident PET preforms for food and pharma packaging where product safety is of high priority. Using a tamper-evident cap with a tear off ring, has to be matched with a tamper evident preform, that has a special ring on the neck to hold the tamper evident ring that is on the cap.

Using a tamper-evident PET preform will eliminate the need to use a liner in the cap, as the tamper-evident ring gives the proof of first opening.

Our preforms, designed for use with Tamper Evident caps, provide maximum protection, ensuring product integrity, consumer trust, and compliance with industry safety standards. These preforms are ideal for food supplements, pharmaceuticals, and other sensitive products that require secure sealing and tamper evidence.
