Durability is engineered into every gram of our PET preforms.
Finite-element analysis (FEA) optimises wall thickness distribution, delivering bottles that survive 25 kg top-load and 1.5 m drop tests-benchmarks that exceed ISTA 6-Amazon.com requirements.
For carbonated beverages, a proprietary 30 mm neck with 2.4 mm root radius resists stress-cracking under 6 bar pressure, eliminating dome fractures during tropical transit.
In the personal-care aisle, impact-modified PET grades withstand repeated pump-actuation cycles without crazing, reducing leakage complaints by 35 %. Even after 30 wash cycles in returnable systems, our crystallised-base preforms maintain tensile strength above 45 MPa, proving that PET can outlast glass in closed-loop logistics.
All data are validated through third-party drop-tower and vibration tests, giving exporters the documentation needed for insurance claims and brand warranties.
