Description

The Aluminum Cap GPI 70/400 is a pharma-grade aluminum closure for glass and PET jars, offering a lightweight yet secure alternative to plastic lids. It follows the GPI 70-400 thread standard and fits 100ml-250ml jars, so it provides a reliable, leak-proof seal across the full range.

Material & Construction

Pharma/food-grade aluminum construction gives this cap its light weight, excellent corrosion resistance, and durability. In addition, aluminum is 100% recyclable, and manufacturers can reuse it repeatedly without any loss of physical or molecular properties. As a result, this closure remains fully sustainable, with zero environmental footprint. It also resists high temperatures, does not age over time, and is not flammable. Unlike plastic closures, aluminum keeps its shape and seal quality even after repeated opening and closing.

• Storage: Keep in a cool, dry place away from direct sunlight and humidity, in the original packaging until use.
• Capping application: Apply with standard capping machinery, using consistent torque for a secure, tamper-evident seal without over-tightening.
• Handling: Use clean, dry equipment — aluminum’s soft surface can scratch or dent if mishandled.
• Shelf life: No expiration date under proper storage; the cap is UV-stable and resistant to aging, corrosion, and high temperatures.
