Product Description
Aluminium Screw Cap 31.5mm with PE Pourer Insert for Olive Oil Bottle
Product Overview

High-performance aluminium screw caps integrated with a two-part PE pourer insert, engineered specifically for high-volume olive oil and liquid condiment bottling.

The outer shell features premium, rust-resistant aluminium that provides a classic, upscale appearance and reliable continuous thread sealing. Inside, the food-grade PE insert is meticulously split: one part seats firmly into the glass bottle neck to serve as a precise, non-drip pourer, while the upper section remains nested inside the cap to guarantee an airtight, leak-proof primary seal before opening.

Handling & Safety Precautions
  • Torque & Height: Calibrate capping pressure and torque precisely. Over-tightening cracks the PE pourer; under-tightening causes spinning or leaks.
  • Bottle Tolerance: PE inserts rely on interference fit with the glass neck. Ensure bottles meet CETIE or standard internal tolerances. Use our matching bottles or send dimensions for validation.
  • Temperature Limit: PE pourers are rated for room-temperature and cold fills only. Avoid hot filling above 65°C (149°F) to prevent softening and seal failure.
  • Storage & Handling: Aluminium shells dent easily. Stack within height limits; store in dry, cool, humidity-free conditions away from corrosive vapors to protect printing and seal elasticity.
