31.5mm Aluminium Screw Cap with Tamper-Evident Seal and Food-Grade Plastic Retractable Pourer Spout for Olive Oil

This aluminum screw cap for olive oil features an innovative, retractable plastic pouring spout, specifically designed for liquid condiments. This advanced "two-in-one" closure system combines the classic, minimalist aesthetic of a tamper-evident aluminum outer cap with an integrated, food-grade plastic pouring spout.

Upon opening, the spout automatically extends to ensure precise, drip-free pouring; when the cap is tightened, the spout fully retracts into the bottle neck, ensuring a leak-proof seal that effectively blocks air during international transport, fully protecting the product from oxidation and preserving its freshness.

• Premium Private Label Extra Virgin Olive Oil: Perfect upgrade for luxury olive oil brands looking to replace traditional standard pourers with a high-tech, functional packaging experience that justifies premium retail pricing.
• Smart Packaging for Modern Food Brands: Highly favored by organic condiment exporters whose end-consumers demand an ergonomic, mess-free, and portion-controlled pouring experience for daily salad dressing and cooking.
• Anti-Counterfeiting Commercial Bottling: Sophisticated irreversible or structural telescopic mechanism acts as an exceptional secondary barrier, preventing fraudulent refilling and protecting brand equity for commercial estates.
• High-End Gift Sets & Organic Cooperatives: Provides a distinct marketing point for corporate buyers curating artisanal gift packs, subscription boxes, or high-margin boutique wellness food product lines.

• Capping Machine Torque Calibration: For automatic capping lines, ensure that the capping head's torque is calibrated appropriately. Excessive torque can over-compress and damage the double-coated PE liner, while insufficient torque may fail to engage the liner's sealing properties against the glass rim.
• Bottle Mouth Flatness Inspection: The double-coated PE liner relies on a flat, smooth glass bottle mouth to achieve a 100% airtight seal. Ensure your glass bottles comply with standard quality tolerances (free of glass seams or chips on the rim). We highly recommend sourcing both glass bottles and caps from our factory for a guaranteed seamless fit.
• Storage Environment Guidelines: Keep bulk stock in a cool, dry warehouse below 35°C (95°F) and away from direct sunlight. High temperatures can cause plastic distortion or affect the elasticity of the PE foam liner.
• Sterilization and Washing Temperature: If the caps need to undergo sanitization before bottling, use chemical sanitizing methods or cool-water washes. Do not subject the caps to high-temperature steam autoclaving (above 65°C / 149°F), as excessive heat can deform the plastic PP shell and cause the double-coated film on the PE liner to delaminate.
