Silicone Wine Stopper

Xiamen Ineeds Silicone Gift Co., Ltd specializes in manufacturing custom silicone wine stoppers and silicone bar accessories.

This 2-in-1 stopper combines a pourer and a seal in one piece. It is designed for dinner parties, wine tastings, outdoor picnics, and everyday kitchen use with olive oil and vinegar bottles. The stopper keeps the bottle sealed between pours, and the spout allows liquid to be poured without removing the stopper.

For brand owners and promotional buyers, customization options include laser-engraved logos on the 304 stainless steel ring, Pantone color matching for the silicone body, and custom packaging. The stopper is suitable for wine gifts, corporate merchandise, and promotional giveaways. OEM and ODM inquiries are welcome.

Product Parameters

How the 2-in-1 Design Works

Seal Function

The silicone body forms an airtight seal when inserted into the bottle opening. This helps slow oxidation after the bottle has been opened. The seal is designed to maintain consistent pressure through repeated insertion and removal.

Pour Function

The petal-shaped spout allows liquid to be poured directly through the stopper without removing it. After pouring, the spout returns to a closed position to maintain the seal. This is useful for both wine and kitchen oils.

Material Behavior

The silicone is platinum-cured, which is a curing method chosen for its low residual byproduct profile. A post-curing step further reduces volatile compounds. The material is designed for repeated use without hardening or cracking under normal conditions.

Bottle Compatibility

The stopper fits bottle openings with an inner diameter of 18 to 22 mm, which covers standard wine bottles as well as common oil and vinegar bottles. For non-standard bottle openings, a sample can be provided to confirm fit.

Custom Branding Options

This silicone wine bottle stopper can be customized through several methods:

• Laser engraving: Logo or text engraved on the 304 stainless steel ring. This produces a permanent mark that does not wear off.
• Pantone color matching: The silicone body can be formulated to match a specific brand color.
• Custom packaging: Options include bulk packing, blister cards, hang tags, or color boxes.

For promotional orders, the stopper can be individually packaged with branded materials. OEM and ODM projects are supported, and the minimum order quantity for custom colors is 500 pieces.

Material & Compliance

The silicone sealed wine stopper is made from food-grade platinum-cured silicone, which is BPA-free and phthalate-free. The metal ring is 304 stainless steel, selected for corrosion resistance and durability.

Compliance documentation covers LFGB, FDA food-contact requirements, and REACH SVHC. Test reports are available to qualified buyers upon request. For orders shipped to the European market, we recommend confirming the applicable standards for the intended use during the inquiry stage.

The production process includes vacuum vulcanization followed by a post-curing step to reduce volatile compounds. This results in a product with minimal odor out of the packaging. Quality control covers the full production chain from raw material inspection to final shipment.

Frequently Asked Questions

Q1: Is the stopper safe for food contact?

Q2: Does the seal help keep wine fresh after opening?

A: The silicone body forms an airtight seal inside the bottle opening, which helps slow the oxidation process after the bottle has been opened. The seal is designed to maintain consistent pressure through repeated use. Actual freshness depends on storage temperature and how often the bottle is opened.

A: INEEDS is a direct manufacturer. Production covers the full chain from silicone mixing and molding to assembly and packaging, all within the company's own facility.

Q6: How should the stopper be cleaned and maintained?

A: The stopper can be rinsed with warm water, boiled for sterilization, or placed in the dishwasher. The silicone material is rated for temperatures from -40°C to 230°C. The metal ring should be dried after washing to maintain its polished appearance.
