Customized Waterproof Food Grade Colored Silicone Sealing Plug

Welcome to our product page! Our Customized Waterproof Food Grade Colored Silicone Sealing Plug is engineered to deliver reliable sealing performance, food-safe security, and personalized aesthetics, tailored to meet the diverse needs of global clients in food & beverage, home appliance, laboratory, and industrial fields. With strict quality control and flexible customization options, we bring you a sealing solution that combines functionality, safety, and visual appeal.

Product Overview

Crafted from high-quality food-grade silicone rubber, our sealing plug is designed to provide airtight, waterproof, and leak-proof protection for various containers and equipment. Unlike ordinary sealing products, it features FDA, LFGB, and ROHS certifications, ensuring no harmful chemicals leach into food, beverages, or sensitive materials—making it safe for direct contact with edible products and medical supplies. The colorful design adds a touch of personalization, while the customizable size, shape, and hardness make it adaptable to any sealing scenario, from household storage to industrial production.

Core Features

Food Grade Safety: Made of 100% food-grade silicone. Complies with FDA, LFGB, ISO, and ROHS standards, suitable for food & beverage storage, kitchen appliances, and medical containers. It will not affect the flavor or quality of the contents, making it a trusted choice for food-related applications.
Superior Waterproof & Airtight Sealing: Adopts a precision-molded structure with excellent elasticity, ensuring a tight fit for various bottle necks, holes, and container openings. Effectively prevents water, moisture, dust, and contaminants from entering, while also retaining the freshness of food and the integrity of sensitive materials. Ideal for both indoor and outdoor applications that require moisture protection.

Precision-molded silicone sealing plug structure

Customizable Design: Fully customizable to your specifications—size (0.3mm to 700mm diameter), shape (cylindrical, tapered, conical, or custom), color (Pantone color matching, including transparent, red, blue, yellow, green, etc.), and hardness (30-90 Shore A). We also support logo engraving, embossing, or debossing for brand customization, helping you stand out in the market.
Durable & Versatile: Resistant to extreme temperatures (-40℃ to 200℃), UV rays, and common chemicals, ensuring long-term use without deformation, cracking, or aging. Easy to clean, reusable, and suitable for a wide range of scenarios: food storage bottles, wine bottles, laboratory glassware, perfume bottles, electronic equipment, automotive components, and industrial machinery sealing.
Easy to Use: Lightweight and flexible, the plug can be easily inserted and removed without damaging the container or equipment. Its smooth surface ensures no scratches, and it is easy to clean with water or mild detergent, maintaining hygiene standards for repeated use.
