What Are Plastic Closures?

Plastic closures, also known as plastic bottle closures or dispensing closures, are specially designed caps and lids used to seal and dispense liquid or semi-liquid products from plastic bottles. Among them, plastic closures with valve are widely adopted in modern packaging due to their superior sealing performance, controlled dispensing, and hygienic protection.

Hopewell's plastic closures with valve are manufactured from FDA and LFGB certified food-grade PP plastic combined with food-grade liquid silicone rubber (LSR). The integrated silicone sealing valve precisely regulates liquid dispensing while automatically sealing after use, effectively preventing leakage, dripping, and backflow. This design helps maintain product freshness, improves user experience, and reduces contamination risks during storage, transportation, and daily use.

Plastic bottle closures with valve are especially suitable for applications requiring clean, mess-free, and reliable dispensing solutions.

Key Features of Plastic Closures with Silicone Valve

1. Leak-Proof Performance

The silicone valve integrated inside Hopewell's plastic closures adopts a precision cross-slit structure with zero clearance design, enabling the closure to pass a 7-day, 24-hour inverted leak-proof test. This ensures outstanding sealing reliability during filling, transportation, and storage.

2. Controlled Flow Dispensing

The non-stick silicone cross-slit valve allows liquid to dispense smoothly with a simple squeeze. The plastic bottle closures with valve achieve a 100% dispensing success rate within a ±15-degree angle, delivering precise, one-time dispensing without dripping or uncontrolled spills.

3. Tamper-Evident Design

Available in common neck finishes such as 28mm and 38mm, Hopewell's plastic closures are equipped with a tamper-evident security ring, clearly indicating first opening and ensuring product safety and integrity.

4. No Product Waste

The inverted dispensing design ensures the "last drop" of product can be fully dispensed, minimizing residue and enhancing consumer satisfaction.

5. Durable Hinge & Buckle Structure

The butterfly buckle structure of the plastic closure has been rigorously tested to withstand thousands of opening and closing cycles without breakage, ensuring long-term durability.

6. Hygienic Protection

The one-way silicone flow control valve prevents external air, dust, and contaminants from entering the bottle, maintaining hygiene and extending product shelf life.
