When it comes to bottling large volumes of water or using oversized PET containers, the often-overlooked closure—the 55mm Bottle Cap—plays a pivotal role in performance, hygiene, and consumer trust. DRJ Plasttech’s water bottle cap delivers a strong value proposition for bottlers seeking reliability, safety, and operational efficiency.

Product Overview

... and trust

Why These Features Matter

1. Matching Strength & Use Case
The two weight-height options allow bottlers to choose based on specific needs. The lighter version suits single-use bottles, while the heavier version is perfect for reusable or high-pressure applications.

2. Leak Prevention & Integrity
A major concern in bulk water packaging is leakage during transport or storage. DRJ’s 55mm caps are engineered to maintain a leak-proof seal through proper liner design and accurate threading, preventing spillage and maintaining product hygiene.

3. Durability in Real Conditions
Caps face stress from temperature variations, mechanical impact, and frequent handling. Using high-quality, impact-resistant polymers ensures these caps retain shape and function even after multiple uses.

4. Compatibility & Fit
Since DRJ manufactures PET preforms, bottles, and caps in-house, every component aligns precisely. This compatibility reduces rejection rates and ensures smooth capping operations on automated filling lines.

5. Safety & Consumer Confidence
Tamper-evident designs are a crucial feature for packaged water. DRJ’s 55mm caps include break rings or tear bands, assuring customers of product authenticity and safety before first use.

6. Sustainability
By utilizing recyclable HDPE and PP materials, DRJ supports eco-friendly packaging initiatives without compromising on performance or safety.

Common Applications

Every cap undergoes rigorous quality checks for:
