Jiangsu KIWL Machinery Manufacturing Group Co., Ltd is one of the most professional manufacturers and suppliers of mineral spring water 28mm aluminum cap in China. Please rest assured to wholesale high quality mineral spring water 28mm aluminum cap from our factory. Contact us for more details.
The 28mm aluminum cap for mineral water bottles offers several advantages. Its precise 28mm size ensures a secure and leak-proof seal, maintaining the freshness and quality of the water. Made from lightweight and durable aluminum, it is resistant to corrosion and tampering, enhancing product safety. The cap is easy to open yet provides a tight closure, preserving carbonation in sparkling water. Additionally, it is 100% recyclable, supporting environmental sustainability. Its compatibility with standard bottle necks makes it a versatile and cost-effective choice for beverage manufacturers.
The 28mm aluminum cap for mineral water bottles uses either **PE (Polyethylene)** or **TPE (Thermoplastic Elastomer)** liners, each suited for different applications. **PE liners** are cost-effective and ideal for sealing still mineral water, providing a reliable barrier against contamination and leakage. They are lightweight and recyclable, making them suitable for budget-friendly, short shelf-life products. In contrast, **TPE liners** offer superior elasticity and durability, making them perfect for carbonated beverages, as they maintain carbonation and provide a tight seal. TPE liners also withstand high temperatures, making them suitable for hot-fill processes and long shelf-life products. While PE is economical, TPE is preferred for premium or carbonated water applications.

PE Liners: Characteristics and Applications
1. Material Properties
Composition: PE liners are made from polyethylene, a lightweight, flexible, and cost-effective plastic.
Durability: Resistant to moisture and chemicals, making it suitable for non-reactive contents like water.
Sealing Performance: Provides a reliable seal for still mineral water but may not be ideal for carbonated beverages due to lower elasticity.
Temperature Resistance: Performs well in moderate temperatures but may deform under high heat.
2. Common Use Cases
Still Mineral Water: PE liners are widely used for sealing still water bottles because they provide an effective barrier against contamination and leakage.
Low-Cost Applications: Due to their affordability, PE liners are preferred for large-scale production of budget-friendly bottled water.
Short Shelf-Life Products: Suitable for products with shorter shelf lives, as PE may degrade over extended periods.
3. Advantages
Cost-effective and easy to manufacture.
Lightweight and recyclable.
Provides a good seal for non-carbonated beverages.
4. Limitations
Less effective for carbonated drinks due to lower elasticity.
May not withstand high-temperature sterilization processes.
TPE Liners: Characteristics and Applications
1. Material Properties
Composition: TPE liners are made from thermoplastic elastomers, which combine the properties of rubber and plastic.
Elasticity: Highly elastic, making them ideal for carbonated beverages that require a tight seal to retain carbonation.
Durability: Resistant to wear and tear, with excellent sealing performance over time.
Temperature Resistance: Can withstand higher temperatures, making them suitable for hot-fill processes and sterilization.
2. Common Use Cases
Carbonated Mineral Water: TPE liners are the preferred choice for sparkling water and other carbonated beverages due to their superior elasticity and ability to maintain carbonation.
Hot-Fill Beverages: Suitable for products that require hot-filling, such as teas or functional drinks, as TPE can withstand higher temperatures without deforming.
Long Shelf-Life Products: Ideal for products with extended shelf lives, as TPE maintains its sealing properties over time.
3. Advantages
Excellent sealing performance for both still and carbonated beverages.
Durable and resistant to high temperatures.
Maintains elasticity and sealing integrity over long periods.
4. Limitations
More expensive than PE liners.
Slightly heavier, which may increase transportation costs.
