Our Manufacturing Facilities
Each factory focuses on a specific packaging material, ensuring professional production, stable capacity and consistent quality.
Glass Bottle & Jar Manufacturing Facility
Our glass packaging manufacturing facility specializes in the production of food and beverage glass bottles and jars. The factory is equipped with advanced glass forming lines and operates under strict process control to ensure structural strength, dimensional consistency and stable quality.
A key focus of our glass manufacturing is enhanced impact resistance. Through optimized glass formulation, controlled wall thickness and precise molding processes, our bottles and jars offer improved resistance to breakage during filling, transportation and handling.
The facility supports a wide range of standard glass bottles and jars, as well as customized designs including bottle shape, capacity, color and surface decoration.
Key Capabilities & Features
Food-grade glass bottles and jars
Enhanced durability and impact resistance
Consistent wall thickness and accuracy
Custom shapes, colors and decoration
Stable capacity for export markets
Plastic Packaging & PET Preform Facility
Our plastic packaging facility focuses on PET preforms, plastic bottles and plastic caps for food and beverage applications. The factory uses food-grade PET materials and standardized production processes to ensure safety, consistency and high production efficiency.
PET preforms produced by this facility are designed for compatibility with standard blow molding equipment, allowing customers to achieve stable bottle forming and efficient large-scale production. By shipping preforms instead of finished bottles, customers can significantly reduce transportation and warehousing costs.
The facility also supports customization in neck finish, weight, color and final bottle shape, making it suitable for both market testing and long-term production projects.
Key Capabilities & Features
Food-grade PET preforms and bottles
High compatibility with blow molding lines
Flexible size, weight and color options
Cost-efficient logistics advantages
Support for recycled PET (rPET)
Metal & Aluminum Can Manufacturing Facility
Our metal packaging facility specializes in aluminum cans and metal packaging components for beverage and food applications. Aluminum cans produced at this facility are lightweight, durable and designed to support high-speed filling and sealing operations.
Sustainability is a core advantage of aluminum packaging. Aluminum cans offer high recycling rates and can be recycled infinitely in a closed-loop system. This makes them an ideal packaging solution for brands seeking to reduce environmental impact while maintaining product protection.
The facility applies strict quality controls and coating standards to ensure product safety, including interior lining systems that prevent direct contact between beverages and aluminum.
Key Capabilities & Features
Aluminum cans for beer and RTD beverages
Lightweight, durable and transport-efficient
High recyclability and sustainability
Interior lining for food safety
Consistent quality for export markets
By operating three specialized manufacturing facilities within one group, we are able to coordinate production, control quality and optimize delivery across glass, plastic and metal packaging formats. This integrated structure allows us to support customers with multi-material packaging needs while maintaining consistency and reliability.
The Hong Kong–based sales and export company works closely with each facility to ensure clear communication, accurate project coordination and efficient execution from production to global delivery.
