Fully Automatic 5L High Barrier Fluorinated Bottle Co-Extrusion Blow Molding Machine

Meeting the growing demand for superior quality and safety in packaging for food, pharmaceuticals, cosmetics, and chemical products, traditional single-layer plastic packaging can no longer meet high-end requirements. To address this challenge, Tongfa has launched its advanced high-barrier multi-layer plastic bottle blow molding production line. At the heart of this line is the industry-leading COEX blow molding machine (co-extrusion blow molding machine), which integrates the entire process from raw materials to finished products. Offering a complete turnkey project solution—including customized fill-line capability—it marks a new era of intelligent and customized packaging production.

The COEX blow molding machine employs precision multi-layer co-extrusion technology. In a single machine, it can simultaneously process three to six layers (depending on configuration) of different materials (such as PE, PP, PET, EVOH, PA, etc.).

• Exceptional Barrier Properties:Effectively blocks oxygen, water vapor, UV light, and more, significantly extending the shelf life of contents and preserving their flavor and quality.
• Material Optimization:The inner layer can use food-grade safe materials, the middle layer incorporates high-barrier materials, while the outer layer can utilize high-strength or printable materials, optimizing cost without compromising performance.
• Robust Structure:The multi-layer construction provides bottles with higher impact strength and pressure resistance, ensuring safer transportation.

We provide far more than just a machine—we deliver a complete production solution: a turnkey project. This means we offer end-to-end responsibility, from project assessment and plant layout to equipment supply (including the COEX blow molding machine, raw material handling systems, molds, online inspection systems, etc.), installation, commissioning, personnel training, and final mass production.

• Worry-Free Convenience:Customers avoid the hassle of coordinating multiple suppliers; we provide seamless start-to-finish service, ensuring efficient and smooth project implementation.
• Highly Integrated System:The entire line works in harmony, optimizing the production process and maximizing efficiency and stability.
• Production-Ready Assurance:We guarantee that the production line is delivered ready for stable operation, meeting all predetermined technical indicators and product quality requirements.
