From sample trials to final delivery
Vacuum Bag Film: PA Co-extruded Film
Coomax Packaging’s vacuum bag film is a high-performance PA (Polyamide) coextruded film engineered for demanding protective packaging applications. Utilizing advanced 9-layer coextrusion technology, we produce films with exceptional barrier properties, puncture resistance, and durability. This multi-layer process allows for precise control over the film’s structure, enabling optimal performance for a wide range of products.
We offer two primary structural configurations to meet specific client needs:
- Symmetrical Structure (PE/PA/PE): This balanced construction provides excellent mechanical strength and consistent barrier performance from both sides. It is ideally suited for products requiring robust, all-around protection and superior puncture resistance, such as industrial parts, sharp-edged components, and heavy-duty frozen goods.
- Asymmetrical Structure (PA/PE): This design features the high-barrier PA layer on one exterior side and the strong sealing PE layer on the other. It is optimized for applications where maximum barrier protection against oxygen and aroma is critical on one surface, while a reliable, strong seal is paramount on the opposite side. This structure is commonly selected for sensitive food products, medical supplies, and specialty chemicals.
Both structures are designed to meet the essential requirements of vacuum skin packaging and other modified atmosphere packaging (MAP) applications, ensuring extended shelf life and superior product presentation.
Our Manufacturing and Operational Excellence
As a dedicated manufacturer, Coomax Packaging’s strength lies in our integrated production capabilities and stringent management systems.
- Advanced Coextrusion Lines: Our facility operates state-of-the-art 9-layer coextrusion lines. This allows us to engineer films with tailored layer compositions, ensuring precise functionality for barrier, strength, and sealing.
- In-House Production Control: We manage the entire production process internally, from raw material selection and compounding to extrusion and finishing. This vertical integration guarantees consistent quality, supply chain reliability, and the flexibility to accommodate custom formulations.
- Comprehensive Quality Management: Our quality assurance protocol is embedded at every stage. We conduct rigorous testing for key parameters including tensile strength, oxygen transmission rate (OTR), seal integrity, and puncture resistance to ensure every batch meets specified performance standards.
- Technical Expertise & Development: Our engineering team possesses deep expertise in polymer science and film structure design. We collaborate closely with clients to develop solutions for specific challenges, whether related to barrier needs, mechanical properties, or processing compatibility on their packaging lines.
- Scalable and Reliable Output: Our modern manufacturing setup and efficient operational management enable us to deliver both large-volume orders and specialized custom runs with the same commitment to precision and on-time delivery.
