Bag blowing machine price

The price is primarily driven by the screw diameter (e.g., 45mm to 65mm) and the effective film width. High-end machines utilize bimetallic screws and barrels for wear resistance, which extends service life. Additionally, the inclusion of an automatic tension control system and high-speed rotary die heads will increase the initial cost but significantly improve film thickness uniformity and production efficiency.

Buyers must decide between monolayer (single layer) and multi-layer (ABA or ABC) co-extrusion machines. Multi-layer machines allow for the use of recycled materials in the middle layer to reduce costs while maintaining a high-quality surface finish. Ensure the machine is compatible with specific resins such as LDPE, HDPE, or LLDPE, and check if it supports biodegradable materials (PLA/PBAT) to meet evolving environmental regulations.

For international trade, the machine must carry a CE Certification for the European market or meet UL standards for North America. Key safety features should include emergency stop buttons, protective covers for heating zones, and overload protection for motors. Always verify that the electrical components (PLCs, Inverters) are from reputable brands like Siemens, Schneider, or Delta to ensure global maintenance availability.

Look for machines equipped with inverter-controlled motors and ceramic heaters, which can reduce energy consumption by 20-30%. Ask the supplier for the kilowatt-hour per kilogram (kWh/kg) ratio. A lower ratio indicates better economic feasibility over long-term production cycles.

Request a live video factory audit or a third-party inspection (such as SGS or BV) during the Fat (Factory Acceptance Test) phase. Ensure the contract specifies that the final payment is contingent upon a successful trial run using your specific raw material pellets.

Focus on the Total Cost of Ownership (TCO) rather than just the sticker price. Negotiate for the inclusion of critical wear parts (heaters, thermocouples, air rings) for the first two years of operation. For bulk orders or production lines, aim for a 5-10% discount or an upgrade to higher-precision components at the same price point.

Confirm the Incoterms (typically FOB or CIF) and ensure the machine is packed using vacuum plastic film and strong wooden crates to prevent sea-salt corrosion. Verify if the supplier provides overseas installation services or detailed video installation guides and remote PLC debugging support.

Utilize Secured Trading Services provided by reputable platforms like Made-in-China.com to protect your payment. Avoid direct transfers to private accounts; always use corporate bank accounts verified by the platform to ensure the safety of your funds.
