Large size container linear blow molder
Optimize your large-scale production of containers with a solution designed to streamline operations, integrating seamlessly into existing processes and ensuring precise, consistent output for a variety of applications across multiple product sizes and specifications.

Produces Large PET Containers Efficiently
The SFL BIG and SFL MAXI from SIPA are linear blowers designed for the efficient production of large size PET containers ranging from 12 to 30 liters. These machines are integral to production lines in industries such as beverage and chemicals, seamlessly transforming preforms into diverse containers. They offer an automated, continuous operation process that starts with preform feeding, followed by precise thermal conditioning, and culminates in consistent stretch-blowing to form the final product. Capable of handling up to 3,000 bottles per hour, these blowers reduce operational costs due to their energy-efficient design. The equipment features advanced software control systems with a user-friendly interface, enabling tight integration and real-time monitoring within your factory’s existing infrastructure. Built for reliability and accessibility, these compact units offer quick mold changeovers and easy maintenance setups, ensuring minimal downtime. The SFL series supports both returnable and one-way containers, making it a versatile choice for producing water cooler bottles, beer kegs, oil drums, and more in large, medium, and small scales. Customization options and engineering support from SIPA ensure the machines meet specific production requirements.
