Blow/fill/seal system for aseptic liquid packaging
Achieve efficient aseptic packaging with a system that combines blow molding, precise servo-controlled filling, and sealing, helping you streamline production while maintaining sterility of liquid products.

Blow Molds, Fills, and Seals Liquid Products
The ASEP-TECH® Model 640 from Weiler Engineering, Inc. is a high-speed packaging machine that excels in blow/fill/seal processes for liquid applications. This machine is particularly effective for industries such as pharmaceuticals, biotech, and nutraceuticals, addressing the need for efficient, sterile packaging. It supports a broad range of container sizes, from 0.2mL to 1000mL, making it versatile for products like sterile saline injectables and single-dose eye drop units. Designed for integration into complex production lines, the Model 640 offers servo-controlled fill motion and optional isolation insertion, enhancing its operational flexibility. With a stepped-base design, it simplifies maintenance and changeovers, minimizing downtime. The machine handles up to 18,000 containers per hour depending on design and product characteristics, with an emphasis on energy efficiency through optimized servo controls. This ensures lower operational costs while maintaining high throughput. Compliant with GMP and other regulatory standards, the Model 640 also offers customization options to meet specific user requirements and support from Weiler’s engineering team.
