High Speed Doypack Zipper Pouch Packing Machine Automatic Bag Filler Sealer for Protein Powder

The High Speed Doypack Zipper Pouch Packing Machine is a specialized packaging system purpose-built for pre-made stand-up pouches with zipper reclosable features. This machine is the preferred choice for manufacturers of protein powders, nutritional supplements, meal replacements, and other high-value powdered products that require dust-free filling and secure resealable packaging. The integrated zipper opening and sealing mechanism ensures that each pouch maintains its reclosable functionality, enhancing consumer convenience and product freshness.

Dust-Controlled Filling System: The machine is equipped with a servo-driven auger filler that delivers exceptional accuracy (±0.5-1% of target weight) while minimizing dust generation — a critical requirement for protein powder and fine flour applications. An optional dust collection hood and nitrogen purging system can be incorporated to further protect product integrity and extend shelf life. The filling nozzle is designed with a retractable mechanism that reduces powder fall distance, preventing powder accumulation on seal areas.

High-Speed & Precision: Operating at speeds of up to 70 cycles per minute, this machine features an advanced servo motor control system that synchronizes pouch handling, filling, zipper opening, and sealing operations with millisecond precision. The PLC-based HMI allows for recipe storage of up to 100 different product parameters, enabling rapid changeovers and consistent batch-to-batch quality. Each cycle includes automatic reject of mis-opened or improperly filled pouches, ensuring only perfect packages reach the downstream conveyor.

Construction & Compliance: All product-contact components are manufactured from food-grade stainless steel (SUS304 or higher), with smooth surfaces that are easy to clean and sanitize. The machine meets international food safety standards, including CE, FDA-compliant materials for food contact, and GMP guidelines for supplement manufacturing. Optional upgrades include checkweigher integration, metal detection, and automatic case packing for end-to-end automation. This machine delivers a compelling return on investment for producers seeking to scale up from manual to automated packaging.
