Stand Up Pouch Sealing Machine for Fish Feed 25 Bags/Min

25 bag/min Zipper Bag Sealing Machine Product Introduction 

The fish feed zipper bag sealing machine is designed for efficient sealing of stand up pouches and zipper bags used in aquaculture and pet feed packaging. It is suitable for sealing pellet feed, granules, and other dry products, ensuring airtight packaging and maintaining product freshness.

This machine adopts advanced heat sealing technology and continuous conveying system, providing stable sealing performance and consistent output. With a capacity of up to 25 bags per minute, it is ideal for small to medium production lines.It is widely used in fish feed factories, pet food processing plants, and agricultural product packaging industries.

Working Principle：

The machine operates using a continuous heat sealing process.Filled zipper bags or stand up pouches are placed on the conveyor and automatically transported through the heating zone. The heating elements apply controlled temperature and pressure to seal the bag opening.

After sealing, the cooling system quickly solidifies the seal to ensure strength and airtight performance. The sealed bags are then discharged through the conveyor for collection.This process ensures stable operation, uniform sealing quality, and high efficiency in production environments.
