Automatic Pouch Filling & Sealing Machine (4–8mm Back Seal / 8–10mm Horizontal Seal)
Designed for continuous, high-efficiency sachet production, this automatic pouch filling and sealing machine integrates dosing, film forming, pulling, sealing, and cutting into one stable packaging platform. It is engineered to run composite packaging films such as BOPP/PE and produce clean, uniform back-seal pouches with consistent length control and reliable seal integrity. A motor-crank heat-sealing bag-pulling structure, coordinated by encoder feedback, keeps pulling and sealing synchronized to minimize misregistration and improve pouch appearance. With a multi-column output architecture and practical configuration options such as easy-tear features and leak-proof sealing lines, the machine supports a wide range of products from free-flowing liquids to powders and granules, helping manufacturers scale output while maintaining repeatable quality under industrial operating conditions.
Product Features
Encoder-synchronized sealing and pulling: The motor-crank heat-sealing pulling mechanism is paired with encoder control to stabilize sealing timing and pouch length, reducing deviations caused by film stretch or speed fluctuation.
Strong compatibility with composite films: Optimized for flexible laminates commonly used in consumer packaging (e.g., BOPP/PE), delivering dependable sealing performance and barrier protection suited to daily-use products.
Multi-column productivity without sacrificing consistency: Supports 4–12 columns (defined by pouch size), enabling high throughput for small-volume sachets while keeping each lane’s forming and sealing uniform.
Enhanced horizontal sealing structure: Horizontal sealing uses a single-sided diagonal mesh pattern with 1mm spacing to reinforce seal strength and improve visual consistency; an optional 1mm leak-proof line is available for liquid applications to reduce sealing risk.
Improved consumer usability: An independent easy-tear device supports point-shaped easy-tear or double easy-tear mouth designs, enabling cleaner opening and better end-user experience.
Hygienic, durable build: Product-contact areas are manufactured in SUS304 stainless steel to enhance corrosion resistance and meet higher hygiene requirements in food, daily chemical, and healthcare environments.
Stable output for diverse materials: Depending on dosing system selection and product characteristics, the machine can package liquids, powders, and granules within a small-dose range while maintaining dependable forming and seal quality.

Application Industries
This machine is built for manufacturers that require consistent dosing and stable sealing in small-volume sachet packaging. With appropriate dosing and feeding systems, it is suitable for liquids such as juices, functional drinks, liquid medicines, detergents, and other flowable products—especially when configured with the leak-proof line option for higher sealing safety. It is also applicable to powders and granules used in food, daily chemical, pharmaceutical, and healthcare categories. Typical use cases include portion packs, trial-size samples, and single-serve consumer formats within the 1–50 ml range, where multi-column production helps increase capacity while maintaining uniform pouch formation and professional pack presentation.
