Product Introduction
The Stainless Steel Automatic Bag Filling Machine is a high-efficiency, fully automatic solution that integrates pouch forming, metered filling, and heat sealing in one continuous workflow. Designed for stable multi-lane production, it is ideal for packaging bulk materials such as powders, granules, and selected liquids (depending on dosing configuration). The machine adopts a motor-crank heat-sealing film pulling mechanism, coordinated by encoder-controlled sealing actions, to keep film movement and sealing timing precisely synchronized. This structure helps maintain consistent bag length, reduces deviation during long runs, and supports smooth, repeatable operation across multiple columns. Compatible with composite laminated packaging films, the machine produces clean back seals with an adjustable 4–8 mm width and a pattern-free finish, delivering a neat retail appearance while preserving seal integrity. For improved end-user convenience, an independent tear-notch device can be added to create either a point-shaped easy-tear mouth or a double easy-tear mouth, ensuring quick opening without scissors and consistent notch quality across batches.
Product Features
Full SUS304 Product-Contact Design for Hygiene and Longevity
All parts in contact with product are manufactured from SUS304 stainless steel, offering strong corrosion resistance and reliable performance in demanding production environments. This construction supports hygiene-focused operations and helps minimize contamination risk when handling food ingredients, healthcare powders, and chemical materials. The durable stainless structure also improves long-term stability and simplifies cleaning and maintenance routines.
Motor-Crank Film Pulling with Encoder Coordination for Stable Output
The motor-crank heat-sealing bag pulling system works in coordination with encoder control to precisely match film pulling with sealing actions. By stabilizing pouch forming rhythm and sealing timing, the system improves repeatability, reduces bag-length variation, and enhances overall pack consistency—particularly important for multi-column sachet production where uniformity across lanes directly impacts yield and quality.
Strong, Tidy Sealing with Efficient Pneumatic Horizontal Seal Drive
The machine applies twisted edge adhesive sealing to achieve firm closure while maintaining a clean sealing profile. Back sealing width is adjustable from 4 to 8 mm with a smooth, unpatterned finish, helping branded packaging look professional and consistent. Horizontal sealing is driven by an AirTAC cylinder, delivering steady pressure and repeatable sealing performance to support reliable closure even during high-throughput runs.
Independent Easy-Tear Device for User-Friendly Sachets
To improve consumer experience, the machine supports optional point-shaped easy-tear mouths or double easy-tear designs. The independent tear-notch unit allows controlled notch formation without interfering with main sealing stability, helping keep opening performance uniform across production batches and reducing the likelihood of irregular tearing.
4–12 Column Multi-Lane Architecture for Higher Productivity
Built for multi-column production, the machine can be configured from 4 to 12 columns according to pouch width requirements. This multi-lane structure enables high throughput within a compact footprint, making it suitable for factories producing large volumes of small sachets while maintaining consistent sealing quality and stable machine rhythm. Note that the bag width specification is determined by the selected column configuration and cannot be changed once set.

Product Application Areas
This machine is designed for industries that require high-speed, small-sachet packaging with stable operation and consistent seal quality. In food and beverage production, it supports items such as seasoning powders, drink premixes, instant ingredient sachets, additives, and tabletop sweeteners. In pharmaceuticals and healthcare, SUS304 product-contact construction helps meet hygiene expectations for powdered supplements and single-dose sachets. In chemical applications, it is suitable for fine powders and granules where neat pouch appearance and reliable sealing are essential. With multi-column scalability, composite film compatibility, and optional easy-tear functionality, the system fits both industrial packaging needs and retail-ready sachet manufacturing where seal integrity and user-friendly opening are critical.
