Product Details

Product Introduction

Designed for stable, high-throughput pouch production, the Fully Automatic Strip Back Sealing Packaging Machine is a compact vertical form-fill-seal solution built for modern packaging lines. It supports paper/plastic packaging materials and produces neat, consistent pouches with a diagonal straight horizontal seal and a strip-style back sealing structure. With Siemens servo motor heat-sealing bag pulling, PLC-based control, and a touch-screen interface, the machine delivers repeatable bag length control, smooth film tracking, and reliable sealing performance for daily industrial operation. Operating on 220V power, it targets manufacturers seeking an efficient, automated way to package powders, granules, and liquid products into small-format bags within a flexible size range.

Product Advantages

Consistent bag forming and sealing quality

The diagonal straight sealing form helps create clean, uniform seals suitable for a wide variety of pouch styles. Controlled heat sealing and stable film feeding support consistent seal integrity when running packaging film thicknesses from 0.04–0.08mm, reducing the risk of wrinkling, weak seams, or misalignment during continuous production.

Siemens servo bag pulling for accuracy

A Siemens servo motor heat-sealing bag pulling method enables precise indexing and dependable bag length control, helping maintain tight tolerances across long production runs. This improves repeatability from bag to bag and supports a steady output rate with fewer interruptions for readjustment.

Efficient production speed for daily output targets

With a working speed of 20–50 bags per minute (depending on product characteristics, film type, and bag size), the machine supports scalable output for small and medium batch production, while remaining suitable for integration into larger automated lines that require stable rhythm and predictable throughput.

User-friendly operation and process visibility

A touch-screen display provides clear parameter access for temperature, speed, and running status, improving operator control and enabling fast changeovers. The PLC control architecture enhances process stability and helps reduce operator dependency for consistent performance.

Flexible bag size compatibility

The machine supports bag sizes from L50–200mm and W25–150mm, allowing one platform to cover multiple SKUs or packaging formats. This flexibility helps manufacturers respond faster to product line expansions and varying retail pack sizes without replacing the core equipment.

Industrial build for production environments

With an overall machine size of L1500×W1000×H2200mm and an approximate weight of 500kg, the structure is designed for stable operation, reduced vibration, and better long-term reliability in continuous packaging workshops.

Application Fields

Food and beverage packaging

Suitable for packing free-flowing powders and granules as well as liquid products into small pouches, supporting common retail and sample-size formats where stable sealing and consistent bag appearance are required.

Daily chemical and household products

Supports pouch packaging for liquid or granular household items where controlled bag pulling and reliable seals help prevent leakage and reduce product loss during transport and storage.

Pharmaceutical and health-related products

Applicable for pouching powder or granular products that benefit from repeatable bag dimensions and stable machine operation, assisting manufacturers in maintaining consistent packaging presentation across batches.

General industrial and OEM/ODM packaging lines

Works well in contract packaging environments that handle multiple SKUs, thanks to its broad bag size range, 0.04–0.08mm film compatibility, and adjustable operating parameters for different materials and product characteristics.
