Product Introduction
The Motor Crank Type Heat-Sealing Bag-Pulling Packaging Machine is an automatic form–fill–seal solution engineered for continuous, stable, and high-speed production. Built around a horizontal sealing structure with encoder-coordinated bag pulling, it integrates bag forming, metered filling, heat sealing, and pattern cutting into one streamlined workflow. The system supports packaging of particles, powders, and liquids (subject to product flowability and packaging requirements), covering a practical filling range of 50–500 ml for daily manufacturing needs.
Designed for composite packaging films such as BOPP/PE, the machine delivers consistent film tracking and dependable sealing quality to help reduce rejects and material waste. A heavy-duty 600 kg frame improves operating stability, while key electrical components from Schneider or OMRON and a JULONG photoelectric tracking eye enhance control reliability and repeatability. Whether used for single-product lines or multi-SKU operations, this model offers a balanced combination of output efficiency, seal integrity, and format flexibility.
Product Features
Stable Horizontal Heat-Sealing for Strong, Uniform Seals
The horizontal sealing unit is designed to maintain steady pressure and temperature control for consistent package integrity. A straight-pattern seal with 2 mm spacing and a 10 mm sealing width helps improve leak resistance, seal aesthetics, and transport durability—supporting reliable performance in demanding production environments.
Material Versatility for Particles, Powders, and Liquids
With configuration options aligned to different product characteristics, the machine can be applied across a wide range of packaging tasks—from granular foods and seasoning blends to powders and certain liquid products. This adaptability supports manufacturing plants that need one platform to cover multiple product types and packaging goals.
Encoder-Controlled Bag Pulling for Repeatable Length Accuracy
The motor crank type heat-sealing bag-pulling mechanism uses encoder feedback to coordinate sealing action and film movement. This improves repeatability in bag length control and helps maintain consistent package dimensions across long production runs. Measurement accuracy is typically within ±1% to ±10%, depending on material properties and fill quantity.
Flexible Bag Size Range to Support Multi-SKU Production
Bag width can be adjusted from 50 to 150 mm, and bag length from 30 to 240 mm, allowing efficient switching among different pack formats. This flexibility reduces reliance on multiple dedicated machines and shortens changeover time when managing diverse SKUs.
Production-Ready Construction with Hygienic Contact Surfaces
Product-contact parts are made from Stainless Steel 304 to enhance corrosion resistance, hygiene, and long-term durability. The rigid machine body improves vibration control at higher speeds, supporting stable sealing pressure and consistent film handling during continuous operation.
Accurate Film Tracking and Reliable Electrical Integration
The JULONG photoelectric eye provides dependable mark detection and film positioning for printed film applications. Combined with Schneider or OMRON electrical components, the system offers robust control stability, reducing unplanned downtime and improving overall equipment effectiveness in daily production.
Easy-Tear Options for Better Consumer Convenience
An independent easy-tear device enables point-shaped easy-tear or double easy-tear designs, improving opening convenience without sacrificing sealing strength. This feature is especially valuable for retail-ready packages where user experience and package integrity are equally important.

Application Fields
This automatic bag forming, filling, sealing, and cutting system is well-suited for production lines that require stable sealing quality and repeatable packaging performance using composite films. Typical applications include food processing (granules, seasoning powders, mixed powders, sauces and similar fillings), chemicals (powders and small-particle materials), and pharmaceutical-related packaging scenarios where consistent package integrity and controlled operation are essential. With adjustable bag sizes, reliable tracking, and easy-tear functionality, it supports both standardized mass production and flexible multi-SKU packaging workflows.
