Product Overview
This Motor Crank Type Heat-Sealing Bag-Pulling Packaging Machine is an automatic plastic bag sealing and filling solution designed for stable, high-speed production with a horizontal sealing structure. It supports packaging of particles, powders, and liquids (subject to packaging requirements), with a fill range of 50–500 ml. Featuring precise encoder-controlled sealing action and a robust 600 kg machine body, it helps manufacturers standardize bag formation, filling, sealing, and cutting in one streamlined process. The machine is compatible with composite packaging films (e.g., BOPP/PE) and is engineered for consistent seal quality, efficient output, and reduced material waste across daily continuous operation.
Product Advantages
Reliable Horizontal Sealing for Consistent Package Integrity
The horizontal sealing system delivers stable sealing performance with a straight-pattern seal design. With a sealing width of 10 mm and 2 mm spacing, it helps create uniform seals that improve leak resistance and overall package appearance.
Wide Material Adaptability for Multi-Industry Use
Designed to handle particles, powders, and liquids, the machine can be configured to meet different product characteristics and packaging goals. This versatility makes it suitable for diverse production lines where packaging formats and materials may vary.
Accurate Operation with Encoder-Controlled Bag Pulling
The motor crank type heat-sealing bag pulling mechanism uses an encoder to control sealing action, supporting repeatable bag length control and improved packaging consistency. Measurement accuracy ranges from ±1% to ±10% depending on product type and filling quantity.
Flexible Bag Size Range for Multiple SKUs
The bag-making range supports widths from 50 to 150 mm and lengths from 30 to 240 mm, enabling flexible switching between packaging specifications and helping reduce the need for multiple dedicated machines.
Production-Ready Construction and Component Selection
Material-contact parts use Stainless Steel 304 to improve hygiene and durability. The system integrates well-known electrical components (Schneider or OMRON) and a JULONG photoelectric tracking system to support stable control and reliable film positioning.
Convenient Easy-Tear Options for Better User Experience
To improve consumer usability, the machine supports point-shaped easy-tear or double easy-tear designs, enabled by an independent easy-tear device, helping enhance product convenience without compromising seal strength.

Application Industries
This automatic bagging and sealing system is suitable for manufacturers requiring reliable forming, filling, sealing, and cutting of plastic bags using composite films. Typical application fields include food processing (granules, seasonings, powders, sauces), chemical products (powders and small-particle materials), and pharmaceutical-related packaging scenarios where stable sealing quality and repeatable operation are essential. The machine’s adaptable material handling, adjustable bag size range, and easy-tear functionality make it a practical choice for multi-SKU production and standardized packaging workflows.
