Control Panel

Allows convenient adjustment of sealing temperature, conveyor speed, and operating parameters for different packaging requirements.

Heating & Sealing System

Continuously heats and seals the bag opening as it passes through the sealing section, providing a consistent and secure seal.

Conveyor Belt

Continuously transports packaged products through the sealing process for efficient production.

Adjustable Bag Guide

Guides bags into the sealing section and helps maintain proper positioning during continuous conveying.

Dual-Motor Synchronized Control

A reduction motor and stepper motor work together to synchronize the upper and lower mechanisms, ensuring stable operation during continuous sealing.

Why Choose the ZONESUN ZS-LWC350L?

✅ Dual-Motor Drive — Stable Synchronized Sealing & Conveying: Unlike a conventional single-drive configuration, the ZS-LWC350L uses a reduction motor + stepper motor to synchronize the upper sealing mechanism and lower conveyor, improving stability during continuous sealing.

✅ Continuous Band Sealing — Designed for Continuous Production: The sealing system continuously transports, heats, presses, and seals the bag opening, making it more suitable for continuous production than single-cycle sealing equipment.

✅ 0–15 m/min Sealing Speed — Flexible Production Control: Adjustable sealing speed allows operators to match machine operation to different compatible bag materials and production requirements.

✅ 100–1000 mm Sealing Height — Suitable for Different Bag Sizes: The sealing section can be vertically adjusted across a 100–1000 mm range, providing greater flexibility when changing package formats.

✅ 30/50 kg Heavy-Duty Conveyor — Built for Large Filled Bags: The conveyor is designed to support 30/50 kg loads, making the machine suitable for heavy filled bags and larger packaged products.

✅ Up to 1000 × 800 mm Bags — Large Package Compatibility: According to the supplied specifications, the machine supports compatible bag sizes up to 1000 × 800 mm × 0.02 mm, making it suitable for industrial large-bag packaging applications.

✅ 0–300°C × 2 Temperature Control — Adaptable Sealing Parameters: Sealing temperature can be adjusted according to different compatible heat-sealable bag materials and production requirements.

✅ 10 mm Sealing Width — Consistent Band Seal: The standard machine provides a documented 10 mm sealing width for secure continuous sealing of compatible packaging materials.

✅ Adjustable Bag Guide — More Stable Bag Positioning: Adjustable guides keep the bag properly aligned with the sealing mechanism during conveyor movement, helping improve sealing stability.

✅ Control Panel — Convenient Parameter Adjustment: Operators can conveniently adjust sealing temperature, conveyor speed, and other operating parameters according to different packaging requirements.

✅ Vertical Bag Sealing — Keep Products Upright: The vertical machine structure is particularly suitable for filled bags containing loose products such as grains, powders, pet food, and fertilizer that should remain upright during sealing.

✅ Optional Wider Sealing Width — Customizable for Packaging Requirements: A wider sealing configuration can be selected when the standard 10 mm seal does not meet the customer's packaging requirements.

✅ Optional Coding & Printing — Sealing and Coding in One Process: Optional steel-wheel printing, ribbon coding, standard inkjet printing, and high-performance inkjet printing allow production information to be added during the sealing process.

Ideal Applications

Rice Bags: Suitable for continuous vertical sealing of filled rice bags where the package needs to remain upright during processing.

Grain Bags: The heavy-duty conveyor and vertical structure make the machine suitable for compatible grain packaging.

Flour Bags: Suitable for heat-sealable flour bags within the documented size and load ranges.

Powder Packaging: Can be used for compatible powder-filled bags requiring upright continuous heat sealing.

Pet Food Bags: Suitable for larger and heavier pet food packages requiring continuous sealing.

Fertilizer Bags: The 30/50 kg conveyor load capacity makes the machine suitable for compatible heavier fertilizer packages.

Chemical Product Bags: Can be used for compatible heat-sealable chemical packaging bags.

Food Ingredient Bags: Suitable for industrial food ingredient packaging requiring continuous bag sealing.

Large Filled Bags: Particularly suitable for larger packages because of the adjustable sealing height and heavy-duty conveyor.

Heavy Packaged Products: Supports filled packages within the specified 30/50 kg conveyor load capacity.

Different Bag Heights: The 100–1000 mm adjustable sealing range provides flexibility for different packaging formats.

Continuous Production Lines: Suitable for production environments where bags need to be continuously conveyed through the sealing station.

Sealing + Coding Applications: Optional coding and printing devices allow date, batch, or other compatible production information to be added as part of the packaging process.
