Choosing the right continuous side sealer setup is crucial to maintaining efficiency and product quality. Whether you’re new to packaging automation or upgrading your system, understanding the differences between belt-driven and chain-lugged in-feeds can help you make the best decision.

At the heart of high-speed shrink-wrapping operations, a continuous side sealer ensures neat, secure packages with impressive speed and versatility. Designed for seamless integration, these machines offer flexible packaging solutions without the need for perfectly sized film, handling various product dimensions effortlessly.

What Are the Key Differences Between Belt-Driven and Chain-Lugged In-Feeds?

The type of in-feed system plays a big role in how products move through your side sealer machine. While both setups serve the same purpose—feeding items into the sealing section—their operation styles differ.

  • Belt-Driven In-Feeds: 
    • Use conveyor belts to move products smoothly. 
    • Ideal for lighter, evenly shaped products. 
    • Offers gentle handling and reduced product shift. 
  • Chain-Lugged In-Feeds: 
    • Products are gripped by lugs attached to chains. 
    • Suitable for heavier or irregularly shaped items. 
    • Ensures consistent spacing and alignment. 

Both options offer efficient feeding, but choosing the right system depends largely on the product type and production needs.

How Does a Continuous Side Sealer Improve Packaging Efficiency?

A continuous side sealer creates perfectly trimmed seals on three sides of the product, ensuring a clean, professional appearance. Because the machine operates without stop-and-go movements, it significantly boosts packaging speeds.

Using a continuous motion side sealer, you also benefit from:

  • Handling random product spacing without adjustments. 
  • Saving up to 15% on film material costs thanks to servo motion control. 
  • Reducing downtime by eliminating complex parts like pneumatics and temperature controllers. 
  • Smooth and easy product changeovers without manual programming. 

Unlike traditional models, the modern side sealer machine requires minimal maintenance and no compressed air, making it a smart investment for high-output operations.

Which Industries Benefit Most from Side Sealer Machines?

Many sectors rely on continuous side sealers to maintain their competitive edge. Some of the key industries include:

  • Food and bakery 
  • Wood products and construction supplies 
  • Cosmetics and personal care 
  • Pharmaceuticals and nutraceuticals 
  • Printing, publishing, and logistics 

Manufacturers and contract packaging companies across these industries trust continuous motion side sealers for reliable, high-volume shrink-wrapping.
