L Sealers and continuous shrink-wrapping systems are widely used across the packaging industry to deliver clean, secure, and professional-looking presentation packaging. If you’ve ever seen a product wrapped in a thin, clear film that hugs the box – you’ve likely seen the result of one of these machines in action.
These systems are ideal for secondary packaging, offering protection and tamper-evidence while enhancing shelf appeal. It’s important to note that an L or continuous sealer alone is used to bag the product. A heat tunnel is added to complete the process to achieve a shrink-wrapped finish.
L Sealers – Reliable and Professional Finishing
Also referred to as L-bar sealers or lap sealers, these machines get their name from the L-shaped sealing arm that joins the film around the product. They’re used with flexible polyolefin, PVC, or LDPE films.
Features:
- Sealing Mechanism
The L-shaped heated bar presses down on the overlapping film edges, melting and sealing them together to create a neat and secure seal. - Shrink Tunnel Compatibility
After sealing, the product moves through a shrink tunnel, where heated air causes the film to shrink tightly around the product, producing a crisp, form-fitting finish. - Efficient Operation
L Sealers are ideal for medium to high-speed applications, offering reliable performance for batch production and intermittent packing lines. - Precision Controls
Many models include digital or programmable settings for sealing temperature, pressure, and dwell time, ensuring that every pack is sealed consistently and carefully.
Continuous Shrink Wrappers – High-Speed, High-Performance
Continuous sealers offer a more automated and streamlined solution for faster production lines or packaging longer items. These machines are designed for speed, volume, and efficiency.
Features:
- Continuous Film Feed
Shrink film is fed from a roll across a sealing frame while products are conveyed. As the film wraps the product, it is sealed into a bag before entering the shrink tunnel. - Shrink Tunnel Integration
The sealed product is passed through a heated tunnel where the film shrinks tightly to the contours of the item, providing both protection and presentation. - Product Protection
Shrink wrapping offers excellent moisture, dust, and tampering resistance, making it ideal for both consumer and industrial packaging needs. - High-Level Automation
These systems can include automated infeed conveyors, film unwinders, and discharge belts, streamlining the wrapping process for continuous throughput. - Film Versatility
Compatible with a wide range of shrink films – including polyethene, polypropylene, PVC, and polyolefin – allowing full flexibility depending on your product requirements and desired finish.
