L Sealers and Shrink Tunnels

L sealer shrink wrapper machines are used to create a bag of heat sensitive shrink film around products. With an optional adjoining Shrink Tunnel to then apply heat to the bags, shrinking and tightening the film will provide strong, high clarity and protection. Semi Automatic L-Sealers are a perfect medium volume shrink packaging solution and are able to wrap up to 15 packs per minute in eco friendly shrink films such as our SPR Polyolefin with 30% recycled content.

Frequently Asked Questions

An L-sealer can typically process up to 12 packs per minute, depending on the size of the product and the operator’s experience. This makes it an excellent choice for medium-volume production lines that need consistent, high-quality shrink wrapping. The process is quick, reliable, and produces clean seals that give a professional finish. When paired with a shrink tunnel, output efficiency improves even more, allowing continuous production with minimal manual handling. Many businesses use L-sealers for food, cosmetics, printed materials, and retail products. With straightforward operation and low maintenance needs, they provide great value and productivity for companies seeking efficient, semi-automatic shrink packaging without investing in a fully automated system.
Yes, shrink tunnels can generate some noise during operation, mainly due to the internal fans and heating elements that circulate hot air to shrink the film evenly. However, the sound level is generally moderate and similar to other packaging machinery in a production environment. Most operators find the noise manageable, especially when the machine is positioned in a standard work area or production line. Many modern shrink tunnels are designed with noise reduction in mind, using insulated panels and quieter fans to minimise disruption. With proper setup and routine maintenance, a shrink tunnel runs smoothly and efficiently, ensuring high-quality results while keeping noise levels at a comfortable, safe level for daily operation.
L-sealers and shrink tunnels are designed to work with a variety of films, most commonly polyolefin and polythene. Polyolefin is known for its exceptional clarity and strong, professional finish, making it ideal for retail presentation. It’s also food-safe and durable. Polythene, on the other hand, provides extra strength and protection, making it suitable for heavier or bulkier products that need more resilience. The versatility of these films allows operators to package everything from small items to large boxes. Both materials seal cleanly and shrink evenly when used with the right temperature settings. Choosing the correct film ensures smooth operation, minimal waste, and a secure, attractive wrap that enhances product appearance and protection during transport.
Yes, L-sealers and shrink tunnels can be run efficiently by a single operator, particularly when fitted with a return conveyor. This setup allows the operator to load products, monitor sealing, and remove finished packs from one workstation, streamlining workflow and reducing labour requirements. The design of most L-sealer systems focuses on simplicity, ensuring safe and user-friendly handling. Adding a return conveyor not only improves efficiency but also maintains a smooth production rhythm. This makes L-sealer and tunnel combinations ideal for small to medium-sized businesses looking to maintain productivity with minimal staffing. With the right setup, one person can comfortably manage the entire shrink-wrapping process while maintaining professional results.
No, an L-sealer and shrink tunnel system does not typically require a compressed air supply. These machines are designed to operate using electric power alone, which makes installation easier and maintenance simpler. Without the need for an air compressor, setup costs are lower and the workspace remains quieter and more efficient. This also reduces the risk of downtime related to air pressure issues. The heating and sealing elements are powered electrically and can be controlled accurately for consistent results. This all-electric design makes L-sealers and shrink tunnels more practical and versatile for a wide range of production environments, providing reliable performance without the complexity of pneumatic connections or additional equipment.
Yes, second-hand L-sealers and shrink tunnels are often available from trusted suppliers like Sontex. Buying refurbished or used packaging machinery can be a cost-effective way to expand production capacity without investing in new equipment. All second-hand machines offered by reputable suppliers are typically tested, serviced, and guaranteed to ensure safe and reliable operation. These units often perform to the same high standards as new models, making them ideal for businesses wanting proven performance at a reduced cost. Whether you’re looking for a manual, semi-automatic, or fully automatic setup, quality pre-owned machines can deliver excellent results and longevity when maintained properly. Always purchase from recognised suppliers to ensure full support and spare parts availability.
