An L-Bar Sealer & Shrink Tunnel is an integrated shrink wrap machine designed to streamline your packaging process. Shrink wrapping involves using heat-sensitive films to encase products, followed by the application of heat to shrink the film, forming an airtight and secure package around your items. This system typically consists of two main components:
Our heat sealing machines and heat shrink machines are perfect for both small and large-scale operations, ensuring your packaging needs are met with precision and speed.
Our heat sealer employs a low voltage impulse sealing system controlled by PLC and a micro-processor, ensuring consistent and high-quality seals without creases or tears. This system preserves your product’s graphics and maintains an attractive appearance.
Equipped with product-sensing horizontal and vertical eyes, our shrink packaging machines guarantee superior packing quality. They prevent inconsistent film applications, reduce in-transit movement, and protect against product tampering and damage.
With flexible collating and metering technology, our plastic sealing machines can handle a wide range of packaging goods. Optional multi-stream packaging alternatives, coupled with multi-lane conveyors and infeed rails, enhance efficiency during high-volume packaging runs, achieving speeds of up to 150 cycles per minute.
Our plastic wrap machines feature adjustable, servo motor-powered film splitters compatible with all types of shrink films. This design simplifies film loading and changeovers, eliminating issues with film tension. Additionally, our systems include automatic excess wrapping material collection to reduce waste and prevent clogs.
Constructed with durable stainless-steel, our packaging machines are built to withstand the demands of medium to large-scale operations, ensuring longevity and minimal downtime.
L-Bar Sealers are versatile and widely used in various industries for:
These heat wrap machines are ideal for packaging small to medium-sized goods, including:
Our heat sealing machines are designed for high-speed, heavy-duty use. Positioned in front of the shrink tunnel, L-Bar Sealers use soft feed conveyors to transport products into the system. Guides ensure each product is correctly positioned within the shrink film.
The L-Bar Sealer features an adjustable sealing arm with two sealing bars in an inverted L shape, also known as an impulse sealer. This mechanism automatically wraps products in a shrink film bag before the heating element seals and cuts the film pouch in a single motion.
Once sealed, the products are transferred to the heat shrink tunnel, where the film uniformly shrinks around each item, providing a secure and professional finish.

An L-Bar Sealer & Shrink Machine is a packaging system used to seal products in shrink film and shrink the film tightly around the product using heat. The L-shaped sealing bar cuts and seals the film before the product passes through a shrink tunnel.
L-Bar sealers are suitable for packaging:
Food products (bakery items, ready meals, confectionery)
Retail and promotional packs
Cosmetics and personal care products
Stationery and printed materials
Industrial and FMCG items
They are ideal for single items or multipacks.
L-Bar Sealer & Shrink Machines commonly work with:
PVC
POF (Polyolefin)
PE (Polyethylene)
Film selection depends on product protection, appearance, and environmental requirements.
L-Bar Sealers seal two sides of the pack in one motion and are ideal for small to medium production volumes.
Side Sealers are designed for higher speeds and longer products, sealing continuously on one side.
L-Bar sealers offer simplicity, flexibility, and cost-effectiveness.
Production speed varies based on automation level and operator handling. Typical output ranges from 10 to 40 packs per minute, making it suitable for small to medium production runs.
L-Bar systems are available in:
Manual
Semi-automatic
Fully automatic configurations
The right option depends on production volume and labour availability.
