L-sealers are essential packaging machines designed to wrap products in shrink film, providing a clean and professional finish. At Pactur, we manufacture a complete range of L-sealers, including manual and semi-automatic models, all built in Italy with precision, durability, and user-friendly controls. For automatic L-sealers, please visit our dedicated page.

What Is an L-Sealer?

An L-sealer uses two perpendicular sealing bars, forming an “L” shape, to enclose a product in shrink film. After sealing, the product passes through a heat tunnel that shrinks the film tightly around it. This process ensures tamper-proof packaging with an attractive appearance. L-sealers are widely used in food packaging, cosmetics, media, electronics, publishing, and logistics.

Types of Pactur L-Sealers

• Manual Models – Compact, affordable, ideal for startups and small-scale packaging operations.
• Semi-Automatic Machines – Designed with pneumatic arms for better speed and ease of use.

Main Advantages

• Custom-built in Italy with industrial-grade steel frames
• Easy-to-use touchscreens and programmable settings
• Clean and reliable sealing with minimal maintenance
• Compatible with different shrink films (polyolefin, polyethylene)
• Optional integration with conveyor belts and robotic packaging lines

Industries That Benefit from Pactur Shrink Wrapping Systems

Whether packaging cosmetics, printed materials, baked goods, or electronics, Pactur’s sealing systems adapt to any sector. L-sealers are frequently used in:

• Food and bakery industries
• Publishing and printing houses
• Pharmaceutical and cosmetic sectors

Choosing the Right L-Sealer

Manual machines are perfect for those who pack occasionally and need flexibility. Semi-automatic sealers offer the best of both worlds—speed and affordability—while automatic models are best suited for high-volume operations and repetitive packaging tasks.

Semiautomatic L-Sealer Packaging Machines with Pneumatic Sealing Arm

Overview of the Machine

Available Models

Mod. 45/AL2 – 65/A2 – 80/A2 – 110/A2

Semiautomatic L-sealer packaging machines with pneumatic sealing arm and shrink tunnel included. These machines are high-performance and easy to use.

Sealing Arm Controls

The sealing arm is activated by pneumatic piston. Three operation modes are available: dual-button press, foot pedal, and programmable timer. The operator can choose freely among these options.

The sealing movement is completely safe, thanks to a mechanical emergency stop that blocks the descent if needed.

Key Functional Features

Dual Conveyor Belt System

Two independent Teflon mesh belts:

• The first belt operates in the sealing area
• The second belt is inside the shrink tunnel

Once the product is sealed, it is automatically moved to the tunnel for shrinking. Meanwhile, the operator can load the next product.

Independent Sealing and Shrinking

Sealing and shrinking are separate processes, enabling continuous loading and higher productivity.

Work Cycle Settings

Forward-Forward and Forward-Reverse Modes

The standard “forward-forward” cycle moves the product directly through the tunnel. The “forward-reverse” cycle lets the item return to the operator after shrinking.

Use as Sealer Only

The machine can also be used just for sealing, by turning off the tunnel resistances.

Customization Options

Tunnel Height Adjustment

On request, the tunnel hood can be raised to accommodate taller products.

Output Roller Conveyor

Optional output roller conveyor is available for product handling after shrink wrapping.

Semiautomatic L-Sealer Packaging Machines with Manual Sealing Arm

Performing and user-friendly semiautomatic L-sealer packaging machines with manual sealing arm, offered at a very competitive price. The shrink tunnel is positioned at 90° from the product flow direction.

Flexible Operation Modes

The sealing arm is available in both manual version with magnetic control and semiautomatic version with pneumatic piston control.

The machine includes three control methods: buttons, foot pedal, and timer.

Dual Conveyor System for Better Productivity

Equipped with two independent Teflon mesh conveyor belts:

• The first belt moves the product after sealing
• The second belt runs through the shrink tunnel

This system allows sealing and shrinking to happen independently, increasing productivity. While the first product is entering the tunnel, the operator can load the next one.

Smart Sealing and Optional Use

The machine can also be used as a sealing station only, without shrinking. A multiple work cycle setting is available to group packages and increase speed: the first belt activates after a preset number of sealed packs.

Intelligent Sealing System

All models include an electronic control system that adjusts and corrects sealing time automatically for precision and reliability.

Packaging Cycle Options

Packaging can be configured so the product either returns to the operator or exits from the opposite side, depending on layout and workflow.

Available Tunnel Configurations

• Shrink tunnel with Teflon mesh conveyor belt
• Tunnel with metal mesh conveyor belt
• Tunnel with silicone-coated rods

Compact Machines, Great Results

The LADYPACK economic semi-automatic angular packaging machines with manual welding arm are compact but equipped with real shrink tunnels, ensuring high throughput and professional results.

All machines are entirely manufactured in our Bologna headquarters.
