Among the various shrink wrapping systems available, the continuous side sealer stands out for its ability to package products of varying lengths with high-speed precision. This guide explores the ideal scenarios for using a continuous side sealing machine, how it compares to other systems like L-sealers or sleeve wrappers, and what makes it the preferred solution for high-volume packaging lines.

Key Advantages of Continuous Side Sealers

• Continuous packaging flow: no interruptions between product cycles
• Supports variable product lengths: especially useful for long or non-uniform items
• Superior aesthetic quality: clean, tight seals on all sides
• Efficient film usage: no excess plastic around the product

Applications and Industries

Pactur’s continuous side sealer machines are designed to package medium to large products with shrink film in a continuous flow. Their ability to handle variable lengths makes them ideal for:

• Boxes and cartons in logistics and e-commerce
• Printed materials like catalogues and books
• Cosmetic and pharmaceutical kits
• Food trays and multipacks
• Home appliances and hardware bundles

Comparison with Other Shrink Wrapping Machines

Unlike traditional L-sealers that stop between cycles, a continuous side sealer enables a fully automated flow. Compared to sleeve wrappers, it offers a completely closed film envelope and a higher-quality seal.

When Is It the Right Choice?

• You have a high production rate
• Your products vary significantly in length
• You need excellent aesthetics with minimal film waste

It’s particularly effective in the food, cosmetics, publishing, and hardware sectors.

From May 27 to 30, 2025, during the international packaging exhibition IPACK-IMA in Milan, Pactur will officially present its latest innovation: the semi-automatic 45/A2 LINE shrink wrapper. This compact and versatile machine is designed to optimize packaging processes by combining a sealing arm and shrink tunnel in a single in-line unit. As the smallest model in the LINE range, it inherits the successful structure of the 65/A2 LINE and adapts it to space-conscious production environments. With an in-line layout and easy operator access, the 45/A2 LINE offers performance, efficiency, and reliability in an all-in-one format.

This new model represents a significant advancement in shrink-wrapping technology, combining efficiency, compactness, and versatility.

Compact Design and Linear Workflow of semi-automatic 45/A2 LINE shrink wrapper

The 45/A2 LINE introduces an innovative layout with a right-to-left workflow, allowing for easier installation in confined spaces and optimizing operational efficiency. The shrink tunnel is integrated inline with the sealer, reducing the machine’s overall footprint and improving accessibility for operators.

Advanced Technical Features

• Automatic Electromechanical Sealing Arm: ensures precision and reliability without the need for compressed air.
• Three Control Modes: buttons, pedal, and timer, to adapt to various production requirements.
• Teflon Conveyor Belts: two independently adjustable belts for continuous and synchronized product flow.
• Compatibility with Various Films: suitable for PO and PVC films without the need for modifications.
• Sealing Dimensions: 450 x 340 mm, ideal for small to medium-sized products.

Innovation and Pactur Tradition

The 45/A2 LINE continues Pactur’s tradition of delivering reliable and cutting-edge packaging solutions. Following the success of the medium-size 65/A2 LINE model, the 45 LINE meets the needs of companies requiring a compact machine without compromising on quality and performance.

An Opportunity Not to Be Missed

The unveiling of the 45/A2 LINE at IPACK-IMA offers a unique opportunity to explore the capabilities of this new packaging machine. Visitors can witness live demonstrations and engage with Pactur experts to delve into technical features and potential applications.

AUTO 40 UNICA is Pactur’s automatic packaging solution for soaps, equipped with robotic Pick & Place loading and high-performance L-sealers.

Shrink wrapping machines are essential in the industrial packaging process. They apply a thermoplastic film around the product, which is then heat-shrunk to perfectly fit its shape. The integration of robotic lines enhances this process in terms of efficiency, precision, and flexibility.

Why Use Robotic Lines with L-Sealers?

• Robots automate loading/unloading, reducing downtime and increasing productivity.
• Advanced sensors detect product position and ensure perfect alignment in the L-sealer.
• Versatility: easily handle different SKUs and formats with minimal adjustments.

The AUTO 40 UNICA is particularly suitable for fast-moving consumer goods such as soap bars. The robotic arm picks products from the line and places them directly into the sealing area.

Benefits of the Pactur L-Sealers

• Servo-assisted movement for consistent sealing performance
• Integrated tunnel with precise temperature control
• Compact, monoblock design with reduced footprint
