The Effects of Using Release Liners in Automatic Labeling Equipment

With the continuous advancement of industrial automation, automatic labeling equipment has become an indispensable component of modern manufacturing and packaging. As a key auxiliary material in labeling systems, release film plays a decisive role in improving labeling efficiency, stability, and product quality. This article will provide an in-depth analysis of release film's basic characteristics, its specific role in automatic labeling equipment, common problems and solutions, and how to select high-performance release film. This will help companies better utilize this material and improve overall production efficiency.

Basic Characteristics and Structure of Release Film

Differences between Release Film and Release Paper

Both release films and release paper are release materials. Their differences lie primarily in their base materials, physical properties, and applications:

Release films use plastic films such as PET, PP, or PE as their base materials, offering greater heat resistance and tensile strength.

Release paper uses kraft paper or glass cardboard as their base materials, offering lower costs but lower flexibility and transparency.

Typical Structure of Release Film

A high-performance release film typically consists of three layers:

Base layer: Provides mechanical support, commonly made of materials such as PET and BOPP;

Coating layer: Coated with a silicone or fluorine-based release agent to control release force;

Functional coating (optional): Such coatings as antistatic and waterproof layers enhance the user experience.

Evaluation Indicators for Release Performance

Advantages of Release Liners in Automatic Labeling Equipment

Achieving High-Speed, Precise Labeling

Automatic labeling equipment requires extremely high speed and lamination accuracy. Release liner, with its low peel force and high flatness, ensures smooth label peeling and accurate application, avoiding label drift and deviation.

Ensuring Label Deformation

Due to the tension control system in the automatic labeling process, uneven substrate thickness or excessively soft material can cause the label to stretch and deform during peeling. High-tension PET release film maintains stable deformation even at high speeds, protecting the label.

Improving Equipment Compatibility

High-quality release liners offer high dimensional stability and consistent surface tension, making them compatible with a variety of labeling equipment, including rotary, linear, flat labelers, and round bottle labelers.

Reducing Maintenance Costs

Poor-quality release liners are prone to cracking, warping, or adhesive residue, which can affect labeling machine operation. Using high-quality release liners can extend equipment life and reduce maintenance downtime.

Common Release Linear Problems and Solutions in Automatic Labeling

Excessive Peel Force Affects Labeling

Problem Symptoms: Labels cannot be peeled off smoothly, easily get stuck, or are ejected continuously.

Solution: Replace release liners with lower peel force ratings; select products with a uniform release agent coating; and calibrate the peel angle of the labeling equipment.

Surface Static Electricity Accumulation Causes Label Offset

Problem Symptoms: Labels are not centered and exhibit sticking and offset.

Solution: Use release liners with antistatic coatings; install static eliminators in-line; and select PET release liners to minimize static electricity accumulation.

Wrinkles in the Release Liner Affect Label Neatness

Symptoms: Wrinkles or bubbles appear after label application.

Solution: Replace the substrate with a higher stiffness, such as PET film with a thickness of 50μm or greater; ensure stable temperature and humidity in the labeling environment; and check the tension control accuracy of the unwinding system.

How to Select a High-Performance Release Liner Supplier?

Supplier's Technical Capabilities and Testing Standards

It is more reliable to choose a release liner supplier with its own coating lines and fully automated testing equipment. Revolve CF, a professional supplier of release paper and film, has over ten years of industry experience and is committed to providing high-precision, customized solutions.

Select Product Parameters Based on the Application Scenario

Different automatic labeling equipment has different requirements for release liners. If you need to apply anti-counterfeiting labels, electronic tags, or freezer labels, the following parameters should be used:

Customizable Specifications and Composite Coatings

High-quality release liner suppliers should support customization in thickness, width, peel strength, and coating type, and even offer composite products such as double-sided release liners to accommodate specific process requirements.

Conclusion: Improving Labeling Efficiency Starts with Choosing the Right Release Liner

Release liner is an essential component of automatic labeling systems, directly impacting product appearance, production efficiency, and equipment stability. When optimizing labeling processes, companies should not only improve the performance of the equipment itself but also focus on the compatibility and quality stability of consumables. As a leading domestic supplier of release liners and mold release materials, Revolve CF offers high-performance release liners based on various PET, BOPP, and PE substrates. These films are widely used for labeling in the food, pharmaceutical, daily chemical, logistics, and electronics industries.
