Case Study: Enhancing Release Consistency for an Industrial Adhesives Producer

Executive Summary

We recently partnered with a leading UK industrial adhesives manufacturer to address inconsistencies in release performance during high-pressure bitumen extrusion. Through the development of a high-temperature coated release paper with optimised surface tension, we delivered measurable improvements, including a 6 % reduction in material failure rate, a 20 % increase in liner life, and significantly improved coating transfer quality. This project demonstrates our capability to engineer precise, performance-driven coated papers for technically demanding industrial processes.

Background & Challenge

Our client operates multiple extrusion lines producing bituminous and adhesive materials for use in construction and industrial applications. These production environments require release liners that perform consistently under extreme temperature and pressure conditions.

Their existing liner material was causing several operational challenges:

• Variable release force at elevated temperatures
• Occasional surface transfer to the adhesive coating
• Reduced liner durability, leading to unplanned downtime

The client approached us seeking a more stable, heat-resistant liner that could maintain performance consistency while improving overall line efficiency.

Our Solution

Our technical team began with a detailed evaluation of the client’s extrusion process — analysing temperature gradients, pressure cycles, coating formulations, and peel-force characteristics.

From this assessment, we developed a bespoke high-temperature coated release paper designed to deliver stable, repeatable performance. The final specification featured:

• Optimised surface tension for reliable release under high compression
• Enhanced thermal resistance to maintain coating integrity at process temperatures
• Refined coating distribution for controlled adhesion and uniform release behaviour
• Dimensional stability to prevent deformation during reel unwinding and rewinding

All paper coating and conversion were carried out at our Nottinghamshire facility, ensuring consistency, traceability, and quality control throughout production.

Implementation

We conducted a three-week production trial across two of the client’s extrusion lines, closely monitoring release force, liner handling, and surface integrity under operating conditions.

Our technical specialists collaborated directly with the client’s production engineers to evaluate:

• Coating transfer quality
• Release uniformity under pressure
• Liner durability and fatigue resistance over multiple cycles

The results demonstrated consistent coating stability and reliable release performance, confirming the liner’s suitability for full-scale production.

Results

Following implementation, the client achieved clear operational benefits:

These gains underline how carefully engineered release liners can drive measurable efficiencies in high-pressure adhesive manufacturing.
