Pressure sensitive labelling on glass containers
Scope of application
This document concerns only self-adhesive labelling on glass containers. The principal objectives of the document are as follows:
- To give manufacturers and users a reference document to help them carry out the operation of self-adhesive labelling and to give guarantees of security for the consumer;
- to determine the specifications of each elements and their interfaces;
- to give to manufacturers and users a reference document for the establishment of technical documents and quality control procedures;
- to facilitate diagnosis in case of malfunctions;
- to indicate what happens at the end of the life of a glass container.

Document under responsibility of working group:
Labelling on glass
WG chair: Arnaud STAIB - CCL Label S.A.S
This joint working group develops guidelines and best practices for the functional specification for labels and application machines on glass packaging, ensuring proper label adhesion and performance, optimising pressure-sensitive labelling processes, and improving label separation in the glass recycling and reuse processes. By bringing together key stakeholders, including adhesive and label manufacturers, glass producers, labelling machine suppliers, and fillers, the group aims to establish documentation that enhances packaging efficiency, sustainability, and overall performance.
