Smithers provides label, print and decorated surfaces durability testing as part of its consumer product packaging performance testing services. This testing helps manufacturers assess whether labels, print and decorated surfaces will maintain their adhesion, appearance and functionality throughout storage, handling and use, identifying potential weaknesses before they affect packaging performance.

Testing capabilities include label adhesion and retention, print and colour durability, resistance of decorated surfaces to product exposure, and label legibility, readability and barcode verification. These assessments provide evidence to help manufacturers evaluate packaging materials and suppliers, support quality control, and investigate potential performance issues.

Assessing label and decorated surface adhesion

Poor adhesion can cause labels, print or other decorated surfaces to lift, peel or become damaged during handling and use. Smithers can assess the adhesion and retention of packaging labels and decorated surfaces to help manufacturers determine whether they will remain securely attached during storage, handling and use.

Testing capabilities include:
  • Cross hatch testing to assess the adhesion of decorated surfaces using a tape test
  • Label retention testing to evaluate whether labels remain securely attached
  • Packaging decoration resistance to product exposure to assess the impact of product contact on decorated surfaces
These assessments can help identify adhesion or resistance issues before they affect packaging appearance, essential information or usability.

Evaluating print and colour durability

Print and colour can be exposed to repeated handling, rubbing and other conditions that may affect their appearance or performance. Smithers can evaluate the resistance and durability of packaging print and colour to help manufacturers determine whether decorated surfaces will maintain their appearance through handling and use.

Testing includes:
  • Ink rub testing to assess resistance to rubbing and abrasion
  • Colourfastness testing of packaging materials
Results can support packaging development and material selection where maintaining print quality and appearance is important.

Protecting essential packaging information

Labels and printed information need to remain sufficiently clear and readable throughout the packaging lifecycle. Damage, fading or loss of print can affect packaging usability by making product identification details, usage instructions and safety warnings difficult to read or interpret.

Smithers offers label legibility and readability assessments, together with barcode verification, to help determine whether critical printed information remains clear, readable and suitable for its intended purpose throughout use.

Identifying potential packaging performance issues

Testing can help manufacturers investigate existing packaging performance issues or assess how labels, print and decorated surfaces are likely to perform under expected conditions. By assessing these elements against relevant performance requirements, Smithers can help identify potential weaknesses and provide evidence to support decisions on packaging materials, decoration and design.

Smithers can work with you to develop an appropriate testing programme based on the packaging format, materials, decoration and intended application.

Standards and customised testing

Smithers performs label, print and decorated surfaces durability testing using recognised ASTM and ISO methods alongside customised test protocols designed around specific packaging formats, materials and performance requirements.

Relevant methods include ASTM D3359, ASTM D5264, ISO 15415 and ISO 15416. Where standard methods do not fully reflect the intended application, customised evaluations can be developed to assess label, print and decorated surface performance under relevant conditions.

Supporting confident packaging performance decisions

As part of Smithers' Consumer Product Packaging Performance Testing service, label, print and decorated surfaces testing provides independent evidence of how these elements perform under relevant conditions. Our expertise helps manufacturers identify potential weaknesses and assess whether packaging meets their performance requirements.

Whether you are developing new packaging, investigating a performance issue or evaluating existing packaging components, Smithers can help identify the testing needed to assess label, print and decorated surface durability as part of your wider packaging performance requirements.
