SIST EN 1896:2001

Overview

EN 1896:2001 defines a laboratory test method for determining the tensile strength and elongation of dry films of adhesives used on paper and board, primarily for packaging and disposable sanitary products. The standard applies to both hot melt and dispersion adhesives and specifies that adhesive films are stretched to breakage at a constant pulling speed to measure mechanical performance.

Key topics and requirements

• Scope and materials: Test applies to dry adhesive films formed from hot melt or dispersion formulations applied to or cast from solutions for paper and board applications.
• Test principle: Films are elongated at a constant pulling speed until breakage; the resulting values for tensile strength and elongation at break are recorded.
• Specimen handling: The standard covers requirements for preparing and handling dry adhesive films and test specimens prior to testing.
• Measured outputs: Primary results are tensile strength (force at break relative to specimen cross-section) and elongation (percentage or ratio of extension at break).
• Reporting: Test reports typically include specimen description, adhesive type (hot melt or dispersion), test conditions, pulling speed, and measured tensile and elongation values.

Note: EN 1896:2001 focuses on the test method concept and required measurements; it does not prescribe formulation or product acceptance limits.

Applications

• Quality control of adhesives used in packaging materials (e.g., corrugated board, carton laminations).
• Performance testing for adhesives in disposable sanitary products (e.g., tapes, nonwoven bonding).
• R&D for adhesive manufacturers optimizing hot melt or dispersion formulations for strength and flexibility.
• Comparative testing in procurement to verify suppliers’ claims about tensile and elongation performance.

Who uses EN 1896:2001

• Adhesive manufacturers and formulators developing hot melt or dispersion systems.
• Packaging converters and board manufacturers validating adhesive performance on paper substrates.
• Manufacturers of sanitary disposable products assessing bond-line film properties.
• Independent testing laboratories and quality assurance departments performing standardized mechanical tests.

Related standards

• Other CEN and international standards cover complementary adhesive tests such as peel strength, shear strength, adhesive coating application, and conditioning/test environment. Users often apply EN 1896 alongside these tests to get a complete mechanical profile of adhesive performance.
