Adhesives for paper and board, packaging and disposable sanitary products - Determination of blocking behaviour of potentially adhesive layers

This European Standard specifies a method for the determination of blocking behaviour of thermoplastic or hygroscopic layers or coatings of potentially adhesive surfaces. Some potentially adhesive surfaces are both thermoplastic andhygroscopic. The method described provides a means for determining, on the same surface, both thermoplastic and hygroscopic blocking.

Klebstoffe für Papier, Verpackung und Hygieneprodukte - Bestimmung des Blockverhaltens von klebfähigen Schichten

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Blockverhaltens von thermoplastischen oder hygroskopischen Lagen oder Schichten aus klebfähigen Werkstoffen fest. Einige potentiell klebfähige Oberflächen sind sowohl thermoplastisch als auch Hygroskopisch. Dieses Verfahren gibt die Möglichkeit, das thermoplastische und hygroskopische Blockverhalten am selben Werkstoff zu bestimmen.

Adhésifs pour papier et carton, emballage et produits sanitaires jetables - Détermination du comportement au blocage de couches potentiellement adhésives

La présente méthode spécifie une méthode pour la détermination du comportement au blocage des revêtements ou couches hygroscopiques ou thermoplastiques de matériaux potentiellement adhésifs. Certains matériaux potentiellement adhésifs sont à la fois thermoplastiques et hygroscopiques. La présente méthode permet d'évaluer, sur la même surface, le comportement au blocage à la fois thermoplastique et hygroscopique.

EN 12702:2000 - Adhesives for paper and board, packaging and disposable sanitary products - Determination of blocking behaviour of potentially adhesive layers

Overview

SIST EN 12702:2000 is a European Standard published by CEN that defines a method for determining the blocking behaviour of potentially adhesive layers on paper and board, packaging materials, and disposable sanitary products. This standard focuses on assessing thermoplastic or hygroscopic coatings or layers that may exhibit adhesive properties causing unwanted sticking or blocking. SIST EN 12702:2000 is essential for manufacturers and quality control laboratories aiming to ensure product performance and handling safety by evaluating the resistance of coated surfaces to blocking under various conditions.

Key Topics

  • Blocking Behaviour Determination
    The standard details a test method to measure the tendency of coated surfaces to stick together when in contact, especially for thermoplastic or hygroscopic adhesive layers.

  • Thermoplastic and Hygroscopic Layers
    SIST EN 12702:2000 addresses surfaces that can exhibit blocking either due to thermoplastic properties (softening with heat) or hygroscopic characteristics (absorbing moisture), including layers that show both behaviours simultaneously.

  • Test Procedure and Conditions
    It specifies controlled test conditions to replicate real-life scenarios such as pressure, temperature, and humidity, which impact blocking behaviour.

  • Surface Compatibility
    Suitable for determining blocking properties on paper, cardboard, packaging materials, and disposable sanitary products where adhesive coatings are used.

  • Quality Control Application
    Enables manufacturers to identify blocking risks and improve surface treatments and coatings for enhanced performance.

Applications

SIST EN 12702:2000 is widely applicable in industries relying on coated paper-based materials and flexible packaging solutions, including:

  • Paper and Board Manufacturing
    Helps verify the quality of adhesive layers used in paper products, reducing handling issues and product damage during storage or transportation.

  • Packaging Industry
    Ensures packaging films and cartons coated with adhesive layers do not block or stick together, maintaining packaging integrity and usability.

  • Disposable Sanitary Products
    Assesses the blocking risk of surfaces in hygiene products such as diapers and sanitary pads to improve user comfort and product handling.

  • Coating Development and Evaluation
    Useful for R&D teams formulating thermoplastic or hygroscopic coatings to balance adhesive properties while minimizing blocking.

  • Quality Assurance Laboratories
    Standardizes testing procedures to maintain consistent product quality and compliance with industry best practices.
