ASTM D6252/D6252
ASTM D6252/D6252M is a test to measure peel strength at 90 degrees of pressure-sensitive label adhesion. The test tells the force needed to remove a label from a designated test surface when applied to various controlled conditions. PLS are used in packaging, logistics, pharmaceuticals, food, and consumer goods applications, where the adhesive properties are of utmost importance as a quality parameter. The standard is useful for the manufacturer to assess the ability of the label to stick to a substrate while still offering the balance wanted in terms of holding, without compromising the ability to remove the label. Presto Laboratories offers advanced peel adhesion testing solutions that support accurate label performance evaluation according to ASTM D6252 requirements.
Significance
Label peel adhesion is one of the most critical label attributes, which directly impacts the functionality, appearance, and consumer experience of the product. The adhesive strength of labels is an issue that can cause labels to lift, wrinkle, or detach during handling and transportation, or be so tightly adherent that they require excessive effort for removal and cause scuffing on the package surface. ASTM D6252 assists manufacturers in comparing adhesive formulations, attaining production consistency, and determining whether or not a label will adhere satisfactorily to a particular product. Test results are used to support quality control programs, packaging development, and material selection. Consistent peel adhesion testing also helps industries maintain labeling quality and reduce product-related issues in the marketplace. Scope This test method (ASTM D6252/D6252M) is for determining the peel adhesion strength of pressure-sensitive labels in a 90-degree peel test. The measurement is based on the force needed to remove a label at a controlled rate from a substrate. It is applicable to a wide variety of pressure sensitive labels and adhesive systems used in commercial and industrial applications. The standard provides a uniform procedure for generating repeatable and comparable adhesion data under laboratory conditions.
