Test method for peel properties of flexible composite plastic materials
1 Scope
This document describes the test method for peel properties of flexible composite plastic materials.
This document is applicable to the determination of peel load and/or peel strength of various flexible composite materials in which plastic is laminated to plastic or to other substrates (such as aluminium foil, paper, fabric, etc.).
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies.

GB/T 17200-2008, Rubber and plastics — Tensile, flexural and compression testing machines (constant rate of traverse) — Specification
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
delaminated layer
The layer separated from a flexible composite plastic material.
3.2
substrate
The general term for the layers of a flexible composite material other than the delaminated layer (3.1).
4 Principle
A specimen of specified width is separated at a specified speed, and the peel load and/or peel strength between the delaminated layer and the substrate is measured.
5 Test equipment
5.1 A Class 1 constant-rate-of-traverse testing machine complying with GB/T 17200-2008 shall be used.
5.2 The test equipment shall measure and record the peel load and/or peel strength.
5.3 The centre points of the two grips of the testing machine shall lie on the tensile axis. The front edges of the grips shall be at right angles to the tensile axis, and the gripping surfaces shall lie in the same plane. The grips shall hold the specimen without slipping, and the surfaces shall be smooth and flat so as not to damage the specimen. The grip width shall not be less than the specimen width.
5.4 In the case where specimens are wrapped with backing materials (such as paper, felt, leather, plastic or rubber sheets, etc.), if the specimen cannot be held securely with plane grips, textured grips shall be used.
6 Test specimens
6.1 Specimen dimensions
Rectangular strip specimens shall be used. The standard specimen length is 200 mm, and the width dimensions and tolerances are given in Table 1.
6.2 Number of specimens
Not less than 5 specimens per group.
6.3 Specimen preparation
6.3.1 Pre-separate the delaminated layer from the substrate along the length direction of the specimen for a distance of 50 mm.
6.3.2 If the layers cannot be separated by mechanical means, immerse about 20 mm of one end of the specimen in a suitable solvent for treatment. After removal, wipe off the solvent from the specimen surface and then perform the pre-separation operation.
6.3.3 For specimens that cannot be separated by either mechanical means or solvent immersion but require peel process testing, the specimen shall be pre-treated in accordance with the method in Annex A.
