GB/T 22638.7-2016Test methods for aluminium and aluminium alloy foilsPart 7: Determination of heat seal strength (English PDF)

Foreword

GB/T 22638 "aluminum foil test method" is divided into 10 parts. - Part 1. Determination of thickness; - Part 2. Detection of pinholes; - Part 3. Detection of adhesion; - Part 4. Determination of surface wetting tension; - Part 5. Detection of wettability; - Part 6. Determination of DC resistance; - Part 7. Determination of heat seal strength; - Part 8. Determination of texture content; - Part 9. Hydrophilic testing; Part 10. Determination of the surface density of the coating. This part is part 7 of GB/T 22638. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part of the replacement GB/T 22638.7-2008 "Aluminum foil test method Part 7. Determination of heat sealing strength". With GB/T 22638.7- 2008, the main technical changes are as follows:

--- The scope of application of the standard has been modified to "solid drugs (tablets, capsules, etc.)" modified "blister";

--- increase the normative reference documents;

--- modified the principle of the method;

--- "test reagents and equipment" modified to "reagents and materials" and "equipment and equipment"; - Removed the standard test carrier;

--- increased the tensile testing machine precision requirements;

--- modified the sample requirements;

--- modified the coating surface and coating requirements;

--- modified after the test piece heat sealing time;

--- modify the value of the pull value. This part is made by China Nonferrous Metals Industry Association. This part is the national nonferrous Metals Standardization Technical Committee (SAC/TC243).

1 Scope

GB/T 22638.7-2016 is the Chinese national standard on test methods for aluminium and aluminium alloy foilspart 7: determination of heat seal strength, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 December 2016 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2017. Classification: ICS 77.040.01, CCS H20. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

GB/T 22638 of this part of the provisions of the blister packaging aluminum foil heat sealing strength of the method of determination of the principle of reagents and materials, equipment With equipment, samples and test pieces, determination, results calculations and test reports. This part is suitable for aluminum foil and polyvinyl chloride (PVC), polyvinylidene chloride (PVDC) and other hard pieces made of foam blister packaging aluminum Determination of heat sealing strength of foil adhesive layer.
