Wall thick­ness mea­sure­ment – pre­ci­sion for qual­i­ty, sta­bil­i­ty, and sustainability

Wall thick­ness deter­mines the sta­bil­i­ty, tight­ness, and func­tion of pack­ag­ing. With the Magna-Mike 8600, we mea­sure films, bags, and blis­ters pre­cise­ly in the ear­ly stages of devel­op­ment — up to 9.14 mm, con­tact-free, and accredited.

Why wall thick­ness mea­sure­ment is crucial

Even slight devi­a­tions in wall thick­ness can have a mas­sive impact on the qual­i­ty of pack­ag­ing:
Leaks, reduced strength, or exces­sive mate­r­i­al con­sump­tion are com­mon con­se­quences.
That is why pre­cise wall thick­ness con­trol is a cen­tral com­po­nent of qual­i­ty assur­ance, release test­ing, and process optimization.

Mea­sur­ing prin­ci­ple: Hall effect for high-pre­ci­sion results

Our mea­sure­ments are based on the Hall effect:
A small, non-mag­net­ic ball is posi­tioned on one side of the test spec­i­men, and a mag­net­ic probe on the oth­er.
The exact wall thick­ness is cal­cu­lat­ed from the dis­tance between the ball and the probe – even for com­plex geome­tries such as bags, films, or blisters.

Two ball sizes cov­er the entire mea­sur­ing range up to 9.14 mm and ensure max­i­mum accu­ra­cy.
After cal­i­bra­tion, we doc­u­ment each result dig­i­tal­ly – includ­ing a test cer­tifi­cate for com­plete traceability.

Accred­it­ed qual­i­ty accord­ing to ISO/IEC 17025

Wall thick­ness mea­sure­ment with the Magna-Mike 8600 is part of our accred­it­ed test­ing port­fo­lio.
This means that the results meet the high­est stan­dards of accu­ra­cy, trace­abil­i­ty, and inter­na­tion­al com­pa­ra­bil­i­ty.
Our test­ing sys­tems are reg­u­lar­ly val­i­dat­ed and cal­i­brat­ed to ensure long-term mea­sure­ment quality.
