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.

Typ­ic­al areas of application

• Pack­aging industry: Inspec­tion of films, bags, blisters
