This required testing of each different layer of materials that our design required, different fabric weights, different liner microns and materials.
It also required a detailed analysis of the specific chemical make up of each layer of material with all raw material ingredients identified, in what proportion, what brand and statements from each raw material supplier regarding both the actual ingredients and a huge list of prohibited ingredients.
This also required some very specific testing to be completed regarding the migration level of some specific chemicals in each of the layers of material and also included light transmission testing.
All test reports are available on request.
Liner Barrier Properties:
BHNZ’s EVOH liner was tested at Gunn Lab Australia a testing facility well known to the Australian Dairy Industry.
It is a 5 layer liner and achieved the following Oxygen and Water Vapor Barrier test results.
The Oxygen transmission target is 10 or less BHNZ’s liner achieved 2.1
The Water Vapour transmission target is 6.5 or less BHNZs liner achieved 2.6 and 2.3
BHNZ’s designs liner material transmission properties and sell prices have now allowed for a cost effective range all featuring EVOH liner materials.
