Challenges faced during development:

Design constraints to maintain the overall volume of the existing jars.

To maintain the overall ratio of the shapes for both sku’s in available neck sizes of the preforms. With lot of design iterations we finalised 53mm for smaller sku and 63mm for bigger sku.

Minimum wall thickness of the jars were maintained similar to our existing design with lesser Preform weights which was cost beneficial.

Distortion of graphics in the shrink sleeve was a major issue observed during shrink sleeving operation due to the complex intrinsic design of the jar.

New custom-made shrink tunnel was installed for this application. It required extensive validation trials to achieve the desired effects on the shrink sleeve.
