TASK:

CHALLENGES:
• Make the jar neck compatible with standard aluminium cap
• Come up with jar design that would seem like glass
• Ensure that oily marinade does not leak from the inside
SOLUTION:
⦁ Customized preform with glass-like neck was engineered
• A number of different jar visualizations were produced and the customer chose the best design for them
• Induction sealing was proposed as an added safety measure
TECHNOLOGY USED: FlexBlow2.
