In-Mold

Advantages and Disadvantges of Injection Mold

Advantages of Injection Mold

• Lower cost than other other labelin methods.
• No extra labeling step or post labeling, just ’’fill & seal’’.
• Higher packaging line speed.
• In-house container inventory is either reduced or eliminated and warehousing shifted to molders,
  that makes ‘’JIT’’ delivery possible.
• Light weight of containers, because label displaces synthetic granulate equal to own volume (gram weight of granulate savings of 10-15%).
• Better appearance and durability
• Significant reduction in label defects by application.
• Resistant to product staining
• Improvement of side wall strength of a container up to 120%
• The label becomes a part of bottle or container, therefore it allows bottle to flex and be squeezed without label separation.
• Best performance of labeling, because IM-IML is a part of a container wall. It cannot be peeled off as a PS or glue-on label can.

Disadvantages of Injection Mold

• Higher tooling cost in addition of ‘’pick and place’’ robotic mechanism and label magazine.
• Longer set-up time compared to blow modling machines and increase in scrap and labour time
• Frequent changes in tooling decrease economical advantages. It requires longer runs.
• Unexpected order run reduction trhough the retailer can leave unusable container in stock and increase of order run causes to use PS label, because IML production for short run is very expensive and lead time is longer than PS labels.
