Some thought and design considerations must accompany a project for creating an IML Barrier container. Simply adding a Barrier IML Label to an existing product design can result in barrier property loses that are not expected.
- The container must be designed so that two labels can meet, overlap and seal a vast majority of the container surface. The containers must be designed following some specific rules.
- The bottom of the container must be designed for complete coverage with attention to the radii.
- The stacking shoulder design must accommodate label adhesion, without causing potential cracks in the label.
- The dummy mandrel must be designed to allow for complete overlap of the two labels.
- Label transfer must be designed to handle stiffer labels that have a tendency to curl.
- Features must be added to the mold which facilitate label overlap and complete sealing of the container surface.
- The IML system must have extremely tight label placement accuracy. Muller has the experience, know-how and expertise under one roof for product design, label die-line, mold design and IML system technology to achieve highest barrier levels.
