Designing for in-mould labeling requires a different mindset than standard label printing. The label must withstand high temperatures (200–300°C) and extreme pressures during the injection moulding process. Key factors include selecting the right film substrate—typically biaxially oriented polypropylene (BOPP) or polyethylene—that matches the container polymer for optimal bonding. Ink systems must be heat-stable and compatible with both the film and the moulded resin. Additionally, the label's dimensional stability is critical; any shrinkage or expansion can cause wrinkling or misalignment in the final product.
