Treofan EPT BOPP film for IML in thermoforming

Treofan EPT is a BOPP film developed for in-mould labeling in thermoforming that delivers a similar look and feel to injection-moulded products. The solution features a surface that enables stable fusing of thermoforming and label film at comparatively low temperatures and pressures, allowing the benefits of deep drawing to be harnessed without compromising quality.

Deep drawing — or thermoforming — is an increasingly popular alternative to injection moulding for certain product groups, partly due to potential economies of scale. Until now, however, attaching BOPP labels to thermoformed products has required a separate process step; as temperatures and pressures used in thermoforming are much lower than those in injection moulding, direct fusion is not possible.

The company has developed a surface that attaches to deep-drawn films under the conditions typically used for thermoforming. The resulting join between container and label is visually and functionally near-indistinguishable from the complete fusion achieved by injection moulding.
