Expanded polypropylene (EPP) is currently high in demand. The packaging industry is also increasingly relying on this advantageous plastic material as it offers low weight, reusability and a service life of up to ten years, among other benefits. However, labeling EPP is a challenge: its low surface energy repels liquids – including adhesives. Only a few adhesives with special properties are able to adhere to this material.
3M has developed special labeling systems for low surface energy plastics that achieve permanently reliable results. They combine a pressure-activated adhesive with a highly conformable, easily printable 3M polyolefin film. For printing purposes, 3M’s Durable Resin Ribbon 92904 is recommended if the material is regularly exposed to aggressive chemicals or mechanical abrasion.
