PE Coated Paper Bowls: Practical Use Cases | Bioleader® Insights

Large full-coverage artwork increases ink coverage and makes production stability more important. In Bioleader®’s manufacturing experience, certain offset full-coverage cup projects have a greater practical risk of rubbing or color transfer between tightly nested cups. For this reason, flexo is often evaluated first for high-coverage cup and bowl designs.

PLA-coated projects may support more than one printing route depending on the exact product structure and factory setup. The supplier should confirm compatibility between the coated paper, printing process, forming method and required artwork before production.

Yes, suitable PE-coated paper cup projects may use either flexo or offset depending on the manufacturer’s equipment, artwork, order quantity and converting route. Buyers should confirm the printing process before final artwork separation and plate making.

Flexo uses a flexible raised plate to transfer ink directly to the paper, while offset transfers the image from a plate to a rubber blanket and then to the paper. For paper cups, the better method depends on coating type, printing area, colors, quantity and production route. Water-based coated cups in Bioleader®’s current production system normally use flexo.

The PE film is very thin and transparent. The natural kraft color of the paperboard remains visible through the coating. A slight gloss or smoother surface indicates the transparent barrier film, but the inside does not need to become white.
