US-based consumer packaging company Graphic Packaging International (GPI) has announced today a new line of PaperSeal trays as an alternative to modified atmosphere (MAP) and vacuum skin packaging (VSP) plastic trays. Tray-sealing technology specialist G. Mondini assisted GPI in the development of the trays.
According to the company, PaperSeal trays offer a robust and consistent sealing surface that is equivalent in quality to plastic trays. The tray will be sealed hermetically, making it suitable for fresh-produce and frozen foods, and providing up to 28 days of shelf-life.

The trays are made of 80-90% paperboard and 10-20% film depending on the trays dimensions. The film liner is designed to be easily separated from the paperboard to enable easy recycling.
The paperboard is produced using sustainable forest-sourced fibre and aligns with GPI’s 2025 sustainability missions, which includes the aim to reduce low-density polyethylene (LDPE) use by 40%.
Graphic Packaging Europe business development director Paul Tye said: “The transition to fibre-based packaging is a priority for many of our customers, and it’s clear that sustainable paperboard packaging solutions must meet the functionality and performance of existing tray designs.”
GPI and G. Mondini also partnered with UK-based food processor Anglo Beef Processors (ABP) Food Group in order to make the processing and packaging more sustainable.
