Does HPP increase plastic leaching?

No, HPP does not increase plastic leaching between food and its packaging.

The European Food Safety Authority (EFSA) identified temperature—not pressure—as the primary factor influencing transfer in packaging. Because HPP is a non-thermal process performed at low temperatures, it does not increase transfer.Scientific evaluations reviewed by the EFSA found that packaging materials exposed to High Pressure Processing remained well below established safety limits.

When food is stored in any type of packaging—plastic, glass with coatings, metal cans with linings, or composite materials—there can be a very small amount of transfer simply because the food and the packaging are touching. This is not unique to plastic, and it does not mean the packaging is unsafe. All of our packaging is food-grade, meaning the materials are tested to meet regulatory safety standards, and the packaging quality is unaffected by HPP.
