tomatoes

If you’ve spent any time in the kitchen – even if it’s just poking through the fridge looking for leftovers – you’ve probably encountered the orange staining on plastic food storage containers that results from hot tomato-based products (either heated in the container or put away while still warm).

In addition to being unsightly, this staining is also disconcerting from a health perspective: If pigments from the food are seeping permanently into the plastic, it stands to reason that some of the plastic is making its way into the leftover Bolognese, too.

As an amateur home cook, I’ve noticed the discoloration myself, and there is simply no way to remove it. But there is now, thanks to Plasmatreat, a way to prevent it.

Working with a leading industry coating specialist, we have co-developed a durable plasma coating for plastic food storage containers (LDPE, PP, and PET).

In our tests, the stain-resistant coating lasted for at least 100 cycles of freezing, microwave heating, and top-rack dishwasher cleaning. In addition to preventing stains, the coating technology makes plastics safer, with little to no material diffusion from the polymer to the food or liquid stored in them – or vice versa.

Additional treatment applications could include baby bottles and large water storage containers.

This is great news for all of us who care about what we eat and try to keep certain things – such as LDPE! – out of our diets. The process is not yet being used commercially, but I will of course keep you posted.
