Mixed results for Jokari dishwasher durability tests.
Matthew found no signs of 'peeling, ware, or damage' of Jokari labels after many times through a commercial dishwasher.
Andy found 1 of the 3 labels he tested to fail during a residential dishwasher cycle on tupperware lids.
I have scheduled time for case testing with a commercial dining (conveyor belt) dishwasher later in the week for comparisons.
Adhesive waterlock Puracycle patent describes a water-tight seal formed between the label and container to prevent water or sanitizer from interacting with the label at sharp, high-force angles, and instead lowering interaction forces via a sloped adhesive interface.
