Paperboard vs Polycoated vs Other

I’m having a hard time understanding how a paper box with over print fits into the Oregon’s paperboard categories.

Paperboard-

Definition: Paperboard and fiberboard substrates with no corrugation including but not limited to the following grades: Solid Bleached Sulfate (SBS), Coated Unbleached Kraft (CUK) and Coated Recycled Paperboard.
Examples: Paperboard and boxboard folding cartons such as cereal, tissue and shoe boxes, stiff paperboard used to mount plastic blister packs (e.g., for toys and batteries) and other packaging formats.

Polycoated Paperboard-

Definition: Unbleached paperboard that has a polyethylene (or other plastic) coating or lamination on the inner side of the packaging only, or bleached paperboard that has a polyethylene (or other plastic) coating or lamination on either the inner or outer sides of the packaging or both.
Examples: Bleached polycoated paperboard packaging, and paper cups and bowls provided at quick service restaurants to serve food and beverages; tubs and folding boxes used to package ice cream, frozen foods and other products designed for storage in a freezer; brown paperboard takeout boxes with a polycoated lining on the inside of the packaging.

Other Paper Laminates-

Definition: Laminated paper where paper is the main component, along with either metalized foil, plastic, wax or silicone coating or layer. The paper component represents the greatest percentage by weight of the material.
Examples: Fiber spiral wound containers (with plastic, aluminum or steel bottom and lid) for frozen juice, chips, cookie dough, coffee, nuts, microwavable paper containers (susceptor packaging), wrappers, paper wrap packaging provided with food, such as sandwiches, burgers, or muffins, paper/plastic composite based wrapping paper (excluding gift wrap) and gift bags supplied as service packaging at point of sale, pet food bags, laminated kraft paper bags (filled at point of sale) and laminated kraft flexible paper packaging; any paper laminate wraps supplied to consumers as a product such as parchment paper or wax paper in this category.

If there’s a little bit of foil, does that automatically make it “Other”? Is an over print varnish considered a poly coat?

Have you checked Guidance and Tools for Oregon? I posed this question in today’s webinar but they didn’t get to it. But I suspect if they had, they would have said something like, it is your own individual determination, just make your methodology clear in your report, and when we review it if we don’t like it we’ll get in touch.
Reminds me of in my town, code enforcement won’t tell you what you can and can’t build – they’ll only tell you if you did it wrong. It is a way to protect yourself legally, essentially, by not giving you permission to do it a certain way.
