White corrugated project sheets

Flipside Products 32300-25 sheets are bright white matte corrugated boards measuring 20 x 30 inches. Each pack contains 25 new sheets designed for signs, posters, photo mounting and art projects. The front surface accepts markers, crayons, paint and adhesives. The reverse side shows a brown kraft finish.

Suits classrooms and crafters

Teachers, students and hobbyists who need a lightweight yet sturdy board for presentations or creative work will find these sheets practical. They trim cleanly with a knife or razor for custom sizes. Buyers who need a different colour, a non-corrugated surface or a smaller pack should look elsewhere.

Handles markers and paint

The matte front takes marker, crayon, paint and adhesive without bleeding through under normal use. Corrugated construction resists bending and creasing better than standard posterboard. Very wet media or heavy structural loads may exceed the board’s capacity. Pack of 25 gives ample supply for multiple projects.

Questions about this item

What adhesives work with the white matte surface?

The bright white matte surface works well with standard craft adhesives such as glue sticks, white glue, and spray adhesive for signs, posters, and photo mounting.

Can I keep using my existing 20 x 30 frames with these sheets?

Each board measures 20" x 30", so it fits the same frames and mounts you already use for standard posterboard of that size.

How do I know the corrugated core is intact after cutting?

Trim with a knife or razor; the corrugated core should stay flat without creasing, and the brown kraft back remains smooth for a professional finish.
