What we like about PulpWorks: They’ve developed a unique molded pulp blister pack. They also did some interesting work with freeze-protection and food coatings.
Pulp Blister Packs
A paper alternative to plastic backings on blister packs.
-
Like plastic blister packs, these paper-based alternatives are made of two trays, connected with a hinge. Molded pulp feels like paper based trays that you may have received with takeout.
-
Paper is lightweight in shipping and can be engineered for structural stability with flat pack shipping.
Molded pulp trays take the biggest sustainability hit when it comes to energy requirements, because they typically require high heat to dry in manufacturing.
PulpWorks claims that their trays and blister packs are compostable, but we haven’t seen a certification.
PulpWorks says that their trays and blister packs are made from molded paper waste or agricultural waste including bagasse, bamboo, switch grass, and wheat straw.
All of these plants sequester carbon, which is ultimately released back into the air at the paper's end of life when it biodegrades or is composted or incinerated.
-
Molded pulp trays and blister packs are recyclable with paper. In fact, the best afterlife for most paper products — from collateral to boxes — is recycling. Most paper fibers can be recycled more than five times. Paper with tape or stickers can still be recycled, because non-paper materials are sifted out in the recycling process.

-
Molded paper trays may have multiple color options, but printing can be limited due to the texture and of the surface. You can also add designs or branding within the mold of your tray for an emboss or deboss effect.
Printed designs will match the finish of the paper. For a shiny finish, you’ll need to inquire about added coatings. Coatings may also be necessary if your packaging needs extra water resistance.
