Materials Supply

Pre-consumer HDPE. Clean, consistent, ready to work.

Unused bottle cap stock and shredded HDPE, color-sorted and packed to consistent specs. Factory-fresh material for bottlers, makers, and fabrication shops.

Why MLAB materials

Pre-consumer HDPE is only useful if it's consistent, clean, and documented. We built the sort, clean, and labeling process around those three things.

Color-sorted, batch-tracked

Every pound is labeled with its blend and production batch. Reorders match, and custom blends stay reproducible.

Clean & dry, ready to press

Materials arrive washed and moisture-controlled. Skip the prep step and go straight from bag to heat press.

Sustainable by default

Every pound is factory-surplus HDPE diverted from disposal. Clean, consistent, and never touched a consumer — plus a take-back program for your finished goods.

Direct from the shop floor

Custom blends and unusual requests route straight to the person packing your order. No sales intermediary.

How it's made

From post-consumer caps to packed and labeled stock, here's what every pound goes through before it leaves the shop.

01

Source

Unused bottle cap stock arrives clean from manufacturers and distributors — material that would otherwise be landfilled or destroyed.

02

Shred

An industrial shredder reduces the caps to consistent, uniform flake sized for pressing, molding, and extrusion.

03

Pack

Materials are color-sorted, weighed, labeled by blend and batch, and packed for shipping anywhere in the US.

Who uses this material

Pre-consumer HDPE works for everything from bottler feedstock to maker-shop projects. These are the audiences we regularly ship to.

Bottlers

Manufacturers blending pre-consumer cap stock back into production batches. Color-sorted, consistent, ready.

Makers

Hobbyists and independent fabricators pressing their own sheets and molded parts.

Studios & shops

Limited-run product studios and fabrication shops sourcing consistent pre-consumer stock.

Maker-spaces

Community shops running workshops, experiments, and material demonstrations.

Education

K–12 and university programs teaching material science, sustainability, and circular manufacturing.
