Polymer sourcing for storage boxes and crates

Stackable lidded boxes for household and light-industrial storage. PP and HDPE dominate; UV stabilisation matters for garden and outdoor SKUs.

Recommended polymers

Polypropylene
PP
Versatile commodity polyolefin. Highest European production volume after PE. Homopolymer, random and impact copolymer grades cover injection, extrusion, fiber, film.
High-Density Polyethylene
HDPE
Linear polyethylene with density above 0.941 g/cm³. Used for blow-molded bottles, pressure pipes, and rigid containers.

Key requirements

  • Drop impact at sub-zero temperatures (cold-storage and outdoor SKUs)
  • Lid-clip retention through 1,000+ open/close cycles
  • Stackability under static load (60–80 kg per stack)
  • Pigmentation and label/print compatibility for retail SKUs

Procurement notes

PP impact copolymer (MFI 8–25) is the workhorse for cold-storage and indoor units. HDPE blow-grade is often used for budget outdoor and garden boxes — typically with carbon-black masterbatch for UV protection. The European market is led by converters like Curver, Keter, and SmartStore who source via long-term direct contracts with Borealis, LyondellBasell, and SABIC. Spot buyers running smaller volumes go through Resinex or Albis for distributor stock.
