HJ Eco® Ultra-Moisture-Barrier (UMB) Heavy-Duty PE sacks

HJ Eco® UMB is a PPWR-compliant mono-PE packaging solution specifically developed for highly moisture-sensitive products. It offers a recyclable alternative to conventional, non-recyclable aluminum foil–based multi-material structures, with minimal compromise in performance. The structure is engineered by laminating HJ Eco® VMPE - specially developed metallized PE blown film substrates - onto heavy-duty PE blown films. This robust construction ensures excellent mechanical strength, enabling the packaging to withstand demanding handling conditions, including rigorous free-drop testing. In terms of barrier performance, HJ Eco® UMB delivers moisture protection comparable to aluminum foil laminates at room temperature. Even under elevated temperature and high humidity conditions, it maintains a consistently high moisture barrier, with only minimal performance reduction.
