Bulk Material Repackaging: Big-Bag to Bags

Bulk material repackaging screening at SMIALA terminal

At a Glance

Bulk material repackaging converts trade packaging (big-bag to 25 kg bags or octabins) without changing the material itself. SMIALA handles up to 50 tonnes per day. ISO 9001:2015.


What is bulk material repackaging?

Bulk material repackaging is the conversion of trade packaging format without altering the material’s composition or quality. Common operations at SMIALA:

  • Big-bag (1000 kg) → 25 kg bags — for customers needing small portions or manual dosing
  • 25 kg bags → big-bag — consolidation of multiple small batches into one bulk transport unit
  • Big-bag → octabin (200–400 kg) — intermediate format for automated filling machines in factories

Why factories need repackaging

Most PE and PP granulates arrive in Europe in big-bags inside sea containers — the most cost-effective transport format. However, end-user factories often cannot use big-bags directly:

Automated filling machines — many injection moulding, extrusion and blow moulding machines have hoppers designed for 25 kg bags; big-bags require adapters or are incompatible.

Recipe weighing — composite production requires precise component weighing; 25 kg bags make manual portioning practical.

Rack weight limits — standard pallet racking holds 500–800 kg per location; 25 kg bags on a pallet is the safe and standardised solution.

Customer requirements — many buyers in Germany, Austria and Switzerland require delivery in 25 kg bags with specific label formats.

Screening before repackaging

On request SMIALA screens material by fraction before repackaging. Appropriate mesh size is selected per material specification. Separated fines are collected separately; many clients resell these as secondary material. Screening results are documented in the batch protocol.

Labelling and traceability

Every package produced during repackaging is labelled with: material name, batch number, net/gross weight, repackaging date, customer barcodes (EAN, GS1-128, QR) on request. Traceability is built into the ISO 9001:2015 documentation system.
