PE/PP Polymer Import from Asia: Container to Silo Trailer Cross-Docking
The SMIALA terminal in Chorula, near Opole — 4 km from the A4 motorway on the Hamburg–Poland–Ukraine corridor — serves importers of polyethylene (PE) and polypropylene (PP) granulate from Asia, Korea and China. We receive sea containers directly from port, gravity-transload big-bags into silo trailers and dispatch cargo to factories in Poland, Germany, Austria and the Czech Republic. Throughput: up to 200 tonnes per day. Lead time from order: 24–48 hours.
The importer’s problem: container waiting at port, factory waiting for material
PE/PP granulate arrives in Europe in sea containers (20’ or 40’ HC) filled with big-bags. A container from South Korea (LG Chem, Lotte Chemical, Hanwha) takes 25–35 days to reach Hamburg, Gdansk or Szczecin. After customs clearance (1–3 days) the container moves by road to its destination.
And here the problem begins.
The receiving factory — a manufacturer of pipes, film or packaging — needs granulate delivered in a silo trailer that drives directly under the plant’s storage silo. A container on a flatbed cannot discharge into a silo inlet. The big-bags must be transloaded — from the container into a silo trailer. That is exactly what a transloading terminal does.
The second problem: the container arrives according to the shipping line’s schedule, not the factory’s production schedule. The factory needs a steady delivery rhythm — five silo trailers per week, every Monday and Thursday. The container may arrive on a Wednesday or Friday. A terminal buffers these mismatches.
The SMIALA solution: container to silo trailer cross-docking in 24–48 h
The container intake procedure at SMIALA:
1. Container reception — the flatbed with the container drives through the gate; truck scales record the gross weight. The operator verifies the CMR, delivery note and material specification. Every delivery receives an intake number and a warehouse card.
2. Big-bag unloading — a forklift unloads big-bags either to the designated warehouse zone or directly to the loading station (if a silo trailer is ready).
3. Silo trailer loading — the trailer parks under the gravity loading station. The operator opens the top filling hatch of the tank. A gantry crane or forklift with bale clamps raises the big-bag to approximately 3.5–4.5 m above the floor. The bottom discharge valve of the bag is opened and the granulate flows by gravity into the tank.
4. Net weighing and documentation — the trailer is weighed after loading. The transloading protocol is ready within one hour.
A standard silo trailer BT 65 (65 m³) holds 22–27 tonnes of PE/PP granulate — that is 22–27 big-bags of 1 tonne each.
Logistics route: Korea/China → port → SMIALA → factory
Chorula is located at the centre of Central Europe, on the A4 — the main transport corridor between Berlin and Kraków.
| Route | Sea transit | Distance from Chorula |
|---|---|---|
| South Korea (Busan) → Hamburg | 28–32 days | ~720 km (1 day) |
| South Korea → Gdansk | 30–35 days | ~450 km (1 day) |
| China (Shanghai) → Hamburg | 28–35 days | ~720 km (1 day) |
| China → Gdansk/Szczecin | 30–36 days | 450–550 km (1 day) |
From Chorula, a silo trailer reaches:
- Opole / Wrocław / Katowice: 1–2 h
- Warsaw: 3–4 h
- Prague / Brno: 3–4 h
- Vienna / Linz: 6–7 h
- Munich / Stuttgart / Frankfurt: 6–9 h
Why the gravity method protects granulate quality
PE and PP granulate is traded against a strict specification. The producer issues a Certificate of Analysis (CoA) stating: melt flow index (MFI), ash content, bulk density, particle size distribution. The factory expects the granulate in the silo trailer to match the CoA exactly.
Pneumatic transloading can alter those parameters in three ways:
Fractionation — in a pneumatic pipeline, heavier granules settle faster while lighter particles (dust, fines) remain airborne longer. The result in the trailer tank is a non-uniform mixture: the top of the tank contains fines, the bottom contains heavier granules. When the factory discharges this into its silo, it receives inconsistent material — different MFI, different rheology, potential processing issues.
Electrostatic charging — friction between the granulate and the pipeline walls builds up static charge on the PE/PP particles. Charged fines stick to the tank walls and do not slide out during discharge. The trailer retains several kilograms of material between loads — cross-contamination between batches, cleaning difficulties, possible customer complaints on grade changes.
Contamination from the pneumatic system — every pneumatic system contains a compressor, oil separator and filters. Even with a functioning separator, trace amounts of oil enter the air stream. For PE grades intended for food-contact packaging or drinking-water pipes, this contaminates the entire batch.
The SMIALA terminal uses gravity transloading exclusively. No pneumatic pipelines, no compressors in the material stream. The granulate arrives in the trailer tank in exactly the same condition as in the big-bag.
Documentation: CMR, weighing protocol, ISO 9001:2015
Every transloading operation at SMIALA is fully documented:
- Transloading protocol — gross and net weights, big-bag numbers, producer batch number, date and time, trailer and driver details
- CMR — issued on request for transport to Germany, Austria, the Czech Republic and other EU countries
- Warehouse card — for buffered storage: intake time, warehouse location, release date, FIFO sequence
- Goods receipt — with producer batch number for corporate clients requiring full traceability
All documents are archived for a minimum of five years. The SMIALA terminal operates under ISO 9001:2015 certification — the quality management system covers intake, transloading, warehousing and dispatch procedures.
Clients: who we serve
The SMIALA terminal has experience handling PE/PP granulates from leading producers:
- LG Chem (South Korea) — PE/PP granulates for film and engineering applications
- Borealis (Austria/Finland) — Borstar PE, Borealis PP grades
- Synthos (Poland) — rubber granulate and EPS
- Orlen (Poland) — PE granulate manufactured in Płock
Each supplier has different documentation requirements and different big-bag specifications. We know these differences — we know how to receive and transload cargo in line with each producer’s quality requirements.
