Packaging specifications for bagged plastic pellets in chemical enterprises (such as PP, PE, ABS, etc.) are usually determined based on material properties, transportation requirements and industry practices. The common specifications are as follows:
1. Standard Packaging Specifications
무게
- Small bags: 10kg, 15kg, 20kg, mostly used for samples or small‑batch orders.
- Regular bags: 25kg, the most common international standard.
- Bulk bags: 500kg, 800kg, 1000kg, using jumbo / FIBC bags for large‑scale transportation.
Packaging Materials
- Outer layer: PE woven bags (moisture‑proof and tear‑resistant) or kraft paper composite bags (for eco‑friendly requirements).
- Inner layer: transparent PE inner bag (sealed and moisture‑proof; vacuum or nitrogen filling is used for some high‑grade materials).
Dimensions
- 25kg bag: approx. 90cm × 50cm, convenient for manual handling.
- Jumbo bag: 90cm × 90cm × 100cm (capacity approx. 1–1.5 cubic meters).
2. Custom Special Specifications
Industry Differences
- Food / medical‑grade plastics: aseptic packaging with QS or FDA certification marks.
- Engineering plastics (such as PC, PA): aluminum foil bags or anti‑static packaging.
Regional Preferences
- Europe: mostly 25kg per bag.
- Some Asian regions (e.g. India): 25kg or 50kg.
- North America: some manufacturers use 50 lbs (approx. 22.7kg) packages.
3. Labeling Information
Each outer bag is generally labeled with:
- Material name (e.g. LDPE, HIPS) and grade;
- Production batch number, date and shelf life (for materials sensitive to storage time);
- Net weight, manufacturer name and contact information;
- Safety signs (keep dry, keep away from fire, this side up, etc.).
4. Notes
- Moisture resistance: some plastics (e.g. PET, PA) require strict moisture protection with desiccants inside.
- Environmental trend: more enterprises are switching to recyclable / biodegradable packaging bags such as bio‑based PE bags.
It is recommended to confirm packaging details with your supplier according to the specific material, as specifications may vary among manufacturers.
