关键要点
- Specify bag type, weight, liner, pallet configuration and marking explicitly.
- Marking must carry lot identity for traceability to survive.
- Packaging choice must match the route's climate and handling profile.
Choosing the format
Bagged, big bags or bulk each imply different handling equipment, storage density and labour. Choose the format your warehouse actually handles efficiently rather than the one that quotes cheapest per tonne.
Protection level
Woven polypropylene alone offers limited moisture protection; laminated or lined bags perform better on humid routes. Sensitive materials may require sealed liners with the moisture barrier defined in the specification.
Marking and identification
Product name, producer, lot number, production date, net weight, storage instructions and any regulatory marking. Lot number on the packaging is what makes traceability work when documents and material are separated.
需要核查的内容
- Packaging type, weight and liner specified contractually
- Marking content and language confirmed against import requirements
- Pallet configuration matched to warehouse and container dimensions
需管理的风险
- Moisture ingress through inadequate packaging on humid routes
- Bag breakage and losses during multiple handling stages
- Marking that does not meet destination regulatory requirements
常见错误
- Accepting the supplier's standard packaging without review
- Omitting lot number from the packaging marking
- Ignoring pallet dimensions and losing container capacity
常见问题
Are big bags better than small bags?
They reduce handling labour and are efficient where mechanical handling exists. Where handling is manual or storage is fragmented, smaller bags are often more practical.
What marking is mandatory?
It depends on the destination's feed labelling regulation. Confirm the requirement before production, since re-marking at destination is expensive and sometimes not permitted.
