Start with carton volume and exposure
Packet size should not be selected only by habit. Export buyers should look at carton volume, air space, packaging barrier, sea or air route, and how long the product may sit in warehouse storage.
- Use smaller sachets for compact retail cartons and inner packs.
- Increase dosage for humid routes, long storage, and weak carton barriers.
- Use container strips or bulk formats when the moisture risk is outside the product carton.
Match the format to the risk
A 0.5g sachet and a 100g sachet solve different problems. The correct format depends on whether the buyer is protecting a single pack, master carton, pallet, or shipping container.
- 0.5g to 10g: retail packs, electronics, medicines, samples, and small cartons.
- 25g to 500g: master cartons, drums, crates, machinery parts, and storage bins.
- 1kg to 5kg and strips: bulk cargo, pallets, container loading, and long-haul export shipments.
Validate before high-volume orders
For serious procurement, the best path is to test samples against the buyer's packaging, route, destination humidity, and expected shelf time before locking MOQ.
- Request product samples in the closest planned sachet material and size.
- Ask for SDS and COA before purchase approval.
- Share destination country, carton size, quantity, and Incoterms with the supplier.
