Choosing corrugated seafood packaging by ply count alone is a bit like choosing a truck by paint color. The visible feature is there, but it does not tell you enough about how the vehicle will perform. In seafood, the same rule applies to packaging: if you start with “three-ply or five-ply?” before you understand the route and the failure risk, you are already skipping the important part.
In e-commerce, packaging impacts shipment protection, shipping cost, packing time and the amount of waste your customer has to deal with.
