We have explored some light weight water proof boxes to house aquaculture:
Abalone
Mollusc
Crabs
Lobster
Excellent one-way packaging for live produce such as Abalone and Lobster. High volume water flow through box keeps produce in peak condition. Fits snugly into outer boxes for export. Elimates necessity to repack.
Because of water proof and stable quality under frozen , corrugated plastic boxes are widely used for different sea food products.
