Recommendations Plastic and metal containers have advantages over plastic bags for shipping and distributing fresh fish fillets. They are sturdier than poly bags and do not leak if properly sealed. Plastic and metal containers are also reusable after being cleaned and sanitized, as long as there are no cracks or punctures in the container. Shallow plastic and metal containers allow fillets to cool quickly and little shelf life is lost during the chilling process. Waxed cardboard have the disadvantage of insulating the fish fillets from the surrounding ice and causing the fillets to cool slowly.
Poly bags become almost round when filled and iced.
Ten and 20 lb. This additional thickness results in slow chilling of the fillets. Plastic and metal containers are available in a range of lengths, widths, and depths. Because cooling rates are proportional to container depth, containers for fish fillets should be relatively shallow. A maximum depth of 3 inches is recommended for containers used for fresh fish fillets.
