Complete Guide to Seafood Packaging Bags
Choosing the right seafood bags protects your product quality, prevents customer complaints, and ensures safe transport from your seafood counter to your customer's kitchen.
What Makes a Good Seafood Bag?
Material matters: Low-density polyethylene (LDPE) is the industry standard for seafood bags because it's flexible, puncture-resistant, and moisture-proof. Unlike paper bags that can tear when wet or mesh bags that leak, LDPE plastic bags contain liquids and prevent drips.
Thickness (gauge): Seafood bags typically range from 1.5 to 3 mil thickness. Thicker bags (2.5-3 mil) handle sharp shells and crab claws without tearing. Thinner bags (1.5 mil) work for smaller items like shrimp or scallops.
FDA compliance: All seafood packaging must meet FDA food-contact standards. Our bags are manufactured with virgin polyethylene approved for direct contact with fresh and frozen seafood.
Types of Seafood Bags We Offer
Standard seafood merchandise bags: Clear or printed LDPE bags with bottom gussets. Easy to fill, tie off, and display. Most popular for retail fish counters.
Clam bags / shellfish bags: Extra-heavy bags designed to handle sharp shells without puncturing. Perfect for live clams, mussels, oysters, and crabs.
Fish market bags: Larger bags (12"x18" or bigger) for whole fish, salmon fillets, or bulk seafood orders.
Freezer bags: Thicker gauge bags that remain flexible in freezing temperatures. Ideal for frozen seafood retail or storage.
Seafood Bag Sizes - How to Choose
- Small (8"x12"): Shrimp, scallops, small portions (1-2 lbs)
- Medium (10"x15"): Crab legs, lobster tails, fish fillets (2-5 lbs)
- Large (12"x18"): Whole fish, bulk shellfish, large orders (5-10 lbs)
- Extra-large (15"x20"+): Whole salmon, large crabs, catering quantities
How to Use Seafood Bags Properly
For fresh seafood: Place product in bag, remove excess air, and tie or seal the top with a twist tie. Keep refrigerated. Fresh seafood should reach the customer within 2 hours or remain on ice.
For frozen seafood: Ensure product is fully frozen before bagging. Remove as much air as possible to prevent freezer burn. Label with date and contents.
Odor control tip: Double-bag strong-smelling seafood (like mackerel or mussels) for extra odor protection during checkout and car transport.

Frequently Asked Questions About Seafood Bags
Are seafood bags food safe for direct contact with fresh fish?Yes. Prism Pak seafood bags are manufactured from FDA-compliant virgin polyethylene approved for direct contact with fresh and frozen seafood, so fish, shellfish, and fillets can go straight into the bag with no liner or wrap required. What size seafood bag do I need?Match the bag to the weight of the order: 8"x12" holds 1-2 lbs of shrimp, scallops, or small portions; 10"x15" holds 2-5 lbs of crab legs, lobster tails, or fish fillets; 12"x18" holds 5-10 lbs for whole fish and bulk shellfish; and 15"x20" or larger handles whole salmon, large crabs, and catering quantities. Will a seafood bag keep fish smell out of my car?Bags of 2 mil thickness and heavier significantly reduce odor transfer during checkout and transport. For strong-smelling seafood such as mackerel or mussels, double-bagging adds another layer of odor and leak protection. Can you freeze seafood in these bags?Yes. LDPE seafood bags stay flexible at freezer temperatures instead of cracking. Freeze the product first, press out as much air as possible to prevent freezer burn, and label with the date. For storage beyond about three months, vacuum-seal pouches hold quality better. What is the difference between a seafood bag and a regular plastic bag?Seafood bags run 1.5 to 3 mil thick versus roughly 0.7 mil for a standard grocery bag, are made from heavier-duty LDPE, and are FDA-compliant for food contact. That extra gauge is what resists punctures from shells, bones, and crab claws and keeps moisture from leaking through. How many seafood bags come in a case?Most seafood bags are packed 500 to 1,000 bags per case depending on the size, and there is no minimum order beyond the case. Exact case counts are listed on each individual product page. Related Seafood Packaging Products
