Custom bags and liners for fresh, iced, and frozen seafood, specified for moisture, shells or fins, filled weight, container fit, cold handling, and customer validation.
Seafood exposes weak seals and underspecified film quickly. Fresh fillets, shellfish, frozen blocks, and iced shipments impose different puncture, liquid, and temperature demands. M Plastics can manufacture FDA-grade LDPE options, but package performance must be established with the actual seafood and shipping system.
Seafood quickly exposes a weak seal or underspecified film. M Plastics has addressed this work by focusing first on liquid containment, puncture points, ice, and frozen handling. Because extrusion and converting happen at our Los Angeles facility, our team can tune mil thickness, bag fit, and seal construction around the product instead of treating fresh fish, shellfish, and frozen portions as the same application.
Provide filled weight, product shape, shell or fin exposure, fresh or frozen temperature, ice use, liquid volume, shipping container, and closure method. We use those conditions to recommend mil thickness, seal style, bag dimensions, and liner fit.

View Product →mil thickness, resin blend, and dimensions work together. A thicker bag can still fail if it is tight over a shell or caught in a case flap. Food-contact material documentation should be requested with the intended conditions of use.
Manual loading requires enough mouth opening and length for safe closure. Equipment-fed applications require bag presentation, wicket or roll details, seal settings, and wet-line trials.
Evaluate filled bags with product, ice, minimum temperature, closure, container, stacking, and expected drops. “Leak-proof” should be treated as a construction goal to validate, not a universal guarantee.
A material declaration or FDA-grade resin does not approve a finished package for every product or process. The customer remains responsible for application-specific regulatory review and validation.
Practical answers from a manufacturer. Final specifications are confirmed for your product, equipment, and use conditions.
Correct bag fit, adequate mil thickness, and the right bottom-seal construction are critical. We recommend validating the bag with the actual product, ice, and distribution conditions.
Yes. Heavier-mil thickness LDPE can improve puncture resistance for shells and frozen edges, subject to application testing.
Yes. We manufacture custom box and container liners in food-contact materials and sizes matched to the container.
Review a production-representative sample with the actual product, packing method, closure, storage, and distribution conditions. Approval criteria should be documented before the full run.
Provide filled weight, product shape, shell or fin exposure, fresh or frozen temperature, ice use, liquid volume, shipping container, and closure method. We use those conditions to recommend mil thickness, seal style, bag dimensions, and liner fit.
Send the product, dimensions, filled weight, temperature, packing method, equipment details, closure, print, documentation needs, and expected handling. We will review a manufacturable specification for your seafood application.
