Introduction: A 481×253×60mm waxed block liner is the standard wholesale inner pack for a 7.5KG frozen seafood block when the buying team needs a defined size, load, and box construction before requesting a quote.
When a Russian or CIS seafood importer plans a frozen fish block shipment, packaging starts with one practical question: will the liner hold the block, survive cold storage, and fit the pallet plan? The standard wholesale waxed block liner for this job measures 481×253×60mm and carries a 7.5KG frozen fish block. It uses 337G kraft or white coated paper, with food-grade PE film inside and outside as standard. Wax coating is optional. Once these specifications are clear, you can compare suppliers and request a quote with defined numbers instead of vague samples.
A 481×253×60mm block liner is a purpose-built paper box for a 7.5KG frozen fish block. The length and width match the block mould; the 60mm height keeps the block compact while leaving enough board for stacking. In a seafood export batch, workers fill and close the liners, stack them into master cartons, and move them through cold storage and pallet loading. FAO cold storage guidance treats block packaging as part of the freezing and storage chain because the package protects the product from dehydration, handling damage, and temperature swings. A liner that fits the block correctly reduces wasted space and makes the master carton easier to handle. Board choice matters as much as dimensions. BEF GROUP uses 337G kraft or white coated paper for this 7.5KG waxed block liner, model No. BEF-S006. Moisture content stays under 14%, which helps the board keep its stiffness in cold, humid conditions. Food-grade PE film inside and outside is the base configuration. That film limits moisture movement between the fish block and the paper, so the board resists softening during freezing, storage, and thawing. Optional wax adds another layer of surface moisture resistance when condensation is heavy in and out of cold rooms. The liner also uses a low-temperature adhesive nominally rated for -40℃, which supports assembly in frozen seafood export conditions. The -40℃ figure is a nominal design condition, so confirm your exact temperature profile when ordering. For export markets, food-contact paper and coating choices sit inside frameworks such as EU 1935/2004, so buyers should request the material description that applies to their destination.
Wholesale frozen seafood orders usually need one box style that fits the packing line and one that fits the warehouse. The 7.5KG block liner comes in two constructions: Euro type lid and bottom, and fold type. Both use the same core size and load, but they change how your team assembles, fills, and stores the liner before the fish block is packed. The choice affects labour, storage space, and pallet presentation. The right construction matches your freezing method, packing speed, and container loading plan.
Euro type lid and bottom gives the liner a separate lid and base. That construction holds its shape when blocks are stacked for freezing and later moved onto pallets. On a busy seafood export line, the lid and bottom can be assembled ahead of filling, so workers can keep a steady packing rhythm. The pre-formed shape also helps when master cartons are stacked several layers high in cold storage. If your shipment moves through repeated pallet handling, Euro type is often easier to standardise across a wholesale order because it presents a clean, square block profile and supports even stacking. The trade-off is storage space before use, since lids and bases take up more room than a flat folded liner.
Fold type block liners arrive flat and are folded into shape at the packing station. That saves warehouse space before the seafood packing run, which matters when cold storage is tight or when you receive a large wholesale batch in one delivery. The fold type still carries the same 7.5KG block and uses the same PE film and optional wax protection. It suits processors who want to keep packaging inventory compact and assemble liners as needed. The decision comes down to your line: if labour is available at the packing table and space is limited, fold type is practical. If you need a pre-formed box that holds shape during stacking, Euro type is usually the better fit.
The standard order quantity for this 7.5KG block liner is 1000 pcs per design. That MOQ applies to each design, so if you need two print versions, plan for two production runs. For a frozen seafood export batch, 1000 pcs is a workable starting volume for a regular shipment, and it gives you enough liners to test the packing line before committing to a larger repeat order. A waxed block liner manufacturer will usually quote from the same core facts: box size, board weight, PE film, optional wax, print, and quantity. A wax paper liner manufacturer may quote the same size with different board stocks, so confirm 337G kraft or white coated paper in the specification. If you only need PE film without wax, the liner still works as a moisture-resistant food box. Wax adds surface moisture resistance on top of the PE film. Lead time typically runs 7-15 working days after order details and artwork are confirmed. Plain liners move faster; custom printed liners need more time for plate or print setup. Pallet loading also changes with quantity, print, and temperature requirement. The liners are packed in poly bags, then cased and shipped on pallets. That packing method protects the board before use and makes container loading more predictable. When you request a wholesale quote, give the supplier the fill weight, target temperature, box type, print artwork, and order quantity. A paper food box manufacturer can then confirm pallet configuration, lead time, and the most efficient production route. BEF GROUP quotes from these details instead of a single blanket price, because print, wax, and temperature needs change the material and packing plan.
The 481×253×60mm, 7.5KG waxed block liner is a standard frozen seafood export item once you know what to look for: 337G kraft or white coated paper, food-grade PE film inside and outside as standard, optional wax, and a choice of Euro type or fold type construction. Match the box type to your packing line, confirm the MOQ of 1000 pcs per design, and plan around a 7-15 working day lead time. Before sending a wholesale inquiry, include the fill weight, target temperature, box type, print artwork, and quantity. BEF GROUP can review those details and return a practical specification quote for your frozen seafood export batch.
A：It is a shallow, rigid paper liner sized for a 7.5KG frozen fish block. Exporters fill it with the block, close it, and stack the liners into master cartons for cold storage, pallet loading, and container shipment. The 481×253×60mm size keeps the block compact, while 337G paper and food-grade PE film help the liner hold shape through freezing and handling. Optional wax adds surface moisture resistance when condensation is a concern.
A：Food-grade PE film inside and outside is the standard base configuration. Wax coating is optional. If your cold-chain route has high condensation or repeated temperature swings, wax can add surface moisture resistance. If you only need the PE film, you can order the liner without wax. Both versions use the same 481×253×60mm size and 7.5KG load, so the choice depends on your storage and handling conditions.
A：Send the block size and fill weight, target temperature, preferred box construction, print artwork, and order quantity. For this liner, the standard size is 481×253×60mm with a 7.5KG load, and the MOQ is 1000 pcs per design. Include whether you need PE film only or PE film plus optional wax. Those details let the supplier confirm pallet loading, lead time, and an accurate wholesale price for your frozen seafood export batch.
