When a procurement team requires precise dimensions, weight capacity, and packaging structure before soliciting pricing, the typical wholesale inner pack for a 7.5KG frozen seafood block is a 481×253×60mm waxed block liner.
For a Russian or CIS seafood importer arranging a frozen fish block export, packaging begins with a fundamental inquiry: does the liner contain the block, withstand cold storage, and align with pallet logistics? The standard wholesale waxed block liner for this application has dimensions of 481×253×60mm and supports a 7.5KG frozen fish block. It is constructed from 337G kraft or white coated paper, with food-grade PE film applied to both interior and exterior as the baseline configuration. Wax coating remains an optional enhancement. Once these parameters are established, buyers can evaluate different suppliers and submit a quote request using concrete figures rather than ambiguous samples.
481x253x60mm Block Liner Dimensions and 7.5KG Load for Frozen Seafood Exports
This 481×253×60mm block liner serves as a dedicated paper container for a 7.5KG frozen fish block. Its length and width correspond to the block mould, while the 60mm depth ensures a compact profile yet provides adequate board for stacking. During a seafood export batch, personnel fill and seal the liners, then place them into master cartons for cold storage and pallet loading. FAO cold storage guidelines regard block packaging as integral to the freezing and storage process, given that the packaging safeguards the product against moisture loss, physical damage, and temperature fluctuations. A liner that precisely fits the block minimizes unnecessary void space and facilitates easier master carton handling. Board selection carries equal importance to dimensions. Supplier BEF GROUP utilizes 337G kraft or white coated paper for this 7.5KG waxed block liner, designated model No. BEF-S006. Moisture content is maintained below 14%, aiding the board's stiffness retention in cold, damp environments. The standard configuration includes food-grade PE film on both inner and outer surfaces. This film restricts moisture transfer between the fish block and the paper, preventing the board from softening during freezing, storage, and thawing cycles. Optional wax coating offers additional surface moisture resistance in scenarios where condensation is prevalent when moving in and out of cold rooms. Furthermore, the liner employs a low-temperature adhesive nominally rated for -40℃, enabling assembly under frozen seafood export conditions. Note that the -40℃ rating is a nominal design parameter; therefore verify your specific temperature requirements when placing an order. For export destinations, food-contact paper and coating selections fall under regulations such as EU 1935/2004, so purchasers should request the applicable material description for their target market.
Euro Type and Fold Type Waxed Block Liners for Wholesale Shipments
Large-volume frozen seafood orders typically require a box style compatible with both the packing line and the warehouse. The 7.5KG block liner is available in two structural variants: Euro type lid and bottom, and fold type. Although both share identical core dimensions and load capacity, they alter the way your crew assembles, fills, and stores the liner prior to packing the fish block. This decision impacts labor requirements, storage footprint, and pallet presentation. Selecting the appropriate construction depends on your freezing technique, packing pace, and container loading strategy.
1. Euro Type Lid and Bottom Suits Stacked Block Freezing and Pallet Loading
The Euro type lid and bottom design provides a distinct lid and base for the liner. This configuration maintains its form when blocks are stacked for freezing and subsequently transferred onto pallets. On a high-volume seafood export line, the lid and base can be pre-assembled before filling, enabling workers to maintain a consistent packing tempo. The pre-formed shape further aids stacking when master cartons are placed several layers high in cold storage. For shipments that undergo repeated pallet handling, the Euro type is often simpler to standardize across a wholesale order due to its clean, square block profile and even stacking capability. The downside is increased storage space prior to use, as lids and bases occupy more room than a flat folded liner.
2. Fold Type Block Liners Reduce Storage Space Before Seafood Packing
Fold type block liners are delivered flat and are shaped at the packing station. This reduces warehouse space requirements before the seafood packing run, a critical factor when cold storage capacity is limited or when a large wholesale batch arrives in a single shipment. The fold type supports the same 7.5KG block and incorporates the same PE film and optional wax protection. It is suitable for processors aiming to keep packaging inventory compact and assemble liners on demand. The choice ultimately hinges on your line: if labor is available at the packing table and space is constrained, the fold type is a pragmatic option. If a pre-formed box that retains its shape during stacking is needed, the Euro type generally offers a better solution.
Matching MOQ, Pallet Loading, and Lead Time to a Wholesale Order
The minimum order quantity for this 7.5KG block liner is 1000 pieces per design. This MOQ applies individually to each design; therefore, if two print versions are needed, two separate production runs are required. For a frozen seafood export batch, 1000 pieces represents a practical starting volume for a regular shipment, providing sufficient liners to test the packing line before committing to a larger repeat order. Typically, a waxed block liner manufacturer will base their quotation on the same core parameters: box dimensions, board weight, PE film, optional wax, print specifications, and quantity. A wax paper liner manufacturer might quote the same dimensions with different board stocks, so confirm that 337G kraft or white coated paper is specified. If only PE film is required without wax, the liner still functions as a moisture-resistant food container. Wax adds extra surface moisture resistance beyond the PE film. Lead time generally ranges from 7 to 15 working days after order details and artwork are confirmed. Plain liners are produced faster; custom printed liners require additional time for plate or print setup. Pallet loading also varies with quantity, print complexity, and temperature requirements. The liners are packed in poly bags, then cased and shipped on pallets. This packing method protects the board before use and improves container loading predictability. When requesting a wholesale quote, provide the supplier with the fill weight, target temperature, box type, print artwork, and order quantity. A paper food box manufacturer can then determine pallet configuration, lead time, and the most efficient production approach. Suppliers such as BEF GROUP derive their quotes from these specifics rather than a single blanket price, because print, wax, and temperature demands alter the material and packing plan.
Conclusion
The 481×253×60mm, 7.5KG waxed block liner becomes a standard frozen seafood export component once you know the key specifications: 337G kraft or white coated paper, food-grade PE film on both interior and exterior as the baseline, optional wax, and a selection between Euro type and fold type construction. Align the box type with your packing line, verify the MOQ of 1000 pieces per design, and schedule around a lead time of 7 to 15 working days. When submitting a wholesale inquiry, include the fill weight, target temperature, box type, print artwork, and quantity. Suppliers like BEF GROUP can review those details and provide a practical specification quote tailored to your frozen seafood export batch.
FAQ
Q：What is the purpose of a 481x253x60mm wholesale waxed block liner in frozen seafood exports?
A：It functions as a shallow, rigid paper liner designed for a 7.5KG frozen fish block. Exporters fill it with the block, seal it, and then stack the liners into master cartons for cold storage, pallet loading, and container transport. The 481×253×60mm dimensions keep the block compact, while the 337G paper and food-grade PE film help the liner maintain its shape during freezing and handling. Optional wax provides additional surface moisture resistance in environments where condensation is a concern.
Q：Is wax coating included by default on each 7.5KG block liner, or can I order with PE film alone?
A：Food-grade PE film on both interior and exterior is the standard base configuration. Wax coating is optional. If your cold-chain path experiences significant condensation or frequent temperature fluctuations, wax can enhance surface moisture resistance. If PE film alone suffices, you can order the liner without wax. Both options share the same 481×253×60mm dimensions and 7.5KG load capacity, so the decision depends on your storage and handling conditions.
Q：Which details should I provide when requesting a wholesale quote for frozen seafood block liners?
A：Provide the block size and fill weight, target temperature, preferred box construction, print artwork, and order quantity. For this liner, the standard dimensions are 481×253×60mm with a 7.5KG load, and the MOQ is 1000 pieces per design. Indicate whether you require PE film only or PE film plus optional wax. These specifics enable the supplier to confirm pallet loading, lead time, and an accurate wholesale price for your frozen seafood export batch.
