The BSC PREFERRED T4448INNER is an HSC-style inner corrugated carton manufactured from 200/ECT-32 kraft corrugated board. It is designed to function as the inner component of a two-piece adjustable carton set, pairing with the T4448OUTER to create a telescoping box capable of accommodating varying load heights. The full overlap (FOL) bottom construction distributes weight evenly and resists blowouts under load. Sold in packs of 25, this carton is a practical option for shipping departments, warehouse operations, and fulfillment centers that need flexible, heavy-duty corrugated packaging solutions. Licensed trade and logistics professionals handling bulk or irregular freight will find this format straightforward to integrate into existing pack-out workflows.
This inner carton is suited for general freight, bulk cargo, and industrial shipping applications where adjustable carton height is required. It can be used as a standalone box or combined with the T4448OUTER companion piece to form a complete two-piece adjustable set. One inner carton and one outer carton are required to complete a set; each piece is sold separately. Typical applications include warehousing, distribution, and e-commerce fulfillment operations that ship variable-height products.
Designed to pair with the T4448OUTER companion carton to form a complete two-piece adjustable HSC-style carton set. One T4448INNER and one T4448OUTER are required per set; both pieces are sold separately.
No tools are required for assembly. When combining with the T4448OUTER, ensure the inner carton slides freely within the outer before loading to confirm proper telescoping fit. Verify the FOL bottom flaps are fully overlapped and seated before placing product inside. Follow applicable packaging and freight guidelines for weight limits and stacking requirements.
