Abstract
Description
A DUNNAGE FOR METAL CARGOTECHNICAL FIELD
[0001] The present disclosure, in general relates to the technical field of stowage in the shipping industry. In particular, it pertains to a simple, compact, and efficient dunnage for a metal cargo.BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In logistics industry, the transportation of heavy cargo presents significant challenges, particularly concerning the securement of goods within containers or enclosed spaces. Conventionally, materials such as wood, timber, or plastic have been utilized as dunnage for packing purposes. However, these materials exhibit limitations that compromise their effectiveness, cost-efficiency, and environmental sustainability. The usage of wood or timber materials as dunnage, while historically prevalent due to their abundance and ease of use, contributes to deforestation and poses a serious threat to the environment. Additionally, the weight and bulkiness of wooden dunnage increase transportation costs and limit cargo capacity within containers, impacting the overall efficiency of logistics operations.
[0004] In case when plastic is used as dunnage. The plastic although lighter in weight compared to wood, presents its own set of challenges. The plastic dunnage is non- biodegradable, leading to significant environmental pollution and ecological damage, and also lacks the necessary strength and durability to securely hold heavy cargo in place during transit. Moreover, disposing of plastic dunnage after use adds to the burden of waste management and exacerbates environmental concerns.
[0005] The present dunnage material used is foam material, another common choice for logic industries besides the above materials, which suffers from similar drawbacks as plastic in terms of environmental impact and inadequacy in securing heavy cargo effectively.
[0006] Given the pressing need for sustainable solutions in the logistics sector, there is a demand for dunnage materials that address these shortcomings. The above problem can be solved when a dunnage material combines biodegradability with enhanced strength and loadbearing capabilities, ensuring the securement of heavy cargo while minimizing environmentalharm and reducing logistical costs. The development of a dunnage material that is lighter in weight, cost-effective, biodegradable, and capable of withstanding the rigors of heavy cargo during transport, may be needed for the field of logistics and supply chain management.
[0007] There is, therefore, a requirement in the art to overcome the above-mentioned problems by providing a simple, compact, efficient, and dunnage for a metal cargo.SUMMARY
