CROSS-REFERENCE TO RELATED APPLICATION The present application claims priority to U.S. Provisional Patent Application No. 63/714,935 entitled “METHOD AND SYSTEM FOR FORMING A PACKAGE” filed Nov. 1, 2024 and to U.S. Provisional Patent Application No. 63/715,028 entitled “METHOD AND SYSTEM FOR FORMING A PACKAGE” also filed Nov. 1, 2024. INCORPORATION BY REFERENCE The disclosure of U.S. Provisional Patent Application No. 63/714,935 entitled “METHOD AND SYSTEM FOR FORMING A PACKAGE” filed Nov. 1, 2024, is hereby incorporated by reference for all purposes as if presented herein in its entirety. Additionally, the disclosure of U.S. Provisional Patent Application No. 63/715,028 entitled “METHOD AND SYSTEM FOR FORMING A PACKAGE” filed Nov. 1, 2024, is hereby incorporated by reference for all purposes as if presented herein in its entirety. BACKGROUND Container packaging systems may encounter a variety of operational challenges that impact efficiency and reliability in commercial applications. Instability and misalignment of containers during automated transport can create downstream processing problems, while floor space requirements for conventional equipment limit facility layout options and reduce overall manufacturing flexibility. Existing packaging systems may struggle to maintain consistent container positioning, often resulting in separation of individual containers from their groups and disruptions to automated processing sequences. Conventional packaging methods also frequently fail to provide sufficient protection against impact damage during storage and shipping, leading to crushing, surface damage, and the need for manual intervention. High mechanical forces during folding and dynamic assembly operations may further reduce efficiency, accelerate equipment wear, and increase maintenance demands. These operational shortcomings may drive increased labor requirements due to frequent manual adjustments or system stoppages. Inefficiencies in space utilization and transportation often result in higher storage and shipping expenses, expanded facility requirements, and increased supply chain costs. Frequent system downtime and component failures may interrupt production schedules, reduce throughput, and compound operational expenses, while unreliable packaging operations may also lead to product damage-related losses and additional quality assurance challenges. As a result, conventional packaging system limitations may create broader negative impacts throughout the industry. These impacts may include increased environmental waste, inefficient warehouse utilization, production and distribution delays, and difficulties meeting modern supply chain demands for speed, flexibility, and compliance. Emerging requirements for sustainability, regulatory compliance, real-time operational visibility, and package customization continue to widen the performance gap between current market needs and the capabilities of existing packaging machinery.
