Kraken Stackers automate the orderly stacking of products for transfer to cartoners, case packers, or palletizing systems. Designed as case stacker and stacking machine solutions for high-speed production, they maintain product alignment and orientation while preparing consistent stacks for the next stage of packaging.
A product stacking system has to do more than place one product on top of another. The system needs to account for how products arrive, the orientation required within the stack, product stability, line speed, and how the completed stack must be presented to the next packaging process.
Manual stacking can slow production, create ergonomic concerns from repetitive motion or heavy lifting, increase labor costs and safety risks, and contribute to product damage. An automated stacking machine helps create consistent stacks, reduce manual handling, and support more reliable downstream flow.
An automatic package stacker also needs to account for upstream product flow and the condition required by the downstream process. Product size, shape, weight, stability, and fragility can influence how products should be collected and stacked. The stacking method should be engineered around the product and required stack configuration rather than applying the same handling approach to every package.

A product stacking system is an automated product-handling solution designed to organize products or cases into consistent stacks for downstream packaging or material-handling processes.
In Kraken applications, stacking is used to prepare product for equipment such as cartoners, case packers, or palletizing systems while maintaining controlled alignment and orientation. The goal is to create a repeatable stack configuration while reducing manual handling and supporting smoother downstream flow.
An automatic package stacker receives product from the upstream line, organizes it into the required stack configuration, and presents the completed stack for the next process.
The exact stacking method is application-specific. Product characteristics, incoming product flow, line speed, orientation requirements, lane configuration, and the way the downstream machine needs to receive the stack all influence how the system is engineered.
The required stack configuration should be based primarily on the product and the needs of the downstream process.
Important considerations can include product size and shape, orientation, stability, fragility, incoming lane configuration, available floor space, production rate, and how the completed stack will be transferred to a cartoner, case packer, palletizer, or other downstream equipment. Kraken engineers the stacking function as part of the overall packaging flow rather than treating the stack pattern as an isolated decision.
Product size, shape, weight, stability, fragility, orientation, and behavior during transfer can all affect stacking-system design.
A rigid case may behave differently from a flexible or irregular-shaped package, and heavier or fragile products can require different handling considerations. Kraken evaluates the product together with line speed, lane configuration, downstream requirements, and surrounding equipment before determining the appropriate stacking approach.
Maintaining alignment and stack stability requires the product to remain controlled as it enters the stacking process, is organized into the stack, and is transferred downstream.
The appropriate handling method depends on the product and the required stack configuration. Product orientation, shape, size, stability, incoming flow, and downstream presentation requirements all influence how the system should support and transfer the stack. Kraken does not apply one standard stacking mechanism to every application.
Yes. Kraken stacking systems can be engineered for both single-lane and multi-lane applications.
The appropriate configuration depends on how products arrive from upstream equipment and how the finished stacks need to be presented downstream. Lane count, product spacing, production rate, product characteristics, and available floor space are considered as part of the overall flow-management solution.
Stacking depends on receiving product in a way that allows the required stack to be formed consistently. Changes in upstream rate, product spacing, or lane availability can affect when products should be collected and when a completed stack can be released.
The stacking strategy should therefore be engineered in context with upstream product variability, line-speed requirements, downstream demand, and recovery conditions. This helps keep the stacking process coordinated with the rest of the packaging line rather than allowing it to become a bottleneck.
Yes. A stacking system can be coordinated with other flow-management functions such as Smart Infeed, Accumulation, or Divert to control how product reaches the stacking process.
Depending on the application, these systems can help manage product spacing, upstream variability, temporary buffering, routing, and the timing of product entering the stacker. The exact configuration depends on the product, line rate, lane arrangement, available floor space, and downstream requirements.
Stacking can be engineered to prepare products or cases in the configuration required by downstream Case Packing or Case Routing & Palletizing equipment.
The stacking system needs to consider how the completed stack will be transferred, its orientation and stability, the timing required by the downstream machine, and how the surrounding product-handling equipment and controls operate. Kraken can coordinate the stacking function with case packing, product handling, and palletizing equipment as part of the broader packaging line.
The completed stack should be presented in the orientation and configuration required by the downstream machine.
That can include maintaining consistent alignment, keeping the stack controlled during transfer, and coordinating the release of the stack with the next process. The specific requirements depend on the product and the downstream equipment, which is why Kraken evaluates stacking together with the surrounding cartoning, case packing, or palletizing process.
Product stacking organizes products or cases into controlled stacks as part of the packaging flow. Those stacks may then be transferred to another packaging process, including case packing or palletizing.
Palletizing is the downstream process of arranging cases or other loads onto a pallet. A stacking system can support or feed a palletizing operation, but stacking and palletizing are not necessarily the same function.
Yes. Kraken can engineer a packaging line stacker around existing upstream and downstream equipment as well as new machinery.
Important considerations can include available floor space, existing transfer points, product characteristics, lane configuration, production rate, upstream product flow, downstream equipment requirements, controls integration, and recovery conditions. The goal is to make the stacking function operate as part of the coordinated packaging system rather than as a standalone machine.
Kraken can help engineer a packaging line stacker around your product, stack requirements, surrounding equipment, and production goals.
Kraken does more than supply equipment—we coordinate the entire solution so your line operates as one seamless system. We integrate new and existing machines, design transfer and conveyor elements, align product handling, and synchronize controls from upstream to downstream. The goal isn’t just installation—it’s reliable, high-performance operation.
