Comparison of the Different Types of Case Tapers

In today’s fast-paced packaging environment, reliable and efficient case sealing is essential. Manual taping not only slows down production but also increases the risk of inconsistent seals and higher material costs. Eastey’s range of case tapers offers a suite of solutions designed to meet the unique demands of high-volume operations, each tailored for specific case sizes, weights, and production needs. In this post, we compare the different types of case tapers—BB, SB, TB, TB/SB, Random, and Auto—to help you choose the best fit for your operation.

Overview of Eastey Case Taper Solutions

Eastey’s product lineup is designed with durability, versatility, and ease of use in mind. Constructed from 12-gauge steel and available in stainless steel options for washdown conditions, these machines are built to withstand rugged industrial environments. They feature plug-and-go operation, quick-change tape cartridges, and adjustable components to accommodate a wide range of box sizes—from narrow, low-profile boxes to oversized, heavy-duty cases.

The BB Series – Bottom Belt Case Tapers

The BB series, including the BB-2 and its stainless steel counterpart BB-2/SS, focuses on high-volume sealing with efficiency and reliability.

  • BB-2: Engineered for large-run case sealing, this model boasts self-centering side rails and a rugged bottom belt drive, making it ideal for a variety of case sizes. Its design minimizes downtime and maintenance, providing a fast alternative to hand taping.
  • BB-2/SS: Featuring 12-gauge stainless steel construction, this variant is perfect for washdown environments while delivering the same robust performance as the standard BB-2.

The SB Series – Side Belt Case Tapers

Eastey’s SB series is tailored for sealing boxes with side belt systems, perfect for light or heavy, narrow, or small boxes.

  • SB-2EX & SB-2EX-SS: Both models offer automatic side rail and tape head adjustments with interchangeable, easy-thread tapeheads. The stainless steel version (SB-2EX-SS) is designed for harsh, corrosive environments.
  • SB-2EXN: This model is designed for compact operations, featuring extended side rails and flap closing bars. It pairs seamlessly with the EX-CF Case Former to create a one-person case forming, packing, and sealing station.
  • SB-2HD: Built for extremely small or low-profile boxes, the SB-2HD can handle cases as narrow as 4 inches wide and as low as 2 inches tall—ideal when other tapers fall short.
  • Easy Packer: With features like an anvil packing station and flap closing bars, the Easy Packer simplifies manual packing and sealing, making case changes fast and efficient.

The TB Series – Top Belt & Bottom Belt Case Tapers

For operators handling tall, narrow, or heavier cases (up to 85 lbs), the TB-2 model is a strong contender.

  • TB-2: This system employs a dual mast design with twin lead screws to ensure tape head stability, along with top compression rollers and industrial-strength belts. It is specifically engineered for tall and heavy cases, offering consistent sealing without the need for compressed air.

The TB/SB Combination – Dual-Function Case Taper

The SB/TB-2 case taper marries the benefits of both side and top belt systems, delivering a versatile solution for oversized or unstable cases.

  • SB/TB-2: Featuring four drive belts working in unison and a dual mast with twin lead screws, this model provides exceptional tape head stability and precise centering of each case. It is particularly effective for overfilled or over-sized cases, ensuring a strong, consistent seal.

The Random Case Taper

When your operation handles a variety of box sizes without a standard dimension, the SB-2EX Random is designed to adapt on the fly.

  • SB-2EX Random: This model adjusts automatically to different box dimensions using sensor-based side rail and tape head adjustments. Its memory function prevents unnecessary full travel of the tape head, reducing wear and ensuring efficient, reliable sealing for void-fill cases where the packaged product does not support the box structure.

The Auto Series – Automatic Case Tapers

For maximum throughput and minimal manual intervention, the SB-2EX Auto provides full automation.

  • SB-2EX Auto: Capable of sealing up to 20 cases per minute, this machine automatically closes all four top flaps and applies tape to both the top and bottom of each case. It features an adjustable plow system, rear kicker, photoeye-controlled drop conveyor, and top squeezing rollers for accurate flap compression. Ideal for operations that require seamless integration with powered conveyors, this model delivers both speed and consistency.
