What’s the Best Case Packing System for Your Production Line?

When it comes to automating the end of your production line, case packing plays a crucial role. The right system helps you reduce labor, speed up throughput, and protect your product for shipping and retail display. But with so many options, case erectors, loaders, sealers, and wraparound packers, how do you know which is right for your needs?


Here’s how to choose the best case packing system based on your products, space, and production goals.



1. Start with Your Case Type: RSC vs. Wraparound

RSC (Regular Slotted Container) is the most common case format in U.S. packaging. It’s ideal for products that need stacking, shipping, or palletizing.

  • Use case erectors and sealers for RSC cases when your product is already grouped.

  • Polypack’s RSC case packing systems offer reliable forming, loading, and sealing in one streamlined flow.

Wraparound cases form around the product in one continuous motion. They use less corrugate, are more compact, and are great for tightly packed products like cans, cartons, or bottles.


2. Choose a Case Loader That Matches Your Product

Product shape and fragility determine how the product should be loaded:

  • Top-loaders work well for boxed, stable items.

  • Side-loaders are ideal for bottles, pouches, or grouped products that require tight control during loading.

  • Pick-and-place systems offer the most precision and are common in pharmaceutical or high-value applications.

Polypack offers modular case packers that can be integrated with shrink bundlers, conveyors, or robotic handling systems depending on your layout.



3. Consider Speed and SKU Variety

If you run a limited number of high-volume SKUs, a dedicated high-speed system makes sense. But if your production line handles frequent changeovers, choose equipment that:


  • Has minimal tool change requirements

  • Offers recipe-based programming

  • Can handle multiple case sizes or formats on the same line


Polypack’s modular systems are designed for multi-SKU environments, especially in food, beverage, pet product lines, and personal care items such as aerosol cans.



4. Don’t Forget Case Sealers and Closers


Once your products are in the case, sealing them securely is essential. Your options include:

  • Tape sealers (cost-effective and easy to maintain)

  • Hot-melt glue systems (more tamper-resistant and permanent)

  • Combination systems for flexible packaging lines


The right case sealing solution helps you meet retailer requirements and reduce damage in transit.



5. Think Beyond the Machine: Layout and Service Matter

Efficiency isn’t just about the machine, t’s about how it fits into your line. Look for equipment that:


Polypack offers U.S.-built systems backed by expert service and engineering teams who understand high-speed production challenges.
