Automatic Side Load Case Packer model CP-S50 – a versatile case packing machine for cartons, boxes, bottles, cans and bags.

What Is a Case Packer? A Guide to Automatic Case Packing Machines

An automatic case packer (also called a case packing machine or case packaging machine) is a piece of industrial equipment that automatically loads products – such as cartons, boxes, bottles, cans, or bags – into shipping cases or cartons. It is a vital component of end‑of‑line packaging, helping manufacturers increase throughput, reduce labor cost, and improve pack consistency. This guide explains the types of case packers, their typical applications, and what to consider when evaluating case packer manufacturers like WIMACH.

The Problem: Inefficient Manual Case Packing

In many production lines, manual case packing creates bottlenecks, ergonomic risks, and variable pack quality. Workers must pick, orient, and place products into cartons at a speed that is hard to sustain. As output demands grow, manual packing becomes a limiting factor. Automated case packers solve this by handling the repetitive motion reliably, often integrating with upstream wrapping and downstream palletizing equipment.

Industry Background: The Growing Case Packer Market

The global case packing machines market was estimated at USD 1.07 billion in 2024, with projections reaching USD 1.74 billion by 2033 (Grand View Research). Asia Pacific led the industry with a 37.9% revenue share. Among machine types, the top load case packer segment accounted for the largest share at 45.5% in 2024. The broader robotic packaging systems market, which includes robotic case packers, reached USD 6.4 billion in the same year (Global Market Insights). Secondary packaging equipment – which includes case packers – holds approximately 45% of the total packaging robot market (Fact.MR). These figures underscore the growing adoption of automated case packing across industries such as food & beverage, pharmaceutical, tissue, hardware, and personal care.

WIMACH Case Packer Solutions

Wenzhou Wimach Machinery Co., Ltd. (brand: WIMACH) is a manufacturer specializing in tissue packing machines and integrated packaging lines. Founded in 2021, the company operates a 3000 m² factory with 37 employees and counts 5 engineers on its R&D team. Approximately 60% of production is exported to the EU, North America, and South America. All WIMACH machines are CE certified and assembled with reliable components from well-known brands. The company offers two main case packer models:

1. Automatic Side Load Case Packer – Model CP-S50

The CP-S50 is a side load / side push case packer classified as a Case Packer. It is designed for the tissue, food & beverage, pharmaceutical, daily chemical & cosmetic, hardware, auto parts & machinery industries. The machine is built from stainless steel or carbon steel and can pack cartons, boxes, bottles, cans, and bags. Key parameters: packing capacity 1–16 cartons/min, carton dimension range 240–500 mm (L) × 200–400 mm (W) × 180–400 mm (H), power 380 V 50/60 Hz 3-phase, consumption 4.5 kW, air pressure 0.5–0.8 MPa, air consumption 350 L/min. Overall dimensions 4200 (L) × 2300 (W) × 1900 (H) mm, weight 1500 kg.

Automatic Top Load / Pick‑and‑Place Case Packer model CP‑T60 – ideal for fragile or irregularly shaped products.

2. Automatic Top Load Case Packer – Model CP-T60

The CP-T60 is a pick‑and‑place / top load case packer designed for top loading applications. It suits food & beverage, pharmaceutical, tissue, and hardware industries. Construction materials: stainless steel or carbon steel. Rated voltage 380 V 50/60 Hz 3‑phase, net weight 1600 kg, overall dimensions 4200 (L) × 2600 (W) × 2200 (H) mm, packing capacity 1–8 cartons/min. The CP-T60 is often used when products must be gently placed from above into cases, such as assembled cartons, wrapped tissue rolls, or containers that cannot be pushed sideways.

Step‑by‑Step: How an Automatic Case Packer Works

While designs vary, the typical operation sequence of an automatic case packer includes:

• Case erection – A flat cardboard blank is picked, formed, and taped or glued into an open case (this step may be integrated or handled by a separate case erector).
• Product infeed – Items arrive on a conveyor in single file or in collated groups, depending on the pack pattern.
• Loading – Depending on machine type, products are either pushed sideways into the case (side load), dropped from above (drop case packer), or picked and placed by a robotic arm (robotic case packer / robot case packer).
• Case closing – The loaded case moves to a flap tucker and sealing station (tape or hot melt).
• Ejection – The sealed carton is discharged to the next process, typically a palletizer or labeling system.

WIMACH’s CP-S50 and CP-T60 integrate into such automated lines, often paired with feeders, wrappers, and palletizers. For example, in a facial tissue packaging line deployed in the EU, the CP-S50 case‑packs tissue boxes, taking them from the wrapping machine and feeding sealed cartons to a palletizer for full automation (corpus ID 158015).

Real‑World Use Cases

• Facial Tissue Packaging Line (EU)

In Poland, a complete turnkey line for facial tissues uses a WIMACH case packer (model CP-S50) to case‑pack tissue boxes after they are cartoned and film‑wrapped. The entire line – including box packing, film wrapping, case packing, palletizing, strapping, and stretch wrapping – runs automatically, requiring minimal manual intervention. The equipment is customized and CE‑certified (corpus ID 158012, 158013, 158014, 158015).

• Toilet Paper Packaging Line (US)

For a US‑based toilet paper manufacturer, a WIMACH top load case packer (model CP-T60) case‑packs wrapped toilet rolls. The line begins with roll wrapping, then uses the case packer, an automatic palletizer, and a stretch wrapper to create stable pallet loads (corpus ID 158018). The solution is customized and CE compliant.

• Canister Wet Wipe Packaging Line (Mexico)

A Mexican wet wipe manufacturer uses a fully integrated line that includes an automatic case packer for canisters of disinfecting wipes. After filling, sealing, capping, and labeling, the canisters are conveyed to the case packer for carton packing. The line also features a pallet wrapper for shipping stability (corpus ID 158019). The case packer model in this line is the CP-S50, handling rigid canister containers.

Comparison: Side Load vs. Top Load Case Packer from WIMACH

For high‑speed, fragile, or irregularly shaped products, the top load CP-T60 provides gentle handling, while the side load CP-S50 delivers higher throughput (up to 16 cpm) and is well suited for regular‑shaped items that can be pushed.
