Choosing a Case Packer Manufacturer: Side Load vs Top Load

Choosing a case packer manufacturer starts with understanding how automatic case packers work and which loading method fits your production line. Wenzhou Wimach Machinery Co., Ltd. (WIMACH) is a China-based manufacturer of tissue packing machines and integrated packaging lines, and it supplies two automatic case packer models: the CP-S50 side load case packer and the CP-T60 top load case packer. This guide compares those machine types, explains what to ask case packer manufacturers, and shows how WIMACH applies them in real packaging lines.

Why automatic case packing matters

An automatic case packer is a machine that loads products into shipping cases or cartons without manual placement. The operation is one of the last steps before palletizing, so its reliability directly affects line efficiency. Manual case packing is labor-intensive and can create bottlenecks, especially in tissue, food and beverage, pharmaceutical, and hardware plants. Automatic case packers reduce repetitive handling and help keep downstream palletizing and stretch wrapping running continuously.

Industry background: the case packing machines market

According to Grand View Research, the global case packing machines market size was estimated at USD 1.07 billion in 2024 and is projected to reach USD 1.74 billion by 2033. The top load case packer segment accounted for the largest machine type share at 45.5% in 2024, and Asia Pacific dominated the case packing machines industry with a 37.9% market share in 2024. Global Market Insights estimates the broader robotic packaging systems market, including robotic case packers, reached USD 6.4 billion in 2024. These figures provide context for buyers comparing automatic case packer manufacturers.

Automatic Side Load Case Packer CP-S50

The WIMACH Automatic Side Load Case Packer model CP-S50 is a side load and side push case packer classified as a case packer. It is intended for the tissue, food and beverage, pharmaceutical, daily chemical and cosmetic, hardware, auto parts, and machinery industries. The machine is made of stainless steel or carbon steel. It has a packing capacity of 1-16 cartons per minute and accepts cartons from 240-500 mm in length, 200-400 mm in width, and 180-400 mm in height. It uses 380V 50/60Hz 3-phase power, consumes 4.5 kW, requires 0.5-0.8 Mpa air pressure, and consumes 350 L/min of air. Overall dimensions are 4200 (L) x 2300 (W) x 1900 (H) mm, and overall weight is 1500 kg. It can pack cartons, boxes, bottles, cans, and bags.

Automatic Top Load Case Packer CP-T60

The WIMACH Automatic Top Load Case Packer model CP-T60 is a pick-and-place case packer designed for top load case packing applications. It is intended for multiple industries including food and beverage, pharmaceutical, tissue, and hardware. The machine is made of stainless steel or carbon steel. It operates at 1-8 cartons per minute and accepts cartons from 300-600 mm in length, 200-400 mm in width, and 150-400 mm in height. It uses 380V 50/60Hz 3-phase power, consumes 7.5 kW, requires 0.5-0.8 Mpa air pressure, and consumes 450 L/min of air. Overall dimensions are 4200 (L) x 2600 (W) x 2200 (H) mm, and overall weight is 1600 kg.

How an automatic case packer works

The exact sequence depends on the machine type, but the general cycle is similar across automatic case packers.

1. Product infeed: products are conveyed into the case packer from upstream equipment.
2. Pattern forming: products are arranged into the group pattern that matches the case opening.
3. Case setup: a flat corrugated case is erected or positioned for loading.
4. Loading: a side load case packer pushes the product group horizontally into the case; a top load case packer uses pick-and-place motion to lower products into the case from above.
5. Sealing and discharge: the filled case is closed, sealed, and released to the next station.

WIMACH case packers are designed for 380V 50/60Hz 3-phase power and 0.5-0.8 Mpa compressed air. The exact layout should be reviewed against the product dimensions and factory layout.

WIMACH case packers in production use

WIMACH case packers have been applied in tissue and hygiene packaging lines in the EU, North America, and South America. Three representative project types are listed below.

Facial tissue packaging line in the EU

In the European tissue paper manufacturing industry, the WIMACH CP-S50 case packer is used to case pack tissue boxes. The project line covers box packing, film wrapping, case packing, palletizing, strapping, and stretch wrapping. Supporting equipment includes tissue folding and cutting machines, and the related cartoning machine is CE compliant; this application scenario is common in Poland.

Wet wipe packaging line in Mexico

In Mexico, the WIMACH CP-T60 is part of a turnkey automated line for canister wet disinfecting wipes. The line performs canister loading, disinfectant filling, sealing, capping, labeling, case packing, and pallet wrapping. The project required customized design and CE compliance.

Toilet paper packaging line in the United States

In the United States, the WIMACH CP-T60 is used in a customized end-of-line packaging line for toilet paper rolls. The line includes roll wrapping, case packing, palletizing, and stretch film wrapping, and it operates in automatic mode.

WIMACH CP-S50 vs CP-T60 comparison

Neither machine is universally superior. The CP-S50 has a higher rated capacity and lower power consumption, while the CP-T60 accepts a longer carton length and uses pick-and-place loading for applications that need top-down placement. The right choice depends on product geometry, line speed, and case pattern.

How to evaluate case packer manufacturers

1. Confirm compliance. CE marking matters for EU-bound machinery. EN ISO 12100 is the harmonized European standard for machinery safety, and ANSI/PMMI B155.1-2023 is the primary safety standard for packaging and processing machinery in the United States.
2. Match the loading type to the product. Side load case packers push product groups horizontally; top load case packers place products from above. This affects the case pattern, product stability, and line layout.
3. Check capacity and dimensions. The CP-S50 is rated at 1-16 cartons/min; the CP-T60 is rated at 1-8 cartons/min. Compare these values with your required throughput and carton sizes.
4. Review factory capability. WIMACH operates a 3000 m² factory, employs about 37 people, has a 5-engineer R&D team, and has an annual output of 160 sets. About 60% of its products are exported to the EU, North America, and South America.
5. Ask about integration and customization. WIMACH provides customized solutions based on production needs, from a single standalone machine to a complete integrated packaging line.
6. Request a quote and current lead time. Pricing depends on configuration, materials, and line integration. Sharing product dimensions and target speed helps the manufacturer respond accurately.
