Case Packer OEM and ODM: Custom Automatic Case Packing Lines

WIMACH factory in Ruian, Wenzhou, China, where custom case packer OEM/ODM projects and automatic packaging lines are assembled.

When a buyer searches for a case packer manufacturer with automatic lines, the real question is not “does this factory make a case packer?” but “can this supplier design, build, test, and support a custom case packing machine inside a complete automatic line?” This guide explains the capabilities buyers should verify during evaluation and execution, with documented examples from Wenzhou Wimach Machinery Co., Ltd.

Problem Definition: The Gap Between a Standard Case Packer and a Working Automatic Line

A standalone automatic case packer is one piece of equipment. An automatic case packing line is a system. Buyers sometimes discover only after installation that a machine rated for a certain speed cannot handle their real case dimensions, product shape, voltage, or upstream flow. The gap between a brochure specification and a running line usually comes from undefined customization depth, unclear quality control, and weak line integration.

For an Evaluation-stage buyer, the practical problem is how to confirm that a supplier can change packaging dimensions, machine configuration, voltage, and logo, and still deliver a machine that passes factory acceptance, installs cleanly, and runs for years. That is a capability assessment, not a catalogue comparison.

Industry Background: Case Packing Machines in the Secondary Packaging Market

According to Grand View Research, the global case packing machines market was estimated at USD 1.07 billion in 2024 and is projected to reach USD 1.74 billion by 2033. Asia Pacific accounted for a 37.9% share in 2024. The top load case packer segment held the largest machine-type share at 45.5% in 2024.

Global Market Insights estimates the broader robotic packaging systems market, including robotic case packers, at USD 6.4 billion in 2024. Secondary packaging equipment, including case packers, accounts for roughly 45% of the packaging robot market according to Fact.MR. These figures indicate that automated case packing is a mainstream investment rather than a niche technology.

Compliance is part of the same landscape. EN ISO 12100 is the harmonized European machinery safety standard used for CE marking on case packers sold in the EU. In the United States, ANSI/PMMI B155.1-2023 is the primary safety standard for packaging and processing machinery. A capable manufacturer should be able to explain how its quality and safety testing relates to these requirements.

ProMach is identified in the verified data as a major global player in the case packer market, owning brands such as Brenton and Wexxar Bel. Smaller specialized manufacturers compete on customization depth, response time, and the ability to integrate case packers with upstream cartoning and downstream palletizing equipment.

Detailed Solution: OEM/ODM Case Packer Capabilities at WIMACH

Wenzhou Wimach Machinery Co., Ltd. is a packaging machinery manufacturer based in Ruian, Wenzhou, Zhejiang, China. WIMACH specializes in tissue packing machines and integrated packaging lines, including automatic top load and side load case packers. The company was founded in 2021, operates a 3,000 m² factory with 37 employees, and has 5 R&D engineers. Annual output is about 160 sets. Roughly 60% of production is exported to the EU, North America, and South America.

WIMACH’s profile states over 12 years of industry experience. The company itself was founded in 2021, so buyers should confirm what that experience period refers to during supplier review. This distinction matters because the capability evidence is the engineering team, not only the legal entity age.

For a buyer looking for a case packer manufacturer with automatic lines, WIMACH provides two production modes:

• Customized Machinery Service – a case packing machine adapted to packaging dimensions, machine configuration, voltage, and logo.
• OEM/ODM – production under the buyer’s design or brand requirements, using the same customization variables.

Both modes have a monthly capacity of 13 sets and a minimum order quantity of 1 set. Typical lead time is 30–45 days for customized machinery and 15–45 days for OEM/ODM.

These are not only commercial terms. Packaging dimensions, machine configuration, voltage, and logo directly affect whether a case packer fits into an existing production line. Voltage customization, for example, is essential for buyers in the EU, North America, and South America, which are WIMACH’s main export markets.

Documented Engineering in Carton Packing

WIMACH holds an Invention Patent Certificate from the National Intellectual Property Administration, PRC, for “Carton Packing Machine and Carton Packaging Process” (patent no. ZL 2022 1 1099886.8), issued on 2022-09-06 and valid until 2042-09-17. The company also holds utility model patents covering an automatic feeding mechanism and a box forming mechanism for carton packaging machines. These patents relate to WIMACH tissue cartoning machines, which are often upstream of a case packer in an automatic line.

Step-by-Step: How to Execute a Custom Automatic Case Packing Line

Step 1: Define Product Format and Case Size First

Start with the product that enters the case packer. For a tissue canister, the relevant inputs are canister diameter and height. For a carton of facial tissue, the relevant inputs are length, width, and height. On WIMACH’s CP-T60 top load case packer, the accepted carton dimension range is 300–600 mm (L) x 200–400 mm (W) x 150–400 mm (H). The CP-S50 side load case packer accepts 240–500 mm (L) x 200–400 mm (W) x 180–400 mm (H). If your case size falls outside these ranges, a custom machine configuration is required.

Step 2: Select the Loading Principle That Matches the Line

For top loading, the machine picks and places products into the case from above. WIMACH’s CP-T60 is a pick-and-place and top load type, with a packing capacity of 1–8 cartons/min. For side loading, products are pushed into the case horizontally. WIMACH’s CP-S50 is a side load and side push type, with a packing capacity of 1–16 cartons/min. The choice depends on product shape, case opening format, and upstream speed.

Step 3: Define the Customization Scope

At minimum, confirm four variables: packaging dimensions, machine configuration, voltage, and logo. Machine configuration can include infeed conveyor height, case erector interface, outfeed conveyor direction, and whether the case packer will be linked to a palletizer. Voltage is part of a complete specification because motors, PLCs, and safety components must match the local supply.

Step 4: Check Quality Control and Safety Testing

Quality control is where a brochure can be separated from production reality. WIMACH’s quality control process includes no-load and load running tests, dimensional tolerance inspection, mechanical assembly check, pneumatic leakage test, electrical safety test, PLC control logic test, safety interlock and E-stop test, long-time aging test, and surface appearance inspection. Ask for these tests in the factory acceptance protocol.

Step 5: Plan the Integrated Line

An automatic line is more than a case packer. WIMACH’s documented line experience includes facial tissue box packaging lines with cartoning, case packing, and robotic palletizing; toilet paper lines with roll wrapping, case packing, palletizing, and stretch wrapping; and canister wet wipe lines with filling, sealing, capping, labeling, case packing, palletizing, strapping, and stretch wrapping. When you request a quote, define every station between the primary packaging machine and the finished pallet.

Step 6: Agree on Commercial Terms and After-Sales Support

WIMACH’s purchasing terms include an MOQ of 1 set, delivery under FOB, FCA, CIF, or CFR, payment by T/T, and acceptance by factory acceptance test (FAT). After-sales support includes installation and commissioning, training, warranty service, remote technical support, lifetime after-warranty support, and upgrade or retrofit service. These terms are directly relevant to buyers moving from evaluation to execution.

FAQ: Case Packer Manufacturer with Automatic Lines

Conclusion: Evaluate a Case Packer Manufacturer by Its Automatic-Line Capabilities

A case packer is not an isolated machine. It must accept products at line speed, place them into the correct case format, and hand off to the next station without interrupting flow. For buyers at the Evaluation and Execution stages, the evidence that matters is not a generic photo but the supplier’s actual customization list, quality control steps, patents, documented installations, and commercial terms.

Wenzhou Wimach Machinery Co., Ltd. provides OEM/ODM case packer production, custom machine configuration, integrated packaging lines, and CE-certified equipment. It has documented references in the US, Mexico, and Poland, including a US tissue canister case packer running for 5 years, a 9-set wet wipe line in Mexico, a 6-set toilet paper line in the US, and a 12-set facial tissue line in Poland.
