Application and Development of Oral Liquid Cartoning Machine in the Pharmaceutical Industry

Oral liquid cartoning machine are key equipment in the transition of liquid preparations (oral liquids, syrups, soft ampoules, etc.) from "inner packaged finished products" to "commercialized outer packaging." Their application in the pharmaceutical industry has evolved from simply "stuffing bottles into boxes" to a link in a continuous line encompassing filling, labeling, cartoning, coding, and boxing. The following discussion covers their current application status, key technologies, and development trends.

I. Current Application Status in the Pharmaceutical Industry

Application Stage: Typically placed after filling, capping, and labeling, in conjunction with wrapping/boxing/palletizing, automatically placing and sealing the medicine bottles (1-10 vials/box) + instructions + straws/measuring cups and other accessories.

Mainstream Models:

Vertical Cartoning (round bottles loaded upright, most commonly used, 10-50 cartons/minute)

Horizontal Continuous Cartoning (vials/ampoules/soft ampoules loaded horizontally, 80-300 cartons/minute)

Multi-bottle Combination/Treatment Course Cartoning (with dividers for anti-collision)

Industry Pain Points Driving Manual Replacement: Oral liquid bottles are fragile, have uneven liquid levels, and are prone to leakage; manual cartoning is slow and carries a high risk of cross-contamination; the new GMP, the 2025 edition of the Pharmacopoeia, and the appendix to pharmaceutical packaging materials are forcing a shift towards "less manned/unmanned" operations.

Market Size: The global pharmaceutical continuous cartoning machine market is projected to reach approximately RMB 11.5 billion in 2031, of which liquid formulations (oral liquids/syrups, etc.) are projected to reach approximately RMB 1.89 billion in 2024 and RMB 3 billion in 2031 (CAGR 6.8%); the Asia-Pacific region, especially China, is a medium-to-high-speed growth engine, with the Chinese market accounting for approximately 18% of the global market in 2024.

II. Special Technical Requirements for Oral Liquid Scenario (Compared to Solid Dosage Forms)

More Difficult Material Handling: Glass bottles/soft ampoules are prone to tipping and impact, requiring variable pitch screws, differential speed belts, and vision-based robotic flexible gripping to achieve "random incoming materials → equally spaced single-row" handling.

Leak Prevention and Cushioning: Multi-bottle packs often use foam trays/blister trays, with robotic arms handling the trays before placing them into boxes; integrated checkweighing before sealing can prevent leakage when filling empty bottles.

GMP Strict Constraints:

Separate transmission and packaging areas; cleanroom with negative pressure/Class D or higher; contact parts made of 316L or 304 stainless steel, Ra≤0.8μm.

Full-process electronic recording, audit trail, batch traceability, compliant with FDA/EU GMP/21 CFR Part 11

Integrated Inspection and Rejection: Visual inspection for missing bottles, missing instructions, and unclear batch numbers; dynamic weighing to check for underfilling; 100% rejection of non-conforming products.

III. Development Trends for 2025-2026

1. From stand-alone machines to integrated production lines: Directly connecting upstream filling and labeling machines with downstream wrapping, unpacking, packing, and palletizing to form a continuous line with "zero intermediate turnover." Example: The oral liquid line at Shidai Sunshine Pharmaceutical processes 500 vials per minute, doubling efficiency.

2. Full servo + modular quick-change electronic cams replace mechanical cams, storing 200 formula sets, with changeover times of 3-15 minutes, compatible with round bottles/irregularly shaped bottles/soft ampoules on the same line.

3. AI vision and digital twin AI quality inspection achieve 99.9% accuracy, with OEE Kanban + predictive maintenance + remote diagnostics; Shanghai Pharmaceuticals has already implemented 3D vision robots for carton feeding, achieving ±0.1mm positioning and adapting to 380 cartons per minute.

4. The embedded coding traceability system directly completes the "box-carton-pallet" three-level code association within the packaging cycle, uploading OPC-UA to the MES/drug regulatory platform, eliminating the need for a separate coding station.

How to choose a machine based on your customer's level:

Small batches of multiple varieties/clinical drugs: Semi-automatic or vertical 10–50 boxes/min, flexible model changeover.

Large orders of conventional Chinese patent medicine oral liquids: Domestic continuous horizontal 100–200 boxes/min + checkweighing and coding. Export to Europe and America/sterile preparations: Prioritize FDA/CE + MES interface + Ullman/Bosch-level or equivalent domestic head configuration.
