Packaging Solutions for Coffee, Tea, Dairy Products, and Solid Beverages

The global demand for convenient, single-serve, and high-quality food and beverage products continues to grow. From coffee capsules and tea cups to dairy powders and solid beverages, manufacturers are facing increasing challenges in efficiency, flexibility, hygiene, and product consistency. Choosing the right packaging solution has become a key factor in staying competitive.

At SUNYI, we provide integrated packaging solutions designed specifically for coffee, tea, dairy products, and solid beverages—covering the entire process from filling and sealing to cartoning and case packing.

Diverse Products, One Packaging Challenge

Although coffee, tea, dairy products, and solid beverages differ in form and characteristics, they share common packaging requirements:

• Accurate dosing for powders, granules, and liquids

• High sealing quality to preserve freshness and flavor

• Flexible formats for single-serve cups, capsules, and sachets

• Hygienic, food-grade processing

• Fast changeover for multiple product types

Modern packaging lines must handle a wide product range while maintaining efficiency and stability.

High-Precision Filling for Consistent Quality

For coffee, milk powder, instant tea, and other solid beverages, filling accuracy directly affects taste consistency and cost control. Advanced dosing systems with servo-driven augers, specialized hopper designs, and multi-lane configurations ensure precise and repeatable filling, even for difficult-flow powders.

For liquid dairy or beverage products, rotary or multi-lane filling systems provide stable flow control and high-speed operation, supporting both small and large production volumes.

Advanced Sealing to Protect Freshness

Sealing quality plays a critical role in shelf life and product safety. Depending on the packaging format and material, modern solutions may include:

• Heat sealing or ultrasonic sealing

• Roll-stock film handling systems to reduce material waste

• Modified Atmosphere Packaging (MAP) to lower residual oxygen and extend shelf life

These technologies help maintain aroma, flavor, and nutritional value—especially important for coffee and dairy-based products.

Flexible Packaging for a Changing Market

Consumer demand is shifting toward more variety and customization. Packaging lines must adapt quickly to different cup sizes, capsule formats, and product recipes. Modular machine design and fast changeover systems allow manufacturers to switch formats efficiently, supporting flexible manufacturing and shorter time-to-market.

Multi-lane and dual-lane machines further increase capacity while enabling different products or formats to run on the same machine without complex tooling changes.

Integrated Secondary Packaging Solutions

A complete packaging solution goes beyond filling and sealing. Automated cartoning, case packing, and palletizing systems ensure smooth downstream processing, reduce labor dependency, and improve overall line efficiency.

Robotic pick-and-place technology and collaborative robots enhance flexibility and safety, making the packaging line suitable for FMCG, dairy, and solid beverage applications.

Smart Manufacturing and Quality Control

To meet global standards, modern packaging solutions integrate vision inspection systems, weight checking, and data monitoring. These features help detect defects in real time, ensure compliance, and support Industry 4.0-ready production with data visualization and traceability.

Conclusion

Packaging solutions for coffee, tea, dairy products, and solid beverages must balance precision, flexibility, hygiene, and efficiency. By combining advanced filling technology, intelligent sealing systems, flexible machine design, and automated secondary packaging, manufacturers can build scalable and future-ready production lines.

SUNYI is committed to delivering one-stop, intelligent packaging solutions that help customers improve productivity, reduce costs, and maintain consistent product quality across global markets.
