Automation upgrade under beverage packaging innovation: Intelligent counting case of triangle bags

In today’s beverage industry, packaging is no longer just a container—it has become a key expression of brand differentiation and consumer experience. In recent years, Tetra Pak triangular packs and other irregular-shaped packaging formats have gained rapid popularity, especially among younger consumers.

Why Are Triangular Packs So Popular?

1. Ergonomic & portable – The unique triangular shape fits comfortably in the hand, and can be easily slipped into a pocket or bag.

2. Freshness + convenience – Single-serving packs avoid waste, while lightweight design suits fast-paced lifestyles.

3. Shelf impact – On a crowded shelf filled with bottles and boxes, the triangular pack stands out with its distinctive shape and vibrant graphics, instantly drawing attention.

                                                                          

This innovative design not only redefines juice packaging but also opens new possibilities for product development.

The Production Challenge of Irregular Packaging

However, the shift from regular to irregular formats brings new manufacturing challenges:

• Counting errors – Conventional counting systems often miscount, causing underfills or overfills.

• Blockages & downtime – Irregular shapes may jam during conveying or counting, interrupting production.

• Low flexibility – Switching to a new pack shape often requires major equipment adjustments.

These issues make it difficult for beverage companies to scale up irregular packaging.

Hengli Packaging provides a breakthrough professional with its counting machine technology
Recently, a beverage company approached us with a request to automate  the counting and cartoning of triangular juice packs. Their biggest concerns were inaccurate counts, low efficiency, and poor line stability.

Through real-sample testing, we proved that our counting machine could:

• Convey irregular packs smoothly on vibration channels

• Deliver accurate, high-speed counting

• Ensure stable operation with no blockages

The results exceeded expectations, completely eliminating customer concerns and confirming that our solution could handle diverse irregular packaging in the future.

We have successfully applied similar solutions to other irregular products. For example, our counting system for Wufangzhai's assorted rice dumpling gift boxes achieved precise counting and high-speed cartoning.

As irregular packaging continues to shape the beverage market,intelligent counting and cartoning solutions will be essential for efficient production.
At Hengli Packaging, we stand by our motto: “if it can be counted, it can be packed.” We remain committed to delivering reliable automation solutions that empower food and beverage companies with smarter, more efficient packaging.
