Amid the global wave of focusing on the "dual carbon" goals and circular economy, the packaging industry is undergoing a transformative revolution centered on "green efficiency." The replacement of traditional plastic bottles and glass bottles with flexible packaging not only reshapes the form and functional logic of packaging but also achieves breakthroughs in key areas such as carbon reduction, logistics optimization, and recycling. It has become a crucial vehicle for practicing the concept of sustainable development.

The lightweight nature of flexible packaging is the core advantage in achieving carbon reduction throughout its entire life cycle. Compared with plastic bottles, flexible packaging has a significant edge in raw material consumption. Taking the common spouted flexible pouch as an example, its plastic usage can be reduced by more than 60% compared to PET bottles of the same capacity, greatly lowering the reliance on non-renewable resources like crude oil during the production stage. When replacing glass bottles, this carbon reduction effect is even more pronounced: glass bottles are heavy and require high energy consumption in production, and the carbon emissions from the raw material melting process alone far exceed those of flexible packaging. Moreover, the lightweight characteristic of flexible packaging extends to the transportation stage — with the same load capacity, the transportation weight of goods in flexible packaging can be reduced by over 70%, directly cutting down logistics fuel consumption and exhaust emissions, and forming a full-chain carbon reduction loop from "production to transportation."

In the large-scale application of single-material flexible packaging, the technical adaptability of production equipment has become a key support. NCA's automatic spout welding machine provides a core solution for the green production and recycling of spout pouches.

For example, the model NCA1604D-90 employs precise disc positioning and an automated alignment system to achieve efficient welding of spouts and bag bodies, with stable welding strength and excellent sealing performance. This not only ensures the practicality of the packaging, but also avoids material waste and discarding caused by process defects. In addition, the modular design of the equipment can adapt to various spout pouch forms such as straight-spout bags and angled-spout bags, and a single piece of equipment can complete the entire automated process from feeding, positioning, welding to discharging, with a production efficiency of 90 pieces per minute. This greatly reduces the energy consumption and labor cost per unit product, and further improves the full-chain advantages of flexible packaging in "low-carbon production and circular recycling".
