Consumers must often complain about the packaging of chips; it is always full of air with a few chips. In fact, this is the result of careful consideration by chips manufacturers.

Using nitrogen filling technology, about 70% nitrogen is filled into the package, supplemented by aluminum plating process to improve the barrier of the package, which can protect chips from extrusion during transportation and maintain the integrity and crisp taste.

However, while we enjoy delicious chips, our environment is experiencing unbearable weight.

Traditional potato chips packaging is mostly petroleum-based non-degradable plastic, which is difficult to degrade. According to Statista data, in 2020-2021, about 162,900 tons of chips were sold in the UK, and the number of discarded chips bags was huge, causing enormous pressure on the environment.

When low-carbon environmental protection has become a new trend, how to ensure that people can enjoy delicious food without affecting the environment has become the new goal of potato chip brands.

The use of bio-based degradable materials in packaging bags is one of the ways to solve the problems of chips packaging. BiONLY, the first new bio-degradable film to achieve mass production in China launched by Xiamen Changsu provides solutions.

BiONLY uses bio-based polylactic acid as raw material, which has the characteristics of controllable degradation. Under Changsu’s years of technical accumulation, it has overcome the problems of insufficient stiffness and poor tensile strength of ordinary degradable film. With Changsu’s world-leading biaxial stretching technology, its thickness is only 15 microns, making it the thinnest bio-based degradable film in the industry. Under the conditions of industrial composting, BiONLY can be completely degraded into water and carbon dioxide within 8 weeks, which is friendly to the natural environment and pollution-free.

Meanwhile, BiONLY has excellent adhesion to aluminum plating. Through aluminum plating, the oxygen resistance of the film is greatly improved and laminated with other bio-based degradable materials, which not only realizes the carbon reduction of packaging, but also protects the nitrogen in the bag from leakage and ensures the crisp taste of potato chips.
