With the rise of environmental awareness, biodegradable packaging materials have become an industry trend, of which PLA (polylactic acid) laminated paper and nano plastic-free coating are the two mainstream technologies, but there are significant differences between the two in terms of performance and environmental protection.
Limitations of PLA Lamination Paper
PLA Lamination Paper is coated with bio-based PLA, which is biodegradable but relies on industrial composting environments (requiring high temperatures above 50°C and specific microorganisms), and the decomposition efficiency is extremely low in natural environments. In addition, PLA has poor temperature resistance and is prone to softening at high temperatures (over 60°C) and brittleness at low temperatures (e.g., frozen environments), limiting its application scenarios.
Advantages of Nano Plastic Free Coating
In contrast, Nano Degradable Plastic Free Coating adopts natural polymer composite technology, which can be rapidly degraded in the natural environment without industrial composting, and the decomposition products are harmless. It has a wider temperature resistance range of -20°C to 120°C, making it suitable for scenarios such as hot beverage cups and frozen food packaging. In addition, the nano-coating has better barrier properties, is effective against oil and water, and has higher mechanical strength than PLA lamination.
Nano plastic-free coating is superior to PLA lamination paper in terms of environmental friendliness (natural degradation) and practicality (resistance to high and low temperatures), and is a better solution to replace traditional plastics. In the future, as the cost of the technology decreases, plastic-free coatings may become the core choice for sustainable packaging.
