With concerns about climate change, resource depletion, and plastic pollution growing, social sustainability cannot be overstated in today's world. One area that has come under intense scrutiny is packaging – the ubiquitous material that wraps and protects everything from our daily groceries to high-end electronics. Sustainable packaging represents a paradigm shift in the way how we think about social sustainability. As its core, sustainable packaging is a holistic approach to packaging design, production, and disposal that considers environmental, social, and economic factors. It encompasses a range of principles aimed at minimizing negative impacts on the planet while still meeting the functional and aesthetic requirements of packaging. Here are some key aspects that define sustainable packaging: resource efficiency, life cycle assessment, biodegradability and recyclability, innovation and collaboration, etc.
Biodegradable shrink wrap
Biodegradability, as one of the key aspects, plays an essential role in the sustainable packaging. Biodegradable Shrink Wrap supports the transition to a circular economy by closing the loop on resource utilization. Instead of following a linear "take-make-dispose" model, biodegradable packaging materials can be biodegraded or recycled back into the ecosystem, where they serve as valuable inputs for new products and processes, minimizing waste and maximizing resource efficiency.
Technological innovation is another key aspect of sustainable packaging. Recently, the first kind of technology of fully biodegradation for PP and PE in the world has emerged, which redefines the biodegradability and sustainability in packaging industry. There are five crucial points for the biodegradation technology:
1, Two post-consumer occasions. utilization and recycling. The process is time-controllable, which can achieve optimal utilization and prompt recycling.
2, Convert plastic to wax. Biodegrade PP and PE to bioavailable wax, which can be assimilate by naturally-existing microorganism easily.
3, Ensure to back to nature safely. After consumption, there is no microplastic or toxic substance left behind.
4, Data support from third-part laboratory. The technology aligns with international biodegradability standard (BSI PAS 9017) based on EN, ASTM and ISO standard (ATSM D5988/ISO17556).
5, Immediate extension availability. The catalyst can be directly added in traditional fossil or biobased raw material (PP and PE) and in the production process to achieve seamless integration.
In summary, fully Biodegradable shrink wrap transforms to bioavailable wax and then microbial converts to water, co2 and biomass in open-air terrestrial environment. during which there is no any microplastic and toxic substance left behind. The core of this technology is the plastic bio-conversion rather than plastic breakdown. Additionally, there is a remarkable advantage of this technology which is plastic retains the same mechanical properties and performance as traditional ones, as well as recyclability.
Sunward has adopted this technology to successfully produce biodegradable POF shrink film, biodegradable PE shrink film, biodegradable PE stretch film, etc. On one hand, Sunward developed the new formulation i.e. adjusted the percentage of various raw material to make up biodegradable products. One the other hand, Sunward improved and optimized the procedure during the process of preparation production. The two measurements contribute to produce Biodegradable shrink wrap film with both high quality and full biodegradability, meeting the advanced international standard.
