Biodegradable Heat Shrink Film: A Revolutionary Breakthrough in Environmental Protection and Performance

Driven by the "double carbon" goal, the environmental protection upgrade of packaging materials has become the core of industrial transformation. Qingdao Fullsun's biodegradable heat shrink film reconstructs the industry pattern through four dimensions: material characteristics, technological breakthroughs, application scenarios and industry prospects, and its innovative value is reflected in:
The material properties achieve a balance between environmental protection and functionality. The mainstream uses biomass as raw material, reducing carbon emissions by more than 80% throughout the life cycle, and its molecular chain "memory effect" ensures thermal shrinkage performance. The shrinkage rate is more than 75%, and the amorphous structure takes into account high transparency and flexibility, reducing the recycling cost by 30%. Third-party testing shows that the light transmittance of the film reaches 92%, the anti-ultraviolet film extends the shelf life of bottled water by 40%, the bio-based content of recycled label film is 42%, and the degradation rate is 93% in 180 days.
Technological breakthroughs have completed the industrialization leap. The domestic team broke through the degradation technology of the whole natural area to achieve a degradation rate of more than 90% in soil, freshwater and ocean, and passed the extreme environment test. The raw material synthesis cycle is shortened by 40%, and the patented five-layer co-extrusion technology reduces the film defect rate to 0.15% and the unit energy consumption is reduced by 27%.
The application scenario forms a two-line expansion model. PVC labels are replaced in the food and beverage field, modified biodegradable materials are used in the field of electronics and electrical appliances to meet the protection of precision components, and the ESD protection level of Huawei's supply chain is 1×10⁶Ω. Cutting-edge applications such as medical packaging bags and soil moisture retention films are promoting the extension of materials to functional scenarios.
The industrial prospects are driven by both policy and market. China's "Plastic Pollution Control Action Plan" requires the proportion of degradable products to reach 30% by 2025, and predicts that the size of China's shrink film market will reach 2.41 billion yuan in 2029, reducing the recycling cost by 18% compared with virgin materials, and increasing the recycling efficiency of the EU market by 35%.
Material innovation is driving the green transformation. From laboratory optimization to smart factory automation, from packaging to cross-domain applications, degradable heat shrink film reshapes the industrial ecology through technological iteration. Grasping the boundaries of material performance and the path of industrialization will become the key to seizing the green economy track.
