According to information published by the China National Intellectual Property Administration (CNIPA), ORIZON Biomaterials (Shandong Orizon Biomaterials Co., Ltd.) has been granted a utility model patent titled “An Air-Supplemented Bubble Stabilization Device for Film Blowing Machines Used in Fully Biodegradable Products.”
The patent authorization number is CN223849965U, with an application date of March 2025.
The patented technology relates to auxiliary equipment for film blowing machines and is specifically designed to improve bubble stability during the processing of fully biodegradable materials, which are known to present higher processing challenges compared to conventional plastics.
Patent Technology Overview
According to the patent abstract, the device includes:
- A housing structure
- An internal telescopic rib assembly
- A drive assembly connected to the telescopic structure
The system uses multiple arc-shaped support columns to increase the contact area between the stabilization structure and the film bubble.
Key Technical Advantages
The patented design provides several practical advantages:
- Reduced contact blind spots through arc-shaped support columns
- Improved stabilization of the bubble center during film blowing
- Enhanced processing stability for fully biodegradable films
By increasing effective contact and support uniformity, the device helps minimize bubble deviation and fluctuation during production.
Supporting Industrial-Scale Biodegradable Film Production
As demand for compostable and biodegradable packaging materials continues to grow globally, manufacturers face increasing requirements for process consistency, film uniformity, and production efficiency. Equipment-level innovations such as this bubble stabilization device play an important role in enabling reliable large-scale manufacturing.
The successful authorization of this patent reflects ORIZON’s continued investment in processing technology optimization and its long-term commitment to advancing biodegradable material applications.
