Description

Technical Field

[0001] The utility model relates to the technical field of umbrellas, in particular to a bio-based PE film umbrella. Background Art

[0002] As the world's awareness of environmental protection increases, the environmental problems caused by traditional plastic materials due to their non-degradability are becoming increasingly prominent. In response to the call for sustainable development, bio-based materials, as a new type of degradable and environmentally friendly material, have received widespread attention. The raw materials of bio-based PE film umbrellas come from renewable biomass resources, such as sugarcane, etc. These raw materials can absorb carbon dioxide in the atmosphere during their growth and reduce the greenhouse effect. At the same time, bio-based PE film umbrellas can be quickly degraded by microorganisms in the natural environment after being discarded, returning to nature, and will not cause long-term pollution to the environment.

[0003] The main structure of the umbrella frame of the existing film umbrella is a relative structure. When it is kept open, the top protrusion abuts and limits the lower end of the ring sliding on the outside of the umbrella handle to maintain the stability of the structure in the open state. However, when in use, the top protrusion is easily pressed into the umbrella handle by external forces, causing the entire umbrella surface to shrink, affecting normal use.

[0004] Therefore, a bio-based PE film umbrella is needed to improve the above problems. Utility Model Content
