Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air bubble films do not provide adequate fire protection, allowing express packages to easily burn when exposed to open flames during transportation, leading to potential fire disasters.
Innovation Solution
A fire extinguishing air bubble film filled with a gaseous fire-extinguishing medium, comprising a double-layer air bubble film base material with buffer air bubbles containing a specified mixture of polyethylene, resin, biodegradable additive, plasticizer, flame retardant, anti-block agent, and whitening agent, and filled with gaseous fire-extinguishing agents like chlorodifluoromethane or inert gases, manufactured through a multi-step process involving mixing, melting, extrusion, and vacuum forming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional air bubble film is used, then the packaging provides moisture-proof and buffering functions, but the film facilitates combustion when exposed to open flames during transportation
Solution Approach 1:
The patent fills the air bubbles with inert gases (such as nitrogen, carbon dioxide, or other non-flammable gases) to create an inert environment within the packaging film. This inert atmosphere prevents combustion by removing oxygen and other flammable components, directly resolving the contradiction between providing fire protection and maintaining the packaging's protective functions.
Solution Approach 2:
The patent uses composite materials by combining polyethylene base material with flame retardant additives and incorporating gaseous fire-extinguishing media within the bubble structure. This composite approach enhances fire resistance while preserving the original packaging functions of moisture-proofing and buffering.
2Reliability
If flame retardant additives are added to the air bubble film, then fire resistance is improved, but the manufacturing process complexity increases
Solution Approach 1:
The patent incorporates flame retardant additives during the initial mixing and extrusion stages of manufacturing, before the packaging is put into service. This preliminary action ensures fire resistance is built into the material structure from the start, avoiding the need for complex post-processing or treatment steps later in the product lifecycle.
Solution Approach 2:
The patent optimizes the concentration and type of flame retardant additives within specific ranges to achieve effective fire resistance while minimizing manufacturing complexity. By carefully controlling material parameters and formulation ratios, the patent simplifies the manufacturing process while maintaining high fire protection performance.
3Reliability
If gaseous fire-extinguishing medium is filled in air bubbles, then fire extinguishing performance is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs a vacuum forming process where the film itself is drawn into bubble shapes, and the gaseous fire-extinguishing medium is automatically filled into these formed bubbles through vacuum suction. This self-service mechanism eliminates the need for complex external filling equipment and precise manual control, reducing manufacturing precision requirements while maintaining effective fire extinguishing performance.
Solution Approach 2:
The patent uses vacuum pneumatic technology to form the bubbles and fill them with gaseous fire-extinguishing medium. The vacuum pressure automatically draws the gas into the bubble structures, providing a precise and controlled filling process that reduces the need for complex mechanical positioning and alignment systems.

Implementation Method 1
buffer air bubbles distributed in the double-layer air bubble film base material and internally filled with the gaseous fire-extinguishing medium
Implementation Method 2
a softened double-layer air bubble film base material was slowly winded on a vacuum forming roller, such that the film close to round holes on the vacuum forming roller was sucked up to form small vacuum air bubbles
