AI Technical Summary
Technical Problem
Existing cushioning materials are difficult to fit closely to irregularly shaped or angular product surfaces, resulting in insufficient wrapping and inability to effectively protect products from damage during transportation.
Method used
Design a foam bag comprising a first bag body and a second bag body. The second bag body has cavities for components A and B. By controlling the strength difference of the sealing section, the foaming agent is mixed and reacted, expanding to fit the shape of the product and forming a cushioning protective body.
Benefits of technology
Foam bags can fit perfectly with products of different shapes, improving protection and preventing displacement and damage during transportation.

Abstract
This utility model discloses a foam bag, including a first bag body and a second bag body. The first bag body has a first cavity, and the second bag body is disposed within the first cavity. The second bag body has a second cavity and a third cavity. The second cavity contains component A, and the third cavity contains component B. The second bag body has a first channel connecting the second cavity and the third cavity, and also has a second channel connecting either the second or third cavity to the first cavity. The first channel has a first sealing section that separates the second and third cavities, and the second channel has a second sealing section that separates either the second or third cavity from the first cavity. The sealing strength of the first sealing section is less than that of the second sealing section. With this structure, the foam bag can fully conform to products of different shapes, has strong versatility, and provides good fit, effectively protecting the packaged product.
