AI Technical Summary
Traditional sewn bags have multiple small holes at the seal, which affects the airtightness and results in poor moisture and dust protection.
A guiding structure is used to guide the deformation of the packaging bag sealing part, cover the hemp thread insertion part, and combine with heat sealing to enhance the sealing strength and reduce contact with outside air.
It improves the sealing and moisture-proof performance of the seal, extends the shelf life of the contents, and maintains the ease of installation and removal of the sewn bag.
