Abstract
Claims
1. A biodegradable continuous slip chain zipper bag roll structure, comprising: A roll body is formed by connecting multiple bags end to end; each bag includes a layer of biodegradable material. A guide tear structure is provided between adjacent bag bodies, and the guide tear structure is located at the junction of adjacent bag bodies; each bag body has a sliding chain sealing structure at its open end; the sliding chain sealing structure includes a first sliding chain track, a second sliding chain track, and a sliding member that can move along the first sliding chain track and the second sliding chain track; the first sliding chain track and the second sliding chain track are respectively fixed on both sides of the bag opening; the sliding member is located on the outside of the first sliding chain track and the second sliding chain track; a bottom seal is formed at the lower end of each bag body.
2. The biodegradable continuous slip chain bag roll structure as described in claim 1, wherein the guide tear structure includes at least one tear guide line.
3. The biodegradable continuous slip chain bag roll structure as described in claim 1, the slip chain sealing structure comprising a first slip chain track, a second slip chain track and a slider, wherein the slider has a guide groove.
4. The biodegradable continuous slip chain bag roll structure as described in claim 1, wherein the guide tear structure is located at a predetermined distance below the slip chain sealing structure, so that the bag retains the complete slip chain sealing structure after tearing.
5. The biodegradable continuous slip chain zipper bag roll structure as described in claim 1, wherein the biodegradable material layer is PLA, a bio-based polymer, or a composite thereof.
6. The biodegradable continuous slip chain zipper bag roll structure as described in claim 1, wherein the bag roll system is formed by continuously winding a plurality of bags into a roll shape, with a hollow core formed at the center of the winding.
