Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag structures of heating packs, in particular to a packaging bag structure of a heating pack. Background Art

[0002] The packaging bag structure of the heating pack is usually a bag-like structure made of plastic film or composite material. Its function is to wrap the heating pack and protect its internal chemical substances from the influence of the external environment. At the same time, it has the functions of heat insulation, waterproofness and sealing to ensure that the heating pack can continue to release heat during use.

[0003] The packaging bag structure of some current heating packs is usually simple in design. After people open the packaging bag and take out the heating pack, the packaging bag cannot be used to store the used heating pack for a second time. Therefore, during the process of garbage stacking and recycling, the heating pack is prone to damage and leakage, causing environmental pollution.

[0004] Therefore, we have made improvements to this and proposed a packaging bag structure for the heating pack. Utility Model Content
