AI Technical Summary
Existing insulated packaging bags have a short-lived insulation effect and are prone to tipping over, making it difficult to maintain temperature and stand stably for extended periods.
A release film is glued to the inner wall of the insulated bag, and a cardboard board is glued to the release film. The cardboard board has grooves in which heating pads are placed. The stability is improved by flipping the cardboard board, and the heating pads provide continuous heating.
It achieves long-lasting heat preservation and prevents tipping, improving the standing stability of the insulated bag and lowering its center of gravity.
