Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Example 1
The utility model discloses a barrier bag for a vacuum heat insulation plate, which comprises a barrier film 1, wherein the barrier bag is formed by compounding an outer protective layer, a polyester aluminized film layer, an aluminum foil layer and a heat sealing layer in sequence from outside to inside, the heat sealing layer is a PE film, the outer protective layer is a glass fiber film or a nylon film, the front and the tail of the barrier film 1 are connected together in a hot-melt mode to form a rectangular tubular structure, and a closing edge 10 is formed at the position of the front and the tail of the barrier film 1 connected together in a hot-melt mode. Each corner of the barrier film 1 with the rectangular tubular structure is provided with a corner crease 11, a center crease 12 is arranged between the two corner creases 11 on the same side, the barrier film 1 with the rectangular tubular structure is folded through the center crease 12 to form the barrier film 1 with the sheet structure, and one end of the sheet barrier film 1 is sealed by hot melting to form the barrier bag 100.
