It has the following drawbacks: the three sides of the barrier film are sealed by heat sealing to form the barrier bag, so that the production steps and heat sealing equipment are increased, and the material preparation speed of raw materials of the vacuum heat insulation plate is greatly reduced; due to the flexible property of the barrier film, the core material needs to be manually loaded by a worker, so that the core material loading rate is low; and the core material is vacuumized after being bagged, so that the core material can be vacuumized only by completely pumping air in the barrier film bag, and the efficiency of the vacuum treatment of the core material is reduced. The above defects all affect the production speed of the vacuum insulation panel, and further reduce the production efficiency of the vacuum insulation panel.
