5. The process for producing an aluminum foil medicine packaging composite bag capable of preventing delamination under high temperature and high humidity environment according to claim 1, comprising the steps of:
s1, when a medicine compound bag (1) is produced, firstly, after an upper compound film (101) and a lower compound film (102) are subjected to hot-pressing sealing, the edges of the upper compound film (101) and the lower compound film (102) are folded, so that edge sealing openings of the upper compound film (101) and the lower compound film (102) are pressed at the center position of the width after being folded, at the moment, a clamping block (201) at the top end of the upper compound film (101) and an embedded block (202) at the bottom end of the lower compound film (102) are pressed after being placed, so that a clamping sinking block (2024) of the embedded block (202) is clamped into a limit groove (2014) of the clamping block (201), and meanwhile, as the edge sealing openings of the medicine compound bag (1) are pressed between the clamping block (201) and the embedded block (202), and the edge sealing openings are positioned close to the clamping sinking block (2024), a half-arc protruding block (2) and a half-arc protruding block (2012) are compacted, and a small-arc protruding block (2023) and the clamping block (2024) are compacted, so that production is completed;
s2, in the actual use process, as the semi-arc bulge block (2022) is compacted with the semi-arc large groove (2012) and the small-arc bulge block (2023) is compacted with the clamping sinking block (2024), the clamping block (201) and the embedding block (202) are influenced by the external high temperature and high humidity environment, so that the clamping sinking block (2024) is clamped into the limit groove (2014) more tightly, water entering between the clamping block (201) and the embedding block (202) is suddenly reduced, little water can permeate into the semi-arc large groove (2012) from a gap between the semi-arc bulge block (2022) and the semi-arc large groove (2012), or when the semi-arc large groove (2012) is upward, the large-arc design of the semi-arc large groove (2012) and the semi-arc bulge block (2022) makes the water extremely difficult to permeate, and when the clamping sinking block (2024) is positioned at the small-arc bulge block (2023) and the small-arc groove (2013), the water is difficult to enter into the upper composite film (101) and the lower composite film (101) is prevented from being extremely wet, and the situation of sealing the composite film (1) is avoided;
s3, under the condition of high temperature, the hot melt adhesive of the upper layer composite film (101) and the lower layer composite film (102) can be easily softened to cause the upper layer composite film (101) and the lower layer composite film (102) to be layered, and as the conical ventilation grooves (2011) formed in the clamping blocks (201) and the conical ventilation holes (2021) formed in the embedding blocks (202) can cause the outside hot air to enter the conical ventilation holes (2021) and the half-arc protruding blocks (2022), the outside hot air can enter the conical ventilation holes (2021) and the half-arc protruding blocks (2022) due to the design of the conical ventilation holes (2021) and the half-arc protruding blocks (2022), and when the outside air enters the large circular openings of the large circular openings, the air can be caused to enter the small circular openings of the conical ventilation holes (2021) and the half-arc protruding blocks (2022), the temperature of the temperature ventilation grooves (2025) can be reduced, so that the temperature of each air groove (2026) can be easily coordinated between the grooves (2025) to cause the temperature of the upper layer composite film (101) and the lower layer composite film (102) to be not layered, and the lower layer composite film (101) can be compounded.
