Abstract

The invention discloses a medicinal aluminum-plastic combined cover and a preparation technology thereof. According to the medicinal aluminum-plastic combined cover and the preparation technology thereof, after an aluminum sheet is cleaned, the surface of the aluminum sheet is coated with a silicon dioxide protection layer, on one hand, the aluminum sheet can be protected through the silicon dioxide protection layer, and therefore the situation that aluminum scraps adhere to the aluminum sheet and follow-up machining is affected is avoided; and on the other hand, after an aluminum piece is prepared, the aluminum piece is placed in a hydrofluoric acid and hydrochloric acid mixed solution to be etched, the aluminum scraps can fall off along with stripping of the silicon dioxide layer in the process, and the influence of the aluminum scraps can be reduced to a great extent. The technology is reasonable in design and easy to operate, the technical effects that the aluminum piece is super-hydrophobic and a plastic piece is super-obstructed are achieved by conducting surface treatment on the aluminum piece and the plastic piece, during actual medicine sealing, medicine pollution can be reduced, water resistance, moisture resistance and gas obstruction can be effectively achieved, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of aluminum-plastic composite caps, in particular to a medicinal aluminum-plastic composite cap and a preparation process thereof. Background technique [0002] With the development of the pharmaceutical industry, pharmaceutical companies have higher and higher requirements for pharmaceutical packaging, and the performance optimization of the aluminum-plastic composite cover has gradually replaced the aluminum-plastic composite cover of ordinary aluminum parts, becoming a more commonly used one in pharmaceutical packaging. Nowadays, oral liquid bottles, medicinal liquid bottles, infusion bottles, etc. are all made of glass bodies and sealed with aluminum-plastic composite caps, which have higher requirements for the waterproof, moisture-proof, and barrier properties of aluminum-plastic composite caps. [0003] At the same time, in the production process of aluminum-plastic composite caps, the existence of al...
