How to produce high-quality aluminum-plastic combination covers

1. Workshop environment

Medical sealed aluminum-plastic lids are an integral part of packaging of medicines. The quality of the aluminum-plastic lids directly affects the quality of the medicines. If the aluminum-plastic caps are produced in an unclean workshop environment, it will definitely affect the quality of the packaged drugs. Therefore, the cleanliness of workshops that manufacture pharmaceutical aluminum plastic covers must meet the requirements of pharmaceutical factory workshops. Dust prevention measures must be taken. The inspection and packaging workshop must be equipped with air purification devices and must be operated in a sterile environment to achieve a level that does not require cleaning and disinfection when used in pharmaceutical factories.

2. Production equipment

Vulcanization uses a vacuum degassing flat vulcanizing machine or an injection pressure vacuum flat vulcanizing machine. In this way, the remaining air in the mold cavity and the volatile gas in the rubber material can be removed without adding water. The future direction is that semi-finished products tend to use vacuum extrusion preforming machines, vulcanization uses group control injection vulcanization units and thick-edged porous molds, high-temperature short-time vulcanization, and microcomputer control of production.

3. Surface treatment and cleaning

In order to prevent low-volatile components and organic substances from precipitating on the surface of the aluminum plastic cover, the surface of the formed aluminum plastic cover must be treated with silicone. Treated aluminum-plastic caps can also improve operation on automatic dispensing machines. The aluminum plastic cover must be cleaned and disinfected after edge flushing, and the water required for cleaning is relatively high. Use distilled water, or at least water that has been treated with a microporous filter membrane with a pore size of 0.65 microns.
