The Science Behind Superior Sealing Performance<\/h2>\n\n\n\n<p>The sealing integrity of an aluminum-plastic cap stems from its dual-layer architecture:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Aluminum Layer (Barrier Function):<\/strong><br>Typically 0.5\u20130.6 mm thick, the aluminum shell provides exceptional resistance against oxygen, moisture, and light \u2014 three major factors that degrade sensitive drugs like vaccines, antibiotics, and biologics. With a density of ~31.568 kg\/m\u00b3, aluminum offers high strength-to-weight ratio, ensuring durability without adding bulk.<\/li>\n\n\n\n<li><strong>Plastic Liner (Sealing &amp; Flexibility):<\/strong><br>Made from medical-grade PP or PE, the inner liner is formed via stamping and bonding processes to ensure perfect conformity with bottle necks (e.g., 20mm caps fit vials with 69.30mm height \u00d7 56.38mm diameter). This eliminates micro-leaks and ensures tamper-evident security after first use.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u2705 <strong>\u0645\u0639\u064a\u0627\u0631 \u0627\u0644\u0635\u0646\u0627\u0639\u0629:<\/strong> According to USP &lt;670&gt; and EP 3.2.2, primary packaging must maintain seal integrity under stress conditions including temperature cycling, vibration, and drop tests.
