Can Metal Lug Caps Be Used for Pharmaceuticals and Nutritional Supplements?

Strict Requirements of the Pharmaceutical and Nutritional Supplement Industry

In the pharmaceutical and nutritional supplement industry, packaging is not only about appearance—it directly relates to product safety, shelf life, and consumer trust.

These products often contain high-value and sensitive ingredients, such as vitamins, dietary supplement liquids, and probiotic drinks. If the bottle cap does not provide sufficient sealing, it may lead to oxidation, moisture exposure, or even loss of effectiveness. This is why the industry often asks: Can metal lug caps meet such strict requirements?

Why Lug Caps Are Suitable for This Field

The answer is yes. Metal lug caps are already widely used in biotech foods and nutritional supplements, with the following main advantages:

• High Sealing Performance: Paired with PVC liners, they effectively block oxygen and moisture, ensuring ingredient stability and extending shelf life.
• Sterilization Resistance: Suitable for high-temperature retort sterilization or pasteurization, maintaining complete sealing even under conditions of 121°C for 30 minutes.
• Food-Grade Safety: The liner uses materials compliant with food safety standards, ensuring no harmful substances are released—meeting the high standards required for pharmaceuticals and health products.

Versatile Applications

• Pharmaceuticals: liquid medicines, reagent bottles
• Nutritional Supplements: vitamin drinks, probiotic beverages, herbal extracts
• Biotech Foods: dietary supplement liquids, health drinks
