Sam Lan’s Cap Liners and Seals: Where Quality Always Comes First

Primary packaging is the first layer of packaging that directly contacts the product. It serves multiple purposes:

✅ Protection – Shields products from moisture, air, and contaminants.
✅ Preservation – Maintains freshness and extends shelf life.
✅ Branding – Enhances product presentation and consumer appeal.
✅ Convenience – Ensures easy use, storage, and transportation.

Compared to secondary and tertiary packaging, which focus on grouping and transporting products, primary packaging is what consumers interact with daily. From plastic bottles to glass jars and tin cans, the right material ensures product safety and quality.

Glass is a premium choice for packaging because it is non-reactive and keeps food, beverages, and pharmaceuticals fresh. It also provides excellent protection against contaminants.

Many glass bottles and jars feature bottle cap liners, which prevent leaks and contamination. This type of seal liner create an airtight seal, ensuring longer shelf life.
