Bottle Inserts
Bottle inserts (also called sealing liners or inner plugs) are precision-molded plastic components placed inside caps to ensure leak-proof, tamper-resistant, and airtight sealing. They are widely used in chemical, pharmaceutical, FMCG, and food packaging. These inserts prevent spillage, contamination, and maintain product freshness by providing an extra sealing barrier between the bottle and the cap.
