Product Information

About this item

• AIRTIGHT TAMPER-EVIDENT FOIL SEAL: Aluminum foil cap liners bond to the bottle mouth under induction heat to form an airtight, leak-proof, tamper-evident seal that locks in freshness and shows when a container has been opened
• MATCH TO GLASS BOTTLES AND JARS: These liners are made for glass containers with non-metal caps; induction sealing needs the liner to match your container, so use glass liners on glass bottles and jars for a proper seal
• REQUIRES AN INDUCTION SEALER: Set a liner in the cap, close the bottle, and pass it under an induction sealing machine that heats the foil to bond it to the rim; a sealer is needed and not included, and sealing works only with non-metal caps
• MOISTURE AND OXYGEN BARRIER: The aluminum foil layer blocks moisture, oxygen, and leaks to help extend shelf life and keep contents fresh; a common choice for airtight packaging of liquids, powders, and pastes
• 100-PIECE PACK, 70 MM: Each pack holds 100 liners sized 70 mm for non-metal caps with a 70 mm inner diameter; suited to food, beverage, cosmetic, and general airtight packaging, so measure your cap to confirm the 70 mm fit
