Frequently Asked Questions
Q: What are foam cap liner seals and how do tamper-evident cap seals work?
A: Foam cap liner seals are soft, compressible discs placed inside bottle or jar caps to create an airtight, leak-proof seal. Tamper-evident versions bond to the rim of the container upon first opening, so any attempt to open the bottle leaves a visible mark — giving consumers confidence that the product is intact and untouched.
Q: What size cap liner or foil seal do I need for my bottles?
A: The seal size should match the inner diameter of your bottle or jar's neck opening. Our foam cap liner seals range from 20mm to 101mm, and our aluminum foil sealing stickers range from 9mm to 38mm, covering most standard cosmetic, perfume, and supplement containers. Measure the inner diameter of your cap or bottle neck before ordering.
Q: Are these caps and seals suitable for cosmetic and perfume packaging?
A: Yes! Our foam induction seals, self-adhesive cap liners, and aluminum foil stickers are widely used for cosmetic jars, perfume bottles, essential oil containers, and lotion bottles. They help preserve product integrity, prevent evaporation, and maintain freshness over time.
Q: Can I use these sealing stickers and liners without special machinery?
A: Absolutely. Our self-adhesive foam cap liners and aluminum foil sealing stickers are designed for manual application — simply peel, place, and press. No heat-induction equipment is required for the self-adhesive varieties, making them ideal for small-batch producers and home crafters.
Q: What is the difference between PS foam cap seals and self-adhesive foam cap liner seals?
A: PS (polystyrene) foam cap seals are insert-style liners that sit inside the cap and create a seal when the cap is tightened. Self-adhesive foam cap liner seals have a pre-applied adhesive backing, allowing them to be stuck directly to the rim of the container before capping, providing an additional bond for extra tamper-evidence and leak protection.
