What is Vented induction foil seals?

Ideal for bottles containing gas-releasing products(e.g., fermented foods,agro-chemicals) or those exposed to significant altitude changes during transport, this liner prevents leaks, bulging, and seal failure while maintaining freshness and product integrity.

Q: How to measure bottle neck diameter for induction seals?
A: To ensure a perfect fit for your induction liner, follow these steps to measure your bottle's diameter accurately: 1. Measure The Bottle Opening (Inner Diameter - ID) Use a caliper or ruler to measure the outside edge of the bottle's mouth (including the screw ). Record the millimeter (mm) measurement. 2. Measure The Cap's Inner Diameter (Sealing Surface Diameter - SSD) If using a screw cap, measure the inner sealing surface without screw (where the liner contacts the cap). This ensures the liner aligns correctly when sealed. Or we can measure the correct size according to the bottle samples you provide.
