An 48mm black plastic lid which fits both plastic and aluminium jars with an 48mm neck. The jar lid comes complete with a liner to improve the seal and to ensure that your product does not come into direct contact with the lid.
If you require any help in determining whether this is the correct cap for your jar / bottle, then please do contact us. All bottles and jars we sell contain a complete description of their neck type and therefore simply selecting the same neck type from the closures will ensure you have the correct neck.
In the above example you can see the pipette has slightly raised, this means that the seal has been properly created in the cap and the cap has now made an airtight seal inside, ensuring that the contents do not leak and air doesn't contaminate your product.
