Interested in the 4 or glass low profile jars and the lids that are recommend for them. Are they food grade and lids are suitable for sealing? How many in a case?

SKU- 132990 comes in a case pack of 12 jars/case. This jar is made of glass that is food grade. We have three closure options (SKU- 302117, SKU- 302122, or SKU- 305548 ) that come with a plastisol liner. Plastisol is a common liner that is used for applications such as food canning and vacuum packing, because it provides a tamper evident and hermetic seal.
