Plastic Jar Lid - PP5
Regular Mouth - 70 mm

This plastic jar lid will fit all regular mouth (70 mm) canning jars. The lid is made of a thick autoclavable PP5 polypropylene plastic that is of much better quality than typical plastic lids. These lids will form an airtight and watertight seal when screwed firmly on the jar.

Impressed with the strength of the lid, I broke one but that was due to my lack of drilling technique. It broke pretty gracefully though and didn’t shatter. Pretty resistant to heat and moisture.

These lids are very high quality... not your standard Ball lids... much better, as they are not adversely affected by sterilizing.
