Bulk 70mm Metal Mason Jar Lids – Tinplate Lids in Golden/White/Black with Plastic Liner

These premium 70mm metal mason jar lids combine aesthetic appeal with functional performance for professional food preservation. Crafted from food-safe tinplate, the lids feature a durable plastic liner that creates a reliable airtight seal, ensuring long-term food freshness and safety. Available in three versatile colors—golden, white, and black—these lids offer both visual consistency and branding opportunities for commercial packaging.

The standardized 70mm threading ensures compatibility with most regular mouth mason jars, while the corrosion-resistant tinplate construction maintains integrity through repeated use and cleaning. The heat-resistant plastic liner withstands canning processes without compromising seal quality, making these lids suitable for both hot-fill and cold-storage applications.
