Gold metal 70-400 lid

with standard plastisol liner

The L028 is a gold metal 70-400 lid with standard plastisol liner. This lid is made of metal, which means it is fairly impervious to most processing methods. However, this metal lid has been fitted with a non-removable vinyl liner called plastisol, which has more restricted temperature and process requirements. When heated, and solidified, this plastisol liner creates an airtight, tamper-evident, hermetic seal. This cap is lined with standard plastisol, which is recommended for a "Hot Fill and Cool" heat process treatment. Minimum sealing temperature (temperature of the product in the jar after capping) is 185°F / 85°C, and the maximum process temperature tolerance is 185°F / 85°C. Please test your product.
