What are Harvest Guard Reusable Canning Lids made from?

Harvest Guard Reusable Plastic Canning Lids are manufactured using an FDA and USDA approved, food grade plastic generally referred to as Polyoxymethylene Copolymer (POM) or Acetal Copolymer.  It is comprised of a BPA and Phthlate free plastic compound that is safe for direct contact with food products and has been used extensively in the food and medical industries since the 1940’s, provided users do not exceed the limitations listed below.

This product is formulated using polyacetal base resin and complies with applicable FDA regulations for food contact applications according to (CFR), Title 21, 177.2470.  Any additives, that may be present, comply with appropriate, specific FDA Regulations.

Limitations:

  1. Types of food: Acetal Copolymer is safe with all types of food except those containing 15% or more alcohol.
  2. Not recommended for tinctures where alcohol content exceeds 15%.
  3. Conditions of Use: Use temperature not to exceed 250 deg F per 177.2470.

Additionally, Acetal Copolymer plastic is approved by the USDA for direct contact use with meat and poultry products, and meets the Sanitary Standards 3A Compliance for the Dairy and Food Industries Supply Association (DFISA).

Considering the temperature ranges found in the home food canning environment, and the acceptability of POM by the USDA and FDA for direct food contact, we believe this is the perfect product for home canners.  An investment in Harvest Guard Reusable Canning Lids today, means a lifetime of safe, enjoyable canning, and a lifetime of savings.

Tips and Hints For Proper Use of Harvest Guard Reusable Canning Lids 

Tips and Hints For Proper Use of Harvest Guard Reusable Canning Lids 

  • Always wash and thoroughly clean lids and rings prior to use. Harvest Guard Reusable Canning Lids and Rings are dishwasher safe.  Never clean lids with bleach of other oxidizing agents or strong acids.
  • Read instructions before use and always follow proper USDA recommended canning practices. Improper use can cause seal failure and possible injury due to hot temperatures of canned food products.
  • Use standard mason jar metal band when processing. Overtightening of metal bands can cause seal failures due to trapped pressure in the jar.
  • Never tighten metal bands on jars with lids that appear convex or “domed”. This is indicative of trapped pressure in the jar which can release and cause severe burns or injury.
  • Always exercise extreme caution when removing hot jars from pressure canner or water bath as injury can result. When tightening metal bands after processing, cover jars with a kitchen towel to prevent accidental contact with hot jars or contents.
  • Allow canned products to cool for 12-24 hours at room temperature before removing metal bands. During cooling period, ensure jars are not directly under air conditioning vents as this may affect proper cooling and sealing of lids.
  • After jars are cool to the touch, remove metal band and gently lift upward on plastic lid to ensure proper seal. Failed seals will lift without any resistance.  If a failure occurs, re-process according to USDA approved methods, or consume un-sealed products immediately.
