Frequently Asked Questions

Q. What's the difference between CT & lug?

A. These are the two primary types of containers and closures currently used in food packaging. Continuous-thread (CT) is the Mason-style closure mechanism where the jar and lid are both threaded in one continuous bead around the entire circumference of the opening; also referred to as "screw-on". Lug is the closure system where the container has multiple threads and the lid has an equal number of lugs or tabs that grip the corresponding threads; also known as "twist-on".

Q. What is the best jar/lid combination for my product?

A. You have most of the answers to this question. What will you be putting in the jar? Will you hot-fill, water bath, or pressure cook your product? If you're water bathing your product, we suggest a retortable continuous-thread closure because there is less likelihood of over-tightening a continuous-thread, and retortable lids can withstand the higher heat of a boiling water bath (212 degrees F). Standard one-piece lids are manufactured for hot-fill temperatures (around 180 degrees F). Twist closures are manufactured primarily for compatibility with commercial machine capping equipment, but many of our customers twist them on by hand. After you determine what type of jar and lid combination will work best for your processing method, it's simply a matter of preference for appearance and price.

Q. Do you sell "Mason" jars?

A. Yes, but the real question is "what is a 'Mason' jar?". John Mason patented the continuous-thread closure on November 30, 1858. While most people use the term to refer to a home-canning jar, any jar with a continuous-thread closure can be called a Mason jar. Most of the jars we sell are smooth with no embossing, but we do carry a few sizes that have the word "Mason" embossed on the sides.

Q. Why glass?

A. The first concern for any food product marketer is the sustainable quality of the food inside. Nothing preserves freshness or displays the product better than glass. It is largely recycled and fully recyclable.

Q. What is your return policy?

A. We will gladly accept items returned in good condition within 30 days of purchase less a 15% restocking fee. Exchanges are not subject to re-stocking fee. Customer is responsible for shipping charges.
