Vacuum packaging is often associated with the consumable food industry. Thousands of different food products are vacuum packaged daily around the world to preserve and extend the shelf life of products.
Vacuum sealers are also often used for many industrial products as well. Many different industrial products are vacuum packaged for different reasons.
In this video we are vacuum sealing PVC fittings that contain an inner metal washer. During overseas shipments the washers rust from salt water during transport. Vacuum packaging the products eliminate oxygen exposure to the metal washers preventing rust.
The AVN vacuum sealer used in the video is capable of sealing over 300 products per hour. A variety of widths are available depending on the product size and bag required.

Specifications grading is a system of student assessment described by Linda Nilson in her newest book, “Specifications Grading: Restoring Rigor, Motivating Students, and Saving Faculty Time”. In specs grading, assessments are aligned with learning outcomes and implemented using bundles of assignments that are graded pass/fail, and students choose the grade they wish to attain and select the bundles accordingly. For more background, see the links at the end of this post.
In this hangout, +Theron Hitchman of the University of Northern Iowa and I will be talking specs grading and its potential use in university mathematics courses. TJ and I just finished reading the book and so we are not experts in this — the discussion is for hammering out thoughts and airing out ideas. Hope to see you there.
In case it’s not clear, the hangout is on Thursday, December 4 at 3pm Eastern.
