We’ve reported on stretch film  and t-shirt bags in previous installments of this blog series, which provides snap shots of the results of 2017 research conducted by market-research firm Mastio & Co., St. Joseph, Mo. on the PE film industry. Here, we recap Mastio’s research on institutional can liners.

According to the Mastio research, approximately 1,556.1 million lb of PE resins were consumed by processors to produce institutional trash bags in 2017. With an average annual growth rate (AAGR) of 4.4%, Mastio projects this segment of the PE film business will increase to 1,782.3 million lb of PE resin consumption by 2020.

If you are a fan of fresh figs (as I am) then you may have resigned yourself (as I have) to the fact that when you buy figs in a plastic mesh-style box, the fruit on top may look great, but the figs on the bottom will be mashed, mis-shapen, and quite possibly moldy as a result.

Well, I am resigned to such disappointment no longer, thanks to a more imaginative use of plastics. For the first time since I have been living in New York City (which is all of my adult life), I found a supermarket that stocks fresh figs in thermoformed PET clamshells where each piece of fruit (six to eight) is held snugly in its own separate pocket. No bouncing around, no mashing, no squishing, no leaking of juice to promote mold growth.

There’s never a good time for a vacuum conveying pump to fail. Required for moving materials and resins, it’s an essential component to plastic processing and can shut down the entire operation when it fails. 

Those who can afford it resort to frequent monitoring with expert technicians, wasting time, effort and money. Moreover, this practice results in technicians blindsided by problems missed in-between maintenance scheduling.

Additive manufacturing (AM) and traditional injection molding can already check a lot of the same boxes: net-shape parts, precision, repeatability, a wide range of materials. The pace of change within AM is such that the technology is continuously making big strides in areas like resolution, speed and materials offered. Beyond the similarities with molding, there are also key differences, including geometries that would be virtually impossible in molding and the time and cost associated with the fabrication of tooling.

With that in mind, Molding 2018 (Feb. 27-March 1; Long Beach, Calif.) is providing an entire track dedicated to the technology—3D Printing: Molder’s Friend or Foe—which will feature a cross section of industry players who are fully immersed in additive manufacturing. Speakers in the session range from molders and moldmakers to printing technology suppliers and AM houses with the scale to challenge traditional molding in certain lot ranges.
