Priority Plastics brings new technology for large PET containers to the US

Priority Plastics, a blow molder for storage and customer-specific HDPE, PET and PVC containers, is expanding beyond extrusion blow molding into the PET injection stretch blow molding (ISBM) process. The company plans to install several machines this month that are reportedly the first in the U.S. to use new single-stage ISBM technology that will make PET containers from 1-gallon handle to 25-gallon kegs can. The machines will go to the main plant in Portland, Indiana. (The company also has plants in Arizona, Iowa, and Colorado.)

Super-wide neck PET containers are a capability of the new ISBM technology being introduced by Priority Plastics in the United States.

Priority Plastics declined to name the foreign source of these machines, but claims they offer several benefits that are new to the US PET market. For example, you can make jugs with an integrated handle, similar to strand-blown HDPE jugs, but without any trimmings.

With the new ISBM technology from Priority Plastics, stretch-blown PET containers can be produced in a manner comparable to extrusion-blown cans.

Another type of handle - injection molding as part of the neck finish - is also possible with the new PET ISBM technology installed by Priority Plastics.

Other capabilities reportedly include stackable bottles, rectangles, and wider necks than are available from competing ISBM technologies. Other advantages mentioned are quick changeover times and energy savings of up to 40% through the recovery of high-pressure blow air for use in extrusion blow molding processes.
