Quality » Manufacturing


MJ Plastic has no choice but to offer the highest levels of quality. Our customers demand it. Their products – pharmaceuticals, foods and beverages, nutritional supplements, consumer chemicals and personal care products – demand the most stringent requirements of any packaging.

Prototyping & Production:

Once your new mold has been completed, we schedule either a production or a test run, depending on the type of mold and the platform it runs on. Once the samples are approved we will complete the production tooling and schedule an initial production run. At this time, the bottles will again be evaluated and put through our thorough PCAP process. One key advantage of the many platforms we offer: we match production needs to the right equipment, achieving the ideal in quality and economics.


We use only raw materials approved by the Food & Drug Administration. The quality of our resins also ensures successful package. We insist on using only resins that will consistently perform as promised, documented by proven Batch Quality Assurance Certification. As with any of our stock components, Alpha can provide certificates of compliance on raw materials and finished goods. We also maintain a Drug Master File for the convenience of our customers.
