SAN DIEGO - In a market expansion, Poly Pak America Inc. of Los Angeles is supplying liquid-proof Rigur polyethylene shipping envelopes designed specifically for pharmaceuticals. Two labs began using different sizes of the custom-imprinted envelopes in May and September, respectively. Kansas City, Mo., distributor Data Source supplies Osborn Laboratories of Shawnee Mission, Kan.
Los Alamitos, Calif., distributor Duramark Inc. supplies Pharmchem Laboratories Inc. of Menlo Park, Calif.
``The post office has accepted the envelope for the mailing of pharmaceuticals directly to an end user and for the mailing body-fluid samples to a laboratory for testing,'' Ian Young, Eastern regional sales manager, said at Interphex West, held Oct. 8-10 in San Diego.
Two pharmaceutical companies are looking at a similar application, and Poly Pak will begin making the bag for Metropolitan Life Insurance Co. next month.
In 1985, using a mixture of high and low density polyethylene, Poly Pak President Richard Gurewitz created the material Rigur for use in making strong, puncture-resistant, waterproof envelopes.
The multilayered olefin provides a structure for security and opaqueness.
Poly Pak employs 150, generates annual sales of more than $25 million and occupies 70,000 square feet of manufacturing and 50,000 square foot of shipping warehouse facilities.
