Sales packaging

The initial use was as a blow moulded vessel for vegetable oil candles. However, because of its biodegradability it is of interest for applications where paper and plastics materials are used together and which can, after use, be sent into a standard paper recycling process. Instances include blister packaging (the compound is transparent up to 3 mm in thickness), envelopes with transparent windows and clothes point-of-sale packaging. 

As far as practicable and appropriate, the information needed to use the device safely must be set out on the device itself and/or on the packaging for each unit or, where appropriate, on the sales packaging. If individual packaging of each imit is not practicable, the information must be set out in the leaflet supphed with one or more devices. Instructions for use must be included in the packaging for every device. By way of exception, no such instructions for use are needed for devices in Class I or Ila if they can be used safely without any such instructions. 

The integrity of the design and construction of each source and sales package was demonstrated by subjecting active sources to tests simulating expected adverse service conditions as specified in "Tests for Special Form Materials" (1). These tests include ... 

In addition to all of the above tests, quality assurance tests during encapsulation demonstrate the integrity of each 252cf sales package and neutron source. 

Welding Control. Plugs in the inner and outer capsules for the sales packages and industrial sources are seal-welded with an argon-shielded or helium-shielded tungsten electrode DC arc. The capsule is rotated under the automatically controlled arc to produce a minimum weld penetration of 1.27 mm. Each weld bead is visually inspected by periscope or by Questar telescope, and imperfectly formed welds are rejected. Weld quality is controlled by periodic metallographic examination of dummy capsules welded in the in-cell equipment. 

Capsule closures for medical sources and seeds are made with an argon-shielded plasma DC arc. The arc is controlled to produce a weld bead penetration equal to, or greater than, the capsule wall thickness. Each weld bead is visually inspected by a 20X stereoscopic microscope or by Questar telescope. Weld quality is controlled in the same manner as with sales packages and industrial sources. 

Leak Testing. Sealed capsules of sales packages and industrial sources are pressurized in 300 psi helium for 20 minutes. Leak tests are performed on individual capsules in a helium leak detector whose lower limit of detection is 1.0 x 10 8 standard cubic centimeters of helium per second. All capsules must show no detectable leak. 

Labeling. Sales packages are identified by engraved designations which are numbered serially (SR-Cf-1001, SR-Cf-1002, etc.). Industrial sources are also numbered serially in the -100 series (SR-Cf-101, SR-Cf-102, etc.). Each package and source is provided with an information sheet listing pertinent construction, test, and calibration data. 

Medical sources and seeds are not identified by engraving so as not to lessen the integrity of the 0.015 mm wall. Successive groups of sources made for each contractor are identified by uniquely positioned gold bands, or other color coding as requested by the user to accommodate handling procedures. Information sheets are furnished as with sales packages and industrial sources. 

Vertex business is divided into six categories Technical Components, Dairy, Industrial Containers, Household Products, Food Trays and Securefresh. Processes include rigid blow-moulded containers for industrial, household, chemical and agricultural products extruded sheet and thermoformed containers for food manufacturers, kiwifruit and horticultural products disposable and point-of-sale packaging for the food service sector and injection-moulded components for human and animal health products.
