Kurita 20 Jan Testing is an essential part of the cleaning process and must be performed on a regular basis. The introduction of cyclic polyolefins COC0 by Ticona in Germany offers the pharma blister package yet another alternative. Final cleaning is performed under the most scrupulous conditions currently attainable in the contamination control field. Unfortunately, Nylon is hydroscopic which results in an affinity for moisture. But now we have found that some users actually show a preference for the 2 mil thick product. A razor blade should be avoided.
Unfortunately, ACLAR possesses one major undesirable trait in that it abrades and sloughs off plastic particles when rubbed or contacted by a packaged part. When subjected to high-energy radiation , it undergoes, like PTFE, degradation. It is similar to polytetrafluoroethene PTFE , except that it is a homopolymer of the monomer chlorotrifluoroethylene CTFE instead of tetrafluoroethene. This material has been selected by the majority of clean film users since it may be cleaned with solvents. The cost savings come from reducing lead times and shortening manufacturing cycles; eliminating the dependence upon a polymer market that is subject to volatility; and gaining the ability to develop, produce, and control all manufacturing in-house. Suwelack Skin and Health Care, Fa. ACLAR film has served to satisfy one need which other films as yet have not been able to provide, i. PCTFE is an addition homopolymer.
PCTFE finds majority of its application due to two main properties: The answer is yes, if you have access to a laminar flow unidirectional cleanroom that employs critical control of temperature, humidity and aerosol particles.
One drawback has been that cold forming produces large, shallow cavities requiring large blisters. Kurita 20 Jan At a minimum, this will meet the requirements of LP latest revision.
This accounts for PCTFE to have less flexibility of chain and hence higher glass transition temperature. All of the above developmental activity complements Lawson Mardon Singen’s outstanding success with its “Formpack” aluminum blister material.
The film is an all purpose film for parts proeprties require a moderate level of cleanliness in the packaging environment and are not particularly prone to puncture, abrasion prolerties cause sloughing of the barrier bag. Fluorinated Materials For Energy Conversion.
Clean Film Packaging – Newsletter
A razor blade should be avoided. PCTFE fiom used to protect sensitive electronic components because of its excellent electrical resistance and water repulsion. Long dominated by PVC, the bottom web market for pharmaceutical blister packs now is facing increased competition from a variety of new materials.
This material has been selected by the majority of clean film users since it may be cleaned with solvents. Cotton or woolen garments worn beneath the cleanroom uniform have a tendency to aid in transmitting lint and dust particles through the protective uniform into the clean environment.
The introduction of cyclic polyolefins COC0 by Ticona in Germany offers the pharma blister package yet another alternative. ACLAR 22A will soften in the presence of fllm solvents and therefore various film cleaning firms have been resistant to accept its use. It is similar to polytetrafluoroethene PTFEexcept that it is a homopolymer of the monomer chlorotrifluoroethylene CTFE instead of tetrafluoroethene.
Brydson 8 November Antistat agents used in the film are generally of no avail under these circumstances.
When the clean packaging film is to be cut, it is suggested that stainless steel scissors be used. Machinery used in the cleanroom must be designed to eliminate the addition of metal particles and similar contaminants while processing the plastic film.
ACLAR films should be used with great caution. It is generally known that no such film “miracle film” currently exists.
View Our E-Clips Archive. These specifications are by far the most complete and they provide the subcontractor in prime aerospace programs with an excellent set of detail guides in performing critical parts and systems packaging.
Lacquer expands utility of Aclar films
PCTFE is resistant to the attack by most chemicals and oxidizing agentsa property exhibited due to the presence of high fluorine content. It’s difficult to thermoform a machine can be modified and is used mainly by Bayer in Leverhusen, Germany, to package aspirin products.
Because of the poor crease resistance of ACLAR 33C, it is not suitable for center folding or pouch masking from center folded stock.
PCTFE films are used as a protective layer against moisture.
Don’t buy a cleanroom until you’ve read this publication. New Materials Society, Challenges and Opportunities: Other uses include flexible printed circuits and insulation propertiea wires and cables. Typically the nylon film used for clean packaging is 1. The optical properties and Propertids transparency is essentially the same. Unfortunately, the answer is no. Today, depending on specific requirements, there are many different types of plastic films that can be used.
The material offers an environmental alternative to PVC and has unlimited potential in the dynamic blister area. Low-molecular-weight PCTFE waxes, oils and greases find their application as inert sealants and lubricants.
