BM5 (CS,CX) User’s Manual
Plastic document protectors, envelopes, or sheet separators made of polystyrene, polypropylene, or
polyethylene will not degrade thermal traces in themselves. However, these materials afford no
protection against fading from external causes.
Paper manufacturers advise us that these thermal products should retain their traces when properly
imaged and stored for about 3-5 years.
If your retention requirements exceed these guidelines, we recommend you consider
alternate image storage techniques.
