Embodiment
Muffetee
Can utilize the present invention to produce identification tape, mark or label.Owing to the invention provides the ability of producing solid color image, therefore the means of the interim identification of replicate photos conduct quite easily with gray scale.For example, can produce the hospital's muffetee that comprises patient's photo.This will to hospital be provided at mother and child still in delivery room in, the muffetee that will have mother's photo is placed on neonate's ability on one's body.In addition, can read patient's record from the bar code of two dimension, described bar code can duplicate on the muffetee with the present invention's preparation.The present invention with laminar structure allow to select plastic foil more comfortable concerning dressing as basic unit, and part is because it is flexible and has due to the surface smoothness of delustring.It also provides good tear resistance and excellent pulling strengrth.Because it can adopt direct heat printer (or adopting the thermal transfer printer group of operating with the direct heat pattern) imaging of standard, the muffetee that therefore utilizes the present invention to prepare can easily be printed in the moment that obtains patient's permission.The anti-alcohol of the plastic foil of imaging, water and bear dirty.Other purposes of identification sign comprises the secret pass with the lamination of the user's who authorizes photo imaging.
The example that is suitable for use as the plastic foil of hospital's identification muffetee has following structure (referring to Fig. 1)
