TRANSPARENT PLASTIC CONTAINER FOR ANTICOUNTERFEIT SYSTEM |
摘要 |
<p>A transparent plastic container which is transparent, allows good design and can housed for an anticounterfeit system that determines authenticity by visual check with the use of polarization property. A transparent plastic sheet of a polystyrene-based resin having a total light transmission of 85% or higher and a haze of 7% or less is subjected to vacuum, pneumatic or vacuum/pneumatic forming at a sheet temperature ranging from a glass transition temperature plus 50 degrees C. to a glass transition temperature plus 130 degrees C., thereby obtaining a transparent plastic container having a planar portion with a strain amount of 150 nm or less.</p> |
