Level 3 Orange PE Security Film
This is our standard design Level 3 orange security bag sealing film with void message & temperature indication & water soluble ink features.
When the tamper evident seal film is applied on bag, the pre-designed white line will turn red when heated and the printing text “water” will vanish when it comes into contact with a liquid, such as water or solvent. Meanwhile, the tape film reveals a hidden message such as“VOID OEPN” on lift tape and transferred onto the security bag upon removal. These changes are permanent and irreversible, reminding the recipient unauthorized access has occurred.
