Adhesive sleeves, also referred to as security sleeves, are a form of pliable packaging used to store and distribute optical media, specifically CDs and DVDs. They resemble a square envelope, accompanied with or without a fold-over flap and made with polypropylene plastic or vinyl plastic. The backs of the sleeves are equipped with an adhesive which is covered by a tape seal until desired use.
A standout feature of the adhesive CD/DVD sleeve is its tamper-resistant design. A security pouch anchors the CD or DVD and becomes evident of unwarranted use when the perforated seal is accessed. This design helps to ensure that discs cannot be easily removed.
