Sleeves are a straightforward, cost-effective form of packaging that consists of a thin envelope, often employed for the budget distribution of CDs or DVDs. This article explores the historical context, types, key events, detailed explanations, and much more.
Historical Context
The concept of sleeves originated in the mid-20th century when vinyl records became popular. Simple paper or cardboard sleeves were used to protect these records. As technology evolved and CDs and DVDs became prevalent in the 1980s and 1990s, sleeves adapted to these new formats.
Types of Sleeves

- Plastic Sleeves: Offer better protection against moisture and physical damage.
- Cardboard Sleeves: Provide more rigidity and can include printed graphics and information.
- Poly-lined Sleeves: Combine paper and plastic to offer durability and disc protection.
Key Events in Sleeve Usage
- 1982: The first commercial compact disc (CD) is released, leading to the need for appropriate packaging solutions like sleeves.
- 1996: DVD technology is introduced, further popularizing the use of sleeves for distribution.
