Inner sleeves are protective coverings used to hold and safeguard vinyl records. Typically made from paper or plastic, they fit inside the outer jacket of the record, preventing dust, scratches, and other damage. Inner sleeves can also help reduce static electricity, which can affect sound quality. These sleeves come in various materials, including polyethylene and paper, each offering different levels of protection. Some inner sleeves are designed with anti-static properties, while others may feature a soft lining to cushion the record. Proper use of inner sleeves is essential for maintaining the longevity of vinyl records.
