Packaging sleeves can be made from various materials, depending on the specific application and desired characteristics. Here are some common materials used to make packaging sleeves

Paper or Cardstock
Paper sleeves are frequently made from paper or cardstock materials. They can vary in thickness and weight, depending on the intended purpose. Paper sleeves are lightweight, eco-friendly, and easily customizable. They can be printed with branding, product details, or designs.

Kraft Paper
Kraft paper is a type of paper that is produced from wood pulp, typically derived from the Kraft process. It is known for its strength and durability. Kraft paper sleeves are often used for packaging products that require sturdier protection, such as food items or heavy-duty retail products.

Cardboard
Cardboard is a thick, rigid paperboard material typically made from layers of paper or recycled fibers. It provides excellent structure and protection. Cardboard sleeves are commonly used for packaging items like books, DVDs, or electronics. They can be printed, laminated, or coated with various finishes to enhance their appearance and functionality.

Plastic-coated Paper
Some packaging sleeves are made by combining paper with a thin layer of plastic coating. The plastic coating enhances the sleeve's water resistance and durability, making it suitable for packaging items that may come into contact with moisture or require extra protection.

Specialty Materials

Depending on the specific requirements or desired aesthetics, packaging sleeves can be made from specialty materials such as textured paper, metallic sheets, fabric, or synthetic materials like polypropylene. These materials are often chosen to create unique and visually appealing packaging solutions.

It's important to note that the choice of material for packaging sleeves depends on factors such as the product being packaged, the desired level of protection, sustainability goals, and branding considerations. Therefore, different manufacturers and industries may use different materials for their packaging sleeves.
