What is the difference between Shrink Wrap and shrink sleeve?

Shrink wrap and shrink sleeves are both packaging materials used for enclosing and protecting products, but they differ in their composition, application method, and typical uses.

Composition:

Shrink wrap: Shrink wrap is typically made of polymer plastic film, such as polyolefin or PVC (polyvinyl chloride). It's available in various thicknesses and can be clear or printed with graphics.
Shrink sleeve: Shrink sleeves are made from a thicker, more flexible plastic material like PETG (polyethylene terephthalate glycol). They are usually printed with high-quality graphics and text.

Application Method:

Shrink wrap: Shrink wrap is applied by wrapping it around the product or pallet and then heat is applied to shrink the film tightly around the item.

Shrink sleeve: Shrink sleeves are pre-printed and then applied to products using a labeling machine or a heat tunnel. The sleeves are heated, causing them to conform tightly to the shape of the product.

Uses:

Shrink wrap: Shrink wrap is commonly used for bundling items together, such as packs of water bottles, CDs, or boxes of software. It's also used for protecting larger items during shipping and storage.
Shrink sleeve: Shrink sleeves are often used for labeling bottles, jars, and containers in industries like food and beverage, cosmetics, and pharmaceuticals. They provide a 360-degree branding opportunity and tamper-evident seals.

In summary, while both shrink wrap and shrink sleeves provide protective packaging, shrink wrap is more versatile for wrapping various items, while shrink sleeves are specifically designed for labeling cylindrical or uniquely shaped products.
