What Is The Purpose Of Shrink Wrapping? | Donglin Packaging

Shrink wrapping is a process of using a plastic film to tightly wrap a product or group of products. The film is then heated, which causes it to shrink and conform to the shape of the product. Shrink wrapping is a versatile and widely used packaging method, with a variety of purposes, including:

• Product protection: Shrink wrapping can help to protect products from damage during shipping, handling, and storage. The tight fit of the film helps to prevent products from shifting and bumping against each other, which can cause scratches, dents, and other damage.
• Moisture and dust protection: Shrink wrapping can also help to protect products from moisture and dust. This is especially important for products that are sensitive to moisture, such as food and electronics.
• Bundling products: Shrink wrapping can be used to bundle multiple products together. This can make it easier to ship and handle the products, and it can also help to reduce the risk of damage.
• Tamper evidence: Shrink wrapping can be used to create a tamper-evident seal. This means that it will be difficult to open the package without damaging the film, which can help to prevent theft and tampering.
• Shelf life extension: Shrink wrapping can help to extend the shelf life of products by protecting them from moisture, oxygen, and other factors that can cause spoilage.
