What is Stretch Wrap?

Stretch wrap, also known as stretch film, is a highly stretchable plastic film commonly made from linear low-density polyethylene (LLDPE). When applied, it’s stretched around the item or load, and its elasticity keeps everything tightly bound together. This elasticity is a key characteristic of stretch wrap, and it’s what gives the material its name.

Stretch wrap is primarily used to wrap products on pallets and secure them for transportation or storage. It’s an essential tool in industries like warehousing, distribution, and logistics. The wrap’s elasticity allows it to hold items tightly together, reducing the risk of damage caused by items shifting or falling during transit.

One of the main benefits of stretch wrap is its versatility. It can be applied manually using a handheld dispenser for small-scale operations, or with a stretch wrap machine for larger volumes. It’s also available in a variety of thicknesses (gauges) and types, such as cast stretch wrap and blown stretch wrap, each with its own unique properties and applications. You can learn more about these in our article on cast vs. blown stretch wrap.

However, stretch wrap does have some limitations. While it’s excellent for bundling items together, it doesn’t provide a completely sealed cover, so it may not be the best choice for products that require airtight or waterproof protection. Additionally, while stretch wrap is generally resistant to punctures and tears, sharp edges or corners on packaged items can potentially cause damage to the wrap.

What is Shrink Wrap?

Shrink wrap, unlike stretch wrap, is a plastic film that shrinks when heat is applied, forming a tight, sealed cover around the product. It’s typically made from a type of polymer plastic film known as polyolefin. The process of applying heat, either through a handheld heat gun or a shrink tunnel, causes the film to contract, hence the term “shrink” wrap.

Shrink wrap is widely used in various industries for a range of applications. It’s commonly used to package individual products, such as CDs, books, or boxes of food, providing a tamper-proof seal that also enhances the product’s appearance. On a larger scale, shrink wrap can be used to protect boats, machinery, or large pallets of goods from dust, moisture, and UV rays.

One of the main advantages of shrink wrap is its ability to provide a completely sealed cover, offering excellent protection against external elements. This makes it a popular choice for products that need to be kept clean, dry, or secure. Shrink wrap also conforms closely to the shape of the product, which can be beneficial for irregularly shaped items.

However, shrink wrap does have some limitations. The need for heat application means that it’s not suitable for products that could be damaged by heat. Additionally, while shrink wrap provides a tight seal, it doesn’t have the same load securing strength as stretch wrap, making it less ideal for bundling large, heavy items together.

Key Differences Between Stretch Wrap and Shrink Wrap

While both stretch wrap and shrink wrap serve similar purposes in packaging and protection, they have distinct characteristics that make them suitable for different applications. Let’s explore these differences in more detail.

Materials Used

Stretch wrap is typically made from linear low-density polyethylene (LLDPE), which gives it its unique stretchable properties. This elasticity allows the wrap to be stretched around items, securing them tightly together.

On the other hand, shrink wrap is usually made from polyolefin plastic film. When heat is applied, this material contracts, forming a tight, sealed cover around the product.

Is Stretch Wrap the Same as Shrink Wrap?: Application Process

The application process for stretch wrap and shrink wrap is another key difference. Stretch wrap is applied by stretching the film around the items. This can be done manually with a handheld dispenser or with a stretch wrap machine for larger volumes.

Shrink wrap, however, requires heat to shrink and conform to the shape of the product. This can be done using a handheld heat gun for smaller items or a shrink tunnel for larger volumes.

Is Stretch Wrap the Same as Shrink Wrap?: Specific Uses

Stretch wrap is ideal for bundling items together, particularly for palletizing products for transportation or storage. Its elasticity and load securing strength make it a popular choice in industries like warehousing, distribution, and logistics.

Shrink wrap, with its ability to provide a completely sealed cover, is often used for packaging individual products, such as CDs, books, or food items. It’s also used for protecting larger items like boats or machinery from dust, moisture, and UV rays.
