Stretch film, also known as stretch wrap or pallet wrap, is a thin, elastic plastic film primarily used to secure and protect goods during storage and transportation. It’s made from polyethylene and possesses unique properties that make it indispensable in the packaging industry.
How Does Stretch Film Work?
Stretch film's elasticity is its key feature. When stretched and wrapped around products or pallets, it creates a tight, cohesive bond. As the film retracts, it generates tension, securing the load and preventing items from shifting or damage.
Benefits of Using Stretch Film
- Protection: Shields products from dust, moisture, and physical damage.
- Security: Deters theft and tampering.
- Efficiency: Streamlines the packaging process and reduces labor costs.
- Cost-effective: Provides excellent protection at a reasonable price.
- Sustainability: Many stretch film options are available to meet eco-friendly requirements.
Stretch Film vs. Shrink Wrap: What's the Difference?
Stretch film and shrink wrap are both types of plastic film used for packaging, but they serve vastly different purposes. Let's break down the key differences between the two:
Stretch Film
- Purpose: Primarily used to secure and protect pallets of products during storage and transportation.
- Material: Typically made from polyethylene.
- Application: Wrapped around pallets to create a tight, cohesive bond that holds products in place.
- Key benefits: Protects products from damage, dust, and moisture; prevents theft; improves efficiency and reduces labor costs.
Shrink Wrap
When to Use Which
- Choose stretch wrap when you need to secure and protect large quantities of products on pallets for shipping or storage.
- Opt for shrink wrap when you want to individually package products for retail sale, food preservation, or bundling smaller items.
In summary, while both stretch film and shrink wrap offer protection, their applications and methods differ significantly. Understanding these differences will help you choose the right packaging solution for your specific needs.
