Stretch film, also known as stretch wrap or pallet wrap, is one of the most popular unitization materials on the market. Unitization is a process of bundling and securing several individual packages together, often on a pallet. This is done manually or using high-speed wrapping machines for better quality & speed.
The following outlines the benefits of stretch film over other unitization techniques.
- Less damage to product versus strapping
- Virtually eliminates load crushing by distributing the force of the film over the entire load, without the use of corner boards
- Can take a shock or vibration and still maintain the load in its original unitized configuration
- Material cost per pallet is less than shrink wrapping or strapping
- Equipment is less expensive than shrink wrapping, bagging or automatic strapping equipment
- Provides lower operating and maintenance costs
- Provides a large energy saving over shrink wrapping
- May be produced tinted or opaque for product identification or pilferage prevention
