Stretch film is the often-overlooked backbone of many warehouses, in the UK.
Sure, boxes and tape get the most limelight; but if you want your parcels to stay well protected, stretch film and pallet wrap shouldn’t be forgotten. It’s thought that 150,000 tonnes of stretch wrap are used per year, so getting familiar with the product will only result in a positive.
In this blog, we will explore the benefits of using stretch film, along with the different types and application methods frequently used. We’ll cover common questions about recyclability and help you decide which stretch film would be best for your business.
What is stretch wrap?
Stretch wrap is a highly stretchable plastic film (typically made with polyethylene) wrapped around items. It’s also commonly called stretch film or pallet wrap.
Due to the film’s elasticity, it keeps items tightly bound, stopping them from moving about during storage and transit. One of the most common uses is to secure products on pallets.
Stretch wrap is available in different colours, lengths, and thicknesses. The thickness of the film is measured in a unit known as a micron, sometimes referred to as mu. Usually, the higher the micron, the stronger the stretch film.
KEY INFORMATION – Usually, the higher the micron, the stronger the stretch film.
The benefits of stretch wrap
There are many benefits to stretch wrap; some of these include:
- Prevent damage
- Helps with the safe moment of goods
- Minimising tampering
- Prevent loss
Like most packaging supplies, stretch film is used to protect products in storage and transit, arguably one of the most important areas for customer experience.
If their order arrives damaged, it affects consumer perception and costs your business. The impact (if frequent enough) could be significant to areas like administration and transportation.

Different types of stretch film
There are three main types of stretch film that you’ll come across:
Blown Stretch Film
Blown stretch films are made using a circular die that extrudes bubble of film. Additives are used to provide high cling, and good load stabilisation attributes.
Characteristics of Blown stretch films:
- Milkier or dull film appearance
- High cling on both sides of the film
- Excellent puncture resistance
- Bi-directional tear resistance
Cast Stretch Film
Cast stretch films are made using a flat die and can be produced with multiple layers. They have a smooth surface with excellent gloss, strength, and cling without additives.
Characteristics of cast stretch film:
- Clear and glossy film
- High transparency
- Film has cling on one side only
- Lower noise when being unwound
- Superior tear resistance
Pre-stretched film involves stretching the film during manufacture. This can help improve film strength, load stability and even the amount of film needed to wrap goods.
Characteristics of pre-stretch film:
- Good yield
- Very strong film
- Good for fast wrapping

Different types of application
There are two main ways stretch wrap can be applied, by hand or machine.
Hand application is when stretch film is manually applied by hand, which can be done with or without a hand dispenser. All hand-applied stretch films are supplied on standard cores for use with hand-applied applicators or extended cores.
Machine application is when stretch film is applied to a pallet or product using a pallet wrapper. A pallet wrapper is a machine that automatically winds film around a product. Machine-applied stretch films are extremely strong and versatile, which saves time, resources and packaging materials for high-performance applications requiring higher tensile strengths. These films have excellent puncture resistance and good cling, slip and load retention.
The possibilities are endless when it comes to stretch wrap; from different applications and types to varying strengths, you have so many great options.

Common questions about stretch wrap
Below we have listed some popular questions people have around stretch wrap. If you have any more queries that are not listed, our team of experts will be happy to help you.
Can stretch wrap be recycled?
Stretch wrap is made from low-density polyethylene (LDPE), which means it is a category 4 plastic material.
It can be recycled industrially but may not be collected at kerbside. Anyone looking to recycle stretch film locally should check with their local authority.
As it’s made from LDPE, you may be able to recycle it with supermarket carrier bag collections, however, it’s advisable to check services like Recycle Now or the collection points in your area.
Choosing the best stretch film for you
We recommend you measure your current usage and review your application before selecting a stretch film. The best way to calculate your usage is to look at your stretch yield in metres and your yield costs in weight. This enables you to calculate the effectiveness of your stretch wrap by calculating the cost to wrap a pallet.
