A Guide To Pre-Stretched Film

In the packaging world, pre-stretched film has emerged as a game-changer for industries seeking efficient, cost-effective, and secure packaging solutions. With its unique properties and advantages, pre-stretched film has gained widespread recognition across various sectors. But, what exactly is pre-stretched film? How is it made, and what sets it apart from traditional packaging materials?

What Is Pre-Stretched Film?

Pre-stretched film is a specialised type of packaging material which is used across many industries to secure and stabilise loads on pallets during transportation or storage. Unlike traditional stretch wrap, which requires manual stretching during the application, pre-stretched film is manufactured with an inherent stretch and it is wound onto rolls, reducing the effort needed during wrapping. Despite being much thinner than traditional stretch wrap, it contains similar strength parameters, meaning it weighs less - approximately ⅔ less - but is just as durable.

Pre-stretched film is beneficial in industries such as:

• Manufacturing: Securing raw materials and finished goods on pallets for distribution.
• Retail: Packaging products for display and distribution in retail shops and supermarkets.
• Logistics and Warehousing: Stabilising pallet loads for safe transportation and storage within warehouses and distribution centres.
• Food and Beverage: Ensuring the safe transit of perishable goods and preventing contamination during shipping.

How Is Pre-Stretched Film Made

The manufacturing process of pre-stretched film involves carefully stretching the film to a predetermined percentage of its original length before winding it onto rolls. This stretching process aligns and orients the molecules within the film, enhancing its tensile strength, puncture resistance, and load-holding capabilities. The film is stretched using specialised equipment that ensures consistent tension across the entire width of the film.

What Are the Advantages of Pre-Stretched Film?

Pre-stretched film offers a range of benefits to those who use it, especially when compared to traditional stretch-wrapping solutions and it is, therefore, no surprise that more businesses are looking to utilise this type of high-performance film. So, what are the most important advantages this film brings?

Increased Efficiency

Pre-stretched film requires less physical exertion during application compared to traditional stretch film, resulting in faster and more efficient packaging processes. Users can wrap pallets more quickly and with less effort, increasing productivity and streamlining operations.

Eliminating Neck Down

When heat is applied to traditional stretch film it begins to soften and conform to the shape of the item being wrapped. This is known as “necking down”. As the film shrinks, it tends to gather more tightly around the edges or corners of the object, causing the width of the film to decrease in those areas. Pre-stretched film eliminates necking down, achieving a tightly wrapped finish.

Cost-Savings

Overall, pre-stretched film offers a cost-effective packaging solution for businesses, often saving up to 40% in costs. The inherent stretch of pre-stretched film means less film is required to secure each pallet load, resulting in lower material costs. Additionally, a reduction in labour time translates to savings in manpower expenses.

Enhanced Load Stability

The consistent tension and superior cling properties of pre-stretched film ensure that pallet loads are tightly secured, minimising the risk of shifting or damage during the transit of goods. This enhanced stability reduces the likelihood of product loss or returns due to damaged items, benefitting both ends of the supply chain.

Versatility

Pre-stretched film is suitable for a wide range of applications and load types, including irregularly shaped or heavy loads. Its adaptability makes it a versatile packaging solution for diverse industries such as manufacturing, logistics, food and beverage, and retail, leading to more unusual-shaped items being protected whilst in transit.

Environmental Benefits

Some varieties of pre-stretched film are manufactured using eco-friendly materials and processes, making them a sustainable packaging option. Additionally, reduced material usage and improved efficiency contribute to lower carbon emissions. Alongside reduced material usage, there is typically a reduction in wasted film, since the film is pre-stretched for the desired size.
