Whether wrapping pallets by hand or using a machine, each method has its own set of advantages and disadvantages that can influence not only operational efficiency but also environmental footprint.
Man(ual) vs. Machine
Manual wrapping offers cost-effectiveness and flexibility, making it an ideal choice for smaller operations. It doesn’t require expensive machinery or extensive training, and it saves space in the warehouse. However, it can be labour-intensive, inconsistent, and pose safety risks due to its manual nature.
On the other hand, machine wrapping offers consistent tension, enhanced efficiency, minimised physical strain on workers, significant cost savings and reduced plastic use. Although it requires substantial initial investment, maintenance expenses, additional space, and training, its benefits are substantial for high-volume operations.
Choosing the right method for your business involves weighing these pros and cons carefully, especially to reduce plastic waste and improve sustainability. This blog post will help you in your decision.
Wrapping pallets manually: understanding Conventional vs. Pre-stretched
When securing pallets manually, the choice between cast and blown pallet wrap can significantly impact efficiency and cost.

Conventional pallet wrap is made by feeding plastic resin through rollers to form a thin, clear film. This wrap allows for easy content identification and barcode scanning. It unwinds quietly and offers good tear resistance and cling properties, making it strong and reliable. Its high clarity ensures easy inspection of wrapped goods and it is cost-effective to produce. However, it requires more manual effort to stretch and is heavier, potentially increasing shipping costs.
Pre-stretched pallet wrap is stretched during manufacturing, and features a thin adhesive coating, making it easier to apply and reducing worker fatigue. It uses less material, providing high tension for consistent load stability. This wrap is lightweight, efficient, and environmentally friendly due to less waste. Although it is more expensive per roll and may have lower puncture resistance, it offers significant ease of use and material efficiency.
The Grip system and available films
The Grip pre-stretched pallet-wrapping system stands out as an exemplary solution revolutionising the industry. Featuring a brilliant Grip Applicator and high-quality Grip Film, this manual wrapping system significantly enhances load stability, material efficiency, speed, and productivity. It also offers ease of use, long-term cost savings, wrapping consistency, and improved worker safety. These exceptional benefits result in more efficient, reliable, and sustainable shipping operations.
Opaque and clear machine pallet-wrapping film
It’s important to consider a few things when trying to reduce plastic use and minimise costs for pallet-wrapping film, which is typically sold per kilogram. Finding the right balance between film thickness and yield is crucial for optimising your operations and reaching your sustainability objectives. One effective solution is to opt for a 17-micron PP clear film (unless an opaque solution is necessary). This type of film is lighter than the 23-micron film and has a 300% yield, allowing you to fully utilise the pre-stretching carriage system of your machine.
Another important factor when choosing film is the type of pallet that you are wrapping. Is it a square (A), irregular (B) or protruding (C) pallet? The table below will help you in your decision:

We can help you choose
Deciding on the right pallet-wrapping method can be challenging. While hand-wrapping may seem like a good starting point, machine-wrapping is the most efficient way to minimise plastic usage and reduce costs in the long term. The choice between the two methods depends on the type of goods, pallet, and shipping frequency.
