What is wrapping?
Film wrapping is a technique where a thin plastic film is wrapped around a pallet or product. This can be done manually or mechanically. Various terms are used, such as wrapping, stretch wrapping and pallet wrapping, but they all mean the same thing. Wrapping allows products to be bundled, secured and/or protected against, for example, falling over, damage and dirt during transport and storage. The ultimate goal is to wrap products well, undamaged and at the lowest (total) cost in order to send them from A to B.
Why film wrapping?
Film wrapping is a relatively inexpensive and easy-to-apply method of securing load. It is suitable for both uniform and irregular loads. Other advantages of film wrapping are:
- A solid, complete and inexpensive packaging
- Protection against dirt & damage
- Suitable for “fragile” products
- Very suitable for holding products together
- Flexible: the tension and amount of film can be adjusted
- For a wide range of products: from boxes to doors
- By wrapping with a coloured film, the product is recognisable or not in order to prevent theft
How does it work?
Several layers of thin plastic film are wrapped around the load or a product by hand or with the aid of a pallet wrapper. In this way, stabilisation and protection is ensured. There are various types of pallet wrapper: the turntable, arm, ring and robot wrapper and the horizontal wrapper. Each type of wrapper has its own specific characteristics.
What is a good wrapping?
A good wrapping means that the film is as tight as possible around the load, without damaging the product. In addition, the stability is good, the load is connected to, for example, a pallet, there is no “film end”, it looks neat and presentable and all this, at the lowest possible cost per pallet/load.
This result is achieved by carefully adjusting different elements:
- What is the load?
- What is the right pre-stretch?
- What film tension is required?
- What wrapping pattern?
- What type of attachment to the pallet is required?
What is pre-stretch?
Pre-stretch is a term often used in film wrapping. Pre-stretch means that the wrapping film is stretched; 1 metre of film is then used to “make more film”. The purpose of pre-stretching is to save wrapping film and increase the stability of the load.
The amount of pre-stretch is given as a percentage, ranging from 0% to 400%.
- 0% pre-stretch – 1 metre of film remains 1 metre of film
- 200% pre-stretch – 1 metre of film becomes 3 metres of film
- 300% pre-stretch – 1 metre of film becomes 4 metres of film
By using the right pre-stretch, the savings can be as much as 80%.
Outgrown manual wrapping? Take the next step!
Matco International has several pallet wrapping machines in their range. When producers have outgrown manual wrapping, the next step can be chosen: semi-automatic or fully automatic pallet wrapping, when you no longer want to have to worry about it at all.
Semi-automatic pallet wrapping machines
From a few pallets per hour, the capacity becomes too high for manual wrapping. Semi-automatic pallet machines offer a solution. These machines achieve a capacity of 20-25 pallets per hour. Because the wrapping cycle is fully automated, each load has the same wrapping pattern. In addition, these pallet wrapping machines have a pre-stretch system. The pre-stretch system stretches the wrapping film to the desired pre-stretch percentage.
Fully automatic pallet wrapping machines
With fully automatic pallet wrapping machines, loads are wrapped fully automatically without the intervention of an operator. Now and then, operators only need to replace a film roll. These pallet wrapping machines have several wrapping programs that can be set. The different loads can be processed interchangeably; the pallet wrapping machine selects the right programme for the right load. In this way, the pallet wrapping machine automatically adapts to different loads. The capacities range up to 150 pallets/hour.
Thanks to our many years of experience, expert knowledge and good cooperation with customers, we offer optimum security in final wrapping systems for every sector. Matco distinguishes themselves with a contemporary vision and approach: we use our broad knowledge and experience to proactively find innovative solutions for complex transport packaging. Through acquisitions, network expansion, service expansion and range expansion, Matco is able to meet any demand from any customer.
