Custom boxes are made from different materials. Each element determines the strength of the box and its use. Depending on the depth of one's pocket and the purpose of acquiring a certain container, one can specify what material they want their boxes to be made of. However, it would be wise to do a quick research before getting on the phone (or laptop) to order a custom container.
Custom Box Materials
Corrugated Plastic: Also known as Corriboard, corrugated plastic is a wide-range of plastic-plastic-sheet products made from high-impact polypropylene resin. Lightweight but tough, this material is mainly used for making signs and containers (read: boxes). Boxes made of corrugated plastic come in different sizes are reusable, and carry heavier weights than paperboard boxes. Corrugated plastic has many trade names, including Coroplast, Correct, and Twinplast, and it also comes in many colors.
Corrugated Fiberboard: This is the brown material most boxes are made of. Corrugated fiberboard is a type of paperboard that is made up of three layers: two flat pieces of paper with a fluted (corrugated) layer in the middle. This layering gives the material its strength, as well as the boxes.
Paperboard: Paperboard is a thick material made of, yes, paper. The main difference between cardboard and paper is that the former is thicker than the latter. Paperboard has several types, depending on their use and the industry using them, such as kraft board, laminated board, et cetera. A kind of paperboard is what is used to make corrugated fiberboard.
Cardboard: This refers to any heavy-duty paper. As such, most people use the terms cardboard, paperboard, and corrugated fiberboard interchangeably. Technically they are not the same thing. Cardboard is the parent name for all other 'boards.'
Wood: A hard material gotten from trees, wood is used to make crates and boxes and cases. It would be nice if one decided not to use wooden crates, as this would help the afforestation movement, and make steps towards reducing global warming.
Plastic: light, durable material produced by chemical processes, it can be formed into different shapes when heated. Mostly used in making crates, the plastic containers are divided into compartments that hold bottles for transportation and storage.
Metal: Metal containers are made of iron, tin, gold, or other alloys like brass. Boxes made of metal are durable, though susceptible to rust, and very expensive.
These are the different types of materials that are used to make custom containers. The strength, durability, and cost of a custom box depends on the material a customer chooses, and one's choice matters greatly if they are getting custom boxes for delivering goods to their clients.
Getting goods from A to B is hard enough. Finding the right way to carry those goods is another headache. Once, we loaded and unloaded goods item by item - those were the days when labour was cheap. Then the Second World War came. This mother of many inventions brought us the wooden pallet. This, combined with a fork lift truck, enabled goods to be moved quickly and with less labour.
The wooden pallet was a great idea. So good was the idea that it is still going strong to this day. However, things have changed. Pallet pooling can be an expensive business. Rental and purchase costs have risen to reflect the increase in timber costs and the extra burden of fumigation and quality control.
Escalating fuel costs have taken their toll on the inevitable dedicated trips that are made to repatriate empty pallets when imbalances occur in the supply chain. These fuel costs - and driver shortages - have also forced an examination of the space and weight taken up by the ubiquitous pallet.
The pallet is a bit like the air that we breathe. It is all around us yet we don't see it. It is easy to forget the extra cost that the pallet adds to the value chain. Perhaps now the time has come when, in some eyes, the pallet has outstayed its welcome. Rather than being the carrier, is the pallet itself being carried by the value chain? Rather than wait for another world war, a ready solution has been found and is tried and tested. That is the Slip Sheet.
Enter the Slip Sheet
Slip sheets have been around for some time, especially in the
U.S. where the free market has always had the knack of taking the path of least resistance. European countries tend to prefer centrally planned systems and standardization. Slip sheets lack firmly agreed international standards and this may be one of the reasons why they have not been popular in Europe. The greatest reason is ignorance. Many simply have no understanding of slip sheets and how they work - so they don't bother.
So perhaps it's time to right this wrong here and now.
How Slip Sheets Work
1. Slip sheets are durable sheets of material that are designed to carry a uniform load of goods with plan dimensions (or "footprint") of roughly 1 metre square/40 inches square (typically they may be designed to carry a footprint of 40 inches x 48 inches - 1m x 1.2m). The slip sheet is made to these dimensions plus a pull tab - an extension to the sheet - of up to 6 inches/15cm. There may be just one pull tab sticking out from under the load on one side. There could, however be pull tabs on 2, 3 or all 4 sides. Slip sheets can be made of
fibreboard or plastic.
2. Goods are loaded directly onto the slip sheet within the creases that border any pull tabs. A push-pull attachment on a forklift truck is used to drag the load onto the truck by gripping (one of) the pull tab(s). The push-pull attachment has very flat ground-level forks that are designed to go under the
slip sheet whilst it is under load
3. To unload, the forklift truck pushes the load, complete with slip sheet off of itself and withdraws
Pros and Cons
Slip sheets are not the panacea to all distribution needs. For one thing, all parties in any supply chain will need to invest in the push-pull attachments, which are not cheap. The staff training that will be required, especially for forklift truck operators, can also be expensive. Perhaps the greatest factor, though, is the uniformity of the load itself. This exposes the slip sheet's greatest advantage - and greatest disadvantage. Slip sheets may not be able to cope when boxes are awkwardly shaped or where there is a mixed load of different shapes. Conversely, if a company is shipping out large quantities of the same sized box, then slip sheets are ideal. As such, slip sheets lend themselves to operations further upstream of the supply chain. As loads are broken down further downstream, then pallets may be more appropriate. The good thing is that loads of slip sheets can be easily transferred to pallets. A good example of the advantages of using slip sheets is where parts for goods are manufactured and shipped through a long distance sea route. The space and weight saving can result in a significant financial boost for the value chain.
Co-operative Value Chains
Another great factor in all this is uniformity of slip sheet systems. All parties in the supply chain need to be using the same specification of slip sheet and ensure that all staff are fully trained to ensure delivered loads are configured correctly for the receiving party. This requires value chains that are highly co-operative, or, to be realistic, it requires a value chain that has one dominant party who will simply dictate their requirements. The U.S. has pioneered slip sheets and has used them for many years. However, the dominance of the supermarket sector in some European countries may be forcing the change there also. The ability of large supermarkets to influence their supply chains means that they are in a position to take a strategic view of the benefits that slip sheets can bring. They are in a position to arrange for both senders and receivers to be ready to handle products on slip sheets. Things are changing. Perhaps the pallet industry is about to get a jolt.
Watch this space. There are tremendous savings to be made and significant environmental benefits to be gained. Full conversion to slip sheets for any supply chain is not going to happen, but a partial conversion for particular product lines is not only desirable, but inevitable - even in Europe.
