RSC Case OR Wrap Around Case? Selection criteria and automation options.
Why RSC (Regular Slotted Case): RSC stands for Regular Slotted Case, this is sometimes referred to as a knock-down case. It is the most common case style used to ship products. The box is shipped flat (knocked down) to the packager who sets up the box, fills it, and closes it for the shipment. Boxes can be closed by tape, adhesive, staples, strapping, etc. RSC Cases are popular because they use optimal material to completely encapsulate the product. They can also be easily erected by hand from a folded state because the manufacturer’s flap is already sealed in the proper location. There are multiple machines and automation options in the market to automate this style of case packing. If you want to learn the basics about various case packing automation options, then you should read this article first. Why Wrap Around Case: A wraparound case is basically a flat piece of corrugated board that can be formed and sealed around the product. Most of the time, the wraparound blank is partially formed to allow for product to be loaded into it from the side. The end flaps and manufacturers flap are then closed and sealed with glue. This is typically done using automatic equipment. Although a wrap-around case will resemble an RSC once fully erected and sealed, there are some unique benefits over an RSC case. Food, Beverage and FMCG manufacturers are continually looking for the ways to reduce the cost of their products and improve productivity. Material cost is always one of the closely followed metric, which includes the corrugated case that is used for shipment of product to their customers. Changes to case style is something that is often considered for cost savings. Changing from an RSC design to a wraparound design is fairly common. A wrap-around case can save the manufacturers quite a bit of money because of the following advantages. Wrap Around Case benefits over RSC cases: Wraparound Cases support Right-Sized Packaging, Since the corrugated blank is made to fit the dimensions of the product, waste is minimized. Not only is this good for any overall bottom line, it's good for the environment too. With wraparound technology, if the box / case has a low profile (which is common), the flaps will be on the smallest sides, there is usually substantial savings on the board for the board manufacturer. There is an additional cost for the material supplier to form and seal the manufacturers flap on an RSC case. In WAP blank no glue is to be used by the converter and one of their manufacturing process is eliminated, so the savings can usually be passed to the customer. The quality / aesthetics (squareness) of a finished case is affected by the quality of the pre-glued joint on an RSC case. The quality of a finished wraparound case is more consistent due to all flaps being formed and sealed using automated packaging equipment. As a thumb rule, converters usually offer about 10% reduced price on wrap around cases blanks v/s RSC case. Logistics cost savings: Less RSC case blanks fit on a pallet compared to wraparound cases. More blanks on pallet means less freight costs, there is possibility to have about 20-60% more blanks on each pallet in case of wraparound blanks v/s RSC cases. On an average 10-30% freight costs can be saved for the corrugated board supply and expensive floor space in manufacturing facility can be better utilized. The magazine of Wraparond Case Packer machine can hold about double the blanks v/s RSC Case Packer magazine. Using wraparound cases result in less intervention by operator to replenish blanks on an automated machine. This usually means less fatigue to the operator and hopefully less OH&S concerns. While there is a common perception that RSC cases have greater stacking strength when palletized, a wraparound case can have just as much stack strength if designed correctly. Wrap around case packing can reach far higher speed than automatic packing in RSC cases. Well, on few occasions and in few industries, the norm is to use RSC cases and WAP cases don’t work well for some applications. One of the major reasons for continuing using the RSC cases is intertia associated with changing to a new case style. When any organization starts their products manufacturing, case packing is usually manual and therefore RSC cases are used as that is the most convenient way to pack products manually in boxes. As the manufacturers business grow, they still want to keep using whatever is working and many times stick with RSC cases and automate the operation using the optimal solution. Although, if the manufacturers are prepared to consider all the options and do due diligence for wrap around and RSC case style, they will most likely lean towards Wrap Around solutions.
