The difference between “sandwich folding” and “classic folding”
Foldable plastic large load carriers can save up to 80% of empty goods journeys, which leads to efficient and cost-optimized logistics.
Folding, however, is not equal to folding. There are big differences here. KTP attaches great importance to ergonomic and efficient handling. For this reason, KTP only offers folding systems where no additional locking is necessary. The container manufacturer offers its customers 2 different folding variants: sandwich folding and classic folding.
In sandwich folding, the ring is slip-resistant and protected in the empties between the lid and the pallet. Each empties unit is complete in itself. This enables quick and easy control (number of complete containers) and thus also an efficient individual allocation of empties to different locations. A stack of empties consists of 14 sandwiches (1 sandwich = pallet + lid + ring). The sandwich folding allows a return rate of 1:5, depending on the container size.
In the Classic folding, on the other hand, a stack of empties consists of 14 stacked pallets, 1 set-up ring with 13 inner rings and 14 lids on top. This also allows a very good return rate of 1:5. However, the empty allocation of individual containers is more difficult than for sandwich folding.
The System 2000 and System Quad product families are exclusively available with sandwich folding. With a few exceptions, the more cost-effective Classic and Export product families are offered with classic folding.
Sandwich folding: fast - efficient - ergonomic
up to 80% Volume Reduction in empties
In the case of sandwich folding, the ring is slip-resistant and protected between the lid and the pallet without any manual locking. The handling is easy and intuitive, which saves time. Sandwich-folded containers are the ideal solution for customers who often need to fold and transport their transport containers.
In the classic folding you have 4 or 5 (if a loose floor insert is used) pitches. A parking space for the pallets, one for the lids and one for the rings. In classic folding, the rings do not lie between the lid and the pallet, as in the case of sandwich folding, but are collected in a built-up container. A complete empty stack consists of 14 containers (14 pallets, 1 set-up ring with 13 rings inside and 14 lids on top).
