Tray & Shrink Packs
For many years, trays have been a popular alternative to RSC packaging. Trays can be used for both distribution and retail packaging, and they offer a significant amount of Source Reduction compared to traditional RSCs. Trays are helpful for keeping round products from shifting and shingling inside a pack and they can help prevent containers from chiming and cutting the film during palletizing. Trays are available in varying heights (from low wall to high wall) and they use less corrugated material and less glue than RSCs. Trays can be wrapped in bullseye / sleeve wrap, or in total closure shrink film for maximum protection.Packaging Mass Reduction
Let's examine a comparison between a printed RSC and the same contents wrapped in a low-height tray, wrapped in printed total closure shrink film.
Printed RSC: 276 grams
Corrugated Tray: 48 grams
Shrink Film, 1.5 Mil : 12 grams
The packaging mass reduction will be (276- 60) / 276 = 78%
Aside from the lower cost associated with less corrugate, the material cost savings are further impacted by the fact that an RSC is typically taped on both the top and the bottom to secure the flaps and seal the case.
