Delkor Spot-Pak I and P series

Delkor is the inventor of the patented Spot-Pak packaging system. This system attaches product to corrugate pads with temporary glue and then shrink wraps the package. This packaging style is a sturdy and sustainable replacement for RSC cases. The Spot-Pak Package is one of the most sustainable packaging solutions in the market today; it saves our customers 50-80% in material costs when compared to typical corrugated board cases.

The Spot-Pak package was originally developed by Delkor to optimize secondary packaging for tapered containers typically used for yogurt, cottage cheese, and sour cream. Today, more than 50% of the entire North American production of cultured dairy products goes to market in a Spot-Pak package.

Experience has also shown that the Spot-Pak system can be adapted for a wide variety of rigid containers – metal cans, blow-molded bottles, tapered cups, glass or plastic jars, paperboard cartons and canisters – making it suitable for a broad range of applications, with new applications emerging on a continuous basis.
