Designed for applications that require a large amount of granules and moisture protection.

They are often used in the following applications:

  1. When it is not possible to place a sachet in each box. The covers can be placed on top of the pallets and quickly removed at the destination, if necessary.


  1. As a supplement for the container filters. Only two filters can be placed in the air intake of the container evaporator. If increased autonomy or a lower balance of ethylene emitted and eliminated is required, these covers are an ideal solution.


  1. Long-term preservation. Can be used for the long-term preservation of apples, pears, and other high-emission products. Our technical services, based on the duration of storage, the type of atmosphere (AC, ULO, Dynamic), weight per pallet or bin, type of fruit, etc., will design the perfect-sized cover for each application. Even distribution throughout the container, for example, one cover for every pallet or bin, is based on centralized filtration and is a major improvement over past solutions. The cost is extremely competitive compared to treatment with 1-MCP.
