For polybag packed merchandise always use Micro-Pak® PE Sheets instead of stickers to avoid potential discoloration issues.

Micro-Pak® Stickers are placed in the box at the time of final packing. When humidity is high the moisture in the air enters the sticker and starts a reaction that creates a Micro-Pak® atmosphere. This Micro-Pak® atmosphere spreads throughout the package to eliminate mold spores.

Silica gel and other desiccants are designed to absorb moisture and while some of these may be quite effective at this they are not specifically going after mold spores. Micro-Pak® products will both absorb moisture and create and release an atmosphere to eliminate mold spores.

  1. Open the foil package, remove the roll of Micro-Pak® Stickers and place it in the dispenser box.
  2. At time of final packing tear off one or more pieces of Micro-Pak® Stickers and stick them on the inside of the box base for best results.
  3. The box should be closed immediately after putting the stickers on the box base and not reopened.
  4. Any unfinished rolls of Micro-Pak® Stickers should be placed back in the foil package and closed with tape for use within the next day.

Please also see Instructions for Use on our website for further details.

The number of Micro-Pak® Stickers to be used depends on the size of the box and the humidity level. In most cases one piece of Micro-Pak® Stickers will be sufficient. Please refer to the Instructions for Use on our website and your customer’s instructions for further details.

Keeping items free from mold involves a number of steps and to avoid mold problems we recommend that factories take certain measures including the following:

  1. All materials must be stored properly and in dry conditions.
  2. Factories should be kept clean.
  3. Wet items or boxes should not be packed.
  4. Avoid storing goods for long periods especially during the rainy season.
  5. Items that have been stored in the factory warehouse should be checked again prior to shipment.
  6. Factory warehouses should be dry with good ventilation.
  7. Attend the Micro-Pak® seminars and workshops on mold prevention.

The Micro-Pak technical team can provide further advice on mold prevention procedures.

If the foil bag is not opened you can store Micro-Pak® Stickers for up to one year from date of production. Once the bag is opened the stickers should be used as quickly as possible. Any unfinished quantities should be placed back in the bag and used ideally within the next day.

Micro-Pak® Stickers should be stored in dry conditions and out of direct sunlight.

Micro-Pak® Stickers will reduce or eliminate mold continually for extended periods depending on humidity levels. Third party lab tests show continued activity for more than five months.

Micro-Pak® Stickers will still work but the effectiveness will be reduced depending on how long you store your products and how high the humidity is.

When you reopen the box you are letting the Micro-Pak® atmosphere escape and may be letting in more moist air. Since you have compromised the atmosphere it would be best to replace the sticker.

Micro-Pak® Stickers can only stop the continuous growing of the visible mold but cannot make visible mold on products disappear. For cleaning visibly moldy product you should consider using Sporicidin Cleaning and Disinfecting Solutions.

Many of these chemical sprays are unsafe for workers, consumers and the environment and may also be in violation of various national and international regulations. Micro-Pak® products are EPA registered in the US, REACH
pre-registered in the EU and in process of being registered under the BPR.

Micro-Pak® Stickers can be ordered from Micro-Pak Ltd. in Hong Kong or via our authorized distributors as per our website.

Micro-Pak® Stickers comply with the restricted substance policies of major retailers and brands through the world. Micro-Pak® Stickers have also undergone stringent safety testing as part of our registration with the US Environmental Protection Agency (EPA).

The final use of the Micro-Pak® Stickers is in the hands of the factory and as we cannot control how they are used, the condition of the factory or the condition of the product when packed we cannot guarantee that you will not have a mold problem. In case you do face any mold problems please contact our Technical Services Department for assistance.
