Regulatory Information on Packaging and Shipment

 • Handling – As capsules are very susceptible to outside temperature and humidity, they should be kept away from heat sources and other environmental extremes to keep capsules from being heat damaged, deformed and sticky.

 • The following conditions should be kept to maintain shelf-life of capsules:

   1. Ideal Storage Conditions : The packed corrugated boxes should be stored on pallets in a well protected area at a temperature between 15 – 250 C and relative humidity between 35 – 65%.

   2. Heat sources, e.g. radiator or sunlight through windows should be avoided, as localized heating and moisture migration within the capsules may be caused.

   3. Storage under or near sources of water, such as condensation on pipes and / or leaking valves should be avoided.

 • Capsules should not be subjected to sudden temperature fluctuations and if stored in unheated warehouses, should be allowed to equilibrate with the conditions in the filling area before use.

 • The corrugated boxes should be re-sealed if, Quality Control samples are removed from the box.

Packaging & Storage

This is yet another Critical & Very Important stage, unless the packaging and storage conditions doesn’t meet the requirements, the whole process is of no importance.This last stage of the journey begins with the initial packaging of defect free capsules in non-static polyethylene bags of 100 micron thickness to hold sufficient quantity of capsules based on capsule size.

A 30 mm EPS blocks are placed on all 6 sides of the corrugated box to prevent damage of capsules due to moisture penetration and / or excessive heat radiation.

 • Domestic Supply : Our Capsules are packed in heavy wall 7 ply virgin Kraft paper corrugated boxes. We supply one size corrugated box for all size of capsules for Domestic supply.

 • Export Supply : Export supplies are made by AIR or SEA. In this case the capsules are packed initially in plastic laminated aluminum bags with EPS blocks as escorts to prevent damage to the capsules from moisture and heat. The final corrugated boxes are again wrapped with polyethylene sheet to prevent damage.

 • Outer Dimensions : For Domestic Supply : 670 x 480 x 680 mm For Export Supply : 670 x 480 x 730 mm
