Packaging is an essential part a very important part of the shipping process and is done to protect the product from being damaged during transport, handling and storage. We have varieties of packaging options.
In addition, we have built the capability to individually tube, individually collar, paper wrap the materials, use a wooden box or any combination of these options depending upon our customer's preferences.
We pack all our products in high density polythene sheets to protect their flawless surface during transportation and distribution. The products are first wrapped by signode wrapping, packed in thin plastic sheets and thereafter packed in high density polythene sheets thus providing double protection to the product. Large sizes product is packed in bundles. For small quantity, the material is packed in wooden boxes and then packed in high density polythene sheets so as to maintain the products.
Besides the above standard packing, we also provide materials in following packing as per the specific needs of the customer:-
casing of each product in plastic foil (popularly known as Tube Packing) and then such material wrapped together in high density polythene sheets bundles.
Two strong materials lifting straps are wrapped around bundles so that unloading of the bundles is easy from box containers.
