When you need an efficient way of packaging your raw materials, like hay, grain or silage, a biodegradable bale wrap is undoubtedly an excellent solution. Biodegradable packaging materials are widely available and have been in use for quite some time now. This is because the packaging of these raw materials plays a very important role in keeping the products intact and safe throughout the delivery process. The researchers also developed a bale wrap for silage. They developed a bale wrap, which consists of a single thin layer of woven paper.
The bale wrap is made from two layers only. The first layer comprises a thin 1-inch thick layer of uncured silica gel, which is applied on top of the unbroken honeycomb material to be wrapped around the bales. This layer acts as a protective shield against moisture and keeps the hay or grain clean and dry during transportation. The second layer of the bale wrap for silage is made up of a highly permeable membrane. This membrane allows the free-flowing water to penetrate the bales without being trapped thereby preserving the integrity of the raw material.
Utilizing this type of wrapping in organic silage film also saves a lot of cost in maintaining the health of the bales. The bales need not be packed every time they are needed because they do not spoil easily. Also, it reduces the load on the packaging equipment and containers, which in turn makes the packaging procedure much more efficient and faster. This also enables manufacturers and exporters to save on labour costs and other costs associated with the handling and packing raw materials. This is because they do not need to employ people to do the job. Instead, the material can be handled very simply by using the bale wrap technology.
The baled material for wrapping is mostly sourced from Australia, where its availability is quite good due to the lack of climatic conditions that affect the availability of man-made fibre. However, due to its high cost, manufacturers from other countries such as the United States, South Africa, and New Zealand are increasingly using bales made of man-made fibre in place of natural fibre. While these bales are generally thicker, they tend to be less flexible because of their manufacturing process. Therefore, bales that are to be used in the making of silage bags are often subjected to considerable stretching before they reach the stage of being wrapped.
The wrapping bales in organic silage film are made from two different kinds of fibres. One is polyethylene, while the other is nylon. The latter is preferred for the reason that it is easier to handle, flexible and stronger. Polyethylene bales are preferred because they have a long-life span and are also capable of resisting chemicals that are present in the ingredients of the finished product.
Baling material is most commonly white. It has been found out that wrapping bales increase the air permeability of the same. Thus, silage manufacturing industries can be run more efficiently due to this feature. They also help in retaining heat. Other features of bales that make them ideal for wrapping are their ability to withstand very high temperatures and maintain their shape during manufacturing.
