With the rise in the biogas industry, silage film is expected to get more traction in the coming years. Different industries are doing continuous research on the better deployment of advanced and efficient silage wrap films. The main intention for silage wrap in biomass is to retain moisture in the bales of biomass and regulate its water content.
Silage film is made of plastic film or a solid polymer. The plastic material can be one or more polyethylene terephthalate (PET) based and can be heat pressed or sprayed into the desired surface of the bales. The heat pressing method of laying down the material is a good way to make the silage film a strong layer above the soil.
The bales are placed in the crusher that spins at high speed. The hot air and the silage mix are then forced through the rollers, where it is released into the silage bags or rolls. After getting rid of the applied pressure, the bales are passed through the rollers, where they get re-wound and re-stretched into the desired shapes. After getting rid of the pressure, the bales get re-vibrated and folded once again into the desired shapes.
The silage is then extruded from the extruder head at high speed. The high-speed extrusion makes sure that the ball gets extruded and deposited in one piece. The dried pieces of the silage are then bundled together, and the dried mass is then taken to the manufacture. The entire process of manufacturing silage wrapping and drying is usually done in a large kiln room.
Low oxygen production is also an important factor when using bale silage wrap. It is because silage which is exposed to low oxygen for long periods, may develop cracks and blisters. Therefore, the manufacturing company would need to ensure adequate silage production. They may also want to incorporate special coatings and treatments to the raw material to improve its durability, resistance, strength, elasticity, and low oxygen sensitivity. These are essential in ensuring the quality of the silage wrap film and making it more effective and beneficial.
Silage wrapping is also a good way of recycling. By using silage film, the manufacturers can reduce their overall consumption of natural resources. The wrap polyethylene can resist degradation by chemical reactions and moisture, making it ideal for use as an agricultural product. It is also useful as a construction material since it has great tensile strength. Therefore, bale silage wrap plastic could prove to be a useful source of raw material for many industries.
