What to Look For in a Silage Film

The best silage film will have a high-slip layer, preventing bale damage during stapling or storage. The film will also contain a UV master batch, which protects the bales from sunlight. These two qualities are critical to the film’s overall performance. The film is available in various materials, including polyethylene and polypropylene. However, the most suitable film for your needs depends on your farming operations.

The Global Polyethylene Silage Film report provides a comprehensive analysis of the market for this product, covering the growth prospects, challenges, key drivers, and opportunities. The report also focuses on the competitive landscape, identifying the key players and the latest investment opportunities. In addition, it provides information on recent developments, including new product launches and industry trends.

The polyethylene-based film is a good choice for silage production. It is available in a variety of compositions. For example, the film can be polyethylene (60-90%) or low-density polyethylene (LDPE). Alternatively, a film may include a dicyclopentadiene hydrocarbon resin at a concentration of between three and twenty per cent.

Oxygen barrier

The oxygen barrier in silage film is a valuable tool for silage processing. Its high oxygen barrier and mechanical properties make it a valuable product for reducing spoilage in silage. In addition, it can help save feed for livestock. It can be applied as a top cover or underlay.

The film is usually a multilayer structure consisting of two outer layers and a core layer. Typically, the core layer is about 40-60% of the overall thickness. Its outer layers are between 15 and 35 microns thick. These layers are made of different materials. For example, the core layer can be polyethylene or ethylene-vinyl alcohol.

The material used for silage film is usually polyethylene. It is an extremely lightweight but strong film. It has unique oxygen barrier properties and is over 100 times more effective than conventional silage sheeting. However, it must be protected against sunlight and water to make it even more effective. Therefore, it is essential to use UV covers or goalkeeper gravel bags in conjunction with the film.


The cling of silage film is the layer of sticky material outside the roll. The cling level of the film should be between five and ten N/m. This film is cast with PIB, either in liquid or granule form. The casting process is straightforward and requires very little skill.

The cling of silage film can be improved with the use of high-oxygen barrier film. This film is 1.6 mils thick and provides excellent air barrier properties. It can be combined with a UV net and weighting to provide maximum protection. It clings to the top of the silage clamp similarly to conventional “cling film” sheets but doesn’t need a second layer of black plastic to prevent moisture from penetrating the film.

Polytechs has been producing cling masterbatch for more than 30 years. Polytechs offers three grades of cling masterbatch to meet the needs of customers. It is highly consistent in quality and provides support for all the processes. To develop a superior cling masterbatch, the Polytechs team first identified the parameters that influence migration and how they impact the quality.


The biodegradability of silage film is an essential issue as hay production has increased dramatically. It is partly due to growing food and energy needs but partly due to the environmental impact of the production process. Conventional films are based on petroleum, leading to trace amounts of microplastics being left behind in the soil. In addition, they are disposable and not biodegradable.

Some farmers are trying to solve the problem by burning the film, but this is a poor solution as it causes air pollution and releases toxic residues. A biodegradable silage film is an environmentally-friendly option because it is more rapidly degradable than conventional film. This solution is more costly but will protect the environment for future generations.


Silage film must have a high slip layer to protect the bale from damage during stapling and storage. The film also needs a high stretchability, between 50 and 100 per cent. A good stretch film should have an impact value of at least 10 grams/um.
