What is grass film?

The grass film is a functional film that helps retain the nutrients of plants such as grass, corn, grains, and vegetables while preventing them from molding. In addition to being used directly as packaging film for these plants or made into bags for packaging, it can also be used as a covering film for fresh grass, hay, and grains.

The advanced silage technology currently is the wrapping silage technology. After shredding the harvested corn stalks and fresh grass, they are tightly compacted by a baler and then wrapped with silage plastic stretch film, creating a sealed fermentation environment for the grass bales. Under anaerobic conditions, the natural fermentation biochemical process is completed in 3-6 weeks. The finished product has an increased crude protein content, a reduced pH value, and an increased soluble total sugar content, achieving a high livestock intake rate. As a packaging product of the most advanced silage feed technology, grass film has been widely used in Europe, America, Australia, and other regions, with over ten years of mature usage experience.

Advantages of grass film:

1. Low cost, quick effect, and high comprehensive benefits.

2. High quality silage feed. Due to the good sealing of the stretch film wrapping, it improves the quality of the anaerobic fermentation environment for lactic acid bacteria, enhancing the nutritional value of the feed, resulting in high crude protein content, low crude fiber content, high digestibility, good palatability, and pleasant aroma, significantly improving the quality and yield of livestock meat and milk.

3. Minimal loss and waste, significantly reducing mold loss and feeding loss. Traditional silage losses can reach20%-30%.

4. Long storage and freshness period. With good compaction and sealing, it is not affected by seasons, sunlight, rainfall, or groundwater levels, and can be stored outdoors for2-3 years or more.

5. Convenient storage and easy access for feeding.

6. Environmentally friendly and pollution-free. Due to its good sealing performance, there is no leakage of liquid. The packaging is appropriate, compact, and dense, making it easy to transport and commercialize, ensuring a balanced supply and year-round use of modern animal husbandry silage feed for large, medium, and small dairy farms, beef farms, goat farms, and breeders.

Important considerations when choosing grass film:

1. Make sure to choose a professional manufacturer for grass film! Grass film is not just stretch film + color masterbatch!

In recent years, with the continuous popularity of grass film, many stretch film manufacturers in China have shifted to producing grass film due to the saturation and thin profit margins in the stretch film market, seeing this growing market. These stretch film manufacturers do not understand that true grass film is a special functional silage feed packaging film, which not only requires high shading, weatherproof, anti-aging, and UV resistance for long outdoor storage but also needs to provide an appropriate sealed fermentation environment for silage feed! This is beyond the capability of stretch film factories, and the stretching performance of grass film is far superior to that of ordinary stretch film!

2. Not all grass films are the same!

Grass film needs to be stored outdoors for long periods, so the natural environment of the usage location is closely related, especially the local seasons, light intensity, stretching performance, and humidity. This requires suppliers to adjust the color, formula, etc., of the grass film according to the user's situation. Of course, color is also related to the user's local preferences and habits. Non-professional so-called grass film manufacturers cannot achieve this at all.

3. Do not choose cast film for grass film!

Cast and blown extrusion are two production processes for plastic films, each with its advantages, but blown film is better for grass film!

1. The cast process requires high fluidity raw materials, resulting in low strength.
2. Cast film has an uneven appearance, poor sealing, which becomes more pronounced over long storage.
3. The low retraction strength of cast film leads to poor wrapping force, resulting in excessive oxygen content in the grass bales, which is not conducive to fermentation.
4. The processing temperature of cast film is higher than that of blown film, causing a large amount of volatile substances in polyethylene materials to evaporate at high temperatures, resulting in decreased material performance and severe thermal oxidation, leading to unstable product quality.

5. The tension of cast film is difficult to control, causing slippage, which becomes more pronounced over long storage.

You should know that Germany is the birthplace of grass film, and cast process grass films have been completely eliminated in Europe!

4. When choosing grass film, be sure to choose Salit grass film!

In China, there are only six professional manufacturers of grass film! Salit is one of them!

In China, only three manufacturers produce grass film using blown film technology! Salit is one of them!!

In China, only two manufacturers produce grass film using imported blown film equipment, and the only specialized manufacturer is Salit!!!

We, Salit, use professional imported German multi-layer co-extrusion blown film equipment! Professional formulas!! Professional grass film manufacturers!!!

We, Salit, are professional grass film exporters, selling to Europe, America, Australia, the Middle East, Japan, and South Korea, with zero complaints!!! Zero returns!!!

Characteristics of Salit grass film:

1. Excellent mechanical properties.

2. Protection level up to180KLY, effectively preventing damage caused by sunlight, especially UV rays, ensuring low light transmission and avoiding heat accumulation.

3. Consistent quality and thickness, with good25 micron thickness distribution across the film.

4. Good stretching performance (even in warm weather and cold winters).

5. No holes present when stretched.

6. Good adhesive sealing between layers.

7. Strong puncture resistance and excellent impact resistance.

8. Maintains mechanical properties for over a year even when stored outdoors.

9. Good sealing, blocking oxygen, air, and moisture penetration.

10. High load retention (for packaging integrity).

11. Ensures customers benefit from high-quality film standards. These include UV resistance, puncture resistance, adhesion, and stretching properties (55-70%), including thickness.

12. Specified properties ensure the film performs well during packaging, protecting and saving feed.

13. Specifically designed for grass packaging, saving valuable time for efficiency and long-term performance.

14. The silage grass film provides tightness in all three dimensions— meaning the "grass bale" has a more consistent strength and rigidity. This allows for much higher stacking of grass bales, as they maintain their shape better.
