Hay film ( Silage Wrap Film ) is an agricultural film specifically designed for packaging forage, silage, and round-bale feed. By wrapping baled forage, the forage film helps prevent air and moisture from entering, creating a stable, airtight environment for silage storage and thereby reducing losses during the storage process.

Our forage film utilizes New LLDPE material It is manufactured to deliver excellent tensile strength, adhesion, and puncture resistance. The film’s surface is tacky, enabling tight conformability when applied in multi‑layer wraps to form a continuous sealing barrier. Available in white, black, and green, the product can be supplied in various widths and lengths to suit different packaging equipment and application requirements.

I. What is forage film?

Pasture film is also known as Silage film, silage wrapping film, or Silage Wrap Film , primarily used for wrapping round bales of hay and other silage.

After the forage bales are formed, a wrapping machine is used to apply a uniform layer of stretch film around the exterior of each bale. Once the multiple layers of film bond together, they help prevent air and moisture from penetrating the bale, creating a more stable packaging environment that supports silage fermentation and long-term storage.

Compared with direct open-air stacking of forage, sealed packaging with forage‑preserving film can minimize the impact of rain, air, and the external environment on the feed, while also reducing losses during transportation and storage.

Hay‑silage film is widely used in pastures, farms, dairy cattle operations, beef cattle farms, and silage production facilities.

II. Main Features of Forage Mulch Film

1. Produced from virgin LLDPE material

Pasture film is used LLDPE (Linear Low-Density Polyethylene), virgin material It is produced with excellent flexibility and mechanical strength.

High-quality raw materials help the film maintain stable tensile properties during the winding process and reduce the risk of tearing during packaging.

2. The surface exhibits excellent adhesion.

The surface of the forage film is adhesive, allowing the individual layers to bond with one another during the winding process.

After multiple layers of wrapping, the film forms a tight seal that minimizes air and moisture ingress into the bale, helping to preserve the storage quality of silage.

3. Excellent puncture resistance

Pasture grasses often contain relatively tough or sharp stems; if the film lacks sufficient strength, it may tear during the wrapping process.

Hay‑wrap film boasts excellent puncture resistance, enabling it to better withstand the baling and wrapping processes and minimizing air leakage caused by film rupture.

4. Waterproof Sealing

Hay bale film offers excellent waterproofing. After multiple layers of wrapping, it helps prevent rainwater and moisture from penetrating the bale.

For silage bales that require outdoor storage, a robust outer wrap can mitigate the impact of weather fluctuations on the feed.

5. Reduce storage and transportation losses

Silage wrap is used not only for silage fermentation but also to provide external protection for hay bales.

During transportation and storage, intact film packaging helps protect feed from external environmental factors, thereby reducing transport losses and waste.

III. Specifications of Forage Film Products

Our forage wrap films are available in a variety of widths, lengths, and colors to meet the diverse needs of round balers and silage packaging.

IV. Forage Film in Different Specifications

Depending on the packaging requirements of different customers, we can offer bale wrap films in a variety of specifications.

25 cm wide forage film

Suitable for silage packaging applications requiring a narrower wrap width, allowing easy selection based on bale size and baler specifications.

50 cm wide forage film

A 50 cm width is suitable for standard round bale wrapping of forage, striking a good balance between efficiency and coverage.

75 cm wide forage film

The 75-cm-wide silage film offers a wide coverage width, making it ideal for silage‑packaging operations that require high packaging efficiency.

Different equipment and bale sizes require different film widths; therefore, prior to purchase, it is recommended to verify the specifications based on the specific baler model and operating conditions.

V. What are the applications of forage mulch film?

Silage wrap is primarily used for bale wrapping of various silage grasses and feedstuffs.

Common applications include:

Alfalfa silage

Corn silage

Ryegrass

Oat grass

Natural pasture grass

Leguminous forage grasses

Mixed forage grasses

Other silage feeds

The main use cases include:

Dairy Farm

Beef cattle ranch

Sheep farm

Large-scale agricultural farm

Silage production enterprise

Agricultural cooperative

Forage processing enterprise

6. Why does hay‑silage film require multi‑layer wrapping?

Haylage film typically requires multi-layer wrapping using a wrapping machine, rather than being covered with just a single layer.

Multi-layer films can create a more continuous and stable packaging structure. Once the individual film layers are bonded together, they help minimize the ingress of air and moisture into the bale.

An appropriate wrapping method can also help enhance the integrity of bale packaging, reducing the risk of damage during storage and transportation.

In practical applications, the appropriate wrapping method should be determined based on factors such as forage moisture content, bale density, baler settings, and storage duration.

VII. How to Choose the Right Forage Film?

1. Select the width based on the packaging equipment.

Different round balers and stretch‑wrap machines may have varying requirements for film specifications.

Before purchasing, verify the film width supported by the equipment and select a specification—such as 25 cm, 50 cm, or 75 cm—based on the bale dimensions.

2. Select products based on the storage environment.

If bales are to be stored outdoors for an extended period, particular attention should be paid to the film’s sealing performance, puncture resistance, and weatherability.

3. Focus on the adhesion performance of the thin film

Good adhesion ensures tight bonding between different film layers, minimizing issues such as loosening or incomplete packaging during the winding process.

4. Focus on film strength

Sharp edges may be present on the stems of forage crops and on the surface of hay bales; therefore, forage‑wrap film must exhibit excellent tensile strength and puncture resistance to minimize damage during packaging.

VIII. Color Selection for Forage Mulch Film

We currently offer the following standard colors:

White pasture film

Black mulch film

Green forage film

Different colors can be selected based on customer market demand, brand requirements, and storage conditions.

For bulk‑purchase customers, color and packaging options can also be further customized to meet specific requirements.
