Agriculture Film, Mulching Film, Material Bags

What’s Agriculture Film?

Agriculture film is mainly used for agriculture planting and crop protection. It can be divided into different types, common ones are: greenhouse film and mulch film.
Agriculture film is mainly made from polyethylene (PE) and EVA.

Agriculture Film Uses

Agriculture film is often used in greenhouse construction to provide appropriate temperature, humidity and prevent cold, dryness and other adverse effects of climate change.

What’s Mulching Film?

Mulching film is a type of agriculture film, made from polyethylene (PE). The mulching film is especially used to be laid on the farmland ground. It is available in different colors (such as black, white, silver, etc.) to meet the needs of different crops.

Mulching Film Uses

Mulching film is mainly used to control surface water evaporation, maintain soil temperature, and reduce weed growth, thereby promoting crop growth and increasing agricultural yields. Black mulching film is used to increase soil temperature and suppress weed growth, while silver mulching film is used to cool the soil, reflect sunlight and reduce pest infestation.

What’s Material Bag?

Heavy duty material bags are made from polyethylene(PE) as raw material, and other fillers (such as antioxidants, anti-static agents, etc.) can also be mixed and added to enhance the physical properties of the bag. Mainly used for packaging and transporting heavy materials, such as chemical materials, feed, grains, fertilizers, building materials, etc. This kind of bag has high tensile strength and durability, and is suitable for high load-bearing requirements.

Material Bag Use

Material bags are widely used in heavy-duty packaging across various industries due to their high abrasion resistance, tensile strength, waterproof and moisture-proof traits.

1. Chemical industry: Used for storing and transporting materials in powder, granule and liquid forms.
2. Agriculture and feed Industry: Loading agricultural products such as grains, fertilizers, and animal feed.
3. Construction Industry: For transporting and storing building materials like cement and sand.
4. Food Industry: Storing large quantities of food materials (such as sugar, flour, etc.), but must ensure compliance with compliance with food-grade safety standards.

Why do agriculture film, mulching film and material bags need to be made by using the multi-layer blown film machine?

Agriculture film, mulching film and material bags are made by using multi-layer blown film machine, mainly to enhance the function and performance of materials to adapt to more harsh application environment. The multi-layer blown film machine can combine materials with different characters in layers to make a multi-layer structure film, so that it has better strength, durability and functionality.

1. Enhance physical strength and tear resistance

   HDPE and LDPE are combined in different layers to provide the film better structural strength and pressure resistance.

   Application: Agriculture film need to withstand wind pressure and temperature fluctuations inside and outside the greenhouse. Material bags need to bear heavy loads. Therefore a multi-layer structure is necessary to enhance durability.

2. Provide waterproof, breathable and isolation properties

   In the middle layer of the film, high-barrier materials like EVA can be used to provide waterproofing and moisturizing retention, while LDPE can be used in the outer layer to enhance breathability.

   Application: Agriculture film and mulching film need to control surface water evaporation and maintain moisture, therefore the combination of breathable and waterproof layers are essential.

3. Achieve functional division and cost control

   Multi-layer blown film technology can use materials with excellent performance and higher prices in different layers, while using more economical materials in other layers to achieve a balance between function and cost, and avoid unnecessary high-cost material in single layer.

4. Enhance hot-sealing for easier processing

   The design of multi-layer can optimize hot-sealing of the film, facilitating the sealing operations during the bags making process, and ensure airtightness. The material formula can make the material characters of each layer improve the overall processing adaptability and product quality.

The application of multi-layer blown film machines enables greater flexibility and versatility in the production of agriculture film, mulching film, and material bags. This maximizes the performance of the materials and makes more economic benefits, allowing these products to perform optimally in various environments.
