At present, many types of films are used in the greenhouse industry. Qingzhou Luhong Plastic Co., Ltd. will introduce the white mulch film. This product can be divided into polyvinyl chloride (PVC), polyethylene (PE) and ethylene-vinyl acetate copolymer according to the raw materials. There are three major categories of EVA.

1. Polyvinyl chloride (PVC) film

This agricultural film is produced by calendering. It has excellent thermal insulation properties and good flexibility. According to the function, it can be divided into PVC anti-fog film, PVC drip film, PVC seedling film and PVC ginseng film.

(1) PVC anti-fog film and PVC anti-drip film are mainly used to cover fruit and vegetable overwintering greenhouses. The product has anti-fog and anti-drip functions, and the anti-fog period is more than 3 months. The dripping time should not exceed 6 months. It has good low temperature aging resistance, good heat preservation effect and good light transmittance.

(2) PVC seedling film is mainly used for early spring rice seedlings. The product has the function of heat preservation and light transmission, which can meet the needs of rice seedling growth.

(3) PVC ginseng tablets have the functions of low temperature resistance, aging resistance, and light adjustment. It is a good material for ginseng covering.

2. Polyethylene (PE) film

This is a kind of white mulch film. This agricultural film is produced by extrusion blow molding. It has the characteristics of light weight, large unit area and convenient use. According to its function, it can be divided into PE anti-aging film, PE anti-aging non-drip film, PE anti-aging drop anti-fog film, PE plastic film, etc.

(1) PE anti-aging film products have good anti-aging properties and can be designed and produced according to user requirements.

(2) PE anti-aging non-drip film and PE anti-aging fog film are mainly used for greenhouse cover in early spring and late autumn. The invention has the function of defogging, reduces the fog in the shed, increases the light in the shed, increases the temperature in the shed, and has a long service life.

(3) Polyethylene plastic film is mainly used for covering early spring crops, and the covering period is 3 months.

3. Ethylene-vinyl acetate copolymer resin (EVA) film

The invention adopts the extrusion blow molding method to prepare agricultural film, which has the characteristics of good flexibility, good light transmission, good heat preservation performance and the like. It can be divided into EVA droplet anti-fog film and EVA droplet film. This product is a new type of energy-saving covering material with good anti-fog and anti-drip properties, which can reduce fog in the greenhouse, increase the light in the greenhouse, increase the temperature in the greenhouse, and help crop growth.

The above information is the classification of the white mulch that our company introduces to you. I hope our sharing can help you!
