1. Different uses.
Mulch film can not only improve ground temperature, water retention, soil conservation, fertilizer conservation and improve fertilizer efficiency, but also has many functions such as weedicial, pest control, drought and flood prevention, salt inhibition and seedling protection, improvement of light and heat conditions near the ground, and hygienic and clean products.
Plastic wrap can cover food utensils and protect them from bacterial infection; Wrap food for easy storage (e.g. sandwiches); Refrigerate the bowl covered with plastic wrap to remove the oil from the soup.
2. The composition is different.
Plastic wrap is a kind of plastic packaging products, usually made of ethylene as the masterbatch through polymerization reaction, plastic wrap can be divided into three categories: the first is polyethylene, referred to as PE; the second is polyvinyl chloride, referred to as PVC; The third is polyvinylidene chloride, or PVDC for short.
The mulch film is usually a transparent or black PE film, but there are also green and silver films.
3. The performance is different.
The plastic wrap is easy to pull out and cut; Easy to bond with glass, ceramic and stainless steel pasta (but not the plastic wrap itself); Nearly transparent and not wrinkled, uneven thickness; Able to withstand the pressure of general pulling.
The main body of the plastic film is a plastic film, and the membrane surface is planned as the ground and ditch with the bottom line of the ditch parallel to the longitudinal bisector of the film and the ridge lines on both sides of it, and the ditch film is divided into clear water film and soil covering film with the covering line parallel to the bottom line of the ditch.

<>1. Mulch film is a ground covering film, usually transparent or black PE film, but also green and silver film. It is used for ground mulching to increase soil temperature, maintain soil moisture, maintain soil structure, etc. It can prevent pests from invading crops and diseases caused by certain microorganisms, and promote plant growth.
2. Mulch film is a petrochemical product and polyethylene product. China's plastic film mulching technology was introduced from Japan in 1978. In the first few years, it was developed and tested in 13 provinces, municipalities and autonomous regions, including the three northeastern provinces, Beijing, Shanghai and Inner Mongolia, and after demonstration in 16 provinces and cities in agricultural regional production, it was determined that it is a science and technology suitable for promoting the transformation of traditional agriculture to modern agriculture in China.
Since 1983, it has been promoted to a large area across the country as a national key promotion project.
