What is the difference between plastic wrap and mulch film 5

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.

Plastic wrap can be used to wrap food, mulch film cannot. It can be seen that plastic wrap is less harmful to the human body.

The production cost is not the same, and the degree of impurity removal of the main raw materials is different, and it is generally required to use degradable ones.

PVC makes plastic wrap, keep your mom fresh, that thing is poisonous, make garbage cans.

Hello, it's a pleasure to answer this question for you. The first is that the use is different, the plastic film can not only improve the soil temperature and balance stool, soil protection, water retention, fertilizer protection and improve fertilizer efficiency, but also can control weeds, diseases and insects, and other coarse carrying functions. Plastic wrap is to cover the food these, so as not to be exposed to bacteria, and then easy to preserve.

The second is that the composition is different, the plastic wrap is a plastic packaging product, and the mulch film is a transparent or black PE film.

The third is that the performance is different. The plastic wrap is easy to pull out and cut. The main body of the mulch film is a plastic film, which is parallel to the bottom line of the furrow parallel to the bisector of the film.

To put it simply, plastic wrap is commonly used on food, and mulch film is generally used for planting and growing vegetables.

Hope it helps, thank you.

<>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.

Mulch film is a ground covering film, usually transparent or black PE film, but also green and silver film, which is used for ground covering to increase soil temperature, maintain soil moisture, maintain soil structure, prevent pests from invading crops and diseases caused by certain microorganisms, etc., and promote the function of plant growth.
