As the saying goes, there is no good cheap goods, buy agricultural film can not only map the moment of the cheap, but also remember four words: look, touch, pull, check. Look at the appearance of agricultural film is smooth, with no stain, with or without cracks, transparency is good. Smooth and transparent appearance, generally good quality, and vice versa.
Then grasp the agricultural film in his hand and pinch if it is soft, and then feel the thickness of the agricultural film. Soft, elastic and relatively thick agricultural film is generally a good quality agricultural film.
You can also try to pull the peasant film in your hand and pull it. The longer you pull it, the better the resilience. In general, cutting off a piece of agricultural film that is about the same length as a cigarette, pulling it hard, and pulling up the length of five cigarettes means that the quality of the agricultural film is good.
The last is "check." That is to check whether the manufacturer is standardized, whether the production process and equipment technology are good, whether the packaging meets the requirements of the country, and whether the information of the plant site, telephone number, trademark is complete, and more importantly, the after-sales service is better. Of course, to buy a good agricultural film must take into account the factors of light transmission, heat preservation, aging resistance, dripping, and anti-fogging.
