(Summary description)Watermelon special film is selected according to the season. The film is basically used in northern winter. This film is not only weather resistant, but also has strong light transmission and thermal insulation functions.

Greenhouses are covered with straw curtains or insulation covers, which are usually used for insulation. It separates the space into individual enclosed spaces to retain heat and prevent internal and external heat exchange. But the straw curtain just cuts out the movie. In order to keep the temperature in the greenhouse constant, the influence of the thickness of the special film for watermelon on the thermal insulation effect of the greenhouse was studied.

1. With the help of larger bonding force and film shrinkage, the goods are tightly fixed as a whole, so that the scattered fragments become a whole. Even in the dark, the goods will not loosen, separate, no sharp edges and stickiness to avoid damage.

2. Maintenance: Surface maintenance provides a bright maintenance surface for the goods to achieve the purpose of dustproof, oil-proof, moisture-proof, waterproof and anti-theft. Packaging can make the packaging material bear uniform force and avoid damage caused by uneven force, which cannot be achieved by traditional packaging methods.

3. Fastening: Use the shrinking force of the elongated film to pack the goods together to form a compact and space-free unit.

Watermelon mulch film is used every year in the watermelon planting season and off-season, which can reach the breeding temperature of watermelon seedlings and grow well. Watermelons come in different varieties and densities. Density can be used to identify the plastic, but since the density of the foam is not the true density of the material, the foam should be separated at this point. In actual industry, the density of plastics is also used to separate plastics.

The special film for watermelon should be a transparent film with high light transmittance, strong heat insulation, high pressure resistance, pesticide resistance, strong chemical resistance and high chemical fertility. The reclaimed site needs thick film every year, which can be replaced after 2-3 years of continuous use. No thick film is used, it can be harvested in a short time and changed every year.
