Nowadays, when farmers grow watermelons in greenhouses, they usually start planting in winter, but the production conditions in winter are not very good and the temperature is low. Therefore, when growing watermelons in greenhouses, it is stricter to choose special watermelon membranes. The following standards and quality requirements should be met when selecting:

1. Good light transmittance. The light transmittance is high and stable. The light transmittance should be kept relatively good after 4 months of use.

2. Good heat insulation performance. The thickness is not less than 0.11-0.12 mm (11-12 passes).

3. Good anti-fogging and dripping performance. No dripping function can be longer than 5-6 months.

4. Watermelon special film has good aging resistance. The service life of this product should be greater than 12 months.

5. Stable structure, convenient maintenance and convenient operation.

6. Choose a good brand with stable quality and good reputation after years of use.
