5-layer coextruded films; PE-EVA-EVA-EVA-MLLDPE in combination with polyethylene types on basis of metallocene and EVA -copolymers.
Blue berry plants need full sun to grow and fruit well, proper moisture and temperature control.
Light control:
blueberry film provide outstanding light transmission.
Anti-dust effect for continuous high light transmission.
By test , if the blueberry under continuous exposure with 24-44 unit UV-B, it will get weigh loss and sunburn. We apply specific UV control technology for blue berry film. Allow 65% UV light pass to obtain most optimized condition .
Temperature control:
If the indoor temperature continuous exceed 39-40 degrees. Photosynthesis will be stopped and lead to results of lacking nutrition . we design specific diffused light for blueberry film, base on area difference, the diffusion level up to 80% to satisfy the blueberry photosynthesis and to keep the room temperature cool.
Moisture control:
The suitable moisture level is between 50-60%. We design anti condensation property to blueberry film to control the moisture level and avoid water droplets.
