Flash-Spun material · Agriculture
Reflective mulch, fruit protection and sunshades
Single-material HDPE Flash-Spun for the field: reflective mulch (D702), fruit protection bag (D503) and individual sunshade (D701). Properties as declared by the manufacturer; agronomic performance is validated for each crop and area.
How it works
Specular reflection
Glossy surfaces: light is reflected in a concentrated beam, in a single direction.
Dawnsens® diffuse reflection
Light is scattered more evenly towards the lower canopy, according to the manufacturer.
Field result — Gan Ping mandarin
With Dawnsens® film
Without film
According to manufacturer data: more even colouring and a higher share of marketable fruit.
Natural weed control
With Dawnsens® film
Uncovered
Up to 90% weed suppression with D702 film (citrus orchard). Blocking light reduces the need for herbicides — according to manufacturer data.
Reflectance measured by an independent laboratory
Up to 90.2% solar reflectance (SCI) for D702 film
Verified by the independent laboratory SGS (report SHMR260400806402, standard ASTM E1164-23, Apr. 2026) — SCI 90.20% / SCE 89.40%
Temperature inside the fruit bag — D503 model
Continuous 24-hour measurement on a sunny day. At the hour of peak radiation, the temperature inside the Dawnsens® bag was 30.9 °C, compared with 34.1 °C in a conventional paper bag.

Results in other growing regions
Apple (Shandong) · Grape (Sichuan)
Harvest brought forward by 7 to 10 days with D702 reflective mulch.
Orange (Zhejiang and Sichuan)
Better soil moisture control and a sugar content increase of 1–2 °Brix.
Grape (Liaoning)
Easy to install and highly durable: the film is reused over several seasons.

135 cm
Hydrostatic resistance (water column)
70 g/m²
Grammage · rigid version
- High protection against rain.
- Prevents sunburn from direct sun on the fruit and reflects UV radiation.

Field case — vineyard, Yunnan (China)
Manufacturer’s field project in Yunnan (Mengzi): a new grape variety in which the manufacturer attributes better colour change to the diffuse reflection of the mulch under the trellis.
Case reported by the manufacturer in China — not a trial carried out by KRONO or in Spain.
