Biodegradable Mulch Film
"SUNBIO"

Name: Biodegradable Mulch Film SUNBIO
Brand: Sunplac Corporation

Certified with the Biodegradable Plastic Mark

This Labeling assures the biodegradability and the environmental safety.

Registration No.: No.463, No.1043

SUNBIO is biodegraded to water and carbon dioxide by bacteria in soil.

Labor in Harvest can be saved because you can plow the film into soil without tearing it off.

You can use harvest machines without any trouble, because the film does not wind around the machines.

High harvest yield is promising, because SUNBIO has high heat-retaining property in addition to moisture retention property.

Color

Translucent / Black / Super White / Green (Preparing for Relaunch)

Thickness

Approx. 0.018 mm

Width

85-180 cm (Black: 65-180 cm)

Length

200-400 m (Up to 600 m depending on the width)

Sample: Translucent

Black

Total light transmittance 4% or less

Highly effective for weed suppression and suitable for spring, summer, and autumn crops in warm regions.

Notes: Because light transmittance is low, it does not raise soil temperature.

Translucent

Total light transmittance Approx. 90%

Highly effective at raising soil temperature and suitable for use in cold regions and for early spring planting or winter crops in warm regions.

Notes: Because total light transmittance is high and weeds can grow, weed control is required.

Green

Total light transmittance Approx. 30%

Provides weed suppression while raising soil temperature.

Notes: Performance between black and Translucent
Soil-temperature increase
(Translucent > Green)
Weed suppression
(Black > Green)

Super White

Total light transmittance Approx. 50%

Highly effective at suppressing soil temperature and suitable for crops prone to heat damage.

Notes: It has no weed-suppression effect, so weed control is required.

Spring

Summer

Designed for a laying period of 2 to 3 months.
When making holes, use circular cuts and avoid straight or T-shaped cuts.
Lay the film slightly loose. Stretching it too tightly may cause early tearing or shorten its life.
Fumigants such as chloropicrin or sodium carbam agents (Kilper) may shorten the film life.
When plowing in, make sure the film is well buried in the soil. If exposed on the surface, it may scatter or fail to decompose.
Heat and moisture retention may be slightly lower than polyethylene, so please take care with crop management.
When not in use, keep it free of soil and moisture, place it in a plastic bag, and store it indoors in a cool, dark, well-ventilated place.
Film strength may decline depending on storage conditions, so please use it within one year.
Decomposition may accelerate depending on soil, season, and weather conditions such as high temperature or heavy rain.
Do not use it for purposes other than agricultural mulch film.
