The degradation rate in 100 days up to the adding ratio of it
Product Futures :
Granules are in light yellow and come in cylinder and round shape, with slight fragrance. They absorb moisture easily and are easily decomposed by microbes. They are anti-static. The processing temperature of them is lower than that of conventional plastic. They are easily colored. Such resin is a kind of additive which should be blended with polyolefin materials like PE, PP, PS, PVC, etc to process finish products.
Recommended Applications:
For all sorts of anti-static packing purposes, e.g. electronic product packaging, car interior covering film, electrical appliance packaging, agricultural mulch film, shopping bags, T-shirt bags, document folders, filter bags, storage bags, bin bags, tear-on-roll bags, disposable gloves, table cloths, aprons and rain coats, etc.

Common film blowing extruder, sheet extruder, bags making machine, printers, and heat sealing machines are all can be used.
Processing Technology:
Best results will be achieved with a screw L/D ratio ≥ 28:1. The blow-up ratio should be more than 1:3 to achieve the maximum production yield and the best quality.
BOR-M-501F can be blown with LDPE. It needs to add a certain proportion of (MFI~4) LDPE or LLDPE when blown with HDPE.
Newly made film feels brittle or crispy. Its elongation is low. This is due to severe dehydration during production. Therefore, the film needs to be settled for a 24- hour curing period to regain elongation and anti-tear strength before being used to make finish products, e.g. bag-making or printing.
The minimum thickness of film made of such material can be 10 microns.
Remarks:
Due to the high starch content, the resin easily absorbs moisture. So it needs to be stored in a dry environment. The package should also be sealed properly to prevent the ingress of moisture.
In case the resin is damp, it should be dried for 2 hours at 80ºC. Its processing temperature is 5ºC to 10ºC lower than that of PE. During processing, the temperature is correct when corn starch fragrance can be smelled at the hopper
It can be easily decomposed into soil friendly substances in microbial environment.
