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.
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.
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
The minimum thickness of film made of such material can be 10 microns.
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
