The Foamed Polystyrene (PS) is typically
white continuous foam which requires less energy to produce
as compared to other forms of disposable products. It is non-absorbent
and will not support bacteria growth. Also it is superior
in terms of hot and cold insulation. Foamed PS does not degrade
readily or is non-biodegradable but it is chemically inert
and will not release chemicals and gases that will eventually
pollute our groundwater and air. If disposed properly; and
since it is 100% recyclable, it will not harm the environment.
PS raw materials are sourced either locally or are being imported.
The Thermoforming production operates with contemporary machineries.
And can produce a wide variety of plates and trays, bowls
and food boxes from more than 40 different types of molds.
Another family of products is produced from Expandable Polystyrene
(EPS), EPS is from the same thermoplastic family as PS but
raw materials come to the plant in the form of beads. The
EPS is processed by heating the beads in steam and using heat
and pressure, the expanded beads bind together in sealed molds
to form products.
A third family of product is produced from Oriented
Polystyrene (OPS). Raw materials in the form of rolls
of specified width and thickness are obtained from
foreign sources. The sheets unwound from the rolls,
are pressured formed in very similar manner to PS
thermoforming. Again different numerous molds can
produce a variety of trays, boxes, lids and cup covers
using the pressure forming process.

A fourth family of product is produced from polypropylene
(PP). Just like PS, PP is 100% recyclable. PP raw materials
are obtained locally or imported from abroad and takes the
shape of clear granules of pellets. The PP pellets are heated
in the PP extrusion machine where the melted material is then
metered out of a die head into the gap of two press rollers
and the sheet then produced is wound into rolls. Sometimes
colorants are added.
As is very similar to the PS Thermoforming process, sheets
from the rolls are fed to the thermoforming machines which
heat the sheets forms the sheets into products depending on
the molds installed.
