PS Foam Absorbent Trays
PS
foam tray is most widely used in the world as a food packaging trays for its
superior heat insulation property & cold resistance and a competitive price
by its so high foam ratio. Hence PS foam trays are used as packages of the
frozen/fresh foods especially. But
the freshness of the foods packed in PS foam trays is lowered considerably by the blood generated during the display in the showcases. Even the blood may cause the decomposition of the foods by the propagation
of the bacteria. To
remove the blood, non-woven fabric type absorption pads have been used but
there was a limit in absorbing the blood sufficiently. So such a problem as
blood absorbency can’t be solved with absorption pads completely.
To
solve this problem fundamentally, Samjin has developed a Absorbent Masterbatch for
PS foam absorbent trays capable of absorbing
the blood quickly and effectively. In
addition, it helps to keep the toughness of PS
foam absorbent trays same as that of the normal
PS foam trays. Namely PS
foam absorbent trays have not
only the economic feasibility but also the
practicality.
For
these reasons, PS Foam absorbent trays are now being used in the world widely.
Development Motivation
Absorbent
Masterbatch developed by Samjin provides a new
function of water absorbency to PS foam trays, which is one of the most innovative food
packaging methods.
PS
foam trays made of Absorbent Masterbatch absorb the
blood generated from frozen/fresh foods whiledisplayed in
the showcases quickly and effectively.
Features & Advantages
•
absorbs the water more
than 6
times of its
own
weight
•
absorbs the water quite quickly
• keeps the
toughness of the tray same as the normal PS foam trays

Applications
#01) Foods Packaging
• PS
Foam Absorbent
Trays for
the packages of frozen/fresh foods
• PS
Foam Absorbent
Pads for
the solid(non-foamed) sheet foods packages
※ Uses : Meats, Chicken, Fishes, Processed
Meats (Ham & Sausage)
※ Absorbent Pads
are quite
useful to absorb the water generated from the frozen processed meat
effectively while thawing them.
※ Advantages of
Absorbent Pads:
- More simple to produce
- More diverse applications
- More helpful for the recycling of the
wasted trays
- Much compact size => save the
logistic cost!
#02) Moisture Keeping & Control
Keeping
the moisture inside of the sealed foods containers especially
for fruits and/or vegetable at the certain proper levels
is much helpful to maintain the freshness of the contents which can be dried
during the distribution/display for sale. For
this, PS Foam Absorbent
Trays and Absorbent Pads can be used to keep the moisture by
wetting them prior to pack the foods.
In
addition, PS
Foam Absorbent Sheets can
be used as the interior
materials of
the constructions requiring to control the moisture inside of the rooms/halls
at the certain level.
