| ¡¡¡¡De-oxygen
fresh-keeping agent series are the novel external (non additive
type) fresh-keeping agent and its main ingredient is activated
iron powder. It keeps product fresh through absorbing and
isolating oxygen and is environmental friendly and free of
contamination and thus widely used.
Working principle:
¡¡¡¡When this agent is sealed in a container together with the
product to be kept fresh, after 1 or 2 days, the oxygen concentration
in the said container will drop below 0.1%. Then the de-oxygen
fresh-keeping agent ceaselessly absorbs the penetrated oxygen,
keeps the product under no-oxygen state, destroys the survival
conditions for microorganism (bacteria and mold), protects
the fat and protein from decomposition and oxidation and thus
ensures product quality.
applications:
¡¡¡¡It is widely used for keeping fresh of moon cake, cake,
ground nut, mushroom, dried meat and fish products, tea, Chinese
medicine and herbs, powdered milk, and confetti as well as
for corrosion- and mildew proof of metallic products, films,
handicrafts and architecture.
Characteristics of product:
1, Physical fresh-keeping, safe, non-toxic, and free of odor
and side reactions£»
2, High oxygen-absorbing capacity, complete oxygen removal,
and superior to vacuum package (nitrogen-filling).
3, Slight impact by humidity and temperature.
4, According to the characteristics of the products to be
kept fresh, this series of fresh-keeping agents are divided
into common type, fast type, drying type and conditioning
type for option.
This series of fresh-keeping agents include model 30, model
50, model 100 and model 200.

Selection of types:
1. The fresh-keeping agents shall
be selected according to the requirements of the products
to be kept fresh, for example, for moisture-sensitive products
drying type agent shall be used, and for high moisture and
high-fat products fast type agent used.
2. The model of fresh-keeping agents shall be selected according
to the oxygen volume of the packing container.

Notes for application:
1. Before ordering, please indicate the type, variety and
moisture content of the products to be kept fresh.
2. Once unpacked, the de-oxygen fresh-keeping agent shall
be used up in 2 hours as far as possible, and remaining one,
if any, shall be immediately sealed and stored.
3. The better the barrier capacity of the packing material,
the more ideal the fresh-keeping effect. Generally, the oxygen
penetration rate of the packing material shall be below 50ml/m2.24h£¬25
¡æ, such as KOP/PE, KPET/PE, and ONY/PE.
4. The seal shall be flat and free of adhered dust or oily
water and have a width at least 5mm.
5. During transportation and storage it shall be protected
from punching by pointed objects.
