As a new conception environmental packing material, PP series of
water-soluble film has been widely used in water-soluble chemical
products and inner packing material used under the water in Europe,
Japan and other countries. For example: pesticide, fertilizer,
cleanse, water treatment agent, mineral addictive, concrete
addictive, chemical reagent for photograph and gardening. And also
as the inner package of seeds sheet, dress, food and hospital
laundry, the specialties of the products are as bellow:
1) Anti-falsification. It's the best weapon to protect the top
quality products, prolong the using time of the products.
2) Environmental friendly, can be 100% dissolved, nothing toxic
produced except the co2 and the h2o.
4) Safe, convenient, can prevent the people from contacting with
5) Can be weighted exactly, no waste.
6) Super tensile and split resistant, can be adhered and
2 Property of the products
1) Water ratio
the water-soluble film must be packed in PE plastic to make the
water unchanged, when out of the PE plastic, the water ratio will
change with the temperature, and the property will also be changed.
Sheet-1 Balance water ratio of water soluble film
Different from the other plastic film, the water-soluble film has
good antistatic property. When used in packing, the plasticity will
not be influenced because of static electricity, and no dust can
cling to the film.
Antistatic property of various films (refer to sheet 2)
Static volt (V)
3) Water and air transmissibility
The water-soluble film has strong transmissibility e to water and
ammonia, but can block the oxygen, nitrogen, hydrogen and co2.
these features can make the components of material packing
unchanged and keep fresh.
4) Sealability and agglutination
The water-soluble film has great sealability, can be used to heat
seal of resistance and high frequency. The strength of the heat
seal is relative to the humidity, temperature, pressure and time.
The film can also be sealed by agglutination, the alkyd is a good
Heat-sealed temperature of water-soluble film (conditions: pressure
of sealability: 0.2Mpa; time: 2 seconds; thickness: 0.03mm)
Temperature of sealability(℃)
5) High intensity and tensile resistance. It's better than any
other films in split resistance.

The strength of various films
Various patterns can be printed on the film clearly be normal
methods. Have been adopted in special printing,, like the Curved
7) Oil and organic resistance
The water-soluble film has good capability of resisting oil,
mineral oil, almost all fat and organic solvent. Keep the
water-soluble film away from strong alkali, acid, chlorine free
radical and other substances that react to PVA
The dissolution speed of the water-soluble film depends on the
thickness and the temperature. Relative data:
The soluble speed of water-soluble film (thickness: 0.03 water
A) Fast soluble film: disintegration<25 seconds
B) Medium soluble film: disintegration<10 minutes
C) Hard soluble film: can hardly disintegrate under 40℃ and
completely dissolved above 85℃
Our products can be divided into three groups by the dissoluble
A): Fast soluble film: packing for pesticide, cleanse, chemical
products, and as the package for only one time usage, like the
Sheet covered on the toilet, hospital laundry bag and so on.
B) Medium soluble film: seeds sheet, herbicide bag, wig, underlay
of embroider, package of food, cosmetic.
C) Hard soluble film: top grade textile, plastic bag, package of
buffer cushion, coating of book and paper
3 Specification (can process according to your special need)
Length: more than 500/roll
Width: optional between 200MM-1000MM
The film gains the advantage over others in transparency and
glossiness. This makes the packed objects brighter and has sense of
1. If the water ratio exceed 5%, water-soluble film can not be
2. If the package has been opened, PLS encased in PE film.
3. Preservation condition of the water-soluble film: 15～35℃;
4. During the usage, whatever problems you meet about the quality
and technique of the products, PLS contact the supplier.
