We are one of the leading suppliers and exporters of water soluble films. These are available in innovative designs, pattern and styles.
Water-soluble PVOH film is made from water soluble polymers, having the appearance of a common plastic film. It has unique characteristic of completely dissolving in water at room temperature. The dissolved film disappears in water like sugar or coffee and the ingredients of the film change their appearance but remains present as dissolved solids in water.
The rate of dissolution depends on agitation, water temperature, amount of water and thickness of the film. The PVOH has proved to be a revolutionary film with its multiple uses which has been acknowledged and hailed by not only satisfied users but also ENVIROMENTAL PROTECTION AGENCY strongly recommends in packing agriculture chemicals and pesticides in this water soluble film as it is completely biodegradable and safe for environment and with time to come the use of this film not only going to increase but also indispensable because of its biodegradability, eco-friendly with multiple uses.
The Time of Dissolving of the PVA Film
(eg: thickness:30um temperature:25℃.)
Type | The beginning of dissolving (sec.) | Total dissolving (sec.) |
Quick | <25 sec. | <5 minutes |
Middle | <5 minutes | <50 minutes |
Difficult | can't dissolve when temperature is under 40℃ | total dissolving when temperature is over 80℃ |
According to the time of dissolving, the film has three types: Quick, Middle and Difficult. Thicker film dissolve slowly, and the higher the temperature, the faster the film would dissolve in water.
Item | Fast soluble film | Medium Soluble Film | Difficult soluble film |

Water soluble laundry bags are an effective closed handling system in the medical industry where safety and high sanitary standards are vital to prevent the spread of infectious components. Handling is safer when the contaminated linen or clothing is isolated in a water soluble bag from the point of filling to the laundry machine or disposal point. PVA bags soluble is made to handle moist linen. The bags dissolve completely in the laundry, leaving no contaminated packaging waste. In addition, PVA bags are biodegradable and have odour barrier properties.
2. Embroidery
By using water-soluble PVA film as the proximal cloth,
time can be saved more than by using a paper. Water-soluble
PVA film increases dimensional stability, you can make more
beautiful embroidery. Water-soluble PVA film can be solved by cold
water, so you can wash away the film without damaging the clothes.
3. Agriculture Usage
Seeds are packaged in tape-shape at regular intervals using water-soluble PVA film. Because it germinates at the regular intervals when buried it in earth, the labour of the cull can be saved. Work simplification can be attempted when making the seeds of the lawn and the flowers adhere to water-soluble PVA film and making it into sheet. It can not only prevent the seeds from being blown away by wind and eaten by animals. But also can keep moisture in the sand.
4. Chemical packing
Agriculture chemical usually has the problems of high concentration and hypertoxicity and do harm to human being. If using PVA film the infection coming from venomousness or stimulating materials can be greatly reduced.
