What Are the Benefits of Using PVOH Water Soluble Film?


PVA Water soluble films, cold water soluble , embossed

PVOH water soluble film (also called PVA water soluble film), or polyvinyl alcohol film, is a kind of green packaging material that can solve the world’s “white pollution” problem . It has many special properties and is widely used. And the market is very broad, has been widely concerned in the world.
The main raw material of the PVOH water-soluble film is polyvinyl alcohol. As a new concept of environmental protection packaging materials, PVA water-soluble film is widely used in water-soluble chemical product packaging bags in Europe, America, Japan, and other countries. For example, as the packaging for the pesticides, fertilizers, fuels, cleaning agents, water treatment agents, minerals, detergents, concrete additives, photographic chemicals, and garden care chemicals, etc.,  It can also be used as rapeseed, plant seed bags, clothing bags, food and hospital washing bags and other products inside and outside packaging bags.

The Ultimate Guide To PVA Water Soluble Film

Advantages of the PVOH water soluble films

     Safe and non-toxic

The water-soluble film is safe, non-toxic, non-irritating, and easy to degrade. Dissolved in water, the final degradation products are              carbon dioxide and water, which can be absorbed by the human body and excreted through metabolism.

    Environmental protection and easy to dissolve

The water-soluble film is colorless and transparent, and it can dissolve in water quickly. After dissolving, the contents of the film packaging are released so that the effective ingredients quickly play a role. Also, the solution is neutral, its components have no pollution to the environment ,so it is a kind of environmental protection product.

     Oil resistance and corrosion resistance

The water-soluble film doesn’t dissolve in most organic solvents (such as benzene, xylene, etc.) and all animal oils, vegetable oils, and          petroleum hydrocarbons , but dissolves in glycerol, ethylene glycol, amide, triethanolamine, and ethanolamine salt and dimethyl –  maple.

      Prevent static electricity

The water-soluble film is a kind of anti-static film that, unlike other plastic films, has good anti-static properties. In the process of               using water-soluble film packaging products, it will not cause the reduction of plasticity and electrostatic dust performance because of          static electricity;

      Elastic tensile strength

When the water soluble film’s thickness is 0.03-0.05mm, the tensile strength is 100-300 kg/square centimeter, the elongation is 10-600%, the hardness is less than 10 Shore hardness.
So it is easy to make bags and simple processing because of its good flexibility . People can custom all kinds of sizes of packaging with this soluble films

       Accurate measurement

The unique elastic modulus and tensile strength of water-soluble film make it have high mechanical automatic packaging                                 performance, suitable for all kinds of automatic filling machines, improve the accuracy of dosage;

       Strong heat sealing

Water-soluble packaging bag has good heat sealing properties, the heat resistant temperature is up to 140℃, suitable for resistance               heat sealing and high-frequency heat sealing;

       Breathable oxygen resistance

The water-soluble film has strong permeability to water and ammonia, but has a good barrier to oxygen, nitrogen, hydrogen, and                   carbon dioxide gas. These features enable it to keep the ingredients and original smell of the packaged products in good condition,                protect the activity of the contents, and improve the effective use rate of pesticides;

        Clear printing

All kinds of color patterns can be printed on the film’s surface through ink, and it has good printability.

Application of the PVOH water soluble films

1. Agriculture and chemical industries

(1) Lining bags for the inner packaging of pesticides and chemical products.

The soluble bags and products can  dissolve in water together, which can avoid touching pesticides and chemical products directly.         Compared with traditional plastic bags, pesticide residues will not appear in plastic bags to achieve effective use of pesticides or chemicals.

(2) Seed bags.

The seeds are packed at fixed intervals and then buried in the ground, saving valuable seeds, which can save the busyness of  thinning seedlings;

As the inner packaging, the PVOH water soluble bag is pollution-free, non-toxic. After it dissovles in water immediately , the formation of gum liquid can gradually penetrate the soil, increasing the soil group adhesion and air permeability and water retention, so it is very suitable for soil reform.
PVA polymer is easy to be decomposed by strains in soil. It eventually degrades into water and carbon dioxide (H2O and CO2).  And It has complete water solubility and biodegradability and is a green environmental protection product.

2. Construction industry

As the Cement additive (silicon powder, etc.) packaging bag. To ensure the precise and quantitative addition of additives and avoid dust flying harm to the environment.  Especially for situation which needs to add glass fiber and basalt fiber, etc. (can improve its tensile limit strength, which can be increased by 30 ~ 50%), using water-soluble bag packaging is the most convenient and reasonable way.         Moreover, a small amount of PVA in concrete also has the effect of increasing bond strength.

3. Textile industry

Embroidery, wig, and other fabric carriers.As the carrier, easy to clean;

4. Building materials industry

As the large artificial stone release film. It has more advantages compared to other kinds of release films .

(1)Good detachment performance, it is not easy to produce hair embryo after film removal, saving grinding time;
(2) High softness and smoothness, the pva film can be more fit to the mold, and the film removal quality is higher;
(3) Good heat resistance, its heat resistance up to 190 degrees;
(4) Good mechanical properties, it has large tensile strength, high elongation at break;
(5) It is suitable for continuous production, high production efficiency.

5. Medical Industry

Hospital or laundry room laundry bags. Cleaning personnel does not need to contact the contaminated clothes directly to avoid cross-infection.

6. Daily chemical industry

Laundry pods, liquid detergent packaging.

The laundry pods contain highly concentrated cleaning and care ingredients with very little water content. It does not need to be measured. Just one bead can easily clean 6~14 dirty clothes. With convenient use methods and efficient decontamination, the laundry pods quickly became popular, and the market steadily grew. According to the industry standard of laundry beads, the active substance content in laundry liquid accounting for 15%~25% is called ordinary type, 25%~30% is called concentrated type, more than 30% can mark “concentrated laundry liquid” mark, more than 45% can mark “concentrated +” mark and the active substance content in laundry beads generally exceeds 45%.

As the “third generation of laundry technology,” laundry condensation beads are far more convenient than laundry liquid and laundry powder and have some advantages regarding cleaning effectiveness. Their effective cleaning ingredients are generally higher than the national standard laundry liquid formula, and their cleaning strength is stronger than traditional laundry products. Still, they also integrate multiple ingredients into one.

7. Packaging industry

The Fruit vegetable fresh-keeping packaging, supermarket shopping bags, and garbage bags.

Because of its good anti-static property, it is also often used to package electronic products.
