Pva Film for Water Treatment Agent Packaging Pouches
Packaging Film / Bag
A water soluble, biodegradable polyvinylalcohol (PVA) film, ideally
suited for many packaging applications. Water soluble PVA bags,
sachets or pouches created from this film, provide a convenient,
safe and economical delivery system for a wide range of products
including detergents and cleaners, degreasers, concrete additives,
pigments, biocides, water-treatment products, agricultural
products, and others.
Agro Chemical Film
Chemicals used in agriculture are usually highly toxic, cause
severe pollution and endanger our health. Therefore, people have
been paying more attention to the materials of agricultural
packaging. Although being used for a long time, chemicals of
regular agricultural packaging have three main disadvantages.
Firstly, liquid agriculture chemical is packed in glass bottles
which are easily breakable, and cause leakage of toxic chemical.
Secondly, a lot of leftover in packaging produces a large amount of
chemical waste. Thirdly, if the agricultural chemical packaging
with leftover were to be discarded in rivers, rivulets, farms or
terra, etc. it would pollute the soil and water, which would be
hazardous to the environment in the long term.
Laundry Bags
pva film laundry bags are used in hospitals to minimize the contact
hospital workers have with contaminated clothing and bedding. Dirty
items are put into these special bags, which are then placed
directly into the washing machine. Because pva film is soluble in
water, the bags dissolve and are washed down the drain with the
dirty water. At the completion of the washing cycle, the clean
clothes are removed from the washing machine.
