Pva Film 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.
1. 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.
2. Cement/Dye/Enzyme Film
Cement additives/dyes/enzymes are alkali, acidic and neutral in
nature. Commonly used outdoors, cement additives, if not
controlled, can easily cause injury to the operators' eyes and
skin. Operators protect themselves by using a variety of protective
clothing and accessories to avoid personal harm. In recent times,
there has been an increase in the use of pva films in the packaging
of dyes, cement additives and enzyme in order to minimize pollution
and to provide a consistent dose during the manufacturing process
of the product. By using PVA film, the mixing operations have
become simple and the additive measures are more exact.
