Water-soluble pva bag
Water-soluble degradation environmental protection garbage bag
A biodegradable water-soluble bag made of a special raw material such as polyvinyl alcohol, starch and other environmentally friendly components, mainly used for micro water garbage bags, medical anti-infective washing bags, chemical film packaging and so on. Polyvinyl alcohol (PVA) is the only vinyl polymer that can be used as a carbon source and energy source by bacteria. It can be degraded 75% in 46 days under the action of bacteria and enzymes. It belongs to a biodegradable polymer material. The raw materials can be producted from non-oil routes on a large scale.
main feature:
1. The thickness 35um-70um, width, bag length can be customized according to customer requirements;
2. the external color of the bag and printing (blue, black, green is more obvious) can be customized according to customer requirements; we can produce fully transparent and uniform color film and bag, because of the unique patented production process, our products use very little additive, so it is truly biodegradable, unlike conventional blow molding products, because of the additives, It is not completely biodegradable.
3. this product can add flavor, if there are special requirements, some flavor components will decompose when heated;
4. It can be used to load objects with less water content. For example, in rainy days, there is water on the bag and the bag will not dissolve and perforate quickly. The bag is discarded outdoors in the trash can, encountering sufficient water, (the water will soften, dissolve in 3 minutes in 60 degree water temperature, and slow in 20 degrees water temperature). It will decompose naturally in 45 days and dissolve 70% in humid environment. It will not pollute the ocean.
5. After cleaning indoors can be directly thrown into the toilet water to quickly soften and decompose, can be safely washed into the toilet, will not block the toilet;
6. It can be biodegraded by bacteria and enzymes in the soil after landfill, and it is an environmentally friendly product.
7.The PVA film or bag produced under normal conditions is light yellow and has the acidity of acetic acid. Our latest generation of production process can produce a completely transparent product with only a slight acidity.
notes:
As early as 1996, China had studied the impact of polyvinyl alcohol on the environment.
The research progress of the impact of polyvinyl alcohol on the environment introduces the research results of the harm to PVA at home and abroad, the impact on the soil environment and the water environment. Studies have shown that the harmfulness of PVA is extremely low, such as a small amount of biological ingestion is harmless. Degradation in soil can improve soil physical properties, increase soil water permeability and moisture retention, and promote crop growth.

The factory is located in the chuangxin industrial Park of Leiyang City, Hunan Province. 2 hours high-speed railway journey from Shenzhen. With cheap manpower and development costs, so we could offer good products with cheap price to our guests.
There are several advanced PVA water-soluble film production lines, various packaging bags and shopping bag production lines in our factory. We have developed PVA films of various temperatures. Among them, PVA high-temperature film technology is the world's leading film technology, and there is a strong R&D team and management team in our factory. We are a new materials technology company specializing in the research, production and sale of water-soluble films (PVA-polyvinyl alcohol film).
PVA water-soluble film has excellent barrier properties, water solubility and environmental friendliness. It is one of the most successful green materials in recent years. It has been widely recognized by environmental authorities and users at home and abroad, and is increasingly used in packaging, textile embroidery and water transfer printing.
For example: pesticides, fertilizers, dyes, detergents, water treatment agents, mineral additives, detergents, chemical reagents for garden care, etc., can also be used as rapeseed, plant seed bags, clothing bags, food and hospital washing bags, industrial The packaging of various products such as supplies and electronic products can also be used for textile embroidery padding materials, water transfer printing, and film stripping. At the same time, the company successfully developed packaging bags and supermarket shopping bags for various application scenarios this year. Customized bags and shopping bags of various specifications.
The factorey specializes in product quality, technology improvement and product innovation, and is committed to providing customers with products and services that are satisfactory.
