PVA Water Soluble Bag
ANHUI LIWEI CHEMICAL CO.,LIMITED
[Introduction]
Water-soluble bags dissolve in contact with cold or hot (more than 50ºC or more) water, which makes them an excellent eco-friendly replacement for traditional plastics in the laundry sector. Contaminated textiles (blood, faeces, microbes, germs etc.) are placed in water-soluble bags and these are placed directly in the washing machine. This avoids any risk of contamination and infection in laundry, nursing home, hospital and hotel staff.
Made of Polyvinyl alcohol (PVA) and materials of natural origin, water-soluble bags are transformed into H2O and generate no microplastic waste and no damage to the environment. Water-soluble bags are considered biodegradable, are free of polyethylene and polypropylene and do no damage to the marine ecosystem once they are dissolved in water. They are 100% eco-friendly. All our water-soluble bags are certified biodegradable.
We stock a wide range of sizes. Water-soluble bags are customisable in size, serigraphy and type of closure.
Applications
Agriculture: Used for pesticide and fertilizer packaging to avoid direct contact with harmful substances and reduce environmental pollution.
Detergent Industry: Ideal as outer packaging for laundry pods and detergents, dissolving in water to release the product.
Healthcare: Suitable for medical supplies packaging, ensuring sterile operations and convenient use.
Food Industry: Applicable for packaging food additives and seasonings, ensuring food hygiene and safety.
Laboratory: Used for chemical packaging, ensuring a clean experimental environment and easy handling.
Features of PVA Water-soluble Bags
Eco-Friendly: PVA material completely dissolves in water and ultimately decomposes into carbon dioxide and water, meeting environmental standards.
Convenient to Use: Dissolves quickly in water, eliminating the need for additional disposal steps and improving operational efficiency.
Fast Dissolving: Rapidly dissolves even in cold water, saving time and resources.
Customization Service: Customizable sizes, specifications, and packaging designs to meet personalized needs.
FAQ
Q:What materials are bags made of?
A:The water-soluble bags are made of polyvinyl alcohol and natural materials.
Q:What is PVA (Polyvinyl Alcohol)?
A:Polyvinyl Alcohol (PVA) is a synthetic organic polymer. Its distinctive properties include high solubility in water and biodegradability in aqueous environments.
Q:Why is Polyvinyl Alcohol (PVA) biodegradable?
A:Polyvinyl Alcohol (PVA) can be degraded via photothermal, oxidative, and biological processes (microbial and biochemical actions). Multiple studies have shown that at least 20 different species of bacteria, along with various molds and yeasts, are capable of degrading Polyvinyl Alcohol (PVOH), converting it into carbon dioxide, water, and biomass.
Q:Is Polyvinyl Alcohol (PVA) toxic?
A:Polyvinyl Alcohol (PVA) is non-toxic. It is widely used in household products and food packaging. In the medical field, it serves as a coating for capsules and tablets, an ingredient in artificial tears, and in cosmetics, it acts as a binder for chemical components. Toxicological studies have shown that the human body's absorption rate of this substance is extremely low, so it can be safely taken orally.
Q:Which industries can use LIWEI bags?
A:LIWEI bags can be used in retail, supermarkets, postal delivery, clothing packaging, and (dry) waste disposal, among other applications.
Q:Is there a single type of Polyvinyl Alcohol (PVA) material suitable for all types of packaging bags?
A:Unlike traditional plastics, PVA allows for customized production formulations of LIWEI bags based on the specific applications required by customers.
Q:What is the difference between LIWEI bags and compostable bags?
A:Although LIWEI bags are compostable, they can be disposed of without any composting system. This makes them an ideal choice for markets lacking composting facilities, which are required to simulate the degradation conditions for compostable bags (such as PBAT, PLA, and starch-based ones). On the other hand, LIWEI bags dissolve in aquatic environments (e.g., rivers, oceans, and lakes), whereas compostable bags do not.
