Water soluble bag manufacturers offer products that dissolve in cold or hot water. These bags are a sustainable alternative to single-use plastics, and have a long history of use in the medical industry. They are also ideal for packaging powder agrochemicals as they avoid direct contact with the product packaged. The company offers a range of bag sizes and styles.

Manufacturer of standard and custom bioplastic packaging products including bags, forks, bowls, balls, bottles, toothbrushes and cooking oil containers made of polyvinyl alcohol (PVA). Resins, films and fibers are also offered. Serves the food, electronics, jewelry, textile and other industries. Products are available in rollstock and in a variety of application specific grades. Custom printing and embossing services are available.

PVA is a synthetic organic polymer, which can be produced from petroleum, natural gas, or other renewable feedstocks. The polymer is formed by crosslinking monomers with the addition of water and oxygen. PVA is highly water soluble in aqueous solutions, and is able to absorb water from the environment. PVA is non-toxic and has good thermal stability. The oxidation of PVOH to form carbon dioxide and water can be enhanced by UV radiation or exposure to other oxidizing agents.

Several embodiments of the present invention are especially adapted for use in producing laundry bags. The composite film of the present invention may be bonded to an additional hot water soluble sheet of material. The cold water soluble portion of the bag is positioned to be kept out of contact with the laundry, while the hot water soluble portion may be located in an area to be retained by the washing machine when the bags are in use.

The hot and cold water soluble bags of the present invention are particularly useful in isolating contaminated linens at hospitals. The bags can be used to contain the contaminated linens during the cold wash laundry cycle, and then completely dissolved in the hot wash laundry cycle, so that staff does not have direct contact with the contaminated linens. The bags can be easily sealed after use.

While these bags have great advantages, they do not provide a true solution to the problem of single-use plastics. While they can be disposed of in a waste stream, they do not provide for an end-of-life strategy that can be considered a genuine part of a circular economy. Most suggested end-of-life pathways involve the disposal of the material by dissolution in water or industrial composting, both of which require production of new, virgin plastic to replace them. It is therefore difficult to see how a large scale switch to these hot water-soluble bags could contribute significantly to reducing the environmental impact of single-use plastics. Moreover, while the PVA used to make these bags is considered’marine-safe’ in some contexts, it is also hard to see how the bags would actually dissolve or degrade in marine environments in realistic conditions.
