As of my last there were several manufacturers that produced water-soluble bags. These bags are often used in various applications, including laundry, medical waste disposal, and more. To find water-soluble bag manufacturers, you can use the same general approaches I mentioned earlier:

1. Online Search: Conduct an online search using keywords like "water-soluble bag manufacturers" or "dissolvable bag suppliers." This should help you find companies that specialize in this type of packaging.
2. Trade Shows and Exhibitions: Attend water soluble bag manufacturers trade shows and exhibitions related to packaging and environmental solutions. Manufacturers of water-soluble bags often showcase their products at such events.
3. Industry Associations: Contact industry associations related to packaging, environmental sustainability, or specific sectors that use water-soluble bags. These associations may have directories or lists of manufacturers.
4. B2B Marketplaces: Websites like Alibaba, Thomasnet, or Global Sources can provide listings of manufacturers and suppliers of water-soluble bags.
5. Direct Inquiries: Reach out to companies that use water-soluble bags in your desired application and inquire about their suppliers. They may be able to recommend manufacturers.

When you contact potential manufacturers, be sure to ask about their product specifications, certifications, minimum order quantities, pricing, and any customizations they can provide. Additionally, verify the current information, as the industry may have evolved since my last knowledge update.

Keep in mind that the availability of manufacturers and the quality of their products can vary, so it's important to thoroughly research and assess your options before making a decision.
