Can the bag be placed directly into the washing machine?

In traditional hotel linen washing processes, reusable fabric laundry bags have long been used for collecting and transporting soiled linens. However, from a microbiology and infection control perspective, these bags themselves can become a medium for cross-contamination of bacteria and pollutants.

An innovative solution—"water-soluble laundry bags"—is changing this paradigm.

Why can water-soluble laundry bags be placed directly into the washing machine?

Water-soluble laundry bags are not ordinary plastic bags. These bags can be loaded directly into industrial washing machines. Under the set hot water temperature (typically 60°C-80°C) and mechanical action, the bag material dissolves rapidly at the beginning of the wash cycle, allowing the enclosed linens to come into direct contact with the wash liquor for effective cleaning. The bag material dissolves completely in the wash water, leaving no solid residues that require sorting or handling. Its main component, polyvinyl alcohol (PVA), is ultimately biodegradable.

How does the bag dissolve in water?

The key to this functionality lies in the water-soluble polymer material used for the bag, typically polyvinyl alcohol (PVA). This material possesses the following characteristics:

What can we achieve with water-soluble bags?

1、For hotels, especially premium and wellness-oriented brands, linen hygiene is a fundamental expectation. This commitment provides guests with a higher, traceable standard of hygiene assurance.

2、It eliminates the tedious steps of sorting, cleaning, and separately washing and disinfecting soiled laundry bags, thereby reducing both the frequency and extent of laundry staff's exposure to potential contaminants. This approach aligns with the evolving standards in occupational health and safety management.

3、This solution goes beyond mere substitution of disposable plastic bags by stopping plastic waste generation at the source. The bag’s “self-eliminating” feature turns a routine process into a material proof of the hotel's commitment to circular practices and its broader ESG goals.

Our Uclean team innovatively applies this technology to the R&D and manufacturing of water-soluble laundry bags. With our independently developed large-scale, multi-functional bag-making and printing equipment, we begin with the core formulation of water-soluble materials. We precisely control the dissolution temperature, rate, and dry-state strength, ensuring the product remains stable and reliable during storage and transport, yet dissolves quickly and completely in hot water.

Whether for linen handling in premium hotels, fabric laundering in medical and wellness institutions, or other commercial scenarios with strict hygiene segregation requirements, we are committed to assisting our clients in enhancing operational safety and process efficiency with our reliable and innovative water-soluble products. We aim to contribute substantively to raising industry hygiene standards.
