Frequently Asked Questions
Does a dissolvable singlet bag need to be removed before washing?+

No. A dissolvable singlet bag is designed to go straight into the washing machine with the soiled contents sealed inside. The PVOH film dissolves completely at 60°C during the normal wash cycle, so staff never handle contaminated linen at the point of loading. This touch-free, water-soluble process is why hospitals, aged care facilities, and commercial laundries choose dissolvable singlet bags for infection control and safer linen handling.

What temperature does a PVOH dissolvable singlet bag dissolve at?+

A PVOH dissolvable singlet bag is engineered to dissolve in hot water at 60°C and breaks down within the wash cycle as the load is agitated in the machine. It stays fully intact at room temperature and in cold water, so the bag holds its shape during collection, transport, and loading. Only sustained hot water triggers dissolution, which gives laundry staff full control over when the bag releases its contents. Ambient humidity and brief contact with damp linen will not break it down.

What can you put in a dissolvable laundry singlet bag?+

Dissolvable singlet bags are made for soiled, contaminated, and infectious linen in healthcare, aged care, and commercial laundry settings. Load items such as patient bed linen, towels, gowns, and uniforms, then seal the bag and place it directly into the washing machine. Keeping contaminated linen sealed until it reaches the machine reduces cross-contamination risk and limits staff exposure during collection and transport. The large 550 x 300mm bag with a 190mm gusset suits bulk and heavily soiled linen loads.

Is a dissolvable singlet bag environmentally safe and residue-free?+

Yes. PVOH (polyvinyl alcohol) dissolves completely into water and leaves no microplastics and no plastic residue behind. The film is fully biodegradable and marine safe, so the dissolvable singlet bag removes single-use laundry plastic from the waste stream and supports facility sustainability and waste-reduction targets. It is a practical, eco-friendly replacement for conventional plastic laundry bags.

What is the shelf life of a PVOH dissolvable singlet bag?+

Stored correctly in a cool, dry place away from moisture and direct sunlight, PVOH dissolvable singlet bags have a shelf life of 5 years or more. PVOH shares the same long-term storage characteristics as conventional LDPE and HDPE film, so the bag does not degrade with age and stays stable until you are ready to use it. Only sustained hot water above 60°C will dissolve the bag, not the ambient humidity present in normal warehouse or storeroom storage.
