How do soluble bags work?

October 09, 2023

An eco-friendly and hygienic way to reduce employee interaction with tainted laundry is to use water-soluble bags. They are frequently used to separate, move, and launder filthy garments, uniforms, and bed linens in industrial and healthcare environments.


The color weighing workflow is optimized with water-soluble dyeing bags


They enable precise dosing of the dye according to the recipe by inserting the bag straight over the preparation tank. This will happen without changing the content or leaving behind residues. The water-soluble bags are the ideal addition to a chemical weighing system, making it easier to store heavy dyes and prepare more colors in the future. Furthermore, it enhances workplace ergonomics by sparing the operator from prolonged chemical exposure. In addition to bespoke orders, we keep a variety of sizes in stock. Many water-soluble packaging manufacturers are present which look after these biodegradable materials.


Fully Soluble Laundry Bags/Fully Water Soluble Bags


The "DissolvaBle" water-based laundry bags are compostable, non-toxic, and break down in water, leaving behind only innocuous materials that have no negative effects on the environment when disposed of. These dissolving bags are currently in daily use in NHS hospitals across the globe after undergoing rigorous testing and approval from the National Health Service. The water-soluble laundry bags that dissolve are skillfully engineered to meet the growing need for affordable solutions that ensure infection control and secure containment of contaminated laundry during its extraction from beds and bathrooms and transportation to the washing machine.


Water-soluble laundry bags made by dissolving are:

1. Superior, dependable, robust, and extremely resistant to punctures.

2. 100% soluble in water and biodegradable in accordance with NHS Executive requirements, HSG (95) 18: Institutional Washing Procedures for Handling Spent and Infected Linen.

3. To be utilized in industrial cleaning procedures and industrial washing machines.


How do laundry bags that dissolve in water operate?


Healthcare personnel can quickly and easily remove and bag contaminated, soiled, and infected linen and towels with our dissolvable solution. The washable bags are sealed, so contact with the contaminated fabric is avoided until the clean laundry is taken out of the washing machine and washed while still in the bag. This makes transpiration possible and eliminates the chance of cross-contamination for laundry staff and medical teams that are participating in the cleaning procedure. The alginate bags, which are also known as laundry bags, entirely disappear throughout the washing process, and any materials that are still present in the wastewater are totally safe for the environment. These bags are commonly known as "red laundry bags'' because of their red tint, but we can also provide them with an orange tint or as transparent laundry containers that have or lack a red strip to support your infection control organizational procedures.


Strip laundry bags soluble in cold water


Additionally, we have laundry bags that dissolve in cold water and contain a water-soluble strip that melts at 20 degrees C. Since our dissolving strip bags don't need to be opened before washing and keep fluid from escaping during transit, they offer exactly the same infection management and protection as our red laundry bags. The remnants of the bag are taken out at the conclusion of the wash, when a strip that makes up the bag dissolves in the washing and releases the linen.


Production of Water-Soluble Laundry Bags


As the foremost authorities in the field of certified water-soluble laundry containers, we guarantee the maintenance of the highest standards of quality control and customer care throughout the production process, giving each and every one of our clients the greatest possible experience. In order to provide the best laundry bags possible, we, as the NHS's polythene supplier, monitor all of our procedures, quality assurance tests, and raw materials.


Alginate laundry containers are a vital tool for assisted living facilities as well, helping to prevent infections and safeguard caregivers by offering a basic, clean way to store items until they are washed. Our water-soluble bags can be utilized for lining transportation containers, guaranteeing the safety of any handlers during the laundry process. They disintegrate at 65 degrees Celsius. Our laundry bags are produced from a PVA (polyvinyl alcohol) film, which is completely non-toxic and has no negative environmental effects.


Working and methodology


The wet method, which involves dissolving the polyvinyl alcohol components in water, mixing them into a paste, and then coating the equipment mold's surface before it dries into a film, is currently the primary method used to produce water-soluble films. However, this method has drawbacks, including a significant expenditure of energy, low efficiency, a limited application range, high cost, and few economic benefits. The P-PVA will be converted into film using the existing blown film apparatus via thermoplastic processing, also referred to as the "dry method." This process yields water-soluble films, which are a very promising new material due to their low energy consumption, excellent effectiveness, broad application range, low cost, and significant economic benefits. Water-soluble packaging manufacturers use these techniques to form plastic bag films. There are a total of three types of water-soluble films that are utilized for polymer packing, based on market demand:


Rapidly soluble resin (XQ-S series)


It is made using a modification technique using polyvinyl alcohol (PVA) and has a polymerization degree of at least 2600 and an alcohol solubility of at least 88. Once the film is created, it is placed with the boxed items in water at the same temperature and dissolves rapidly.


Slow-dissolving resin (XQ-H series)


allows for the expansion of the product's application range by causing the water solubility to decrease after film formation and to rise to the proper temperature when the degree of polymerization and alcohol solubility are mediated.


Water-soluble resin with a high melting point (XQ-G series)


Water-soluble resin at high temperatures (XQ-G series), which, after film formation, can be soluble in water at temperatures higher than 55°C by modifying the manufacturing technique, is intractable in water at ambient temperature. Whether utilized at typical temperatures and humid settings, this product can prevent swelling or moisture absorption and be employed in a wider range of packaging applications.
