Water Soluble Laundry Bags: Buyer's Guide

Water soluble laundry bags are made from PVA film and dissolve inside the wash, so soiled linen goes from hamper to washer without being opened or sorted. Every shift, hospital and hotel laundry teams skip that step entirely: the sealed bag goes straight into the machine with the load. For procurement teams comparing suppliers, the decision comes down to four things — solubility grade, size, thickness, and packing. This guide sets out the specifications UCLEAN supplies as a source factory, so you can match a bag to your wash program before requesting a quotation.

Three Solubility Grades for Every Wash Program

Water soluble laundry bags are not a single product. The PVA film is made in three dissolution grades, and matching the grade to your wash program keeps the bag intact during collection and transport, then fully dissolved in the machine:

• Cold water soluble — dissolves at 25°C and above, for standard hotel and facility laundry
• Medium temperature — dissolves at 45–60°C, for warm wash programs
• Hot water soluble — dissolves at 65–90°C, for hospital hot-water cycles

Red hamper liners used for contaminated hospital linen are produced in the hot-water-soluble grade. If your facility runs several wash programs, all three grades can be supplied alongside each other, so one supplier can cover cold, warm, and hot cycles.

Standard Sizes, Thickness and Packing

Three stock sizes cover most hampers, linen trolleys, and collection carts. Every size is produced in 25-micron PVA film and packed 25 pieces per pack, with a choice of folded or rolled cartons:

For buyers who need something beyond the stock program, custom sizes, colors, and printed logos are available. MOQ is 5,000 pieces, and the three regular sizes are kept in stock for faster dispatch. For non-soluble programs, the same factory line also covers PE and biodegradable laundry bags.

Before and After: A Safer Linen Workflow

The clearest way to see the value is to compare the same load handled the two ways:

For hospitals, nursing homes, and laboratories, this closed process supports the infection prevention and control priorities set out by the World Health Organization, because it removes most contact points between staff and soiled fabric. For hotels, the same convenience applies to stained or suspect linen — and the bags run in standard commercial washers, so no equipment change is needed.

What Buyers Ask Before Ordering

Can you provide samples? Yes — 2–3 stocked samples are free of charge, and you only cover the shipping fee. Custom logo samples carry a small nominal fee.

What is the production time? About 20 days after order confirmation. The three regular sizes are in stock, so repeat orders can dispatch sooner. Goods leave from Shanghai, Ningbo, Xiamen, Guangzhou, or Qingdao.

Which certificates do you hold? Our water soluble laundry bags are produced under ISO, CE, RoHS and FDA certification.

How are the bags packed for export? 25 pieces per pack, in folded cartons of 200 pieces or rolled cartons of 100 pieces, with custom labeling available on request.

UCLEAN runs a 16,000 m² factory with more than 10 years of export experience and 15 years of logo printing and design work. Beyond the stock sizes, bag dimensions, thickness, color, and printed logo can all be customized, with free design support included. Artwork works best as vector files (AI, CDR, or PDF); 300 DPI JPG or PNG files are also accepted.
