Problems solved by technology

The most common consumer complaint for water-soluble pouches is linked to unwanted pouch dissolution when accidentally exposed to small amounts of water, such as when water gets inside the outer packaging in which the pouches are sold and stored after purchase, from wet hands, high humidity, leaking sinks or pipes during storage.
This may cause the water-soluble pouches to leak

examples

[0055]A nano-sized (approx. 0.1 micron size) PTFE coating, supplied by Shamrock Technologies (Newark, N.J.) under the tradename NanoFlon W50C, is dispersed in water (15% NanoFlon W50C, 85% water) and printed onto a standard 3 mil polyvinyl alcohol-based water-soluble substrate supplied by Monosol. The nano-particles are small enough to not refract the incident light, hence the coated water-soluble substrate has the same appearance than the uncoated water-soluble substrate (completely clear, non-hazy).

Droplet Test Method

[0056]To determine if a substrate is resistant to accidental water contact a proplet Test method has been developed. In this test, a pouch (approx. 2″×2″) is formed in a cavity and a droplet of 0.2 ml of room temperature water is added to the formed side of the pouch. The formed side is the stressed case for this test since the film is thinned during cavity formation. A stopwatch is started as soon as the water contacts the pouch and the time when significant film def...

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 60 / 818,692, filed Jul. 5, 2006, the disclosure of which is incorporated by reference.FIELD OF THE INVENTION[0002]This invention relates to an article comprising a product composition and a container having a water-soluble portion and an indicator. The invention also relates to packages comprising the article.BACKGROUND OF THE INVENTION[0003]Water-soluble substrates are gaining wider acceptance for use as packaging materials such as containers. These containers comprise a product composition which is to be released when the container is immersed in an aqueous solution. Examples of such containers are sachets and pouches, and often, they comprise a unit-dose of a product composition.[0004]The most common consumer complaint for water-soluble pouches is linked to unwanted pouch dissolution when accidentally exposed to small amounts of water, such as when water gets in...
