1. Green Revolution of Packaging - DN-90 Quick-Drying Starch
Adhesive
Confusing SMT Adhesives Market
With the development of market economy, China's small and medium-sized cardboard box
factory is everywhere, due to the relevant departments for a long time is not clearly sodium
silicate binder materials, cannot be used on the domestic packaging carton, the carton
standard adhesives do not clearly defined. Currently, it is popular on the market a "the carton
treasure", "starch glue, its prices are less than ideal performance, cause confusion to the
market, allowing users to select glue caused psychological barriers, for many small carton
factory crude the easy way, so the use is more than 100 years of traditional products sodium
silicate carton adhesive material, not knowing that there are many drawbacks to do with
sodium silicate binder, experts called to reiterate carton production should be eliminated
sodium silicate, and requires a Starch smt adhesive.
Drawbacks of the Sodium Silicate Adhesive
Sodium silicate is an aqueous solution of sodium silicate, is a strong base, weak acid salt,
showed a strong alkaline, the free base is 6% to 7%. The sodium silicate is able to penetrate
the carton surface, corrosion contents, does not meet the packaging requirements of food
hygiene, and foreign trade. In a humid environment, the sodium silicate absorbent
deliquescence, loss of adhesion, carton paper softened and deliquescence efflorescence,
affecting printed effect help cartons appearance. As we all know, the use of sodium silicate,
as an adhesive material cartons is hygroscopic, toxic, endangering human health and
ecological environment seriously affect the quality of packaging products and merchandise
sales, our packaging solved cut key issues, the paper and packaging industry tilted the
period of waiting for a new generation of adhesives speedy advent! Developed capitalist
countries in the 1950s are out of the sodium silicate in 1984, China began to limit and prohibit
the use of sodium silicate in the export and food packaging.
New Multi-functional Starch Adhesive
In May 1991, the State Economic and Trade Commission, Bureau of Technical Supervision,
the Ministry of Foreign Trade again noticed "disabled since 1992 all packaging plant sodium
silicate adhesive material". But what suffers is that unable to find a substitute. And some
foreigners even ridiculed: Chinese have the first class products, but the packaging is not
inflow, such as the Heat Sink Paste. Especially in the current paper packaging industry

2. trends, all require the use of green packaging, so as to protect the environment, and in
particular the accession to the WTO will be higher on the packaging requirements of
environmental protection. There should be a new generation of patented products in order to
meet the requirements of the times and the binder demand and trends, so the DN-90 series
multi-functional starch adhesives came into being, it is a new type of solid powder adhesive
material as the main raw material.
