A NOVEL STICKER TO DETECT SPECIFIED MAXIMUM RANGE IN THE TEMPERATURE SENSITIVE PRODUCTS

The present invention comprises of a sticker to indicate the temperature by using van der Waals porous crystal (VPC) material which changes the color from VPC yellow (1) to VPC red (3) during chemical reaction with water (4). The VPC material is dip coated on the upper side of thin metal surface (2)...

Beschreibung
Zusammenfassung:	The present invention comprises of a sticker to indicate the temperature by using van der Waals porous crystal (VPC) material which changes the color from VPC yellow (1) to VPC red (3) during chemical reaction with water (4). The VPC material is dip coated on the upper side of thin metal surface (2) and dried at sun temperature and the lower side of the metal surface is attached with white thin doubled sided tape(5) which is pasted on temperature sensitive products item. The water is sprayed on the surface of crystal structure to cause chemical reaction with water and changes the color from yellow to red. The presence of red color in the crystal structure provides indication of the product items that are maintained at correct temperature. The products changes color from red to yellow within 10 minutes at room temperature.
