Food container having an inner protecting layer

Abstract

A food container includes: a container body made of paper, and having an inner surface defining a receiving space therein, and an outer surface opposite to the inner surface; and an inner protecting layer coated on the inner surface and made from a biodegradable coating composition including polybutylene succinate as a major component. The biodegradable coating composition further includes a minor component selected from polybutylene adipate/terephthalate, polylactic acid, and combinations thereof.

1 . A food container comprising:
 a container body made of paper, and having an inner surface defining a receiving space therein, and an outer surface opposite to said inner surface; and   an inner protecting layer coated on said inner surface and made from a first biodegradable coating composition including polybutylene succinate as a major component.   
     
     
         2 . The food container of  claim 1 , wherein said first biodegradable coating composition further includes a minor component selected from the group consisting of polybutylene adipate/terephthalate, polylactic acid, and combinations thereof. 
     
     
         3 . The food container of  claim 2 , wherein, based on a total weight of the first biodegradable coating composition, the major component is in an amount ranging from 90 wt % to 100 wt %, and the minor component is in an amount ranging from 0 wt % to 10 wt %. 
     
     
         4 . The food container of  claim 1 , further comprising an outer protecting layer that is coated on said outer surface and that is made from a second biodegradable coating composition including polybutylene succinate as a major component. 
     
     
         5 . The food container of  claim 4 , wherein said second biodegradable coating composition further includes a minor component selected from the group consisting of polybutylene adipate/terephthalate, polylactic acid, and combinations thereof. 
     
     
         6 . The food container of  claim 5 , wherein, based on a total weight of the second biodegradable coating composition, the major component of said second biodegradable coating composition is in an amount ranging from 90 wt % to 100 wt %, and the minor component of said second biodegradable coating composition is in an amount ranging from 0 wt % to 10 wt %.
