A SEALED PAPER CARTON TO PROTECT CEREALS. 7 
not been labeled. The looseness of this end caused a break in the 
label, which, of course, ruined the seal of the package. Care in the 
proper sealing of the ends of the carton before applying the label will 
remedy this defect. 
The extra cost of a sealed package over the ordinary one will vary 
with the labor or machinery available and the cost of materials. It 
has been estimated at 1 cent for a 2-pound package, but it is best 
determined by each miller for his particular locality. With right 
management the cost should not prove excessive, while the use of 
the well-made sealed package will minimize the chance of infestation. 
The improved appearance of such a package, also, renders it more 
attractive to the prospective buyer. 
PACKAGES OTHER THAN SEALED CARTONS. 
Other forms of packages have been suggested, the most promising 
one being a sealed paper bag placed inside of an ordinary carton.

Although this forms a barrier to insects which have crawled through 
the openings in the corners of the carton, it places them with little 
or no food firmly against a thin wall of paper through which they 
would be very likely to force their way. 
Furthermore, it was observed that the ends of the paper bags were 
not readily sealed; small openings were left in many cases. One 
firm using this package reported that about as many of this type 
were returned infested as of the old-style packages. 
Again, the small amount of cereal spilled between the bag and the 
carton is used by a larva, as shown in figure 8, and, in any event, 
the presence of insects on the top of the bag would be sufficient cause 
for the return of the package.
