To customers requirement, when drink hot water,coffee,and hot noodle,,,,only one wall paper cups,paper bowls are become very hot,inorder not to hurt the hand by hot drinks,so over the inner cups,we make a jacket to protect hand from harm.

Double wall paper cups have two layers(walls), the inner is the white cup(bowl), the out layer is the jacket with printing.So to make double wall paper cups need two type of machines,
1.to make the inner cup(bowl),use LBZ-L or LBZ-LI or LBZ-LII or LBZ-LIII paper cup(bowl) forming machine,
2.to make the out jacket, use the LBZ-A Paper Bowl Over Coating Machine,

Note, the jacket forming machine, we name it as LBZ-A Paper Bowl Over-coating Machine, it can produce the jakcet for cups and bowl, mainly depend on the molds.

The out Jacket,have two types,
A . Direct type, the out jacket just direct agglutinating over the inner cup by mucilage(gluewater).

B . Hollow type, between the out jacket and the inner cup, there are space,that mean it is hollow.

To make the direct or hollow jacket in the LBZ-A Paper Bowl Over-coating Machine, the machine is only a little different.
To make the hollow type, at the bottom of the jacket is curling as the white-cup's bottom.
