used in cosmetics, alcohol and food packaging.
Automatic lock bottom:-In automatic lock bottom type cartons, the body and
the bottom of the box can be folded into a flat plate shape, and the bottom of
the box can be automatically restored to the sealing status when the box is
stretched. This structure is complex and the cost is higher compared to other
boxes.
Tray style boxes:- Many tray style custom boxes also include covers or lid
components hinge-connected to one or more of the upper edges of the side or
end panels.
Seal End:- The seal end box is typically erected,

retail boxes.

other finishes that cover all of the outer side and edges. Cosmetics, candy,
jewellery, and other high end products that need luxury impression uses this

Packaging Die


Once a packaging structure and material are determined, a designer usually
receives a digital file of the packaging die from the client. The die is the blue
print of the structure or design layout and provides the exact dimensions and
product specifications. Bleed requirements and gluing specifications are
included in a two dimensional drawing to which a designer can apply brand
informations and graphics using computer software.
A die prepared for a packaging job has two parts. First is the preparation of
cutting and creasing rules which are preapred according to the size and design
of the job. Cutting and creasing rules are made of flexible steel. One edge of
the cutting rule is sharp and the other edge is blunt or thick. Both sides of the
creasing rules are blunt or thick. These rules are cut and bent into circles or
triangles or semi circles according to the size and design of the job.
