we are corrugated box manufacturer located at paonta sahib, himachal pradesh. we are manufacturing various two main products named corrugated boxes & corrugated sheets. you can have a look at our product portfolio .

coming to corrugated boxes, also known as, corrugated cardboard cartons, we are manufacturing packaging boxes as per customers requirements. but broadly, it can be bunched into certain types of corrugated boxes. those are 3 ply corrugated box, 5 ply corrugated box, 7 ply corrugated box ,die cut box, custom printed corrugated box, white boxes and multi depth box.

corrugated fiberboard or "combined board" has two main components: the liner and the medium. both are made of a special kind of heavy paper called containerboard. linerboard is the flat material, typically on the outer surfaces of the board but also on the inside for some structures, that adheres to the medium. medium is the paper that is formed into arches or flutes on the single facer and glued between the linerboard facings.

architects have known for thousands of years that an arch with the proper curve is the strongest way to span a given space. the inventors of corrugated fiberboard applied this same principle to paper when they put arches in the corrugated medium. these arches are known as flutes and, when anchored to the linerboard with an adhesive, they resist bending and pressure from all directions.

when a piece of combined board is placed on its end, the arches form rigid columns, capable of supporting a great deal of weight. the flutes act to keep the linerboard sheets separated, maximizing the bending rigidity of the board. when pressure is applied to the side of the board, the space in between the flutes acts as a cushion to protect the container's contents. the flutes also serve as an insulator, providing some product protection from sudden temperature changes. at the same time, the vertical linerboard provides additional strength and protects the flutes from damage.

flutes come in several basic designations. flutes with the same designation have similar size, but may have various flute profiles and number of flutes per foot within a given designation:

a flute was the original flute profile for corrugated board. it has about 33 flutes per foot.

b flute was then developed for canned goods that were self-supporting, and so did not require boxes that supported much load. it has about 47 flutes per foot.

c flute was next developed as an all-purpose flute, and it has about 38 flutes per foot.

e flute was the next successful flute profile, and it has about 90 flutes per foot.

f flute was developed for small folding carton type boxes. it has about 125 flutes per foot.

in recent years not only has there been a proliferation of flute profiles, but there has been increase in the
