Paper Packaging Manufacturers in India
Paper packaging is one material in three constructions. Corrugated board is a fluted sheet glued between flat liners, built to take load. A mono carton is a single sheet of board, printed, die-cut and folded, built to be looked at. A paper tube is paper wound in a spiral and capped at both ends. Paper bags and kraft paper rolls belong to the same group and are not yet listed; an RFQ can still describe them. Buyers arrive here for two reasons, strength per rupee and replacing plastic, and both come down to reading the specification: fibre, weight, construction and coating. The numbers on a paper quote are easy to misread, and the most quoted one, GSM, says the least about strength.
Inside paper packaging
Paper Bags, Kraft Paper Rolls are also part of this group and are not yet listed on Kypson. An RFQ can still describe them — the requirement reaches our sourcing team either way.
How to read a paper specification
GSM is weight per square metre, nothing more. On a corrugated box it is quoted per layer, typically 150 to 200 for the liners and 100 to 150 for the fluting, and strength comes from how those layers are built up: three, five or seven ply, and the flute profile between them. The form's own labels are a fair summary: A flute for cushioning, B for stacking, C as the balance, E thin enough for retail print, with BC and BE as the common double-wall pairs. Strength itself is stated as bursting factor, from 5 to 16 BF on the form, or as edge crush, and the form is blunt that edge crush predicts stacking better. Carton board is graded instead: SBS is virgin and white throughout, FBB has a mechanical-pulp middle that makes it stiff for its weight, duplex has a grey recycled back. Tubes are wound from two to five plies of 250 to 350 GSM paper to a wall of 1.5 to 3 millimetres, and the form wants 2.5 millimetres and four ply before it trusts a heavy stack.
Virgin, recycled, certified: what the claims mean
The corrugated form asks whether recycled content is allowed and offers a third answer beyond yes and no: fluting only. That is the sensible default. Virgin kraft liners carry the strength, recycled fluting carries the saving, and the form's note on all-virgin board is simply that it is stronger and costs more. Certification is a separate question. Asking for FSC paper is not the same as printing the FSC mark: the mark may only be used by a converter that holds its own chain-of-custody certificate, so ask for the certificate code with the quote, not after the artwork. Recyclability depends on what is added to the paper. Gloss, matte and soft-touch lamination are plastic films bonded to the board; an aqueous coating is not. Inside a tube, a greaseproof or kraft liner keeps the pack paper, while a foil laminate or PE coating adds real barrier and turns it into a composite. Neither choice is wrong. It should be made deliberately and stated on the RFQ.
Where paper fails, and what buyers get wrong
Moisture is the weakness. Board gives up a large part of its stacking strength in humid storage, which is why a box that passes in the factory can collapse in a monsoon warehouse. A water-resistant coating answers that, but the form notes it adds cost and is not needed for indoor-only use, so say where the goods will actually sit. The second mistake is specifying GSM and nothing else, then comparing quotes that differ in ply, flute and bursting factor as if they were the same box. The third is weight: above 20 kilograms the form wants five ply at minimum with stitched joints, and above 15 kilograms of stacking load a thicker tube. Exporters often ask a box maker for ISPM-15 treatment. That rule covers solid wood, the pallet and the crate, not corrugated board; what an export box needs is heavier kraft and a stated stacking height. Last, print: offset needs a plate per colour, around ₹3,000 to ₹8,000 each, so short runs and many SKUs belong on digital.
Paper Packaging: common questions
Is a higher GSM box a stronger box?
Not necessarily. GSM is only the weight of each paper layer. Strength comes from ply, flute and the quality of the liners, and it is measured as bursting factor or edge crush. For stacked goods, specify edge crush and the number of layers in the stack; the form treats that as the better predictor.
SBS, FBB or duplex board for a carton?
SBS where the product is food, pharma or premium: virgin, white throughout, the best print surface. FBB where stiffness per rupee matters, as in larger cartons. Duplex, with its grey recycled back, for economy packs where the inside is never seen. The form lists all three, within a 250 to 400 GSM range.
Can paper replace my plastic pack?
For dry goods, often: a carton or a tube with a greaseproof or kraft liner stays a paper pack. For powders, oils and anything needing a real moisture or aroma barrier, the tube needs a foil or PE liner, which makes it a composite. For liquids, paper alone is not the answer. State the product and shelf life on the RFQ.
Are paper bags and kraft paper rolls listed?
Not yet. Paper bags and kraft paper rolls are part of this group and are not listed on Kypson today. An RFQ can still describe them and reaches the sourcing team.
