LDPE Resin Up Again: What It Means for Courier Bags and Bubble Wrap Costs
LDPE resin prices rose again in October 2026, which lifts the cost of plastic courier bags, poly mailers and bubble wrap. Kraft paper is up too, about 25 to 30 percent since August. So plastic and paper packaging inputs are climbing together, not one instead of the other. This is market data, not a Vikrama price change.
What happened to LDPE resin prices?
Low-density polyethylene, the LDPE and LLDPE film that courier bags, poly mailers and bubble wrap are made from, moved up again in October 2026. The Plastemart polymer price list shows LDPE prices rising by Rs 3,000 per tonne in the EC and IM grades, revised on both 10 October and 17 October 2026, while LLDPE rolled over in the same period. An earlier LD EC grade rise of Rs 3,000 per tonne had already landed on 13 August 2026.
| Grade | Move | Effective |
|---|---|---|
| LDPE, EC and IM grades | Up Rs 3,000 per tonne | 17 Oct 2026 |
| LDPE, EC and IM grades | Up Rs 3,000 per tonne | 10 Oct 2026 |
| LLDPE, all grades | Rolled over | Oct 2026 |
| LDPE, LD EC grade | Up Rs 3,000 per tonne | 13 Aug 2026 |
These are producer list revisions for specific grades, not a single market price, so the exact rate your supplier charges depends on the grade and the deal. The direction, though, is clear: the film grades used for flexible packaging have been revised upward through the autumn, not down.
Paper is rising alongside plastic
The point for a packaging buyer is that the obvious alternative is moving the same way. Our own Kraft Ledger reported kraft paper up about 25 to 30 percent since August 2026, citing the Uttar Pradesh Corrugated Box Manufacturers Association on 28 September 2026. So this is not a case of swapping a dearer material for a cheaper one: both the paper in a corrugated box and the plastic in a courier bag or bubble wrap are under upward cost pressure at the same time.
Paper and plastic packaging inputs are climbing together, so switching material is not a way to dodge the rise.
What this means for your packaging cost
With both paper and plastic inputs rising, the saving now comes from using less of each, not from switching between them. Right-size the box so there is less board and less void to fill, plan runs rather than buying in a rush, and reach for a corrugated insert or partition instead of loose plastic fill where the product allows. Each of those cuts material at a time when every material is dearer.
To be clear, this is market data, not a Vikrama price change. We are reporting what the resin and paper markets did, not announcing a move of our own. Your exact box figure still comes from the calculator and a human confirmation, against the day's rate.
