PE Resin Prices November 2026: Why Plastic Bag Costs Are Rising

Updated 4 November 2026. Polyethylene, the resin behind almost every plastic bag and roll of stretch film, has been getting more expensive since the summer. Brent crude is trading around $104–110 a barrel, naphtha in Asia and Europe is up more than 60% from its June low, and PE film prices in China have risen by up to 46% in four months. In India, the two largest producers raised film-grade prices again on 1 November. Here is what is driving the increase, what the numbers say, and how bag and film buyers can limit the impact.

The numbers behind the increase

Why polyethylene keeps rising

Oil and naphtha

Most Asian PE is made from naphtha, an oil product. Earlier this year, conflict in the Middle East disrupted tanker traffic through the Strait of Hormuz and pushed feedstock costs sharply higher. Oil has come down from its April peak but is still above $100, and OPEC+ decided on 1 November to keep December output targets unchanged, so no extra supply is coming soon. When naphtha rises 60% in a few months, resin producers pass most of it on.

Fewer crackers in Europe and North Asia

Around 11 million tonnes a year of olefin, polyolefin and vinyl capacity in Europe has been closed, idled or earmarked for closure since 2024. Japan and South Korea are also cutting older crackers. Less local supply means more competition for Middle Eastern and US resin, which supports prices everywhere.

What could slow it down

Chinese futures have softened at times, and demand for finished goods is not strong. If oil falls on a Middle East settlement, resin would follow within weeks. Nobody can promise that, so plan for prices to stay firm through the end of the year.

What this means for plastic bag and film prices

Resin is roughly two thirds to three quarters of the cost of a plain bag or a roll of stretch film, so a 10% move in resin shows up quickly in the price per kilogram. Printing, converting and packing costs change slowly. In practice:

• Quotes are valid for shorter periods. Most suppliers, us included, are quoting with a short validity and confirming the price when the order is placed.
• Plain, heavy items feel it most. Trash bags, pallet covers, PE sheeting and stretch film are almost all resin. Printed retail bags feel it less.
• Thinner can be as strong. A better resin blend, such as metallocene LLDPE in stretch film or HDPE instead of LDPE for produce rolls, often lets you cut thickness by a few microns with the same performance. That saves more than haggling over the price per kilo.
• Recycled content, where your market allows it. For trash bags, part recycled resin can offset some of the increase. We make recycled-content trash bags on request.
• Book ahead of Lunar New Year. Resin and freight usually tighten again in January. Confirming early-2027 volumes in November or December avoids paying both peaks.

Frequently asked questions

Why are plastic bag prices going up in late 2026?

Because polyethylene resin is going up. Oil above $100, naphtha up more than 60% since June and plant closures in Europe and North Asia have pushed PE film prices higher, by up to 46% in China over four months.

Will PE resin prices fall in early 2027?

Only if oil and naphtha fall. With OPEC+ holding output and Middle East risk still high, most buyers are planning for firm prices through Lunar New Year.

How can I reduce my packaging cost without lowering quality?

Review the specification first: thickness, resin blend and bag size. Small changes, such as a stronger blend at a lower thickness, usually save more than switching suppliers. Send us your current spec and we will suggest options.
