Is ExxonMobil 1002BU the Right Choice for Your Blown Film Line?

Your film tears too easily. Your bubble wobbles on the line. You blame the machine, but the resin may be the real problem behind your poor results.

ExxonMobil 1002BU is a butene-based linear low-density polyethylene made for blown film. It gives high gloss, strong draw down, and good tensile and toughness values. That combination is why many converters still keep it on their approved list.

I have worked with many polyethylene grades over the years. Some names sound similar on paper, but they behave very differently on a real production line. This article looks at three questions I hear most from processors and buyers. Stay with me, because the answer may change how you pick your next resin.

Which Is Better, ExxonMobil 1002BU or Yanchang 5010Y?

Buyers ask me this question every week. They want one clear winner. But the real answer is not that simple.

Neither grade wins in every case. ExxonMobil 1002BU offers strong film clarity and consistent processing. Yanchang 5010Y may cost less and suit simpler local supply chains. The right choice depends on your film goals.

What actually separates these two grades

I do not compare grade names first. I compare how each resin runs on my line. ExxonMobil 1002BU is a butene LLDPE. It gives high gloss and strong draw down during blown film production. Films from this grade also show good tensile strength and toughness. This makes it a steady choice when your customer expects consistent film quality, batch after batch.

Yanchang 5010Y is a domestic option. Many processors choose it for cost reasons or supply stability within China. It can perform well in simpler film structures where extreme optical clarity is not the main goal.

I do not pick a winner from this table alone. I match the table to the job in front of me.

What Is ExxonMobil 1002BU Film?

Some buyers ask me this question without knowing that the grade already has a clear role in the film world.

ExxonMobil 1002BU film refers to blown film made from this butene LLDPE resin. The film shows high gloss, good drawdown, and strong tensile and toughness properties, which suit many packaging and industrial film needs.

Why film makers choose this grade

I look at three things when I judge a film resin: how it processes, how it looks, and how it performs after conversion. ExxonMobil 1002BU handles well during blown film extrusion. It allows good drawdown, so a converter can stretch the film thinner without breaking the bubble. This helps reduce material cost per roll.

The film also shows high gloss. Brand owners often want this look on the shelf. Beyond appearance, the film carries solid tensile strength and toughness. This matters when a bag or wrap must survive handling, stacking, or transport.

I often tell buyers that a clear material comparison, like the kind Chengnuo puts together for polyethylene grades, helps them line up these traits side by side before they commit to a trial run. This saves time and avoids costly line trials on the wrong grade.

Where Is ExxonMobil 1002BU Used?

Buyers often think one resin only fits one product. That is rarely true in real production.

ExxonMobil 1002BU is used across packaging film, agricultural film, and composite film structures. Its blend of gloss, strength, and processability lets converters use it alone or as part of a multi-layer structure.

Three common end uses

Packaging film is the most common use. Food bags, retail wraps, and general packaging need a film that looks clean and holds up during transport. This grade supports that need well, and its gloss level often meets brand-facing packaging standards without extra additives.

Agricultural film is another common area. Growers need film that resists tearing during installation and daily field use. The toughness in this resin supports that demand, though the final formulation still depends on additive packages for proper UV protection.

Composite film is the third major use. Many converters blend this resin with other layers to balance cost, strength, and barrier needs. In my experience, this flexibility is one reason processors keep this grade on their approved list even as new alternatives enter the market.

Conclusion

Choosing between resins is not about picking a single winner. It is about matching material behavior to your film’s real job.
