CASE STUDY: ExxonMobil Signature Polymers Partners With Chengdu Boshikerui on Metallized Polyethylene Film With Simplified Lamination Structure and Superior Barrier Performance
- Published: August 28, 2025
WHO: ExxonMobil, one of the largest publicly traded international energy companies, uses technology and innovation to help meet the world's growing energy needs. The company recently launched its new ExxonMobil Signature Polymers portfolio brand, which focuses on delivering best-in-class service and partnerships within the polymers industry. ExxonMobil Signature Polymers unifies ExxonMobil's polyolefin products under a single brand, simplifying portfolio navigation and promoting enhanced collaboration across the value chain.
WHAT: To address long-standing challenges in metallized flexible packaging, ExxonMobil Signature Polymers partnered with Chengdu Boshikerui New Materials Co., Ltd (BSKR), Chengdu Fulinda New Materials Co., Ltd (FLD), and Qinglan New Materials Co., Ltd. Traditional vacuum metallized films rely on three-ply structures using PET, which can be incompatible with polyethylene, leading to poor adhesion, weak barrier performance, and high friction during processing.
To overcome these limitations, ExxonMobil applied its advanced polyethylene solutions to enable a more efficient two-ply film. In the coextruded PE sealant layer:
Exceed™ Tough+ m 0814 and Exceed™ Flow+ m 0516 high performance PE delivered mechanical strength and toughness, ensuring package integrity and high needle puncture resistance.
Exxtra™ Seal m 2012 enhanced performance polymers provided low-temperature sealability, critical for sealing performance.
Exceed™ Stiff+ m 0926 added structural stiffness, allowing downgauging without compromising processing efficiency or mechanical performance.
The result is a vacuum metallized polyethylene (VMPE) film laminated with BOPP, forming a BOPP//VMPE lamination structure. The solution can be applied to a wide range of food packaging requiring superior barrier properties. With the removal of PET content in the lamination, this new film has a 100% polyolefins (PO) structure.
