LDPE Blown Film Resin MFI 2.0-4.6 | Co-extrusion Seal Layer with LLDPE

Product Description

Product Description

LDPE blown film resin MFI 2.0 for sealed bags, clothing dust cover, soft film

Product Introduction

MFI 2:

Versatile LDPE sealant resin engineered for high-performance co-extrusion film layer applications. This MFI 2.0 polyethylene offers exceptional LLDPE compatible adhesion and melt stability, making it an ideal flexible packaging resin for premium lidding films, pouches, and laminates requiring low-temperature sealing and superior processability.

MFI 0.3:

Premium LDPE heavy gauge film resin (MFI 0.3 polyethylene) engineered for high-performance pallet wrap resin and industrial liners. As a tough LLDPE skin layer in coextruded structures, it delivers exceptional puncture resistant film performance with superior cling force and load-holding capacity. Optimized for compatibility with MFI 1.0 linear resins to maximize output in heavy-duty blown film lines.
