Additive Free Polymer LDPE Coil

Grade: Additive Free Polymer
Formula: LDPE
Form: Coil
Material: Low Density Polyethylene (LDPE)
CAS Number: 9002-88-4
Commodity: Polymers
Coil Width: 600mm
Structure: Biaxially Oriented
The Additive Free Polymer LDPE Coil is a coiled low-density polyethylene (LDPE) film that contains no additives. Available in 8 variations, these LDPE films come in a wide variety of thicknesses, widths, lengths, colors and surface finishes. With properties such as flexibility, strength, chemical resistance and electrical insulation, they’re used in applications including packaging, plastic bags, protective coatings, and electrical insulation. Their additive free nature makes them suitable for food packaging and other sensitive applications where purity is paramount.
