HDPE Film Opalene

Whatsapp Order

HDPE Film Opalene is a high-density polyethylene film grade resin specially engineered for producing thin, flexible, and high-strength films. It is designed for blown film extrusion processes, delivering excellent mechanical properties, superior clarity (opal/opalene finish), and consistent gauge control. This resin offers high tensile strength, good puncture resistance, and excellent moisture barrier properties, making it ideal for packaging applications requiring durability and flexibility. Its balanced processing characteristics enable fast extrusion rates and uniform film thickness.

Description

HDPE Film Opalene

Primary Uses 

  1. Packaging Industry
  • Used extensively in flexible packaging films for food products such as snack wrappers, frozen food bags, and fresh produce packaging.
  • Suitable for shopping bags, carrier bags, and refuse sacks requiring high tear resistance and durability.
  • Employed in shrink films and stretch wraps for palletizing and bundling products.
  • Used in industrial packaging films for protection and moisture barrier in storage and transport.
  1. Agricultural Films
  • Production of mulch films and greenhouse covers providing protection while allowing light diffusion (opal finish).
  • Used in silage films for forage preservation due to moisture and oxygen barrier properties.
  1. Medical and Hygiene Products
  • Used in protective covers, medical packaging films, and hygiene product wraps where sterility and barrier protection are essential.
  1. Consumer Goods
  • Production of garbage bags, liners, and protective films for household and commercial use.
  • Used in laminated films for flexible packaging combining mechanical strength and printability.

 

Secondary Uses 

  1. Industrial Applications
  • Films for industrial liners and protective sheets in construction and manufacturing.
  • Used as vapor barriers in building insulation and packaging.
  1. Printing & Lamination
  • Acts as a substrate for lamination with other polymers or paper to enhance packaging aesthetics and performance.
  1. Recycling Applications
  • Accepted in film recycling streams and can be reprocessed into various low-to-medium-end film products.
