Polyethylene (PE) is the most widely used polymer material worldwide. With excellent toughness, moisture barrier property and heat-seal performance, it maintains strong market demand in food packaging, industrial stretch film, agricultural film and e-commerce protective packaging. PE has three major mainstream grades: HDPE (high-density polyethylene), LDPE (low-density polyethylene) and LLDPE (linear low-density polyethylene). Different grades can be customized to adjust transparency, puncture resistance and tensile property, suitable for film blowing processing with stable roll performance for high-speed packaging lines.

Driven by global circular packaging regulations, all-PE single-material structure has become a hot topic in the industry. Traditional PET/PE multi-layer laminates are hard to separate and recycle, while pure PE film requires no layer splitting for easier recycling. Many brand owners are switching to single-material PE bags for snacks, frozen food and pet food packaging. Meanwhile, recycled rPE technology matures, enabling addition of post-consumer recycled resin without sacrificing mechanical performance, lowering carbon footprint and meeting overseas sustainable procurement requirements.

PE film features outstanding low-temperature resistance and does not easily turn brittle in cold environments, ideal for cold chain, fresh produce and bulk powder moisture-proof liners. Formula modification can deliver slip, anti-blocking and anti-static functions. Global PE film market keeps steady growth, supported by downstream food processing, cross-border e-commerce and agriculture sectors. Film manufacturers keep optimizing down-gauging technology to cut material consumption while retaining strength, helping customers control packaging costs and balance economic and environmental benefits.

For export business, PE film boasts consistent quality and flexible specifications, widely supplied to packaging converters globally. Custom width, thickness and roll weight are available. Corona treatment can be applied to improve printing adhesion, making it an irreplaceable base material in flexible packaging.
