PE Film Introduction

1. Product Overview

Polyethylene (PE) film ranks as the most universal and cost-efficient substrate material across the global flexible packaging industry, manufactured by extruding polyethylene resin through blown film or cast film production lines. As a core heat-sealable packaging material, it fills a vital role in both single-layer independent packaging and multi-layer composite bag inner liners.

We specialize in three core PE variants: LDPE, HDPE and LLDPE, alongside a full lineup of modified functional PE films. Compared with BOPP, PET and other plastic substrates, PE films stand out for their exceptional low-temperature resistance, flexible texture, reliable heat-sealing performance and superior moisture barrier capacity. All raw materials we adopt are odor-free and eco-friendly, fully compliant with cross-border food contact standards to meet export demands of Southeast Asia, the Middle East, Europe, North America, Australia and South America. With 25 years of dedicated flexible film manufacturing and export experience, we tailor PE film solutions for packaging converters, brand owners and foreign trading enterprises of all sizes globally.

2. Classification & Distinctive Performance Characteristics

LDPE (Low Density Polyethylene) Film

LDPE film features soft texture, mild haze and outstanding hot tack heat sealing performance. Its flexible surface avoids scratching printed layers during lamination and bag-making, making it the top choice for composite inner sealing layers. It maintains stable sealing strength even at low heat temperatures, effectively preventing liquid and powder leakage.

Typical uses: Snack composite bag inner layer, daily chemical refill pouches, general dry food packaging, small retail sachets.

HDPE (High Density Polyethylene) Film

HDPE delivers high rigidity, excellent puncture resistance and moderate oil-blocking performance. Its dense molecular structure greatly reduces water vapor transmission rate, offering stronger protection against moisture and dust. The stiff texture enables thin-gauge heavy-duty packaging to cut overall material costs.

Typical uses: Heavy-duty industrial lining bags, supermarket shopping bags, grain & feed outer packaging, hardware moisture-proof wrappers.

LLDPE (Linear Low Density Polyethylene) Film

LLDPE integrates the flexibility of LDPE and the tensile strength of HDPE, with dramatically improved tear resistance and cold endurance. It will not crack or become brittle under sub-zero freezing environments, retaining intact mechanical properties during repeated stretching and extrusion.

Typical uses: Frozen food cold-chain packaging, pallet stretch wrapping film, bulk cargo transport sacks, agricultural fresh-keeping packaging.

Custom Functional PE Film Series

Beyond standard grades, we develop modified PE films with targeted additives to satisfy specialized industrial requirements:

• Anti-fog PE film: Avoids water mist condensation for fruit, vegetable and fresh meat packaging, keeping contents clearly visible
• Anti-static PE film: Eliminates static buildup, ideal for electronic component and circuit board packaging
• High-slip PE film: Smooth surface for high-speed automatic bagging machines, no film sticking or jamming
• Matte printed PE film: Low-gloss frosted surface for high-end brand packaging with premium visual texture
• UV-resistant agricultural PE film: Anti-ultraviolet aging for long-cycle mulch and crop covering

3. Core Competitive Advantages of Our Factory’s PE Films

3.1 Outstanding Physical Mechanical Properties

Our PE films undergo strict tensile, puncture and low-temperature drop testing. LLDPE products can withstand -40°C cold environments without cracking; all series feature strong elongation at break to resist extrusion damage during long-distance sea transportation, fully safeguarding packed goods.

3.2 Stable Barrier Function

Superior moisture insulation blocks water vapor penetration to extend product shelf life. Selected HDPE and modified composite PE formulas provide mild oil resistance, suitable for packaging oily snacks and daily chemical lotions. The dense film structure also shields contents from dust and minor external pollution.

3.3 Perfect Compatibility with Post-Production Processing

Uniform film thickness guarantees consistent heat-seal strength without weak sealing or pinholes. The surface corona treatment meets high-standard gravure printing requirements, presenting clear, non-fading patterns. It works seamlessly with dry lamination, extrusion lamination and fully automatic high-speed bag-making equipment, eliminating delamination, curling and production downtime issues.

3.4 Strict Export-Grade Safety & Environmental Compliance

We only utilize food-contact certified polyethylene resin without recycled inferior raw materials. All food-grade PE batches can provide complete test reports covering heavy metal migration, plasticizer limits and odor control, satisfying inspection standards for EU, US and Southeast Asian markets. PE material is fully recyclable, aligning with global low-carbon and eco-friendly packaging trends.

3.5 Full Customization Flexibility to Match Market Needs

We adjust film thickness, width, transparency and surface slip coefficient as per client specifications. Functional masterbatch can be added during production to achieve anti-fog, anti-static, anti-UV and other effects. We support customized printing, composite structures and roll specifications to fit regional market packaging habits and regulatory standards.

6. Common Customer FAQ

Q1: What are the key differences between PE, BOPP and PET film, and how do I choose?

PE is primarily used as the heat-sealable inner layer of composite bags with strong low-temperature resistance; BOPP boasts ultra-high transparency and printing effect for outer decorative layers; PET provides superior oxygen and oil barrier for high-end long-shelf-life food packaging. We will recommend matched multi-layer composite structures according to your packaging contents, storage conditions and budget.

Q2: Can you supply official food safety certification documents for customs clearance?

Yes. All food-grade PE films pass relevant food contact testing standards required by EU, USA, Southeast Asia and other regions, and we can provide complete inspection reports, MSDS and customs clearance documents for every batch of goods.

Q3: What is your minimum order quantity and production lead time?

Standard LDPE/HDPE/LLDPE stock models support small trial orders; customized functional modified PE films or printed products take 7–15 working days for mass production, depending on specifications.

Q4: Will PE film crack under long-distance low-temperature sea transportation?

Our LLDPE series is specially formulated for cold-chain transport, remaining intact at temperatures as low as -40°C. We can adjust raw material formulas to enhance cold resistance if your goods require long-term refrigerated shipping.

Q5: Is it possible to print brand logos and patterns on PE film rolls?

Absolutely. We support gravure printing on PE films with up to 9 color patterns, and can cooperate with you to develop exclusive packaging designs tailored to your brand positioning and local market preferences.
