2. Core Product Advantages
Excellent Melt Fluidity for High-Speed Continuous Production
This resin has even melt flow and good plasticizing performance. It supports stable and continuous extrusion. It maintains uniform film thickness during production and avoids melt fracture and film breakage. It fits most mainstream blown film machines perfectly. It adapts to high-speed production lines to shorten production time and improve overall working efficiency.
High Gloss & High Clarity for Premium Appearance
This material features low haze and high gloss to produce highly transparent films. Fish eye defects are strictly controlled during production. The finished film has smooth surface and good printing performance. It satisfies both ordinary packaging and mid-to-high-end packaging demands. It can clearly display packaged goods and upgrade overall packaging appearance.
Outstanding Low-Temperature Toughness & Stable Mechanical Properties
It has balanced tensile strength and tear resistance with good ductility. The finished film can bear heavy load. It stays flexible without hardening or cracking under extremely cold conditions. The film resists impact damage and aging during long-term use. It fits both indoor and outdoor packaging scenarios with a low product damage rate.
Food-Grade Purity with Low Migration
The pellets are pure and odorless with low substance migration. It complies with standard food contact regulations. It can be directly used for food packaging and meets all hygienic requirements for food storage and fresh keeping.
Superior Chemical Stability for Wide Application
It has good resistance to acid, alkali, salt and alcohol solvents. It also has stable electrical insulation performance. The material will not degrade or crack after long-time contact with daily chemical products, keeping steady comprehensive performance in different usage environments.
Ready-to-Use with Slip & Antiblock Agents
Standard slip agent and antiblock agent are pre-added during factory production. Users can process the pellets directly without extra additives. It effectively prevents film blocking and roller sticking during film blowing processing.
3. Detailed Application Fields
Food Packaging: Frozen food packaging films, fresh-keeping bags, general food bags, snack packaging films, heat-seal layers for composite films, liquid food packaging films.
Agricultural Films: Greenhouse films, mulch films and agricultural covering films. It has high light transmittance, good tensile strength and excellent low temperature resistance to adapt to various farmland environments.
Daily & Logistics Packaging: Supermarket shopping bags, household garbage bags, courier bags, logistics inner films, heavy-duty packaging bags.
Industrial Films: Heat shrinkable films, cast films, industrial protective films, multi-layer composite inner films.
We can provide customized modification services including toughening treatment and weather resistance enhancement according to customer demands to expand more application ranges.
4. Blown Film Processing Guidelines
Recommended Process Parameters
Barrel temperature: 160–190°C. Increase temperature gradually from feed inlet to die head.
Die head temperature: 180–200°C. Adjust temperature slightly based on actual film thickness.
Blow-up Ratio: 2.5–3.5
Drying requirement: No drying is required for normally stored pellets. Dry damp pellets at 60–70°C for 1 hour.
Blending suggestion: It can be blended with LDPE and LLDPE materials. Blending helps improve film toughness and processing performance, and control production costs reasonably.

6. Frequently Asked Questions
Q1: Do I need to add extra slip agent or antiblock agent during production?
A: No extra additives are needed. This resin is pre-mixed with standard slip agent and antiblock agent at factory. It can be used directly for production lines to avoid film blocking and roller sticking effectively.
Q2: Can Shenhua 2426H be used for frozen food packaging?
A: Yes. Its brittleness temperature is below -70°C. It keeps good flexibility and will not crack at -60°C. With food contact compliance, it is very suitable for frozen food packaging films and fresh-keeping bags.
Q3: Can this resin be blended with other polyethylene materials?
A: Yes. It has good compatibility with LDPE and LLDPE. Proper blending can optimize film toughness and processing performance, and control production costs well.
Q4: What should we do if the pellets get damp?
A: Normally stored pellets need no drying. Dry damp pellets at 60–70°C for 1 hour if moisture is absorbed.
