2.3 Thermal Resistance Performance Parameters
The Vicat softening point of HDPE 7000F is 124℃ to 125℃ for moderate heat resistance capacity.
Its melting temperature ranges from 125℃ to 131℃ to fit standard film blowing processes.
The embrittlement temperature is below -80℃ to adapt to extreme low-temperature environments.
3. Core Performance Characteristics of HDPE 7000F
3.1 Ultra-Low MFR and High Melt Strength
The 0.04 MFR value belongs to the ultra-low level among all commercial HDPE resin grades.
High molecular weight brings strong melt strength and stable bubble state during film blowing.
It supports ultra-thin film production from 0.006mm to 0.06mm without quality reduction.
3.2 Superior Strength and Rigidity
Balanced tensile strength and elongation enable films to keep rigid and non-collapsing shapes.
Finished film products bear heavy loads effectively without bottom cracking or local tearing.
3.3 Outstanding Weather and Low-Temperature Resistance
Professional antioxidant additives enhance its anti-aging ability for long outdoor exposure service.
It maintains intact toughness and flexibility even under continuous severe cold weather conditions.
3.4 High Adaptability to Low-Pressure Film Blowing
The recommended extrusion temperature is 180℃ to 230℃ for full and uniform plasticization.
A blow-up ratio of 2.5 to 4.0 ensures stable bubble operation on high-speed production lines.
This grade effectively lowers defective rates and improves overall film production efficiency.
4. Typical Application Scenarios for HDPE 7000F Films
4.1 Daily Packaging Film Products
Supermarket shopping bags made from 7000F feature good stiffness, printing effect and reusability.
Commercial and household garbage bags show great puncture resistance and anti-leakage performance.
Food packaging films meet food contact standards with non-toxic and odorless properties.
4.2 Agricultural Protective Film Applications
Greenhouse films block ultraviolet rays and maintain stable performance for long agricultural cycles.
Seedling cultivation films provide moderate strength and softness for seed growth protection.
4.3 Industrial and Special Thin Films
High-strength industrial films apply to product packaging and factory dust covering scenarios.
Special waste bags resist chemical corrosion for medical and industrial waste treatment use.
Ultra-thin 7000F films cut material costs while guaranteeing basic use performance standards.
4.4 Extended Diversified Application Fields
