2. Core Product Advantages
High melt strength for thick film and lamination production
This resin has high melt strength. It keeps film bubbles stable during production. It works well for thick films and high-speed extrusion lamination. It prevents uneven thickness, film breakage and gels, and lowers defect rates.
Great low-temperature toughness
It stays tough at -70 °C and will not turn brittle. Films made from this material do not crack in cold storage or outdoor areas. It is ideal for frozen food packaging and agricultural films used in cold regions.
High purity for smooth and clear films
It has few fish eyes and impurities. The finished films have smooth surfaces and good transparency. It meets strict standards for printed composite films, food contact films and high-grade packaging materials.
Safe for food contact and wide compatibility
This LDPE is safe to use for food contact. You can mix it with LLDPE or other LDPE grades to adjust film performance. It also serves as good base material for EPE foam products.
3. Main Application Fields
Packaging Films
Food packaging films, shopping bags, shrink films, composite base films, liquid packaging films
Extrusion Lamination Products
Paper-plastic lamination for paper cups and paper bowls, non-woven fabric lamination, release paper coating
Agricultural Films
Farm mulch films, greenhouse films, silage films, weed control fabrics
Foam and Extrusion Products
EPE foam sheets, cushioning gaskets, small blow-molded parts, general extrusion profiles
We can also provide customized grades with special blends, anti-static and UV-resistant properties.
4. Processing Guidelines
Recommended Process Parameters
Film blowing temperature: 190–220 °C
Extrusion lamination temperature: 190–220 °C
Blow-up ratio: 2.0–3.2
Foaming processing temperature: 185–210 °C
Processing Recommendations
1. Adjust processing parameters according to film thickness and equipment type.
2. Run small-batch tests before mixing it with other polyolefin resins, to check formula and processing stability.
3. This resin barely absorbs moisture. Drying is not needed under normal storage. Dry it at 60–70 °C for 1 hour if it gets damp.
4. Keep the resin in dry, cool and well-ventilated warehouses. Keep it away from rain, direct sunlight and open flames. Use stock in the order of arrival.
5. Frequently Asked Questions
Q: Is 18D0 suitable for food-contact products?A: It meets GB 4806.6-2016 for food contact materials. We can complete relevant tests to meet FDA and EU standards for export. Please keep batch COA for quality records.
Q: Can it be blended with LLDPE or other LDPE grades?A: Yes. Blending improves film toughness, gloss and processing performance. Do small-batch tests before mass production.
Q: What are the packaging specifications and minimum order quantity?A: Standard package is 25 kg per bag. One bag is the minimum order. We provide samples, LTL and FTL delivery.
Q: Is it suitable for foam processing?A: Yes. It works well for medium and low expansion foam products. It forms stable cell structure at 185–210 °C.
Q: What is the difference between 18D0 and 2426H?A: 18D0 has higher melt strength for thick film and lamination. It also has better low-temperature toughness for use in cold environments.
