Understanding LD251 LDPE Resin Selection and Applications
1. This resin will be used for food-contact paper cups. What is its odor level?
Zhongtian Hechuang LD251 is formulated for food-contact extrusion coating and is generally low in odor. Odor can change a bit with each batch and coating conditions. We suggest getting a sample to test it under your own line conditions before starting full production.
2. How is the adhesion performance on kraft paper and aluminum foil?
This grade is designed to bond well with both kraft paper and aluminum foil in standard extrusion coating setups. Actual adhesion strength depends on coating temperature, line speed, and substrate treatment. So, the best way to confirm results is to run a trial on your own equipment.
3. Is there any difference compared to other LDPE extrusion coating grades?
Zhongtian Hechuang LD251 is a general-purpose extrusion coating grade. It has a melt flow rate and density that work well for paper and foil lamination. LDPE coating grades differ mainly in processing window and adhesion consistency. This is true when comparing production runs. Share your current grade with us and we can walk through the comparison.
4. How many kilograms of sample can you provide for a machine coating trial?
Sample quantity depends on your trial setup and equipment. For most machine coating trials, we can arrange enough material for a meaningful test run. Contact our team with your line details and trial goals, and we will confirm the exact quantity available.
