Explore practical guides from Dynaplast Mandiri on polyethylene film, HDPE, LDPE, LLDPE, micron thickness, packaging performance, quality control, resin markets, and industrial applications. The Knowledge Center is written for purchasing, production, engineering, QA/QC, and packaging-development teams.
What Is Anti-Block in PE Film? Why Plastic Bags Can Stick Together
Blocking occurs when adjacent PE film layers adhere too strongly during storage. Anti-block helps separate surfaces but performs a different function from slip.
What Are Slip and COF in PE Film? Why Film Can Be Too Slippery or Too Grippy
COF controls how easily PE film slides against itself or another surface. Values that are too high or too low can disrupt packaging and converting.
PE Film Thickness Tolerance: Why Micron Is Not Identical Everywhere
Nominal micron is a target thickness, not an identical reading at every point. Learn why gauge varies and how buyers can specify tolerance and sampling.
Puncture Resistance vs Tear Strength vs Tensile Strength: What Is the Difference?
Puncture, tear, and tensile properties describe different types of plastic-film strength. Understanding the difference helps buyers match PE film to application risk.
Why Do PE Bag Seals Leak or Peel Apart?
A leaking PE bag seal can result from machine settings, contamination, wrinkles, resin selection, or uneven film. Learn the main points to inspect.
Why Does PE Plastic Tear Easily? 7 Causes to Check
PE film that tears easily is not always too thin. Check puncture, resin formulation, gauge variation, film orientation, seals, defects, and handling conditions.
