Welding Rod & Electrode Protective Bags — 4×20 / 4 mil LDPE
4×20 inch, 4 mil LDPE flat poly bags for moisture-proof packaging of welding electrodes, filler rods, and stick welding bundles. Moisture is the primary enemy of welding electrode quality — the 4 mil barrier keeps E6013, E7018, and similar electrodes dry until use. FDA-compliant virgin LDPE, 1,000/case for welding supply distributors.

Key Features
- 4×20 footprint bundles standard 14–18 inch welding electrodes
- 4 mil heavy-gauge film creates critical moisture barrier for electrode integrity
- Protects E6013, E7018, and low-hydrogen electrodes from humidity absorption
- FDA-compliant virgin LDPE — strong bottom seal holds electrode bundles securely
- Heat sealable for airtight, tamper-evident closure
- 1,000/case for welding supply distributors and industrial MRO operations
Common Applications
- Stick welding electrode bundle moisture packaging
- MIG and TIG filler wire and rod protective storage bags
- Welding supply distributor shelf packaging and customer dispensing
- Industrial MRO welding consumables inventory protection
FAQs
- Why does moisture matter for welding electrodes?
- Hydrogen pickup from moisture in low-hydrogen electrode coatings causes weld porosity and cracking. A heat-sealed 4 mil bag maintains the original moisture content until the electrode is used.
- Are these FDA compliant?
- Yes. 100% virgin LDPE meeting FDA and USDA specifications.
