Frequently Asked Technical Questions about PE Packaging Bags
1. What is the difference between LDPE and HDPE in pe packaging bag production?
LDPE (Low-Density Polyethylene) offers greater flexibility and clarity, commonly used for food and light-duty industrial bags.
HDPE (High-Density Polyethylene) provides higher tensile strength and chemical resistance, ideal for heavy-duty and chemical storage bags.
2. How do pe coated paper pouches differ from pure PE bags?
PE coated paper pouches have a kraft or cellulose paper base laminated with PE, delivering enhanced stiffness and printability—a favorite for dry powders and eco-conscious applications.
3. What is the standard thickness range for PE pouch packaging?
Standard thickness ranges from 30 to 120 microns, customizable as needed for durability, barrier, and weight-bearing.
4. What are the relevant international standards for these packaging bags?
Most common: ISO 9001 (Quality), FDA 21 CFR (Food Safety), RoHS, and ISO 21898 (Flexible Intermediate Bulk Containers).
5. What QC and test methods are used?
Key tests: tensile strength (ASTM D882), puncture resistance, oxygen and vapor barrier (ASTM F1927), drop test (ISO 21898), and print adhesion.
6. What about recyclability?
Mono-material PE bags are 100% recyclable; multilayer (PA/PE, coated) require specialized facilities. All Junlan PE bags are RoHS-compliant and eco-labeled.
7. What is the minimum order and delivery period for pe packaging bag custom orders?
For the
pe packaging bag, typical MOQ: 10,000 units; delivery: 10–20 days depending on complexity and print colors.
