Q2: How is the bag's barrier property evaluated?

A: Barrier properties in flour packaging bags are tested using MVTR (Moisture Vapor Transmission Rate) and OTR (Oxygen Transmission Rate) measures as per ASTM E96 and ISO 15106 standards (ASTM Standards).

Q3: What specifications are vital for food contact compliance?

A: Materials must meet FDA (21 CFR 177) and EU Food Contact regulations (EC No. 1935/2004), ensuring no migration of contaminants (EFSA).

Q4: How are flour packing bags sealed for maximum freshness?

A: Most industrial bags use hot-melt glue, pinch-bottom, or sewn closures. Consumer-facing flour bag design may include resealable zippers or valve-type closures.

Q5: What is the typical thickness of a flour packaging bag?

A: Thickness ranges from 80–170 µm, depending on the material and application requirements for tear/stress resistance.

Q6: Are paper bags for flour packaging environmentally friendly?
