Why choose our back seal bags for household supplies? The design balances protection and presentation perfectly. The back seal construction features a single vertical seal at the back of the bag, creating a pillow-shaped cavity ideal for lightweight to medium-viscosity or powder-based products, compatible with manual or automatic filling lines. Our material structure uses industrial-grade, chemically resistant laminated films—typically PET/AL/PE or PET/VMPET/PE—providing outstanding oxygen and moisture barriers (OTR ≤0.5 cc/m²·day, WVTR ≤0.8 g/m²·day), chemical resistance, and puncture strength. We offer full-color rotogravure printing up to 10 colors, matte or gloss finishes, holographic effects, and custom die-cuts. Every batch undergoes strict quality control: leak testing per ASTM D3078 (zero bubble tolerance), seal strength verification (≥35 N/15mm), and material migration analysis (GC-MS) to ensure no harmful transfer to household product contents. Optional eco-friendly structures include recyclable mono-material PE or compostable PLA (ASTM D6400 certified). With lead times of 5–7 days for blank samples and 15–20 days for mass production, our bags support both small brands and enterprise lines, ensuring consistent seal integrity, vibrant print registration (±0.5mm), and reliable performance from filling to unboxing.
