Square Bottom Liner Bags Introduction
Introducing our premium Clear PE Square Bottom Liner Bags – the ultimate packaging solution for businesses requiring sturdy, spacious, and transparent containment. Unlike flat bags, the square bottom (gusseted) design allows the bag to stand upright and hold its shape, providing a larger usable capacity and better stability when filled.
Manufactured from high-grade Virgin Polyethylene material, these liners offer excellent clarity for easy inventory identification. Whether you are packaging bulky textiles, industrial components, food ingredients, or recycling materials, our Square Bottom Liner Bags provide reliable puncture resistance and tear strength. Plus, we offer fully customizable sizes (Length, Width, Bottom Gusset, and Thickness) to ensure a perfect fit for your bins, boxes, or pallets.

FAQ (Frequently Asked Questions)
Q1: What is the minimum order quantity (MOQ) for custom sizes?
A: For custom dimensions (width, length, or thickness), our MOQ is typically 1000. However, if you need a small trial run, please contact us to discuss sample options.
Q2: How do I measure the correct size for my container?
A: For a square bottom bag, measure the Width (W) across the opening, the Depth (D) of the gusset (side fold), and the Length (L) from the bottom to the top edge. We recommend adding 5–10 cm to the length for overhang to secure the liner.
Q3: Are these bags food-safe?
A: Yes. We use food-grade virgin PE material upon request. Please specify “Food Grade” in your order notes or inquiry to ensure we use the appropriate resin.
Q4: Can I print my company logo on these bags?
A: Absolutely. We support custom flexo printing (up to [e.g., 4 colors]) on the bags. A separate setup charge and higher MOQ may apply.
Q5: What is the difference between a flat bag and a Square Bottom Liner Bags?
A: A flat bag has no side folds, which limits the volume when opened. A square bottom bag has gusseted sides that expand to create a rectangular base, allowing the bag to stand upright and hold much more volume than a flat bag of the same width.
