How Do I Choose Custom Flat Bags for My Product?
Flat bags are open-top, lay-flat PE bags without side gussets or a bottom gusset. The final material, size, thickness, printing and packing plan are confirmed against the written specification.
Material Types
- LDPE: soft and clear, often reviewed for apparel and lightweight products.
- HDPE: stiffer and abrasion-resistant, often reviewed for hardware and industrial products.
- LLDPE: tough and tear-resistant, often reviewed for logistics and electronics packaging.
Thickness and Size Examples
Common starting points can include 0.05 mm for lighter apparel packaging, 0.06–0.08 mm for many e-commerce applications and 0.08–0.12 mm for heavier products. These are examples for specification discussion, not universal industry standards; the final thickness is confirmed against product weight, handling and transport conditions.
Example sizes include 20 × 30 cm, 25 × 35 cm, 30 × 40 cm, 10 × 15 cm and 15 × 20 cm. Final width and height should account for the product, any closure or sealing area, tolerances and the intended presentation.
Applications and Options
Flat bags may be reviewed for apparel, electronics, hardware, e-commerce inner packing, retail display, warehouse classification and product protection. Depending on the specification, options may include anti-fog treatment, anti-static treatment, colour printing, matte or gloss appearance, a hanging hole, a label area and additional thickness.
For food-related projects, state the food-contact use and destination market in the RFQ. Material and document suitability must be reviewed for the specific project; the page does not make a blanket food-grade or certification claim.

Flat Bag FAQ
- What is the MOQ for custom flat bags?

- What is the lead time for flat bags?
- The production schedule is confirmed after the specification, artwork, quantity and packing plan are reviewed. No universal lead-time promise applies to every flat-bag project.
- Can flat bags be printed?
- Yes. Flexographic and gravure printing can be reviewed according to the artwork, colour count, print area and order requirements.
- Can flat bags be used for food-related packaging?
- Food-related use can be reviewed when the buyer provides the intended contact scenario and destination market. Material and supporting documents must be confirmed for the specific project before any claim is made.
- Can you make thicker flat bags?
- Thickness is reviewed against the product, handling and production specification. The suitable range and tolerance are confirmed in writing for each project rather than promised as a universal maximum.
