A Complete Courier Bag
Production Line,
Matched and Tested.

A standard 3-stage line (3-layer blown film + 6-color printer + single-lane bag machine) typically requires approximately 15–20 metres in line length and 6–8 metres in width, depending on the specific models selected and whether inline or offline printing is used. Ceiling height requirement is driven by the blown film machine's bubble tower — typically 7–9 metres for the LQ-ABA-1400 series.

A 3-layer ABA structure gives you two independent control points that a mono-layer machine cannot provide. First, the outer A layers can be virgin LLDPE for consistent seal performance and print surface quality, while the centre B layer carries PCR content or colour masterbatch — isolating any visual or mechanical variability from the surface. Second, you can run a stiffer, higher-strength outer layer formulation without affecting the core layer's cost structure. For courier bags specifically, this means better drop-impact resistance at the same overall film thickness.

Most courier bag orders fall into two categories: 2-color (brand logo + barcode area in one or two spot colors) and 4–6 color (full brand livery with process color). Plain white or grey bags with no print are also common for logistics companies that apply their own labels. If your target market is primarily small e-commerce sellers, a 2–4 color machine is usually sufficient. If you are supplying large brand-name e-commerce platforms or logistics companies with complex brand guidelines, a 6-color machine gives you the flexibility to take on any order without turning work away.

Dual-lane (two side-by-side bag lanes on one machine) doubles output to approximately 400 pcs/min, but only for bag widths that fit within each lane's maximum width — typically up to 420 mm per lane. If your primary bag size is a standard small or medium courier bag (250–380 mm wide), dual-lane is the most cost-effective way to double output without buying a second complete machine. If you regularly run large bags (500 mm+ wide), single-lane is the correct choice as the bag width exceeds what dual-lane can accommodate.

Yes. The LQ-SSCB series courier bag machine includes an integrated peel-and-seal (self-adhesive strip) application system as standard. The strip is applied inline during the bag-making cycle. A double-seal option (two strips for resealable bags) is available as a configuration upgrade. [NEEDS CLIENT VERIFICATION — confirm double-seal availability on specific models]

Yes, within the machine's width and length range. Changing bag size requires adjusting the seal bar position (width) and the cutting pitch (length). On servo-driven models, length adjustment is done via the control panel without mechanical changes. Width adjustment requires a physical repositioning of the side-seal bars, which typically takes 20–40 minutes. If you run many different sizes frequently, discuss this with our engineers at the configuration stage — the machine can be set up to minimise changeover time for your specific size range.

The bag making and printing stages are compatible with PBAT/PLA film. However, the blown film extrusion stage requires a dedicated biodegradable film machine — PLA/PBAT blends cannot be run on a standard PE blown film machine due to different screw geometry and temperature control requirements. If your target market requires certified compostable courier bags, the film extrusion stage must be specified as a biodegradable specialist line. See the LayerQuestar Biodegradable Film Machine page for full details.

Standard after-sales support includes: remote installation guidance via video call, English-language operation manuals for all three machines, and a 12-month warranty on parts under normal operating conditions. On-site commissioning by a LayerQuestar engineer is available as an optional service — lead time and cost depend on your location.
