EcoLeaderPack makes custom 3D box non-woven bags with a rigid, flat base, sized to your food containers, cake boxes, and shoe boxes — at factory-direct wholesale pricing.
A 3D box non-woven bag is constructed like a folding carton rather than a traditional flat tote. Engineered with an integrated flat rectangular base panel and four perpendicular walls, it stands upright independently on busy restaurant packing counters, allowing workers to pack food orders with both hands free.
Box bags are made from recyclable polypropylene non-woven fabric, with ultrasonic or stitched construction. We make them to your container size, fabric weight (GSM), and print. Load capacity depends on GSM, handles, and base insert; see the weight guide below.

Request 1:1 Vector DielinesBox bags come in four main shapes, to match what you pack:
Engineered with an extra-wide rectangular floor where base width exceeds bag height. This horizontal geometry allows 10-inch to 14-inch pizza boxes, sushi catering trays, and hot soup bowls to sit side-by-side or stack flat without sliding to one corner.
Quote Wide-Base Takeout Bags
Designed with equal base width and gusset dimensions (e.g. 26×26 cm, 30×30 cm) to match standard 6-inch, 8-inch, and 10-inch bakery cake boxes. The cubic base keeps delicate cake boards level, leaving generous vertical headroom for decorative toppers and ribbons.
Quote Square Bakery Bags
Features a narrower rectangular floor combined with tall vertical walls, tailored for sliding in rigid shoe boxes, folded apparel garments, and premium department store gift sets without straining outer seams.
Quote Vertical Retail Bags
Produced on continuous automated rotary-die converting lines where box corners, gussets, and handles are molecularly bonded via ultrasonic heat pressing. Delivers thread-free clean edges, consistent tolerances, and maximum unit cost savings for large-scale procurement.

Every element of your 3D box bag is engineered to order in our factory, matching your product weight, moisture barrier needs, and brand identity.
Every bag is made around your container size, not a fixed catalog size. Send the outside dimensions of your container, the number of units per pack, and the load you expect. We offer three base options: a plain flat base for light goods, a 350–500 GSM greyboard insert for low-cost stiffness, and a washable 0.6–1.0 mm PP plate for heavy catering or wet food.
Customize Base ConstructionWe make box bags in four fabrics: PP spunbond for light, low-cost retail and takeout bags (70–100 GSM); PET / RPET polyester for higher tensile strength and a firm, self-standing shape; BOPP laminated non-woven for a wipe-clean, water-resistant surface with full-color printing; and PLA for plant-based projects, which we advise on case by case because cost and performance differ from PP.

Match your graphic artwork to the right factory printing method. We offer high-speed water-based flexographic printing for economical 1-to-2 color runs, precision silk screen printing for vibrant spot color logos, full-color laminated rotogravure printing for photo-quality 300+ DPI graphics on laminated non-woven bags, and heat transfer for detailed multi-color badges. Send vector artwork (AI/PDF) for free pre-press verification.

Choose from self-fabric loop handles for lightweight restaurant takeout, heavy-duty polypropylene webbing straps with cross-stitched "X-box" reinforcement for retail loads over 10 kg, or die-cut punch handles for automated box lines. Top closures include open tops for rapid counter packing, industrial Velcro strips, snap buttons, and heavy-duty nylon zippers for thermal temperature protection.

Fabric body, edge piping binding, and handle straps can be custom dyed to your corporate Pantone PMS color reference. Pre-production color proofing is verified via lab dips before bulk extrusion, guaranteeing brand color consistency across repeat orders.
Match Your Pantone ColorsPractical engineering answers to the most common procurement questions regarding 3D box bag load capacities, sizing formulas, and environmental compliance.
A flat tote or bottom-gusset bag bulges into a bowl shape when loaded, so flat containers tilt and slide toward the center. A 3D box bag has a separate rectangular base joined to four upright walls, like a carton, so it keeps its shape when loaded. At a packing station the bag stands on its own, so staff can load platters, cake boxes, and meal containers with both hands. In transit, items stay level across the flat floor, which helps prevent sauce spills, icing damage, and crushed corners.
To determine the ideal bag dimensions (Width × Gusset × Height), always measure the exterior footprint of your rigid container (or total stacked height for multi-tier catering boxes) and add practical clearance: add 15–25 mm (0.6"–1.0") to Box Length for bag Width, add 10–20 mm (0.4"–0.8") to Box Width for bag Gusset, and add 40–60 mm (1.5"–2.4") to Stacked Height for bag Height to accommodate top rim fold-over and closure headroom. If your order includes a rigid cardboard or PP bottom insert, the base plate is cut 3–5 mm smaller so it sits flat without distorting corner welds.
Polypropylene spunbond fabric is naturally hydrophobic and repels water droplets, light splashes, and ambient moisture. However, plain unlaminated non-woven fabric remains breathable; under direct hydrostatic pressure or at needle stitching holes, liquids can slowly seep through the fiber matrix. For food delivery, chilled catering, or iced drinks, we make laminated box bags with a BOPP outer film. The film keeps grease and condensation out of the fabric, so staff and customers can wipe the inside and outside clean.
Capacity depends on fabric weight (GSM), handle stitching, and how the base spreads the load. Ultrasonic box bags in 70–90 GSM fabric suit about 5–8 kg (bakery boxes, coffee trays, standard food deliveries). Stitched bags in 100–120 GSM fabric with X-box handles suit about 10–15 kg of heavier goods. We confirm the load at sampling. For dense stacks of food containers or shoe boxes, a 350–500 GSM paperboard insert or a washable 0.6–1.0 mm PP plate spreads the weight across the base and stops the bottom bowing.
Non-woven PP bags are made to be reused many times in everyday shopping and delivery. Actual life depends on the load and how the bag is handled. To preserve fabric structure and ultrasonic bond strength, bags should be spot-cleaned using a damp cloth, lukewarm water, and mild detergent; machine washing and tumble drying are not recommended.
Many markets set a minimum fabric weight or a reuse requirement for carrier bags, and 80 GSM or higher is often used as a reference. Rules differ by country and state, so tell us your destination market and we will match the GSM and documents to it. Box bags are made from virgin polypropylene (resin code 5). Unlaminated bags can be recycled where local facilities accept PP; for laminated bags, check local rules.
From initial container measurement to export packing, our streamlined 7-step engineering process ensures zero sizing errors and prompt delivery.
Direct answers to commercial packaging questions regarding minimum orders, full color printing, and container fitting.
A standard gusseted tote expands at the sides, but its bottom is formed by a center seam or pinch fold, causing it to round out under load. A 3D box bag features an independent flat rectangular base panel like a carton, allowing it to stand completely upright on counters and carry rigid containers level.
For payloads exceeding 5 kg, we incorporate a rigid 350–500 GSM cardboard insert or a washable 0.6–1.0 mm polypropylene plate. This base stiffener spreads downward weight across the entire base perimeter, preventing center sagging and keeping meal containers perfectly horizontal.
Automated ultrasonic box bags are ideal for large-scale orders of identical sizes where clean, thread-free edges and cost efficiency are prioritized. Machine-stitched box bags are recommended for smaller custom batches, heavier loads requiring "X-box" webbing handles, or bags with zipper closures.
Yes. Simply send us the exterior dimensions of your box or container. Our packaging CAD engineers calculate optimal operating clearance and generate a 1:1 vector dieline within 24 hours to verify fit before cutting raw material.
Only if the base dimensions accommodate the larger footprint. A pizza box requires a wide rectangular base with low height, whereas a cake box requires a cubic square footprint. We recommend sourcing two dedicated sizes to prevent smaller containers from shifting inside an oversized bag.
Yes. Full-color photographic artwork (CMYK) is applied via rotogravure printing onto a laminated BOPP film outer layer. For 1-to-2 color branding logos, water-based flexo and silk screen printing provide cost-effective alternatives.
