Flat Pouches
Flat Pouches – The Simplest Pre-Made Pouch for Samples, Sachets, and Lightweight Products
-
Flat pouches — also called three-side seal pouches — are the most basic pre-made flexible packaging format. Each pouch is sealed on three edges with an open top for filling, then heat-sealed closed after the product is loaded. With no gussets, no folds, and no standing structure, flat pouches use the least material of any pre-made pouch format, making them the most cost-effective option for lightweight, single-serve, and sample-size products.
-
Flat pouches are widely used for single-serve coffee sachets, sugar and seasoning packets, sample-size cosmetics, pharmaceutical powders, seed packets, tea bags, small snack portions, and promotional giveaway items. Any product that is lightweight, flat, or portioned into small quantities is a natural fit for this format.
-
Unlike pillow bags that are formed and filled on a continuous FFS line, flat pouches are delivered as pre-made bags ready for manual or semi-automatic filling. This makes them ideal for brands with multiple SKUs, small batch sizes, or products that require hand-packing — situations where setting up a high-speed FFS line is not practical or cost-justified.
-
Flat pouches can be constructed with BOPP/CPP for basic dry goods, PET/PE for moderate barrier protection, and PET/AL/PE or PET/VMPET/PE for products requiring full oxygen, moisture, and light barrier. Functional options include V-notch or straight-cut tear notches, hang holes for retail display, vacuum sealing compatibility, and zip-lock reclosable strips for multi-use products.
-
Every flat pouch is fully customizable — film structure, dimensions, seal width, and printing method are all matched to your product’s weight, barrier needs, and retail positioning. From 5g seasoning sachets to 100g snack packs, production scales efficiently from small runs to high-volume orders. Tell us your product type and target fill weight, and we will recommend the most practical specification for your packaging needs.

Actual capacity varies with product density and granule size. “—” indicates the size is not commonly used for that product type. Figures above are guideline references, not guaranteed fill weights.
The table shows reference fill capacities for our standard flat pouch sizes across powder, seasoning, coffee sachet, liquid, snack, and face mask products. Because flat pouches have no gussets or bottom folds, their fill capacity is lower than gusseted pouch formats at comparable external dimensions. Liquid products are measured in ml; solid products in grams.
Use these numbers as a starting guideline. If you’re unsure which flat pouch size best fits your target net weight, share your product type and target fill weight with our team, and we’ll recommend the most accurate size for your packaging needs.

The Voice of Global Customers Is Our Best Business Card
“Absolutely thrilled with my experience with this company🌟 I ordered 500 fully printed zip pouches across 14 SKUs with a soft touch matte finish – and WOW, they turned out incredible! The quality is top-notch: bright, vibrant colours that match my designer’s files perfectly, flawless zipper function, accurate cut lines on every pouch, and not a single reject in the whole order. Tear notches and hang holes are spot on. The thickness is ideal too! Huge shoutout to Quillion, my amazing sales rep, and their design team who helped fix typos and optimize the artwork. I was updated at every step, even receiving printing videos! Despite one box being misdelivered (not their fault), they reprinted and split shipping costs – super supportive even after delivery. Plus, the cost was almost 50% less than local Canadian quotes. Highly recommend – great service, great people, and exceptional results. Will be ordering”

“This was my first time ordering custom packaging, so I had a LOT of questions. They were patient with every revision and never made me feel like my order was too small. They helped me choose a pouch size based on my product weight, explained material options in simple terms, and even pointed out how to improve my design margins so text wouldn’t sit too close to the edges. I loved getting photos during production because it kept me calm. Everything arrived on time and looked even better in person. I really appreciate how supportive they were.”
Owen

“Professional, organized, and scalable.”
Clear process, quick quoting, and easy communication. They confirmed specs clearly and handled changes without drama. This is the kind of supplier you can scale with.
Daniel
USA
“Highly recommend—already planning the next order.”
Top quality, flexible MOQ, and very professional service. I’m not looking for another supplier—this is the team I want to grow with.
Noah
USA
“We had a product launch deadline, so timing mattered more than anything. They gave a realistic production schedule, confirmed every spec quickly, and didn’t overpromise. When we approved the final proof, they started production immediately and sent progress updates every few days. They also confirmed carton packing details and shipping marks so we could track everything easily. The shipment left on time and arrived earlier than expected. I’m very happy because they helped us hit our launch date without last-minute stress.”
Benjamin
Netherlands
“We wanted packaging that looks premium but still fits our budget. They gave us options and explained what impacts cost (material, finish, printing method) without pushing anything unnecessary. We selected a structure that works well for our product, and the final pouches look way better than I expected for the price. Print is clean, zipper is smooth, and the pouch stands well. Very good value and a smooth buying experience.”
Josie

“Best communication I’ve had with a packaging supplier.”
I’ve worked with several vendors—this was the smoothest. Clear updates, quick answers, and no confusion on specs. The final packaging matched what was promised.
Ethan
U.K.
“Fast turnaround + accurate delivery.”
They gave a realistic timeline, kept me updated, and shipped when they said they would. Packaging arrived earlier than expected and was packed safely.
Sophia
U.K.
“I’ve worked with several packaging suppliers and the biggest issue is usually inconsistency and slow communication. This team is different. The quoting was clear (structure, printing, lead time, packing), and they confirmed everything before production to avoid mistakes. They sent production photos and also confirmed the final carton quantity and packing list details. When the shipment arrived, the quality was consistent across cartons and matched our previous order. That reliability is exactly what we need for ongoing wholesale business.”
Michael
France
“One thing I really appreciated was how transparent they were. They didn’t just say “in production”—they actually sent photos and short videos: printing stage, pouch forming, and final inspection. They also confirmed the final approved proof one more time before starting, which prevented mistakes. This gave me confidence because I knew exactly what was happening. The finished packaging matched the approved design and was delivered on schedule. Highly recommend if you value clear updates.”

FAQs · We’ve Got You Covered
We’ve gathered the most common questions from our clients and provided clear answers. Whether you’re a first-time customer or a long-term partner, you’ll find everything you need here to save time and get quick solutions.
What is a flat pouch?
A flat pouch — also called a three-side seal pouch — is the simplest pre-made flexible packaging format. Three edges are sealed during manufacturing, leaving the top open for filling. After the product is loaded, the top is heat-sealed closed. It has no gussets or bottom folds, making it the most material-efficient pre-made pouch available.
What products are flat pouches used for?
Flat pouches are widely used for single-serve coffee sachets, sugar and seasoning packets, sample-size cosmetics, pharmaceutical powders, seed packets, tea bags, face masks, small snack portions, and promotional giveaway items. Any product that is lightweight, flat, or portioned into small quantities is a natural fit.
What is the difference between a flat pouch and a pillow bag?
A flat pouch is a pre-made bag — manufactured, shipped, and then filled by the brand using manual or semi-automatic equipment. A pillow bag is formed and filled in one continuous process on a high-speed FFS line. Flat pouches are better suited for small batches, multiple SKUs, and hand-packing operations, while pillow bags are designed for high-volume automated production.
What materials are used for flat pouches?
Common film structures include BOPP/CPP for basic dry goods, PET/PE for moderate barrier protection, and PET/AL/PE or PET/VMPET/PE for products requiring full oxygen, moisture, and light barrier. Material selection depends on your product’s shelf-life and barrier requirements.
What functional features can be added to flat pouches?
Options include V-notch or straight-cut tear notches for easy opening, hang holes for retail peg display, euro-slot headers, zip-lock reclosable strips for multi-use products, and vacuum sealing compatibility for freshness-sensitive items.
Can flat pouches be used for vacuum packaging?
Yes. Flat pouches with appropriate barrier film structures are fully compatible with vacuum sealing. This is commonly used for dried meats, jerky, herbs, and other products where removing air extends shelf life and maintains product quality.
What is the minimum order quantity for flat pouches?
MOQ generally ranges from 500 to 1,000 units, depending on pouch size, material, and printing method. We support small-batch orders for design testing before scaling to volume production.
How long does production take for flat pouches?
Standard production takes 10–15 days after artwork approval, excluding shipping. We confirm a specific timeline before production begins.
What printing options are available for flat pouches?
We offer digital printing for short runs and gravure printing for high-volume orders with lower unit cost. The clean, uninterrupted front and back panels provide full-surface printing space for brand graphics, product information, and regulatory compliance.
Are flat pouches suitable for food-contact products?
Yes. We offer food-grade film structures with soy-based or water-based inks that meet food packaging hygiene standards. Specific material certifications can be provided upon request depending on your target market’s regulatory requirements.
What materials are best for freshness and barrier protection?
For freshness-sensitive products, we recommend laminating aluminum foil (AL) or metallized PET (VMPET) into the film structure — these barrier layers block oxygen, moisture, and light almost completely. For lighter protection needs, standard PE or PET films with an EVOH barrier layer are a more cost-effective option.
