Add your site voltage, automation preferences and delivery terms when you have them. The buyers who receive a usable quotation on the first attempt are not the ones who know machinery best — they are the ones who describe the product. This guide explains what a request for quotation for a custom bag-making machine should include, what information to add before a supplier can price it, and how to compare the quotes you receive. ## What Is a Custom Bag Making Machine RFQ? An RFQ — a request for quotation — is the written brief you send before a supplier prices anything. For a standard product, that brief is a part number. A custom bag making machine has no part number, because the machine is configured around the bag you intend to sell. Your RFQ therefore becomes the specification the machine is built to, tested against and accepted against. That is why two buyers can receive very different prices for equipment that looks identical in a catalogue. The difference is rarely the salesperson; it is the brief — how many bag sizes the machine must cover, how heavy the stock is, which handle format your market expects, and how much output the investment has to earn back. ### What Should You Send First, and What Can Wait? Send the product first and let the machine follow. A practical RFQ moves in this order: finished bag, production information, machine type, configuration, then price. If you already know which machine family you need, say so — but do not force a model number you found online onto a bag it may not match. Voltage, floor plans, spare parts lists and certification documents can come later, once the machine type is agreed. ![Custom bag making machine RFQ checklist with bag sample](https://www.bagmakemachine.com/wp-content/uploads/2026/10/custom-bag-machine-rfq-illustration-1-1200x675.webp) ## What Are the Minimum Specs for a Custom Bag Making Machine Quote? Six items are enough to open the conversation. | \# | Spec | What to send, with an illustrative example | Why the supplier needs it | | --- | --- | --- | --- | | 1 | Finished bag | Bag type plus a photo, drawing or sample — e.g. kraft square-bottom carrier bag | Confirms the production route: sheet-fed paper, non-woven or film | | 2 | Bag dimensions | Width × gusset × height in mm, plus bottom width and handle position if fixed — e.g. 210 × 90 × 300 mm | Sets the machine size range and the tooling | | 3 | Material | Stock name and grammage in gsm — e.g. white cardboard, 250 gsm, flat sheets | Decides the feeding, folding and sealing method | | 4 | Handle | Format, material, length and attachment point — e.g. round rope, 3 mm, knotted inside the mouth | Decides the handle module and its tooling | | 5 | Output | Bags per shift or per day, with your shift length — e.g. 20,000 bags across one 8-hour shift | Sets speed and automation level — and the price | | 6 | Destination | Country and city of installation — e.g. Valencia, Spain | Determines voltage, certification and shipping terms | Every example value above is illustrative. Send your own measurements, bag and material. With these six, a supplier can tell whether your project belongs to sheet-fed paper, non-woven or plastic film equipment, and can start narrowing the configuration. ZHENGWEI reviews 10–20 key parameters with a buyer before proposing a production system, which is a realistic number for a genuinely custom build. Ask the custom bag making machine manufacturer which parameters are still missing; a quotation that arrives before those questions have been asked is usually a stock model with your name written on it. ## How Do You Describe the Bag You Want to Make? ### Which Bag Dimensions Should You Measure? Four numbers decide most of a custom bag making machine: width (the bag’s face), gusset (the folded side panel that gives the bag its depth), height, and bottom width. Add the handle position if your customer fixes it. Measure an approved bag rather than a sketch, and send the smallest and largest size you intend to run — not one sample size. ![Diagram titled Measure the bag before you email showing a bag's front view with height and width arrows, a side view with gusset width, and a light blue note explaining gussets and other dimensions to send.](https://www.bagmakemachine.com/wp-content/uploads/2026/10/blog-09-inline-2-bag-measurements.webp) Sizes eliminate models faster than price does. The published crease-free paper range covers 200–540 mm wide, 70–200 mm gusset and 200–420 mm high on the standard model, with a [mini machine](https://www.bagmakemachine.com/product/zw-a10-mini-fully-automatic-crease-free-sheet-feeding-paper-bag-making-machine-mini/) for 150–350 mm formats and a [large machine](https://www.bagmakemachine.com/product/zw-a15max-fully-au-tomatic-crease-free-sheet-feeding-paper-bag-making-machine-max/) up to 600 mm wide. If your bag sits outside every published range, that is a custom tooling question, and it belongs in the first line of your RFQ. ![Large white and blue industrial bag-making machine with dark panels, a mounted control screen, and a connected side frame.](https://bagmakemachine.b-cdn.net/wp-content/uploads/2026/07/A10MINI.jpg) PAPER BAG MACHINEZW-A10 Mini Fully Automatic Crease-Free Sheet Feeding Paper Bag Making Machine ZHENGWEI ZW-A10MINI is a fully-automatic crease-free sheet-feeding paper bag making machine designed for mini luxury packaging.

Two buyers can both ask for a “square-bottom bag” and mean different machines: one wants a flat base glued square, the other a wider bottom with a card insert. A physical sample sent by courier removes the guesswork, and a dimensioned drawing is the next best thing. A photograph works if it shows the bag standing, the bottom from underneath and the handle attachment close up, with a ruler in frame. ### What Bag Type Should You Name? Name the application, not just the shape: retail carrier, luxury or gift bag, wine bag, food delivery bag, insulated bag, non-woven box bag or RPET bag. Say who the end customer is — a supermarket, a bakery chain, a jewellery brand — because that decides the finish quality the machine must hold, and whether the bag runs on paper or on [non-woven or film equipment](https://www.bagmakemachine.com/wp-content/uploads/wp-mfa-exports/taxonomy/product_cat/non-woven-bag-making-machine.md). ## What Do You Send About Material and Handles? ### How Do You Specify Paper or Fabric? Name the stock and the grammage. Grammage is written in gsm — grams per square metre — and it is the fastest way to tell a supplier what a custom bag making machine must handle, because paper feeds and folds differently at 180 gsm and at 300 gsm. State whether the material arrives as flat sheets or as a roll; that choice alone separates the two main paper machine families. Add any coating, lamination or foil finish. ZHENGWEI’s sheet-fed paper models run 180–300 gsm stock, and its non-woven and film equipment covers roughly 55–140 g laminated fabric and film. If your material sits outside the range you are offered, ask what has to change. ### Which Handle Details Change the Machine? The handle is the most underestimated line in an RFQ. Round rope, flat ribbon, cotton rope, ribbon with a card insert and dual-strap handles need different feeding and bonding stations. Send the format, its material and thickness, the length, and where it attaches — knotted through punched holes inside the mouth, or bonded to the bag surface. If your customers order both cord and ribbon bags, say so before the quotation. One platform can run both handle formats without changing the die head — the [ZW-A11 Pro](https://www.bagmakemachine.com/product/zw-a11-pro-multi-functional-twist-rope-ribbon-paper-bag-making-machine/) is built that way — and asking for that capability at RFQ stage costs far less than discovering the need after installation. ![Large white and blue industrial bag-making machine with control screens, open cabinet doors, and metal roller components.](https://bagmakemachine.b-cdn.net/wp-content/uploads/2026/07/a11Pro-2.jpg) PAPER BAG MACHINEZW-A11 Pro Multi-functional Twist Rope & Ribbon Paper Bag Making Machine ZHENGWEI ZW-A11Pro is a multi-functional twist rope and ribbon paper bag making machine designed to handle both flat and round cord paper bags on a single platform without changing the die head.

Send volume first: bags per shift, your shift length, and how many days a week you produce. Let the supplier convert that into a machine speed, then test the figure against the published range for the model quoted. The crease-free paper range is published at 35–45 bags per minute across the family. Peak speed and sustained speed are different numbers, so ask which one the quotation assumes, and on which bag. ### What Automation Level Do You Want? Say which automation you need instead of leaving it blank. Automatic parameter matching, recipe storage for repeat jobs, remote diagnostics and inline handle inspection all change the configuration and the price. A buyer who stays silent usually receives the cheapest configuration that makes the bag, which is rarely the cheapest to run. ### What Site and Market Details Belong in the RFQ? Add the facts the machine has to live with: voltage and frequency at your site, the floor space you can give it, compressed air, how trim and dust are handled, and how many operators will run it. Then name the destination country and any certificates your market requires — CE is the usual one for the European Union. Also state the language you want for the HMI (the machine’s touch screen) and for the manuals. ## What Commercial Terms Should the First RFQ Include? Say how you are buying the custom bag making machine: one unit, several units, or a full line with auxiliary equipment. Then confirm the trade term you want quoted. EXW means ex works — the machine is collected at the factory — while FOB means free on board, loaded at the port; the two prices are not comparable, so ask every supplier for the same basis. Add the delivery port, your target timeline, whether a spare parts package sits inside the price, and your preferred payment structure. If you have a budget range, share it: a supplier who knows the limit proposes a configuration inside it instead of the largest machine available. ## What Should You Not Guess Before You Send an RFQ? - Do not choose the model first. Describe the bag and let the range decide the model. - Do not ask for “your price list”. There is no list price for a configured machine. - Do not copy another buyer’s specification sheet. Their bag, material and market are not yours. - Do not leave the material out. Grammage and sheet-versus-roll decide the machine family. - Do not send a bag size you have not measured. Approximate sizes return approximate ranges. - Do not expect a firm price before a sample. A price without a sample is an estimate with a date on it. ## How Do You Compare the Quotations You Receive? Compare each quotation against your own RFQ, line by line, not against the other quotations. Check the bag range against your smallest and largest size, the material range against your stock, whether the handle tooling is included, whether throughput is quoted as peak or sustained, and which automation is inside the price. Then read what is excluded — freight, foundations, utilities, installation, training, spare parts and certification are the usual omissions — and confirm who pays for engineer travel if commissioning runs long. ![Paper bag machine quotation comparison checklist and bag dimensions](https://www.bagmakemachine.com/wp-content/uploads/2026/10/custom-bag-machine-rfq-illustration-2-1200x675.webp) Finally, ask for the configuration sheet behind the custom bag making machine price. ZHENGWEI publishes [7–10 days for on-site installation and commissioning](https://www.bagmakemachine.com/services/), a 12-month full-machine warranty and a 24-hour technical response, with the commercial terms summarised in its [support FAQ](https://www.bagmakemachine.com/faq/). Compare those answers across suppliers the same way you compare the price. A lower price attached to a configuration that does not match your bag is not a lower price; it is a later problem. ## Conclusion: Send the Bag, Not a Sentence Everything that makes a custom bag-making machine quotation accurate — bag type, dimensions, material, handle, output, destination — is information you already hold. Send it in the first message, confirm the rest before the price is fixed, and compare the replies on the same specification. The suppliers worth keeping are the ones who ask for the missing details rather than filling the gaps themselves. **Next step:** send your bag sample or drawing, dimensions, material and grammage, handle format, required output per shift and destination country to [request your custom bag making machine quotation](https://www.bagmakemachine.com/contact-us/). Ask for the configuration sheet, the machine’s size and material range, and the [published model range](https://www.bagmakemachine.com/wp-content/uploads/wp-mfa-exports/taxonomy/product_cat/crease-free-paper-bag-making-machine.md) alongside the price.
